Re: Wifi Network Scanning Problem
In most cases unless the phone is defective the issue is the security on the router or the info on the phone. I don't know of any OS issues or basic function issues with BB.
One thing you might try is interaction with an APP you added to the phone. Some have been know to cause various issues and even block connectivity.
Do a backup of the phone using Desktop Manager ( free from blackberry) and delete apps one at a time to see if it works. Yes it will take time but it will at least show you if the phone has a physical issue with the radios.
