At first I thought my Droid simply couldn't do WiFi, but then I took an international trip where the data plan was simply not an option. To my surprise, EVERY network connected to the internet just fine. That means something about my network isn't Droid friendly. It's been like this for about 6 months.
I can connect to the network, but certain things don't work.
Connecting to and pinging other computers on the network DOES work.
Visiting websites does NOT work.
WeatherBug will NOT update when it must use WiFi.
Dropbox will NOT upload or download files over WiFi.
And again, this is only on one network, the one at my house. The router runs DD-WRT and operates on the B G and N bands. The network name is 'h' and it uses WPA2 security. The ISP is Comcast.
What other things can I do to diagnose the problem?
