DHCP weirdness with ipad/win 7

i have 3200 controller with dchp running on the controller. From time to time, i see ipad or win 7 has issue obtaining ip address from the controller while they connected to the ssid successfully with the logon role.

May be i am not familiar with ipad and win 7. The network settings are looking normal. this is pretty annoying issue. 

Does anybody experience this issue? or may be tips for further troubleshooting.

Re: DHCP weirdness with ipad/win 7

We were experiencing the same issue. 

 

Ended up being that the switch was not passing the vlan information correctly.

 

Check under your SSID Profile on the controller under 

  Wireless > Configuration > AP Group

 

If your using vlan's you need to make sure that the SSID is passing traffic over the correct vlan.

skywalker, 
Have you tried using an external DHCP server?

Re: DHCP weirdness with ipad/win 7

Can you post the following output taken during the issue please?

 

show user ip x.x.x.x (where x is the client IP).

 

What VLAN is the user supposed to be on?

Kudos appreciated, but I'm not hunting! (ACMX 104)
