Hi, I cannot associate my Aironet 350 802.1b PCMCIA WLAN adaptor with my WAG54G. Here is my configuration: Client: Windows XP Professional SP2 with all post-SP2 security patches installed Using Wireless Zero Configuration (tried disabling WZC, and using bundled Cisco utility to associate, troubleshooting reports that client is disassociated by AP, statistics page reports loads of PLCP CRC and MAC CRC errors) Cisco Aironet Client Adapter Installation Wizard version 1.5 802.11a/b Radio Firmware 5.60.08 Windows NDIS Driver 8.6/3.9 Aironet Client Utility (ACU) 6.4 Aironet Client Monitor (ACM) 2.4. AP - Gateway: WAG54G-EU V.2 Firmware: 1.0.19 Wireless mode: Mixed (B-ONLY tried as well) Wireless Channel: 11 (1 to 13 tried) Wireless Security: Open, no encryption (for the time being!) MAC filter applied (including that of Aironet 350) I can associate with all other vendors' wireless ADSL gateways belonging to my neighbors without a problem, i.e., SpeedStream, US Robotics, Zoom, etc. I have two other notebooks, one has a Linksys Wireless-G notebook adapter (WPC54G,) the other has built-in 802.1g, and they don't have any problems with the WAG54G, either. And the Wireless-G Notebook adapter works fine on the problem notebook, so it must be something specific to Aironet 350 AND WAG54G. It's very strange that the only gateway a Cisco WLAN adapter cannot associate with is Linksys, which is owned by Cisco!
