Wi-Fi stops working even though iPhone 4 says its connected to wifi

Hi im having an annoying issue with my iphone 4. The wifi seems to randomly stop working even though it says its connected it just wont load from the web. I can usually get it to work for 10 mins or so by turing airplane mode on and off but then the problem reoccurs. SOmetimes it will go for days without this happening then wont work the whole day.. seems very odd

can anyone help???

iPhone 4, iOS 4

Read through this document for some trouble-shooting information: http://support.apple.com/kb/TS1398

If this problem only occurs on a particular network, say your home network, you could be having problems with your wireless router (check for router firmware update, power off and restart router) or you could have interference with other nearby networks (change router channel, etc.). Your problem could also be unrelated to your equipment and be due to difficulties in your ISP network. You could check with their support people.

If this problem occurs on all networks then you may have a problem with your iphone hardware.

thanks for your reply

It says on that page i should "Disable 40MHz in the 2.4GHz settings on the Wi-Fi router. Mac computers, iPhone, and iPod touch do not support this mode. Disabling it may reduce interference issues."

How would i do that? I can't seem to find a relevant option on my netgear CGD24N

Not sure I buy that. My 4 stops working on any wifi network. Turn off the wifi and restart and its good for 10 minutes. Also my Ipod wifi works just fine.
