I just recieved new 7921 phones. I cannot get them to pick up a dhcp address
I keep getting DHCP "Timeout's" and " Configuring IP" .
The ould 7921's and the new 7925's work just fine. I have tried removing and
reconfiguring the WLAN and Interface on the Controllers. I even removed and reconfigured
the DHCP scope in Infoblox. I am at a lost. Any ideas?
Excuse the basic questions, but have you ensured there are free addresses in the DHCP scope? Are the other working 7921/5's in the same WLAN? If this is a new WLAN, are "ip helpers" setup on the L3 interface sitting on the switch/router if your Infoblox appliance is in another subnet?

Try resetting your phone to factory defaults.
Alternatively, browse to the phone's WLAN settings and you will find an option to "release dhcp." Set this option to 'yes' and exit/save changes. (recalling from memory; these may not be the exact steps.)
I've noticed address stickiness with dhcp config in the 7921 before.
