How to bring vlan up?

[Ed Lo]

Hello,

I'm using a cisco 1941w router with no switch. I have 2 SSID and am trying to ping them but, I noticed that the vlan are always down even when using the "no shutdown" command. How do I bring them up?\

thanks

Below is my configuration:

Hello,

the internal GigabitEthernet interface connecting your AP must be configured as a trunk:

interface GigabitEthernet0
description the embedded AP GigabitEthernet 0 is an internal interface connecting AP with the host router
switchport mode trunk

[Ed Lo]

Is 'switchport mode trunk' a command because I can't get it to work.

[Georg Pauwen]

Hello,

actually, the trunk should be on an interface that looks like this:

interface Wlan-GigabitEthernet0/0
description Internal switch interface connecting to the embedded AP
switchport mode trunk

Do you have the interface in your configuration ?

[Georg Pauwen]

Hello,

in your original post you say:

I'm using a cisco 1941w router with no switch.

What do you mean by that ?

You must see interface Wlan-GigabitEthernet0/0, which is the internal switch interface connecting to the embedded AP.

[Ed Lo]

I just mean that I'm using a router and it's not connected to a network switch.

Ed,

ok, understood. Have a look at the post below, it gives a pretty detailed explanation on how to configure the 1941w. Scroll down to Lukasz Bromirski's post (the 10th post in the thread):
