I hate to say it, but I've seen this before with LinkSys adapters. Consumer-grade adapters just aren't as high of quality as enterprise cards like Cisco adapters.

The best thing you can do is perform a site survey, setting all APs to about 30mW. I believe that's as strong as the LinkSys cards broadcast. You might just have coverage holes that the Cisco cards were able to overcome.

I hope that helps,

Thank's for you answer.

Do you know another USB-client adapter, which is cisco ccx compatible?

I don't know of any enterprise-grade USB cards. It's unfortunate that Cisco doesn't make USB cards.

I'll also add that if you're going to use USB clients, you might as well use the internal wireless cards in the laptops since they're likely on the same level of quality. Heck, the internal cards can sometimes be better, as some laptops have antennas that wrap around the screens, boosting their signal.
