Re: dot11radio error: encryption mode cipher not configured

Let me know if this works for you:

interface Dot11Radio0

encryption vlan 1 mode ciphers tkip aes-ccmp

dot11 ssid notknown

vlan 1

authentication open

guest-mode

authentication key-management wpa

wpa-psk ascii 0 cde456cde4

Re: dot11radio error: encryption mode cipher not configured

yes it works.

i don't understand why vlan1, it is in the show config connected to the ssid but the routing and ip adresses is going via vlan2 with bv1 ? why ?

i have the wired network connected to vlan1

kan i make vlan1 bridged and delete vlan 2, so that i have one network as is in the more simple routers ?

dot11radio error: encryption mode cipher not configured

I have same problem, but when I enter command

authentication key-management wpa

I get error: Encryption mode cipher is not configured

But I have (or think I have) configured it. Any ideas what's wrong?

Re: dot11radio error: encryption mode cipher not configured

what nowhere is mentioned in the cisco books i read : building a cisco wireless lan and cisco wireless lan security, is that you first must activate the encryption ciphers on the vlan associated to the ssid.

why is that ?

Re: dot11radio error: encryption mode cipher not configured

Ok... so the post I just made here made absolutely no sense after I re-read the original post. Sorry for any confusion (deleting it now).

In your original output it appears as if you are configuring the encryption mode under the radio, you are adding an ssid, and then you are able to configure the ssid?  Something like:

interface Dot11Radio0

!

encryption mode ciphers tkip

!

!

ssid ssid-PSK

    authentication open

    authentication key-management wpa

    guest-mode

    wpa-psk hex 7

!

What version of code are you even doing this on?

Because any recent version of code that I'm aware of has moved the SSID configuration outside of the radio, which is like the example provided by the first responder. It would be something like:

dot11 ssid ssid-PSK

    authentication open

    authentication key-management wpa

    guest-mode

    wpa-psk hex 7

!

interface Dot11Radio0

!

encryption mode ciphers tkip

ssid ssid-PSK

!

The trick here though is that you have to have the encryption ciphers set on the Radio before you can set the ssid to be WPA.... even though in the running-config the ssid comes first....

So back to my point,   I might be completely way of, so just ignore me if I am,  but I wouldn't expect the syntax to be functionally allowing you to configure the ssid under the radio, if it is also allowing you to use the example where its a dot11 ssid SSIDNAME......
