Cannot get my new iPhone 4 to connect to my home network. All other 3 iPhones logging on without issue plus windows laptops and 2 Macbooks. I have even opened up my network briefly to assist but to no avail. Anybody else with issues??
Well what happens when you try to connect?
What configuration is your wireless network?
Is it B,G,N or some combination of that? What frequency is it set to? 2.4 or 5ghz? What type of encryption do you have turned on? What router do you have?
Do you by chance have your router limited to only X number of DHCP addresses?
Many people do this as a security move -- only allow from 192.68.1.2 to 192.168.1.10, for example. Maybe you have just reached the device limit you've set up?
