Think about sharing the network details. Last time I found the router was out of date.
It happens. The first time I encountered this issue was the Vista beam of death. AKA "Broadcast Flag", many routers would lock up or reboot when a Vista machine was near.
Every time I connect to my home network with iPhone 4 my whole network
stops working. Windows 7 is not reporting any problems with connection,
nor is my router. I have cable connection with my PC and wireless with
my laptop, they both just stop working without any visible reason. Even
the iphone i connect with wont work, but of course it says its connected
and everything is ok.
I tought it was an iOS 5 problem, so I reinstalled it. It worked for an
hour then its all back again. I even tried sharing my PC connection so
that my iPhone is connected to PC and not directly to router. But that
produced the same results.
My roomate's iphone 3gs with iOS5 works normally.
Any ideas? Thnx.
