WCS - Some clients never obtain an IP address

I have a multi-floor building with each floor devided into it's own AP group, with it's own respective interface and VLAN.  Everything works fine ... except for the first floor.  We have wireless carts that have two wireless cards on them.  One is built into the PC attached to the cart, and the other is part of the cart itself for management purposes.

We cannot seem to get the cart monitoring onto the network (while the Windows PC's wireless works just fine).  I have gone over the settings for the AP groups, interfaces, controllers, AP's, etc over and over again and I cannot seem to find anything wrong with the setup.  It seems to authenticate to the AP, get connected, and then never obtain an IP address.  I cannot seem to find any problem with the DHCP server or it's scope.  There are plenty of addresses left to hand out.

Here is a 'debug client' dump from the WCS controller.  Does anyone have any ideas of what I might check?

Thanks in advance for any advice offered!

WCS - Some clients never obtain an IP address

Does the NIC have a static IP?  It doesn't look like the device ever sends a DHCP request.

When you have the issue, can you do a route print on the client?  It could be that the cart's OS doesn't like having two WNIC trying to get on the network.

Re: WCS - Some clients never obtain an IP address

Hello Steve,

This client (and the others like it) are using DHCP.  Although we have also tried configuring a static IP on it to try and rule out a DHCP problem.  When it had a static IP, it would show up as "authenticated" in WCS - but with an IP address of "0.0.0.0".  We of course could not ping the static IP that it held.  Odd!!

I have done some Wireshark captures too, and I can see the occassional DHCP activity going in both directions.  These monitors only wait 2 seconds or so for a DHCP address, and then they don't seem to retry until you reboot them.

We have also had issues with laptops and tablets not being able to obtain an IP address (sporadically).  They will authenticate immediately ... btu then hang forever obtaining an IP address.  Usually after 5 to 10 minutes of retrying, they will mysteriously obtain an IP address and be good.

Again, this only occurs on this floor.  We can take these same devices to another floor - and they work fine.  :-)  It's maddening!!

** EDIT: Also I should note that the two wireless devices on these carts operate independently.  The non-PC card is used to track the location of the cart in the building, and the status of the battery that is connected **

WCS - Some clients never obtain an IP address

For testing, use the wlc as a dhcp and see if the devices get an ip address or not.

WCS - Some clients never obtain an IP address

Are you using different AP models for your first floor? Are all floor APs join same WLC?
What model and software version used with your WLC/WLCs?

in the debug client it shows:

It is obvious that the AP is trying to send KEAPOL-key Message 5 to the client but it does not reply. It tries three times then the timer expries and the AP deauthenticates the client.

In first glance, this is a client issue. I've seen this misbehavior with many such clients like yours when people tried to move from old non 802.11n APs to new 802.11n APs (mainly 1252 and 1142). The clients do not connect to new APs. It was always client issue and people had to upgrade the devices firmware or wireless driver on the client.

One unlucky customer had his clients (wireless guns) out of support so he had to replace them all to get them to work with the new APs. I hope your device is not out of support yet.

WCS - Some clients never obtain an IP address

Hello Amjad,

You may be onto something there.  We have mostly AIR-LAP1242AG-A-K9 AP's and a few AIR-LAP1142N-A-K9's.  The problems seem to be centered around the AIR-LAP1142N-A-K9 models.

These carts seem to work if we take them 'away' to another floor consisting only of the older AIR-LAP1242AG-A-K9 AP's.  I talked with one of our guys here and he said that there is newer firmware for the carts, but it couldn't be deployed because they were not on the network!  I am going to suggest moving them to another area in the building, get them connected, and then upgrade the firmware of the cart to see if that helps.

Should I be looking at upgrading the firmware of the AP's?  From what I understand, that would mean updating the WCS and the controllers, correct?  It may be time to do that.  We are still on 6.0.

WCS - Some clients never obtain an IP address

Hello,

Good that we narrowed down the problem.

You don't have to upgrade the WLC. only on the wireless clients.

Let us cross our fingers that upgrading the firmware will resolve the issue because, as per my experience with such issues, the only solution was to let the client fit well with the AP by upgrading its driver with a driver that understands the new AP model's dictionary.

keep us updated if new firmware mitigates the issue.

Cheers,

Amjad

WCS - Some clients never obtain an IP address

SOLUTION

I was finally able to fix these issues.  I'm not sure what I did that ended up correcting it, so here is what I did.

1) Rebooted each controller.  I noticed on TWO of the controllers that after rebooting them, they showed an incorrect IP address for the interfaces.  Initially when I created the Interfaces I gave them the same IP address across the board (a mistake).  When rebooting the controllers, the old IP address came back like a ghost in a few places.  Odd?  I set it right, and rebooted them again.  This time it "stuck".

2) Updated WCS to the latest version in my branch (6).  Also installed all Windows 2003 Server updates.  Rebooted several times in the process.  Then updated to the latest version available in the v7 branch.  Rebooted again.

3) Updated the software on each controller, one at a time.  Then waited for all access points to update themselves (about 10 at a time). 

That took the better part of a day ... but the problem seems to have gone away!
