Netgear Wireless router help

Hi.

I have this netgear WGR611 wireless router for some months now. I'll get straight to it. At random times, the router's wireless signal shuts off as well as the internet signal, and then after a few seconds to a minute it comes back. I'm not connecting this wireless as it is going through the RJ45 cables. I have turned off Wireless Zero Configuration in services.msc. Anything else I can do to get this fixed?

This is on my desktop computer which is not connected wirelessly again. Thanks.
