What could make a Wi-Fi connection/network simply stop every hour or so?

Works absolutely perfect and speedy all other times, but every hour or so data just stops going and everything is down to zero. The connection icon says everything is fine, no errors, but all FTP apps and IE are unable to send and receive data.

I have to go to network connections, disable and re-enable the wireless network connection to get it flowing again.

I hate things like this about wireless, it never just works, always some little niggly thing somewhere deep inside a load of options upsetting the whole thing
