you are gonna need to tell us more than this

autonomous access points? post config

controller based aps? post screenshots of WLAN pages and interface pages (or show run from controller CLI)

how are the APs connect to the network?

I subinterfaces created on a Cisco 892w router ssid and then another to make the clients get no ip address 20.20.20.1 255.255.255.0 that are awarded
the ssid is in vlan 2 IS, I do not know what I've done
This is the running-config and running-config ap

configuration looks pretty good actually

try disabling spanning-tree with "no bridge 2 protocol ieee"

also, try configuring static IP on the client, can you ping 20.20.20.1?

can you do "show interface wlan-gig0 switchport" and post here?

Hi,

If you connect a wired PC to Router directly and put the port in Vlan 2, will that get an IP address ?

Is vlan 2 in the data base and is interface in UP state in router ?

Madhuri

Hi,

Can you issue the following on AP and test :

1. ping 20.20.20.1 source bvi 1

2. I see that you have all the data rates set to basic which could be a problrm for client to connect. Try

conf t

int dot11 0

speed range

and test

3. What happens if you map ssid to vlan 1 ? Will it work fine ?

If that works fine, make sure that you have added vlan 2 in allowed vlan list on the trunk port

Regards,

Madhuri
