Just got ATT gigabit here and the WiFi coverage from their device is not great. I grabbed a Google OnHub I had in my closet and plugged it into the ATT box and set it up as an access point, and by default it uses a different subnet, 192.168.86.X, compared to the ATT device's 192.168.1.X. This is mostly fine and I can do just about everything between subnets, including SMB and Plex, but WOL doesn't seem to work. That is, I have an app on my phone (192.168.86.X) to perform WOL and it can no longer wake my desktop (192.168.1.X). It only works if both devices are on one subnet or the other.
Do I need to do something special to allow WOL to work across subnets? Or can I set my OnHub to use the same subnet for itself and its DHCP clients as long as none of it interferes with the addresses being used by the ATT box and its DHCP clients?
Edit: Reading this may actually be due to double NAT. ATT box doesn't have a setting for bridged mode but the OnHub does. Will look into that more.
Edit2: I think I'm just screwed. If I set bridged mode on the OnHub I can no longer specify DNS for my DHCP wireless devices -- ATT box doesn't allow it. So either I don't get WOL or I don't get to specify DNS servers. I want both but I want the latter more. Oh well.
Edit3: I ended up setting the OnHub to bridged mode and bought a Raspberry Pi to handle DHCP/DNS.
