help with wlan not working

I have a network of multiple WiSM' in different locations. Each has the same SSID's configured. They are all in the same mobility domain. They can all see each other when I look under mobility groups.

The problem I am having is that my guest SSID allows people to connect but are not getting a DHCP address. I verified the DHCP server is working with plenty of leases available. If I hard code the IP address on a laptop I still cannot get out. It appears that I am not getting from one remote WiSM thru to the main WiSM and out to the internet. This was up and running but stopped.

I'm guessing one of Wism is Achoring the Guest traffic, you will need to make sure both WLANs configured the same, to ensure both the data and control paths are up.

That is correct and all paths are up. The mobility group shows up and I verified that the mobility group name is correct on each WiSM, the WLAN ssid is exactly the same and the Virtual IP address is 1.1.1.1 on all WiSM.

We will reboot the WiSM tonight at midnight to see if that clears it up.

All the users who associate to the host WiSM direct work fine. User at the other WiSM's do not.

Re: help with wlan not working

Out of curiousity are all the controllers running the same software version?

New Member

Re: help with wlan not working

yes, all are running the exact same version.

Re: help with wlan not working

Just an update, I did both and MPING and an EPING from the WiSM and both work.

Any suggestions as to why I still cannot get this guest WLAN working?

Is the DNS address reachable from all controllers?

New Member

Re: help with wlan not working

That I will have to verify. Does DNS even come into play in this as each WiSM knows about the others because they have been configured in each WiSM.
