netgear MR814v2 and centrino 3945ABG do not talk

Tried configuring a Toshiba notebook with builtin Centrino 3945ABG to work with an old Netgear 802.11b router (MR814v2). It would not work with 128-bit WEP enabled. It would work if I disabled encryption. Did not find any information about this on Netgear or other support sites. I did upgrade firmware on the router as well as for the wireless device (v10.5.1.57 date July 2, 2006) without any success. A bunch of other cards including a a couple of Dell builtin wireless chipsets worked just fine with this router. I guess it is time to buy a new router, and take advantage of 802.1x security features while I am at it...
