I'm having issues with my wireless router (Linksys WRT300N). All the port lights (despite having only one cable plugged in) as well as the internet light are brightly lit, but the power light is dim. There is no connection being made between the router and my desktop (Windows XP), and I'm getting a "Network cable unplugged" network error message. Tried unplugging/replugging and resetting to no avail. Also tried different power adapters with no luck.
Connecting the desktop directly to the DSL modem works fine.
I recall this happening once before, but I don't remember how I rectified it - any insight that could be provided is welcome.
