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

[jarni]

I suggest try a process of elimination just in case one node is faulty and causing this:

1. Turn off all the nodes apart from the main one labelled 'C1' in the picture. 
   
2. Turn on the node labelled 'C2'.
   
3. After this node finishes booting, toggle your phone's Wi-Fi off and on to ensure it is connected to it (and not a further away node) and run a speed test. 
   
4. If the speed test is similar to the primary node, repeat steps 2 and 3 for the next node, e.g. C3, then C4.
   
5. If the speed drops way down, turn this node off and check that the speeds are still fine on the other nodes before turning on the next node.
   

The other settings mentioned above are fine, i.e. Bridge Mode On, Fast Roaming On and Capacity Oriented Mode Off.

I tried all your suggestions with no success... , but then all of a sudden, the mash started to deliver some serious speeds (200-400Mbps)... I do not understand what happened that made it start working, but now the speeds are awesome!  
Thank you for suggestions!
