I continually experience reboots that return to the on state but have no radio connectivity (wifi or cell). If I keep my wifi disabled my droid will run fine for weeks. The longest that it has lasted with wifi enabled is 2 days. The issue might be the switching between the 2 wireless networks that I use. An unsecured g network at work (external internet access only) and my home g network with WPA/WPA2 PSK security. Thoughts? Others with same experience?
