I thought my iPhone had bit the dust

The last couple of days my iPhone has been locking up to the point where I would have to hard reset it every 10 minutes.  I’ve been planning on going to the Apple store but I’ve been working at home all week.

 Being a software dork, I was beginning to notice patterns with the phone. It did not work well at home, but if I went down to Starbucks, to the movies or hockey my iphone would work!  

What is the one thing that is different about being at home beside AT&T service sucking and having 2 bars if I’m lucky, was that I have wifi at home.   I turned off the wifi on the iphone and guess what, it started working again!

WTF? Why would that be?  I then realized that I had changed the wifi keys on the wireless routers at the home because my teenage daughter has been grounded from the internet.  I thought all was good because I had changed the passwords on the computers but she was caught using her PSP and Wii to browse the net.  Instead of worrying about every wifi enabled device in the house (which is plenty), I changed the keys.

What would you know,  the iPhone has a bug if you change the key of an existing router without reseting the key on the phone. It would be interesting to see if others have had the same problem.
