We are currently using a DOS based PC that runs only a 5250 emulator. We connect to the network via a Cisco 350 card on a wide open wireless network. We have successfully set one of these units up to run of WEP side of our wireless. But all other units we cannot get to connect. We have tried loading all the different firmwares for the 350 card. All of the 4.x firmwares load fine and sets WEP key but won't connect to network. When we load the 5.x versions of the firmware, we get a Error Accessing Card: 8007 error when loading WEP key. We are wondering how to be able to get around this 8007 error, to be able to successfully try to connect with the newest firmware of the 350 card. Any thoughts?
