Ian ping the Pi from the ARMX6 using 192.168.1.90 with no data loss.
I can ping 192.168.1.90 from the W7 with no data loss if the Pi is 
online. With the Pi off line I get data loss.
If I ping the W7 192.168.1.30 from the Pi I get data loss as I do 
pinging the ARMX6 (192.168.1.20). However the data loss is around 20%, 
not 100%.
If I try to set up the WiFi Config app on the Pi it always fails with 
'Failed to enable network in wpa_supplicant configuration' on pressing 
the 'add' key.
My Nexus can see all the computers using Fing and ES file explorer.

Tricky one. Try running something computationally intensive on the Pi 
and ping it from one of the other computers to see if you get any packet 
loss in that direction then. If so the Pi may not be supplying 
sufficient power to drive the Wifi dongle unless it is idle.

Tried that by having a game running while pinging and got 7% to 10%
packet loss.
Tried different dongle with no difference.

My conclusion is the setup is wrong on the router or the Pi or both.

It used to work with the old router. So the Pi hardware works.

It works for W7.

It only doesn't work where you have had to change files or settings.

That tells you where the problem is.
