Bionic unable to connect to 4G since ICS upgrade
I upgraded my Droid Bionic to ICS 4.0 at the end of this last year and since then I have been unable to connect to 4G networks when in a known 4G area. My son upgraded his phone recently and connects to 4G no problem, while I'm at 3G. Also when connecting to our home network, he connects at the faster of the two modes, while my phone doesn't even see the faster speed. Is there a setting somewhere on the phone that I don't know about? The Network Mode is set to LTE/CDMA, but is greyed out so it cannot be changed. Before I upgraded, I was able to connect to 4G and the faster home network mode with no problems. I have tried several different things suggested by members on other forums such as getting a new SIM card (done); Full reboot (done); Clearing the cache (done); etc. I got everything else on the phone to work except for 4G and the faster WiFi... Any help would be greatly appreciated. The guy at the VZW store said if it was still under warranty, he would have replaced it. A couple of screen shots below showing the greyed out settings. ANd I did look at the earlier post about 4G connectivity and that isn't the issue for me. Don't have the 3G/4G switch. Thanks!
