I just got my n810, so far so good. Still playing around with it, and need to get a bigger card for it.
I have a snag with my wireless setup, however.
I have two access points in my house- and older Apple "airport express", which supports B & G, and an apple "Time Capsule", which supports N, B, and G (the time capsule is basically an airport extreme with a harddrive built in).
When I connect to the express, all works fine. When I connect to the TimeCapsule, it works for a short time, then stops. The little indicator at the top shows that I am "connected", with reasonable signal, but I can't get anywhere (no http, no ping, etc).
Is there something that I can try to resolve this?
