Good day,
I recently got a 8900; it was locked T-Mobile but I got it unlocked and now using it with Digicel.
When I try to connect to Wifi, I get nothing and the phone sometime restarts. I upgraded to 5.0....461 and the restarting stopped but the Wifi still does not connect.
BTW, wireless network is open but I still dont even get the options or the available networks.
The first place to check is the built in Wifi Diagnostics.
Connections / Wifi Options. Menu / Wifi Diagnostics.
The first section is your Wifi connection. If everthing is correct, you will see two green check marks and a Successful connections status message. If not, note the error message for troubleshooting.
