Pretty much all my gear is on the ground floor but I have an ASUS AP upstairs in the lounge connected by cable to the Genius.
If a mobile device is connected via the AP, it can see and access everything on the network.
If a mobile device is connected via the Genius wifi, it can only see other mobile devices and the Genius. Pings to other devices return Destination host unreachable.
All cabled devices can see and access everything.
All devices, no matter how connected, can access the Internet.
Got me puzzled. Can anyone see the 'obvious error' I have made?
TIA.
