I've been experiencing an odd issue with the Captivate and Wifi. I'm right next to my router, signal at full force, all bars showing on the phone, and I get the "page not available screen." At first I thought the problem was with the sites, but everything works fine on 3G. I tried multiple websites, and I've been getting mixed results. This phone is new, I just exchanged my last phone for it a few days ago, and my grace period ends tomorrow. Does this sound like an issue that is the fault of the phone hardware, software, or am I just over reacting? I'm concerned because tomorrow is the last day I can exchange it, and I want to make sure that there is nothing wrong with the wifi radio.
