To get in to the router admin, on your PC go to
http://192.168.2.1 in a web browser, or use the Belkin Router Manager software if it's installed. From there you should be able to check the settings and compare them to what's on your laptop.
Did you have to change anything on your iPhone or has it continued to work ok?
Thanks - really stupid question but where are the settings on my laptop? I didn't change anything on my iphone, just connected fine as normal
Oh dear and
