How to set up Tenda Nova mesh for wired backhaul - MW5, MW6, etc.

[jarni]

For the first time set up, connect the WAN port of one node to your ISP router and do not connect any Ethernet cable to the other two.  Turn on the power to all three nodes.  Go through the wizard process in the Tenda App.  You can try them first without bridge mode, which is how the set up wizard configures them after it completes.

After you finish the set up wizard and all three nodes have a solid green light, you can then move the second and third nodes to where you would like them.  Before you connect the Ethernet cable, switch off the power to all three nodes and run the Ethernet cable from the LAN port of the primary to the LAN port of the node you want to use wired backhaul.  Turn on these two nodes and wait for the LEDs on them to go solid green.  Go into the Tenda App, touch the secondary node and it should show a green <---> symbol on the Connection Quality line.  Finally, turn on the third node and it should connect by wireless backhaul.

Hello, this procedure describes first connection with Method 1... does anyone know what is the procedure for Method 2? I am connecting via Method 2...

Yesterday I posted my network scheme - two posts up... Today I started new and fresh install...

I erased app form my android, hard reseted all 6 mw12 nodes (with inserting pin into the hole and holding until they start fast blinking), unplugged all nodes from all cables. Then I gathered them all in one room and started the procedure. Inserted ethernet cable from router to wan port in prime node, and then powered them all up. All 6 connected with excellent wifi signal. Then I turned them all off and started relocating the nodes to their positions, putting ethernet cable from prime node to switch, putting ethernet cables to all relocated nodes into LAN1 port. Then I turned them on. Turned the Bridge mode on. Fast roaming is set to ON. Capacity oriented mede to OFF. Smar assistant OFF.
All the nodes have the same latest firmware.

Again very bad and erratic speeds on most wired nodes...

All the wired nodes have signal <...> but the speeds are very different... prime node 480MBps, on secondary nodes from 20 MBps to 80 Mbps...

Is there someone who can try helping me... what can be wrong here? 

There are some other settings that I do not know how to set... 

Connection type is supposed to be set to Bridge?
