Windows 8.1 compatibility with WLC v7.0.98.218 and DELL DEVICES

[Tiago Marques]

hello,

We have a lot wlc (4400, WiSM, WS-C3750G-24PS and 5500) running on version 7.0.98.218.
Windows 7 and Windows 8 clients are able to connect to the WiFi, which has Windows 8.1 can no longer connect.

we tested two WLAN's, one with security policy: [WPA2] [Auth (802.1X)] and another with [WPA2] [Auth (PSK)], MAC Filtering

in any of the WLAN's the clients with Windows 8.1 did not bind (cannot connect).
the outup obtained is attached

one of the devices which are having problems is a dell laptop E5430.

We've update the wireless card drivers ... according to the dell ... I did downgrade for old version... upgrade to last versions given by broadcom ... but still the problem

can you help me ?!?

Regards,

Tiago Marques

If you want to support Windows 8 wireless clients, you need to upgrade the firmware to 7.0.250.X.

This is a known issue and has been addressed already.

Quick Question,

We are also in the same boat as this thread. 

We are running wlc 4400 with software code (7.0.220.0). We are having issues in Connecting Windows 10 tablets and laptops.

When i did a Debug for the client, i see the client packet is authenticated and it says

 Processing Access-Reject for mobile 44:39:c4:70:09:b0 ,  i assumed it is related to the AUthentication server, but i guess after seeing this is it related to the Software code we are running. Could  You provide ur inputs?

i attached  the debug logs as well , for your reference.

ALso to update , we were able to connect sometimes to the wifi, but not always

That's an old firmware and I'm very certain it's not compatible to Windows 8 and 10 ... unless it's running PSK.

Yes Leo.

Did some more search. Found it is Hitting the bug. CSCua29504.  I have the same symptoms as indicated in Bug(error Logs. 802.1x auth (wpa2 + aes )

To enable that your network is ready for 802.11w and Windows 8 ensure that you are running the latest Cisco Unified releases in your wireless controller network.
