I have raised a ticket for this via the online system but the 'within five days' to respond is a bit off-putting.

Basically, there is no connection between the wireless and ethernet connections. Ethernet can't ping wireless and vice versa. Using Fing on a wifi connected device it only shows the Genius and the device being used. 

I have another AP wired into the Genius and it sees all devices no problem.

I have had this before but a couple of repowers fixed it, but not now. I also tried a hardware reset and that ended up with the Internet LED on but still no outside connection and no phone. A couple of repowers and this was fixed but still no wireless/ethernet connections. 

Do I need a new router or can this be fixed?
