Maybe clients are too far or too many interference.

No inference and only four client may use that AP.

Hi,

So, did u verify in controller the configuration of APs? Sometimes this problem, can be a configuration in Access Points (such as channels, and so on) checks Aps and verifiy channels (put the acess points in "auto" in the configuration of the channels).

Have you got your APs set up on the WLC in local HREAP mode? If so you are likely to have configured VLAN mappings under the HREAP tab. If the AP has lost its VLAN mappings it will revert to the local VLANs known by the WLC rather than the VLAN(s) used by local Wireless Users. You should check this and if incorrect change the VLAN mappings so that they match those on the LAN where Wireless Users are.

If your clients get an IP connection then looses it, that means the VLAN mapping for clients is wrong. However, if the clients never got an IP address, then check your DHCP scope to confirm that there is available range of IPs for distribution and also make sure that the IP helper-address is configured on the VLAN.

Raj:

What is the security method you use for your WLAN? is it web-auth (layer 3) or some layer 2 security method?

Does the problem happens with client one one specific SSID? or it can happen with whatever SSID?

What is the model/SW version of your WLC? what your APs model?

Some client's have problems when the wireless session times out (especially with layer 3 security methods) and they could not get correct IP address when the session renewed.

So you may need to consider client-side issues and make sure the adapter is working fine with updated driver.

Good luck.

Did someone resolved this

Did someone resolved this problem? Because we have sometimes faced with this, some clients connection to wireless and the after some period have limited access with have no ping to gateway, and other clients have also limited access. We have same controller 5508 (7.4.121.0) and AP1141/1142.

We have found interesting

timur.bessembe — Fri, 23 May 2014 11:33:41 GMT

We have found interesting things, setups on wireless card driver, WMM if it on enable/auto state, we have limited access to the network, when we disabled it have access to network, it only happenning on some laptops with WMM setup. On WLC on WLAN we have Allowed WMM.

Hi,What is the OS of clients?

Pavel Pokorny — Sat, 24 May 2014 08:37:04 GMT

Hi,

What is the OS of clients? There is a lot of articles on internet about problems with limited connectivity in conjuction with Win 8.1 (not Win7 or 8.0, but especially 8.1).

Is this your situation? Or problem is independent of OS?

HTH

Pavel

Hi,OS on that laptops Win8.1.

timur.bessembe — Mon, 26 May 2014 05:20:40 GMT

Hi,

OS on that laptops Win8.1. We didn't saw such problem on Win 7. It's look like with some configuration on driver side. We still under investigation for that problem.

Hi, Try using older driver

Pavel Pokorny — Mon, 26 May 2014 06:23:54 GMT

Hi,

Try using older driver for NIC. Using driver directly from vendor (and not the one from Win) should also help.

The problem seems to be related only to Win8.1 (and some weird Windows update driver version).

HTH

Hi,Yes, it seems like problem

timur.bessembe — Tue, 27 May 2014 05:28:13 GMT

Hi,

Yes, it seems like problem only happening with network card broadcom and driver from OS win 8/8.1, and wlc 5500 AP1141/1142/3600e, we have also wlc 4400, without such problem, but need more test. Now we are resolving, just disable on network card WMM, or just update driver.

Hi,I don't think. I have seen

Pavel Pokorny — Tue, 27 May 2014 06:50:57 GMT

Hi,

I don't think. I have seen the same problem with Intel Centrino 6300 (which is mentioned on internet). Upgrade or downgrade seems to be solving problem.

HTH

Hi,Make sure your Access

abwahid — Mon, 07 Jul 2014 12:36:48 GMT

Hi,

Make sure your Access-point is on low noise channel.

We have resolved this problem

timur.bessembe — Thu, 10 Jul 2014 10:17:38 GMT

We have resolved this problem just update network card driver, because it happens only with broadcom netword card with setup WMM. We have opened TAC, and in dump, we have seen problem in client side.

what version you are using ?

ali aqrabawi — Sat, 12 Jul 2014 21:52:28 GMT

what version you are using ? is it 7.4.121.0 ? or 7.6 ?

there is a similar issues with 7.6 versions with WMM enabled , if the WMM enalebed try to disable it.

does disconnecting and connecting the client again solve the issue ? (it should be :P)

We were using 7.4.100.0 and

timur.bessembe — Mon, 14 Jul 2014 03:15:31 GMT

We were using 7.4.100.0 and then 7.6.120.0 same problem. Yes, we have disabled WMM on SSID, they was no problem connection, no limited access.

so after disabling the WMM

ali aqrabawi — Tue, 15 Jul 2014 18:06:04 GMT

so after disabling the WMM issue solved?
