[nethack009]

I have created a vlan (336) in my core switch to provide internet access to few devices. i am able to get internet access through this vlan through cable from switches.I created a wlan in my wireless controller, Interface and SSID am able to see my ssid and able to ping wireless controller interface IP. I am unable to reach gateway can you some one please help

some questions for you?

1) what kind of controller do you use?

2) who is the DHCP server for the wlan: controller or external device?

Some things to check:
3) is the vlan allowed on the trunk between core-switch and controller?

4) is the vlan "tagged" on the interface of the controller 
     and is this inteface connected to the right port on the switch

5) does the wireless client get a correct DHCP address?

1. model is (WS-SVC-WISM-1-K9) its module inserted in core switch

2.there is now DHCP enabled we are giving statis IP 

3. As per my knowledge all vlans are coming through same trunk  

!
interface Vlan400
