I am currently in the process of migrating our AP's to LWAPP and utilizing WCS. During the "migration" I noticed that a few of our client laptops are unable to connect to the AP's. After researching this I found out that our WEP keys for two seperate VLANs are identical. Additionally, they also both use key index=1.
At first I was configuring the WLANs on our WISMs and didn't see the error message, but when I went back through WCS I noticed the problem.
I also have a third WLAN with a unique WEP key, but it also uses key index=1 and after testing a few clients I receive the same error message and no clients are able to connect to the LWAPP AP's.
Has anyone seen this before? Is there a "painless" work around? Or, has anyone worked through a similar migration?
