I have a Blackberry Curve 8320 service provided by T-mobile. I use a Linksys wireless 350N router for my home network. The issue is: my phone auto connects to the wireless home network but then frequently disengages at will. If I am on a call using the home network and it switches over to the t-mobile network, I drop the call. I have checked my firewalls and everything seems to be in order. any advice?
I would consult tmobile and make sure your Blackberry is configured correctly for this usage. Sounds like it defaults to a GSM signal over the Wifi when it picks it up. There might be something in the actual phone settings to prevent this
Yes, first make sure you have a good wireless signal from the router. Also, have you changed your mobile network settings on your Blackberry? Go to Options>Mobile Network and be sure that "Connection Preference" is set to "Wi-Fi Preferred" or "Wi-Fi only" (while you are at home). I know this definitely helped in my case!
