Hi Andy, You might try and disable " Advertise Quiet IE “ Intel drivers have been found to not cope well when this is enabled. The STA would not to quiet but go silent forever….
Indeed Advertise Quiet IE is a part of 802.11k. -Kees On 19 Feb 2018, at 14:47, Voelker, Andy <[email protected]<mailto:[email protected]>> wrote: Two weeks ago we inexplicably had several models of laptop completely cut off from our wireless network. On many when they went to look for available SSID’s the driver would either crash or all networks would disappear. On others they just wouldn’t connect to any of our networks, even the open guest network. All work ok off campus. We finally tracked it down to two intel chips: Intel AC 7260 Intel Centrino R Ultimate-N 6300 I discovered that the problem disappeared when I disabled 802.11k. We’re an Aruba shop. We haven’t done any updates or major changes to our network since October. Those models couldn’t have all received a bad driver at the same time. I think we were able to find a driver that fixed the Intel AC 7260, but they stopped making updates to the Centrino. Has anyone else seen this suddenly? Next I’m going to try to tweak some settings in 802.11k to see if I can re-enable it without the offending setting. -Andy Voelker Network Administrator Davidson College ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
