Further 4G + 4G+ testing in regards to my post
I went back down and moved it as far down as I could get to get a better angle, I only improved the RSRP by about -2 or -3 but wow it made a difference to the upload Big Grin 
Even if they do enforce the speedcap i'll be buying the one for 35 euro a month with no speed cap if it's THIS good. The cell seems to be lightly loaded all the time which is odd, I even saw -4 RSRQ while setting up the new position Big Grin  It's absolutely perfect for my streaming too because I'm getting 25-30 Mbps Upload now at 7pm  Cool  Still no sign of three fixing their mast/whatever is wrong. It's a shame cuz it was working so well with triple CA getting similar upload as well but went downhill since that stormy day. 
The SINR also peaked at 24 which is by far the highest i've ever seen, moving it really helped the upload like I was initially disappointed with the 14 Mbps Upload I was getting but now that i'm hitting 30 Mbps upload after moving it i'm over the moon.

I just started using chrome remote desktop to check my signal while being down the field so it saved me alot of hassle running up and down too. Since I was getting signal with phone anyway.

Before I was maxing out around 14-15 Mbps upload at any time with vodafone in initial spot. It's insane how much moving it helped the upload.
So do you think the R11e4G is my bottle neck? What do you that cell is capable of if I had a gigabit port on there  Tongue

Also how come it's so lightly loaded? Is each sector fed with a certain amount of bandwidth or is it for all 3 , maybe since it's pointing toward me away from the town , that i'm basically getting the cell to myself, im not complaining though I hope it stays that way

Based on your earlier testing where you got around 3Mbps on Vodafone, this makes me wonder if the more data-dependent customers switched to another network. Wink This happened with Three around our area back in 2017 when there was a severe backhaul issue with the Three network serving most of the area, i.e. streaming was practically impossible after 8pm regardless of the area.  This meant when Three fixed the issue at the start of 2018, I had a pretty solid performing connection throughout the evening, e.g. 40+ Mbps in nearly every speed test.

Try selecting band 20 on that R11e4G and see what speed tests you get.  If your dish had a gigabit port and a cat 6 modem, the sum of the band 20 and 3 test results would give you roughly what the 4G+ speed would achieve and that's at peak time. Big Grin

That sure was awful bad timing with Three between site hackhaul issues and traffic shaping, particularly after purchasing the Chateau LTE12 and expensive LOG antennae. Cry 

The triple CA still works here with my Chateau LTE12, but still waiting on word back from MikroTik about the link flapping.  I really hope Three fixes that Arranmore mast.  At the moment, the issue sure makes a mockery of their recent RTÉ TV advertising about them delivering high speed connectivity to Arranmore!  

I've now run OpenVPN tests with hide.me and it's certainly faster than SSTP.  The following are TestMy and Speedtest.net about 8pm today without the VPN. Unsurprisingly, it took multiple attempts due to the Chateau LTE12 link flapping bug:

hide.me using OpenVPN protocol.  In this case I was trying OpenVPN UDP with their socks proxy:

Finally, my current connection on the Huawei B525 with Kilcar.  Slower, but not flapping like a bird.  Tongue

The R11e4G seems completely useless on band 20, RSRP varies so much and its much worse signal than the band 3. Anywhere from -110 to -120 + and the RSRQ is -18  and spikes to -60 RSRQ which seems crazy, the SINR is also fully negative. I guess the mikrotik is no good for band 20 , I remember 4G+ with LTE 6 was useless as well. Shame I can't get a proper test of that. 

Saw that TV ad as well , few days now and still abysmal speeds, so much for that Big Grin unless arranmore itself isn't affected. Your speeds with the vpn seem really good, Why do they do traffic shaping in the first place? or why does the vpn work WAY faster than normally using it, Like whats the point of it? It just makes the speeds really slow. I was thinking maybe just the PAYG sim was limited on the download since I remember hitting 25 Upload in one test. But changed my plan to unlimited X plan and it was the best decision I ever made now that it's by far the best for upload. On the inspector tool as well it showed a much more consistent , stable upload without any FPS drops, unlike when I was doing it with Threes. 

Do u think the cell is completely empty if i'm getting RSRQ as low as -4 and SINR of 24 Big Grin ? 
I might be tempted to buy a very long extension lead and make a water proof place for router if speeds are really this good but il hold off to see if Three fixes anything. I need to find out if theres an O2 band 3 cell in dungloe as well.
Do those dual sim routers combine the speeds of two operators just like carrier aggregation or how do they work?


Update: Of course there had to be some problem, seems to be severe latency issues for some reason , I'm getting spikes from 40 - 100+ on testmy.net , was unplayable on call of duty and I got disconnected several times while the speeds remained great and consistent 80 down 28 up. I wonder why the latency is so poor , I get better latency on band 20 on 4G with three. And For example i'd get 50-60ms average on band 3 on Three (before the issues). I had my hopes up there and unfortunately theres packet loss and huge spikes.
As of later last night and today ping is normal again but i'm afraid it'll happen again at peak time because thats when it was happening even though the RSRQ was dropping down to -5. I can just hope its a once off.

Got an answer from a Three support rep and basically saying theres no issue reported with the arranmore mast so thats great Cry 
Doubt it'll ever get fixed at this rate after buying the LOG's and router for it.

Signal dies out + speeds at 2am again  and still ongoing at 3am , same happened last night , what would that be?

To further update on the vodafone issues, there is packetloss and severe latency issues from about 8pm-12am which is peak time I guess , but outside of that it's super smooth and runs really well. I dont understand why it gets so bad at peak time even though the RSRQ only goes up to like -8 at most and the speeds dont get affected at all. I tried vodafone livechat and it was a waste of time, they dont have a clue what they're talking about / understand your point at all. Same with Three live chat. Is there anything on my end that might help or is it just going to be another issue with vodafone. Its sad because the vodafone connection is literally perfect Cry super fast download and upload 70-80 always and 20-30 up. But of course there had to be some problem - > latency at peak time Big Grin  I tried the eir sim because I need some kind of connection to game on for good latency and so far that was a disaster too, lots of spikes, though its on the same mast so maybe that's why it suffers the same issues. Only band 20 with Three is somewhat usable for games and it's still really laggy.  Couldn't pick up the eir 4G mast with my LOGS ill probably have to tilt them up and try again/ I used to just swap to 2100 Mhz 3G for gaming and i'd be getting solid 30-50ms no issues until lately.
Feels like an impossible struggle, one thing works amazing then the next minute theres an issue.
Reply
I reckon you had that sector all to yourself whenever that RSRQ was within -6dB. Smile

Dual SIM routers cannot aggregate the bandwidth, at least not without a third party service like Speedify that doesn't seem to work with 4G.  Their main purpose is to provide a backup connection if one LTE link goes down.  For example, you could have Three as your main SIM and Vodafone as a backup, particularly in a moving vehicle where some areas only have a signal on either network. Like with two PC LAN connections, you can also route certain traffic over each SIM, e.g. streaming server IP range over one SIM and everything else over the second SIM, assuming the router is capable of establishing simultaneous LTE sessions. 

Pity to hear about the latency spikes on Vodafone. Sad  Going by your ping tests, those are more severe than the link flapping issue with my Chateau LTE12.  Here, it's one ~400ms spike each time the link flaps and mostly 20-40ms pings in-between.  I have seen people report similar issues on Boards before with Vodafone's fixed broadband in some areas.  However, those spikes look like a flapping link somewhere along their route, which could be the microwave backhaul to the mast. 

As for Three, if it was me, I would be tempted to take a trip over to Arranmore with a laptop and a portable Hotspot on the Three network.  Then capture some footage showing it struggling to stream HD, download/upload files at a snail's pace and a speed test, then post a YouTube video titled something like "Speed tests on Three in Arranmore".  That would soon grab their attention. Big Grin 

My guess about Vodafone's signal strength dropping at 2am would be for energy saving.  It would be interesting to monitor it overnight, e.g. have a screen recording to a file and see what time the signal comes back.  If it lasts several hours each night, it's likely they are trying to cut the electric running cost of the masts by running them at low power. 

My best guess for Three's traffic shaping is to limit bandwidth to IPTV, unofficial streaming services and downloads.  Unofficial/pirate IPTV services tend to be bandwidth hogs as these are often just captured at a constant bitrate, which could be like 8Mbps for HD, compared to 2-4Mbps typically of prerecorded on-demand streaming such as YouTube. 

If the traffic shaping limits individual connections to let's say 4Mbps, that literally blocks all unofficial HD streaming/IPTV encoded at higher bitrates.  As for downloading, most people just let their browser handle the download rather than use a multi-part download accelerator to mimic how Ookla runs its speedtest.

As for the VPN getting past traffic shaping, it only seems to be select protocols that work, e.g. SSTP, OpenVPN via TCP or UDP with a socks proxy.  Most privacy VPNs don't offer these protocol configurations (at least not PIA or Keep Solid) even for those that do, most people just connect with the default configuration, which doesn't get past the traffic shaping. 

I remember you mention about Starlink - I recently saw a video on Starlink's potential speeds and latency, so let's hope it's not too far away from going live.  I'm sure they will give a big shake up to the mobile operators to upgrade their rural network... Wink

I have another odd problem, maybe one of my antennas are broken, the one I have marked with tape, when I use it individually the signal is much worse. I also put the vertical LOG back up, the old one) and combined it with the working lpda. 4G speeds didnt change at all, still some issue wrong. But I tried getting 2100 Mhz 3G to work doing the same thing testing each antenna on the LTE12 but it'd always read 100+ RSCP and never good latency. I took out the B525, speed on 4G still super poor so rules that out too. But the 2100 Mhz 3G actually works on the B525 using the "better" LPDA. But it doesn't work with any antenna on the LTE12 ... theres always lags. 
I wonder why the LTE12 wont pick up the better reading of the 3G, I'm fairly sure it worked initially too when I got the router but not anymore.

From looking at your Chateau LTE12 3G screenshot, EARFCN 3010 is 942MHz, i.e. 900MHz, 3G band 8.  In fact, it should say UARFCN for 3G. Wink You can try unchecking band 8 to force it on band 1. 

From testing my Iskra LOG antennae one at a time, it appears one dominates over the other, although possibly mine need adjustment as I originally aligned them with both attached to the router.  For example, with just one antenna connected, the two band 3's hover around -99dBm to -102dBm, but with the other antenna, it's around -112dBm to -116dBm.  Despite the massive signal difference, the throughput appears to be roughly spread across both ports, i.e. disconnecting the weaker antenna (which I've on port #2) cuts the speed in half with the Vultr and VPN tests. However, if I attach only the weaker antenna to port #1, I get about 1/4 the speed of both antennae.

MikroTik finally came back saying they are still looking into the issue and basically asked me to export another support debugging file with band 20+3 configuration.  To my surprise, I seem to get better performance with 20+3+3 now, probably due to more traffic on the covid band (#1) as I call it. Big Grin 

With the latency issues here even on 4G+ in the evening, it looks like I'm going to need a separate LTE connection for our VoIP phone line even if MikroTik fixes the LTE flapping issue.  The following was with the Huawei B525 on band 20+1, Sunday around 10pm:

Unfortunately , Still having a lot of issues with trying to get my stream + gaming setup to work. So far It's starting to look like both LOG's have some kind of issue with them, The 2100 Mhz 3G was at least working on the B525 but its signal also became super weak one day all of a sudden and I dont even think it was raining. I put the old LOG back in the tree mounted lower down and it improved the signal. The initial signal dropped from -84 RSCP to -97 with the two LOG's at the top. Then the older LOG on its own was -89 RSCP. So I'm unsure what to do with my current setup now at all. 

With vodafone it's a really weird one and a shame really because its by far the best/most consistent connection of them all. Off-peak its flawless,  the best connection I ever had,  90 down and 25-30 Up. but peak time + late at night when they seem to lower the power to save electricity or something is when its really meh.  The weird thing is the speeds remain fine, barely any slower and i'll still get 80 down and the usual 25-30 up but the latency goes haywire. And my stream becomes unstable from about 8pm onwards to midnight or 1am ish. Why would the speeds remain the same but the latency + stream starts becoming unstable. The connection is amazing for downloading stuff, I'm able to download at 10 MB/s any time of day except for whenever they lower the power, even at peak time when the latency and stream has issues, download works fine. 

LTE12 for some reason doesn't work with band 1 3G properly anymore either , no matter what antenna I use, I only managed to get it to select it one day by constantly selecting band 8 and 1 and it finally recognized the correct signal and it worked fine but when i rebooted the router the signal was reading way weaker than it was when it finally worked and it was not usable. another weird issue.  
I have no idea what to do next in terms of setup because at the minute, it's either stream earlier and avoid the peak time which isn't ideal at all, even though it'll work flawless that way. Or try seeing if theres any other way of setting things up to eliminate this limitation.  Example, do you know if I got something that is specifically for band 1 3G like some kind of antenna - use that to game on / most traffic -   // find another that can provide at least 10 mbps upload when the vodafone one cant (at peak time) , any ideas? Tongue 
If only the vodafone one kept working like it does off-peak... would literally be the ideal setup , my ping is great and the stream looks great. But of course there had to be something wrong with my luck Big Grin 

I think i've been extremely unlucky in terms of the antennas, unless something really is still wrong on Three's end but they're denying anything is. I tried , they said they'd investigate it or something but haven't heard back.

You can see in the screenshot, it works flawlessly until peak time and then all kinds of issues with stability start, people were complaining about stuttering or buffering, even though in my OBS my bitrate seemed fine, and the upload speed was enough. Some kind of traffic issue at peak time? would explain the latency issues on that connection at peak time too. Probably nothing I can do about it?

The next day it's dry outside, I suggest detaching the extension leads and check the connectors for any moisture or corrosion.  If they appear dry, try attaching the LPDA antennae directly into the Huawei B525 temporarily placed outside (without the extensions) and see if there's much difference. A few dB stronger is fine, but if it's over 10dB stronger on band 1 or 3, then the extension cables have water/moisture ingress.

If the antennae improve after a day or two of dry weather (it can take a day for moisture trapped between parts to dry out), I suggest contacting the shop about the issue.  You can also try covering the antennae in plastic to keep the rain off, however, this will make them more vulnerable to wind moving them off alignment.

The Vodafone latency issue is quite likely a router or firewall upstream with high CPU utilisation.  Just in case it's a peering issue with Vodafone, try testing with the CloudFlare Warp+ VPN as its traffic will likely go over different peering.  If the Warp+ VPN doesn't help, then Unfortunately I don't think there is much you can do with the Vodafone connection.

I really feel awkward about recommending any further antennae, especially having tried so many.   Cry  The only band 1 specific antenna I know of is the following on the Dipol website.  You would only need the one antenna for 3G:
https://www.dipol.ie/cellular-systems/gs...-plug.html

Based on the description, it looks like new-old stock, particularly when they mention a laptop with a UMTS card.  It must be 10 years or so that I recall seeing a PCMCIA data card!  Pity it doesn't go down to 1.7GHz to cover band 3.  However, this does mean the 16dBi claim is likely true as narrow band antennae generally have higher gain than multi-band or wideband antennae of the same dimensions.  

Does your video stream need to have very low latency or can it be delayed a few seconds?  If a few seconds of latency is fine, there may be an option in OBS to buffer the output to allow for network fluctuations.  I know YouTube has this capability as I've seen some live streams say "Optimised for low latency" and others say "Optimised for normal latency" where there's a few seconds delay between when it broadcasts and when I see the picture on my end.  Big Clive (a bearded technical YouTuber on the Isle of man who does electronics teardowns/creations) broadcasts over Three 4G and sometimes his live streams intermittently go robotic/jittery as he seems to broadcast in low latency.


For your MikroTik, you can try changing its antenna setting to "Main" when you use 3G mode.  The main (port #1) antenna is the one behind the signal bars, like the Huawei B525.

Ill try WARP+ tonight to see if it helps with vodafone. I bought the 3G antenna since its only 49 euro and it's alot higher gain than the LOG's for band 1 3G so maybe it'll improve my ping even more. I think I probably do have that band 1 mast to myself. Ping is super low in comparison to any other band 3G or 4G. Would that antenna work for band 1 4G too?

I'll try it this evening / tmoro with the cables to see if it makes any difference too. I wouldn't mind some delay but nothing too crazy so I can still interact with viewers . I currently was using NVENC (new) for my encoder since it works best with RTX series GPU's since it has a seperate hardware based encoder so theres basically no performance hit in comparison to using the CPU bound x264 where I would feel a difference on the medium preset for example even with a 9900k , But x264 has a custom buffer option, is this what I'd need to adjust for it? or it an overall stream delay setting on the platform / obs? I use the CBR option in both as well, I never really tried variable bitrate before either. If I could solve whatever the issue is with vodafone with a vpn or something to stop whatever the traffic issue is, would be great as the upload speed on vodafone is always 20+.

Getting the band 1 antenna is a good idea anyway because i've been back to using my older LOG which is missing one of the bolts and just barely hanging on there and it looks a mess Big Grin
At least it'll provide better performance on the ping side of things until I figure out what to do with these LPDA's. Worst case, If one of the mikrotik R11e4G series supports band 1 3G ( one of the older models since both my LTE6 doesnt work well with latency on any band) I'd be willing to get that for down the field along with the vodafone one . possibly using it to game on and using a LOG in the tree for band 20 as upload for the peak time stream replacement for the vodafone one when the traffic isn't working.

According to ComReg's recent publication, the temporary 4G spectrum expires on the 8th October, so I don't think Three will reprovision any more of its 3G band 1 sites for 4G. However, if for some reason they do with the mast you pick up, then that antenna will work on 4G also. If that happens, you will have just half the available bandwidth (<56Mbps) with the single antenna. In this case you can mount your old horizontal LOG antenna for MIMO.

As I've never livestreamed, I'm not sure where the actual latency setting is. From checking OBS Studio's menus, there is a delay setting in the Advanced section of the left menu. If you enable that, you can try something like 2 to 3 seconds. I'm not sure if that is just to delay the stream or if it allows the server to recover after a latency spike.

I still have the MikroTik R11e-LTE (LTE4) that supports 3G. One limitation with its 3G is that it does not support dual carrier 3G. Three's 3G band 1 masts are dual carrier, so it only gives half the downlink bandwidth on 3G. As 3G only transmits on a single carrier, the upload speed is the same. I haven't heard from the person that wanted to buy it back in March as it was just before the Covid lockdown. If you are interested in swapping the main "LNB" part with mine (should fit a padded envelope or small box), send me a PM. You can use butter knife or a flat blade screwdriver to release the clips of the two arms.

I'm still keeping an eye out for any further Starlink updates as I've no doubt that will get the mobile operators upgrading slow/congested rural masts or risk losing a lot of customers.
Reply
I'll update my post whenever I get that 3G antenna (hopefully tmoro) and i'll try all the stuff with the cables too. If nothing works then yeah I might actually do that since I have barely any options left with regards to my inet Cry I'm also praying for starlink to come here, hopefully they allow other countries to test as well and not just the USA.

Hi, I have set up the MikroTik LHG LTE6 using a virgin SIM, which is operating on the three network, I couldn't seem to get 4g working too well no matter what I did so I only checked 3g, but have still got bands 3 and 20 checked (they should be for 4g? But checking 1 and 8 made no difference)
To begin with I was sometimes getting 20 down and 2 or 3 up which I'd be happy with, but the signal constantly comes and goes, almost in a pattern, any idea why this is? See the vid an pic to see what I mean

Mikrotik https://imgur.com/a/hUsKLQw,

It doesn't matter where I move the dish the same thing happens, there's obviously an issue but I'm no expert so can't work it out, I could do speed tests and get 5 upload on one and then get 14 upload on the next test, it's driving me mental

To me, it looks like it is flicking back and forth between two cells, which could be across two different bands.

Try selecting just one band at a time, e.g. start with band 1 on 3G, then band 8, then band 3 on 4G and finally band 20 on 4G. If no bands are ticked for the chosen network mode, the router enables the lot as if they were all ticked, which explains why it connected in 3G with just the 4G bands 20 and 3 ticked. Try also selecting band 1 only on 4G as some Three 3G band 1 masts are reprovisioned for 4G until the 8th October.

You also check the actual mast it is connected to in the command line. Type the following command:
/interface lte cell-monitor 0

This will show the current band and cell it is connected to. Here you can see if it is flicking back and forth between cell or band #s.

For the dish alignment, 3G band 8 and 4G band 20 are not focused by the dish, so will give a similar signal strength even if the dish is up to around 45 degrees out. Bands 1 and 3 are focused, so if you get a connection with either band 1 or 3 chosen only, the dish needs to be aligned as a few degrees can make a large difference to the RSRP and SINR values.

Thanks, tried this tonight, getting the same spike effect on all bands, only getting about 2 down and 4 up on LTE at best, most of the time not working at all, still getting full bars dropping to none on 3g, I'm not sure how to enter that command because I'm only using the mobile app, I'm getting 12 down on 3g which does all I need it to do, but it's frustrating when you know it could be better, do virgin get the same speeds as three or would three look to throttle their speeds a little?

Was getting this at one stage, the rest of the info was marked on there too under the graph but dropped off the screen as I hit record for some reason

With this issue happening on all bands, this is either looking like a faulty unit or the App is not properly applying the band change to the router.

If you have access to a computer, go into the MikroTik's web interface ( http://192.168.88.1/ ) and try selecting the individual bands there. That web interface has a terminal tab where you can type the above command. I'm unable to tell from the screen recording as it doesn't show the current cell ID or band # that the command line does.

From speed tests I've seen, Virgin Mobile's performance is very similar to Three, so if a phone with a native Three SIM gets around 40Mbps, you can expect to get around 40Mbps with a Virgin Mobile SIM with all else being equal.

I seem to be hitting different cells when I switch from 3g only to 4g only, for some reason the pics I took won't upload to Imgur so I cant link them to here,

These were the cells recorded, one on 3G only, one on LTE (described as evolved 3G)

As you mention the cell # is stable, I think this may be a faulty modem. Generally the only time the signal would fluctuate on a specific cell is if there is something intermittently obstructing the line of sight, such as wind flapping a tree branch in its view.

Just to rule out a firmware bug, I suggest checking the RouterOS and the modem firmware for updates. To update the RouterOS, click the "Check for updates" on the router's main QuickSet screen in the PC browser and choose the version that corresponds with what's installed, e..g 7.x.x if it has let's say 7.0.6. This will take several minutes to update the RouterOS software.

To update the modem firmware, type the following in the command line to check if there's a new version:
/interface lte firmware-upgrade lte1

If the latest has a higher version, type the following to download and install this firmware, which may take up to 10 minutes:
interface lte firmware-upgrade lte1 upgrade=yes

If the signal is still fluctuating, I suggest either contacting the seller or posting this issue on MikroTik's support forum. They may have further suggestions:

Ok, thanks, I have three days left where I could return it to Amazon but will try and contact them first to see what they say, there was an option to update the dish within the phone app and I updated it last week, was having the same issue before the update, haven't checked if there is one available since
