I'm using a Versalink D90-327W30-06 Wireless Router. The only setting I changed is the Wireless > Configure Wireless > Wireless Security > Disabled. If the security is WEP, my iPhone cannot access wifi.

For some odd reason everytime I would browse wifi on my iPhone, it would go back to edge after a few minutes and then switch back to wifi. Ironically, it manages to interrupt my internet connection on my PC too. In other words, if I'm playing video games online, I would turn off my iphone wifi.

Any tips?
