I've just added the Linksys WRT120N wireless router to my list of fail. Even after trying different firmware, internet access was noticeably slower than through a direct connection, connections dropped, settings didn't stick, it couldn't be pinged externally or internally (with or without any security), it erroneously displayed the external IP, randomly rebooted, etc, etc. Configuring it remotely also refused to work, leaving me to do it through Remote Assistance, so it's being returned and replaced with a Linksys WRT54GL.
