    Does anyone else hear a high pitched whine emitting from their WRT54G routers? Does it happen occasionally, all the time, or not at all? I'm sitting next to it and can definitely hear it. It's like a faint dog whistle.

    I don't know if I should try to exchange the unit.... might be too late since I just updated with the HyperWRT firmware; or just snuff out the noise by putting it behind my cabinet. Or hit it or what.

    Was it whining befor the upgrade?

    I reuploaded linksys' latest official firmware and it still had a high pitched ring. I saw on another forum that it might be the inductor coil inside that is vibrating and causing the noise. And that spraying some pbc lacquer on the coil might help.

    But I figured I just bought the thing and don't want to void my warranty already by opening up the cover. So today I exchanged it for another unit, same model. The new one is very quiet so far. I'll try the spray thing if it ever starts making some noise in the future.
