Help. Have MN700 Basestation with a 510 wireless USB on PC downstairs. Initial installation was good and all worked ok. 3 weeks ago, PC w/USB wireless stops working. Reinstalled both sides, but cannot get WEP key to be recognized by basestation. 510 does see basestation since I have changed SSID. Runing XP on PC and ME on basestation PC. Any help or suggestions? Tom BTW, DSL modem is set at PPP, not bridge, basestation is Dynamic on WAN setting. Basestation PC works ok.
