I have this phone using the latest device pack and Call Manager 18.104.22.16800-11.
The phone has firmware: sip9971.9-0-2.
I'm having problems trying to get wireless to work on the device. I've enabled it in the call manager under that particular device. I've also set it to "on" on the phone itself and also set WLAN Sign in Access to "on". I do not see the wireless signal strength symbol come on though. I've set up the appropriate SSID and encryption/authentication but still nothing. I am not seeing access points either on the device.
