I have a Dell Inspiron 8200 with internal ethernet and I have added a Dell Truemobile 1150 wifi card. I got this card working under RedHat 9 and it continued to work through upgrades to FC1 and FC2. I recently did a clean install of FC2 and now I can't get it to work. This card uses the orinoco_cs driver. In the FC2 Network Configuration tool it is identified as a Intersil PRISM2 11 Mbps Wireless Adapter. I don't use DHCP. After I go through the set-up process and save the configuration and try to activate the card I get the following message: Error for wireless request "Set Encode" (8B2A) : SET failed on device eth1 ; invalid argument. Does anyone have any ideas? I am using the latest kernel: 2.6.9-1.3_FC2. I have the same problem when using the previous kernel: 2.6.5-1.358. I've gone so far as to see if commenting out 'alias eth1 orinoco_cs' in modprobe.conf would help. No go. I've also noticed that upon rebooting a second copy of eth1: eth1Copy0 is added in the Network Configuration tool and both copies of eth1 are shown as 'Active' even though I have set 'ONBOOT=no' in ifcfg-eth1. After every little tweak I still get the error message above everytime I try ifup eth1. Any help would be appreciated. Thanks. Curt Goff
