I can connect to my LAN, but with local access only. I've been to the mfg's forums and tried their fixes, driver updates, and manual setups- no joy so I've reset to auto defaults. This laptop connects to several other routers wi-fi without problems. The WNDR3700 solved all my previous router problems, was truly plug and play, and may have cured me athsma as well. The event logs show a time-out during the semaphore portion of the log-in.
