WiFi interface Dot11Radio0 fail to take encryption on 877W

[hardinfw]

Hi

I need to activate WiFi on a Cisco 877W with Advanced IP Services 12.4-15 T1 IOS. The moment I try to configure the encryption it gives me an error message :"No more than 0 encrypted VLANs can be configured for Dot11Radio0"...  I removed the SSID config as well and reapplied the encryption on WiFi interface and got same results...Please assist. Different encryption options give the same results.

Site0030(config)#interface Dot11Radio0
Site0030(config-if)# no ip address
Site0030(config-if)#
Site0030(config-if)#encryption mode ciphers aes-ccm
No more than 0 encrypted VLANs can be configured for Dot11Radio0

Site0030(config-if)#

Did you create the SSID yet?

I tried the configuration by firstly creating the SSID but that does not work either. It gives another alarm:

Site0030(config-if)#ssid skyship

Dot11Radio0 Error: Encryption mode cipher is not configured

Site0030(config-if)#

dot11 ssid BLAH

authentication open

authentication key-management wpa version 2

wpa-psk ascii 0 YIPEE

interface Dot11Radio0

encryption mode ciphers aes-ccm

[hardinfw]

Site0030(config-ssid)#   authentication key-management wpa ?   
  optional  allow legacy clients
 

Site0030(config-ssid)#

Try this since your hardware doesn't support WPA v2

dot11 ssid BLAH
authentication open
authentication key-management wpa
wpa-psk ascii 0 YIPEE
interface Dot11Radio0
encryption mode ciphers tkip

It does not want to take any of the four encryption options...

  aes-ccm  WPA AES CCMP

  tkip     WPA Temporal Key encryption

  wep128   128 bit key

  wep40    40 bit key

Thanks for the help so far! I will check for suggestions on this again in 18hours.

Make sure you create the vlan and then set the encryption type on the vlan before you configure the ssid:

You may need to upgrade the IOS on the router.

Hello,

As per your query i can suggest you the following solution-

router# configure terminal

router(config-if)# encryption vlan 22 key 3 size 128 12345678901234567890123456

transmit-key

router(config-ssid)# end
