Cisco Air AP

Hello Experts,

I am no cisco guy with very limited skill sets in cisco.  We have move a network off of vlans and just to a classic network setup.  On one of the vlans was 12 Cisco Air-AP1231G-A-K9 units.  We thought going in and changing the I.P. addresses, default gateway and removing vlan settings on each access point would be the best solution, but we where wrong.  4 of the 12 work after resetting all but the I.P. address and configuring them our self's.  The most common problem we have with the other 8 is they will broadcast the ssid but when you connect you get "limited access" or a continuous "obtaining ip address" on mobile devices.

This is the config file from one of the AP with the problem stated above.
