I'm new to this site and new to the iPhone. I switched to the 3G from the Blackberry and I love it. The thing is that I keep losing wifi signal in my house. It will be connected and then out of the blue I'll totally lose my signal. I thought my wifi signal was dropping, but my computer and my wife's Blackberry are still connected to the wifi. I end up having to turn the power off and when it comes back on, it's perfectly fine. My wireless router is a Linksys WRT54G2 V1. Any suggestions would be appreciated.
