I have seen three cases of this. We are running Cisco WiSM2's and 1142/3500/3600 series AP's. All three laptops were working fine on Win7, and then after upgrading to Win 8.1 they can no longer get an IP address on either our open SSID or our .1x SSID. On a debug, I show that our DHCP server has offered the client an address. In all three cases they were using a Broadcom 802.11n adapter. Specifying a static IP did not work.
I had one user come in and after a little hunting I was unable to find any Win8.1 supported driver from the laptop vendor so I connected two other USB adapters to the same machine and they both worked fine on either an open or 1x SSID. I told the user to downrgrade until a supported driver is published for their adapter/OS combination, or by a USB adapter.

Our Windows 8 users have been fine on our 802.1x wireless network, but any of them that have upgraded to 8.1 are shot. Includes Broadcom and Qualcomm chipsets so far. No one has had any luck so far, but I'm trying to get some users to attempt the driver rollback to see if that helps. Hoping it does. :) -Christopher On 12/4/13, 2:47 PM, T.

That’s what I’m seeing here with the Broadcom and some Atheros cards. I’ve been working on this since Monday (solid) and cannot get any Broadcom wlan cards to connect with Windows 8 or 8.1pro, but if I re-image the computer to Windows 7 pro, it works just fine. We are a complete Cisco shop with about 500 1142N AP’s and 128 1231, 1232 and 1251 AP’s so unless we replace the 1200’s we’re stuck at the 7.0.253.5 code (which is supposed to fix it). But that’s not what we’re seeing if they’re upgrading their computers. All the new computers are working just fine that come pre-installed with Windows 8. Upgrade to 8.1pro and that’s the gotcha we’re seeing too. Thanks for all the suggestions, but I’ve shelved the Broadcom chipset as a “Won’t work on our wireless network” if you upgrade to 8. Now moving on to some of the others that are coming in. Going to be fun after Christmas. /ugh Thanks Shayne From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU>] On Behalf Of Lee H Badman Sent: Wednesday, December 04, 2013 1:23 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> Subject: Re: [WIRELESS-LAN] Windows 8 and Broadcom wireless cards During our opening, and after a Windows update on my own son’s machine at the same time, we saw many cases where both WLAN adapter and chipset drivers both had to be updated to connect to secure networks. -Lee From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Michael Hulko Sent: Wednesday, December 04, 2013 1:40 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> Subject: Re: [WIRELESS-LAN] Windows 8 and Broadcom wireless cards Not necessarily related to Windows 8, but we have had the same issue with Intel Centrino family chipsets. We had the users upgrade the chipset to the latest version available from Intel's site and that seemed to resolve the issues. Never rely on the user to tell you that they have updated the drivers....

We have students that are upgrading their Dell computers from Windows 7 to Windows 8 and the cards stop working on our secure network. They are prompted for 802.1x credentials, and the ACS server authenticates them as well as the DHCP server handing out an IP address, but the computer always states limited or no connectivity. What is really weird is that we have a 1232AG radio and the card will connect ONLY to the A radio, but not to the 1142N-A radio. We are running 7.0.253.5 code because of the older AP’s on campus. We did purchase a separate controller for a test environment which we have running 7.4.110.0 now and it still won’t connect to the 1142n-a radios. Trying to back the driver down to Windows 7-64 bit doesn’t work (won’t allow it to be installed). Any ideas? Thanks Shayne ----------------------------- Bradley University T.
