Strangely I was able to fix my issue, with an Airave reboot of all things. I started to have intermittent 3G data dropping, texts weren't being sent out. Really frustrating.
I tried to doa PRL and Data Profile update, but I kept getting booted.
Then it dawned on me the only thing I hadn't tried was an Airave reboot. As soon as the thing rebooted the PRL and Data Profile updated no problem, now I'm getting rock solid WiFi, texts are going through no problem, etc.
What I can't understand is how the darn Airave was messing with my WiFi connection??
They're 2 completely different units.
