I have the original Droid A855. I have Comcast's Arris TG862G/CT wireless router/modem. My droid will not connect to the WiFi and I'm fairly certain that the problem lies with the phone since my computer connects to the WiFi no problem.
I will enter in all the correct names and passwords for the WiFi network, the phone will attempt to 'authenticate,' and then the phone tells me that the network is 'Disabled, secured with WPA/WPA2 PSK'
The strength of the network is 'excellent.'
I have also tried adding the network to the phone manually with the same results.
