I have read some of this forum and not found an exact answer so need to ask this question.

I have a cable connection plugged into a belkin 54g router. We have 2 laptops and 1 PC which has a wireless usb adaptor. All three computers continually lose the wireless internet connection and either pick it up again or we have to disable and enable in network connections wireless. I have soft and hard reset the belkin router many times and reprogrammed it a few. The problem does not happen at the same time everyday and often can be fine all morning and start being a problem in the afternoon or at night. 

Could the problem not be the belkin router but the internet connection coming from TelstraClear?

I have heard others complain that their Telstra cable connection drops out at peak times.

I don't want to buy a new wireless router if its not my wireless router at fault.
