Hi Guys,
For anyone that has an LHGG LTE6 or possibly (LHG LTE6) and don't get decent speeds.
The latest couple of ROS and modem firmware releases seem to have improved performance greatly (for me at least on the EIR network).
Up until today I was using Router OS v7.1rc5 with Modem f/w V028 Which gave a pretty decent 45Mb/s down and 30Mb/s up. (Single band 3).(CA didn't work well with these firmware versions)
Previously Modem f/w V027 and the stable channel of ROS was only giving me 35Mb/s down and 30Mb/s up (band 3 + b20 CA)
Today I upgraded the LTE Modem to V029, (still using Router OS v7.1rc5) and straight away my download speed went up to 70Mb/s and same 30Mb/s upload.
I have never seen those speeds here with the LHGG LTE6.
Carrier aggregation now also work properly again.
Worth a try if you have one of these units.

That's great they finally fixed the carrier aggregation, although they sure took a long time. I wonder if it also fixes the intermittent latency spikes that a few also reported.
I still have the older LHG LTE4 somewhere in the loft, which is not CA capable.

I have two of them I no longer use, they were horrible performance wise and completely unusable for gaming. Bought the second one to rule out a hardware issue but they both had the same problems... So many issues, I might hook them up and update them and sell them both. What would you sell them for do you think?

I was unable to find any sold listings for the lte6 model and just a few used listings from Latvian sellers with a massive delivery charge. As it's selling for about €150 new (on EuroDK), I suggest listing them priced a little lower, especially as they are in like-new condition. If there are no offers, you can drop the price by €10 every week or two.
Another option would be to try selling them off locally, especially if you know anyone considering getting 4G broadband or an antenna.

I replaced the modem on my LTE6 with an EM12-G and now have CA with b1, b3 and b28, my speed has increased to 120 Mbit/s down and 40 Mbit/s up. Well worth the upgrade.
Info here

Multiple shops on AliExpress have the EM12-G modems

I noticed theres 5G modules in there under modification options , does that mean I could change the one on the chateau 5G to one that potentially might work with the N3 here?

Potentially.
But doesnt the default RM502Q-AE already work with N3, looking at https://i.mt.lv/cdn/product_files/Chatea...210344.pdf
Mine came with the RM502Q-AE 8 antenna version

The issue with mine is complicated, the N3/N78 bands won't hold the connection because of distance from the cell tower on the chateau 5G (X55 snapdragon modem) but an A22 5G phone with a mediatek dimensity 700 modem works fine and can hold both these bands from my home with no disconnection loop - 200-300 Mbps download and 50 up with the mobile.
So Seán found this https://www.aliexpress.com/item/1005004444946323.html
which is based on the same modem thats inside the A22 , if I were able to put this into the chateau 5G / if there was a way to get it to work, would be amazing but I have no idea how.

Yeah unfortunately that module is X55 based , which is the exact modem that has the problem I described.

Just upgraded a stock modem on LHG LTE6 to V034 with rOS 7.6rc3, cant seem to get CA to work. Is this a known issue or just maybe my config wrong?
NOTE: old speeds were 12mbps, now circa 35mbps. a nice increase just from firmware upgrade. would love CA to work to squeeze more. This is on Three network.

The Modem in the LHG LTE6 will only CA with B1+B20 or B3+B20 . It doesn't support B1+B3 CA .
I have since changed out the modem for a Quectel em12-g. Massive improvement. I can now CA B28+B1+B3 . I also changed from Eir to three hero sim and get a much better connection in my location

Yes have LTE band 1 3 and 20 as options, doesnt CA. i had CA on ros6 + modem F/w 025. band 20 available in the area, but didnt work. Tried a downgrade to 7.6 and didnt work. tried in another location, still didnt CA on either 1+20 or 3+20.
The hero prob offers you the cheapest internet in the market. They now over a candy bar sim for 4euro ex vat, all you can eat data if your okay with the topups each month like what your doing with the hero. Should give that a try? Also Im still waiting to see what will happen with band 28....

The r11e-lte6 is a very poor modem:
https://i.mt.lv/cdn/product_files/R11e-LTE6_201050.pdf
I have a Quectel EM12G in mine, though if you do not want a cat12 modem, MikroTik now offer the SXT LTE US with the EP06-A: https://mikrotik.com/product/sxt_lte6_kit_us
The European equivalent is the EP06-E which can be found for not much on AliExpress: https://www.aliexpress.com/item/1005003264866461.html
And it supports B28:
Frequency Bands
LTE-FDD B1/B3/B5/B7/B8/B20/B28
LTE-TDD B38/B40/B41
2 × CA: B1+B1/B5/B8/B20/B28;B3+B3/B5/B7/B8/B20/B28;
B7+B5/B7/B8/B20/B28;B20; B38+B38; B40+B40; B41+B41

B7+B5/B7/B8/B20/B28;B20; B38+B38; B40+B40; B41+B41 I might get the EP06-E for testing, thanks for the info. It's the B28 that piques my interest in this over the stock modem in LHG6.
is this the EM12G you have? https://www.aliexpress.com/item/4001264954771.html
You rekon i can bung them into a LHG dish?

That's the EM12G I have, currently in an LHG LTE6.
I did a required parts list over here:
https://www.ispreview.co.uk/talk/threads...ems.38196/
EM12G
M.2 Key B to Mini PCiE Adapter
IPX4 to IPX1 cables
@Waveguide has also carried out the upgrade.

I decided to order the EP06-E for testing as I have an LHG LTE (cat 4) model and am curious to see how well it performs on bands 1 and 3 during peak time here. I'm too far from the mast for it to connect on bands 1 or 3 as the primary band, so can only use it as CA (band 20 as primary), which my LHG can't do. In fact, the distant mast does not seem to allow any 4G cat 4 device to connect at all from my >50km distance, not even on band 20.
If the LHG with EP06-E performs better than my Iskra P-58's with the Chateau 5G locked to 4G 20+1 or 20+3 during peak time (to test like for like comparison) and gives a similar upload on band 20, I might consider getting the LHG LTE18 kit.

I'd be interested to see how it performs especially the b28 support.

The EP06-E arrived, taking exactly 3 weeks from the date of ordering on AliExpress. Installing it however was more tedious than I anticipated, but at least it works.
The outside cover of the LHG is clipped on, requiring a blunt flat metal object (e.g. butter knife) to release the clips. While the PCIe board is easy to access without anything in the way, there's a catch - They covered the U.fl antenna connections in hot melt glue.
I removed the PCB which requires a T9 Torx screwdriver and slowly melted the glue using a mini heat gun from a distance and holding an old credit card over the modem/circuitry to protect from the heat. This took about 30 minutes as I removed the softened glue bit by bit to avoid damaging the U.fl leads. Finally, it was just a matter of removing the two screws holding the modem in place and swapping the PCIe boards.
Upon first boot up, I got a little concerned with the modem not showing up, but with it running an old router OS v7.1, I manually updated it and the modem appeared and connected straight away after the update. For testing, I used a Three prepay phone SIM, the same network as my main broadband SIM
I mounted the LHG on a camera tripod and placed it outside the house facing the same direction as the Iskra P-58's mounted on the gable. This was just for a quick test run I did in the morning as I will do further testing when I get a chance on a dry calm day. It's typically wet and windy here, being near the Atlantic coast.
One thing's for sure, it's a big improvement over the R11e-LTE at least based on my brief testing, unless the R11e-LTE was faulty. The RSRP readings are appear to be 3dB to 4dB more than the R11e-LTE both on the lower and upper bands. Compared to the Iskra P-58's + 7.5m leads (mounted on the gable), the LHG manages to beat it by around 10dBi on band 1, whereas the Iskra's are around 6dB stronger on band 20. I will do further testing another day when I get a chance to test the LHG high up temporarily to do a like for like comparison.
As mentioned earlier, I can only connect to band 20 as the primary band due to the >50km mast distance across Donegal Bay, so the only way I can test bands 1 and 3 is with carrier aggregation, i.e. with cell monitor, which lacks the SINR read-out for aggregated bands.
LHG with EP06-E:
Chateau 5G with Iskra P-58 + 7.5m leads:
Speed tests on the LHG - Bands 20+1 CA, Bands 20+3 CA and Band 20 on its own:
For 3CA , this calculates (removing the second band 20 count) as 73 + 81 - 9 = ~145Mbps.
3CA (same EARFCNs) speed test on the Chateau 5G with Iskra P-58:
The download speeds certainly look promising with the LHG. The upload speed however is much lower than what I would like to consider getting the LHGG LTE18.
When I get a chance on a dry calm day, I will try some further tests including on the Eir network that uses band 28 in my area.
