WiFi works, but disconnects when idle
I've got an jailbreaked/unlocked 8GB iPhone with firmware 1.1.1 and everything works pretty fine, but a little problem is annoying me.
When I switch on the iPhone I have to search my WiFi network at home, and it finds it and connects to it without any problem. But after the auto-lock is activated (i've got it configured to run after 3 min) WiFi signal dissapears when I push the home button or the phone comes to life because of a call or a calendar event. So I've got to search and connect to it again and again.
I've read maybe its a problem of Summerboard - not sure about this - and installed the JohnTool, but it seems that hasn't made any difference.
I'd like to have my iphone connected all the time to the network... why it dissapears?
