Has anyone found a workaround for this? I disabled my security and it still wouldn't connect so I suspect it might just be a Belkin issue.
A little browsing brought up this from J.Joshua on the Apple support site, I tried it with no success though. Really hacked off.
"I was able to make my iphone work on my home wirless connection by choosing from the main screen
"settings" then "Wi-fi" then under "Choose a Network" I selected my home network (Belkin) (little blue arrow at the end) then under "IP Address" I chose the "static" button clicked on the "DNS" numbers and entered the the DNS addresses of my router as show on the summary page when I logged on to my router from my home computer. As for how to log on to your router and find your DNS addresses refer to your router documentation. I tried many of the other solutions and this is so far the only way I could get a connection to actually work. It would always show the strong network signal on my phone but would not be able to connect to the internet and find the server. Like some others who have posted, until this solution I was able to borrow a connection from my neighbor with no problems but his router was a linksys."
