I've had my X since day one and have had zero issues. I set up Wi-Fi through my (Verizon) ActionTec MI424-WR router and everything worked well.
Just last night I noticed that I could no longer use Wi-Fi at home. The home router shows up in the 'out of range' group. I 'forgot' the router and then re-added, including the correct WEP key. (Tried it several times ...) The X tries to connect but ultimately quits. All the other home Wi-Fi devices (including a BB and my wife's dismal Devour) have no issues connecting so it appears nothing has changed from the router side. I was at Starbucks this P.M. and easily connected through their AT&T wireless. I removed a few apps I recently added but nothing changed. Oh, I've rebooted and removed the battery as well. Pretty strange.
Thoughts?
