We have two different wireless setups each at different locations. At one location we have Cisco Aironet 1200 series AP's secured using WPA2 and AES. At the other loaction we have some old Enterasys AP's using MAC filtering in AD. At both locations there are people freely connecting to the access points and pulling an IP address via DHCP. I want to know if anyone else has had or is having the same issues and what was done/being done to resolve it?
