Mine just did this. It sat in a drawer for months, and the last time I used it it worked fine. Now it connects, but traffic doesn't seem to go anywhere. What's more bizarre is I get errors if I try to connect to a different access point.

Unfortunately, I didn't install simple tools like 'ping' so I'm clueless as to why it's failing to bring me any joy.

Any ideas? (I popped the battery but nada.) My 770s battery is so dead that I think it needs to drink a bit of juice before it decides to boot.

*Edit: The 770 came up with the same failure and it hasn't been updated in yeaaars. Bizarre!!! I just ran sudo gainroot and giggled because that's how we used to have to do it. No joy on pinging anything, even the router. ifconfig reports I have a valid IP of 192.168.1.6... Gonna reboot the router and check back in.
