Hi,

here is the way from  the CLI..

en

conf t

dot11 ssid

wpa-psk ascii < new passphrase>

end

From the GUI

AP  Home >> Security >> SSID manager >> Middle of the  scree > key management (WPA2/WPA) >> Provide the key >>  Scrol down >> Apply.

Can you please provide us your AP configuration jsut to make sure that what we need to change is the WPA key and not a WEP key or a loacl user ?

[abukuru95]

Hi Dmantil, it is actually a wep key that i want to change.will post the config. tomorrow when in office. i should maybe delete completely the wep keys and start over again?

thanks for the help guys.

ap1200# configure terminal

ap1200(config)# interface dot11radio 0

ap1200(config-if)# encryption vlan 22 key 1 size 128 12345678901234567890123456 
transmit-key

ap1200(config-ssid)# end


If NO vlan is configured


ap1200(config)# interface dot11radio 0

ap1200(config-if)# encryption  key 1 size 128 12345678901234567890123456 transmit-key


ap1200# configure terminal




ap1200(config-ssid)# end



For further details on setting the wep key use this documentation:

here is my config, i would like to set the password for vlan 105 to for example cisco using wep 128.

thanks for the help.

Hi,

here is the thing!! If we use WEP as the  encryption then the PASSPHRASE should be just a HEX VALUE. You cannot  configure ascii example cisco and all, it should be a HEX value... if  you go for WPA then ASCII is possible... here is the configurations for  both..

USING WPA

==========

en

conf t

dot11 ssid SV
    vlan 105
    authentication open
    authentication key-management wpa
    wpa-psk ascii CISCO
    information-element ssidl advertisement
    no ids mfp client

   end

en

conf t

int dot11 0

encryption vlan 105 mode ciphers tkip

end

USING WEP (ASCII not supported) only HEX ( 0 to F)

========================================

en

conf t

dot11 ssid SV
    vlan 105
    authentication open
    information-element ssidl advertisement
    no ids mfp client

   end

en

conf t

int dot11 0

encryption vlan 105 mode wep mandatory

encryption vlan 105 key 1 size 128bits

end
