For some reason, my i760 stopped connecting to my Linksys router the other day. I tried a soft reset (i760), disabling MAC addressing and encryption on the router, rebooting the router, but nothing worked. My i760, however, did connect to at least 1 open WiFi router at a coffee shop. Then I tried updating the phone using *228 and voila! I'm back in business. I thought I'd share this experience in case it has happened to someone else.
