I have an older 54g Belkin router model. Lately the wireless radio function has been acting up.

The WAN light is constantly blinking (never really caught my eye but i don't think it has always done this, I'm 99% sure it was a solid green instead of blinking at one point.)
and the wireless radio is periodically failing.
Fearing some sort of interference i have changed the channel on the router a few times and i don't see a correlation of the wireless failure and another household appliance (ie: the cordless phone on same freq. or the microwave etc.) Once the wireless fails it doesn't work again until i manually restart the router. The desktop hardwired to the router never has problems and works even when the wireless function fails. Now the connection to the router is still active and i can release and renew the dhcp ip, but for some reason there is a problem with the router transferring packets to my computer (wirelessly) after a certain period, which is never the same length of time.

Is it just a faulty radio function that took a lightning strike? or is this a configuration problem??? Lost here and im tired of giving the router a restart 3 times a day because the wireless funtion decides to stop responding, or sending out packets of info for that matter.
