I connected my blackberry (with OS 7.1) to my home wifi network and BB Browser, Opera and instant messenger IM+ work without any problem. But every time I go out and return home, the phone will give error for Opera and IM+, although BB Browser works without any problem and device says it is connected to wifi. I have to pull the battery and restart the phone then it will connect automatically to Opera and IM+ and they will work without any problem. I don't have any mobile network service package from Rogers and use UMA / wifi to connect to internet and for instant messaging. Same thing happens when I connect to office Wifi. It works fine, first time i connect with it, then when I go out of office and come back, device wont connect to the Opera and IM+ (although BB browser works and the wifi connection is there) until I do a battery pull.
I have tried deleting the wifi profiles, followed by battery pull, then recreating the wifi profile, then battery pull. But the problem seem to persist. I have also wiped and reinstalled the OS 7.1, but that did not solove the problem either. Any insight and solution to this problem?
