So I have a Linksys WRT300N and for some reason today the wireless stopped broadcasting. I went and checked all the settings, nothing had changed, SSID was still enabled. I've turned it on and off a couple times to no avail.
Google has found me similar problems, but no solutions. Linksys chat support is, well...abysmal. Was hoping the fine folks here had some ideas?
It looks like I'm buying a new router though. I have had this thing for like 4-5 years so it might just be its time.
Try resetting the router -- reset switch is usually behind a pinhole on the same surface as the networking sockets. Then recheck router settings -- particularly that wireless is enabled and that wireless mode is correct for your wireless adapter.
