Cisco 9971 and Wireless

Unanswered Question
Jul 29th, 2010


I have this phone using the latest device pack and Call Manager

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.

Any ideas?


I have this problem too.

By any chance do you have any ethernet cable plugged in??

If the answer is yes, unplug it. Notice that you need a power block if you intend to use wireless
