Wifi Was Working But Not Now 1.1.1

[dude859]

Hi - I have this strange problem - my iphone was working perfectly with my belkin54g router. Just yesterday it seems that I lost connection on my router so I had to reboot the router - the router is now working fine as I can use it with my laptop and desktop pc. When I try to connect via the iphone I get the message that it cannot open safari because it cant find the server (hence no web application will work) I checked to see if my iphone was connecting to my router by putting in the ip address of my router ie 192.168.2.1 - this worked and this allowed me to see my router settings so hence I believe that the wifi is working on my iphone - I then reset my iphone settings and inputed my password - it shows my router on iphone (belkin54g) but yet again I cannot open any browser etc. The iphone version Im using is 1.1.1 and is unlocked as Im based in Ireland. Can anyone please help me please as Im quite desperate to get safari and all my web applications back up working again. Many thanks Ron
