Try using wifi on another device.Also try following steps:
1)Ping lan ip of tenda (it should be equal to your gateway given by DHCP)
2)Ping lan ip of thomson (it is gateway given by DHCP to Tenda)
3)ping 8.8.8.8
I got it to work!
i had NetCutter running by mistake and the device that i was testing the wifi on had the internet disconnected lol.
Everything working now, i put it as DHCP, and the pool list is between 1.100-1.200 and i put all the devices within that ip range with a speed bandwith of 30-50kbyte/s, and its working flawlessly.
