We have a Cisco Aironet 1200 series, I enabled WEP Key and it worx fine. However I wat only 8 devices (MAC Addresses) to be able to connect to this device. ie WEP key is readable via Windows 7 etc thus users are fiddling on the WLAN. I want to lock it down to MAC Addresses only if I can. How do I do it.? I use the GUI via IE8. Device setup as AP with static IP.
