Hello all. This is my first post here so be gentle. (I've been a long-time lurker.)

My 32GB WiFi TP seems to suddenly be having a problem staying connected to the internet. It says it is connected but all applications give a "Error: Unable to resolve host." error. Turning wifi off and on seems to fix the problem temporarily... but it quickly happens again (within 10 minutes). I have manually set the IP address, DNS (to several different DNS's), etc. I have reset my router several times. I have doctored the TP 3 times.

I have tested it on the open wifi where I work and it seems to stay connected. However, any secure network (WEP/WPA/WPA2) seems to result in a constantly lost connection.

Any suggestions?
