Where does the 7925G and 8821G phones get their Wlan Driver and Wlan Firmware?

[jamize]

We are having issues with our CP-7925G and CP-8821G wireless phones dropping calls and we have been asked by our networking group where the phones get their Wlan Driver and Wlan Firmware.  I know the phones firmware is obtained via the TFTP server on the Call Manager.  Does anyone know where the Wlan Driver and Wlan Firmware are obtained for the wireless phones?

We are running CUCM 11.5.

Thanks,

Jeff

Dropped calls?

If the wireless is Cisco, what firmware is the controller running on?
