Sounds like the transmitter is failing. Warranty? Use it.
My Linksys WRT54GC (version2) model router frequently stops wireless broadcasting and I have to unplug and replug the power cable to connect again.
After some time, it again suddenly stops wireless broadcast until it's repowered.
I've been having this problem for over 2 weeks now and tried the latest firmware upgrade and resetted the router for countless times but couldn't solve the problem.
Anyone, has experience in this issue, has any reccomendation ?
