Is AC-8260 wireless card compatible with 802.11r features.

[OOliv1]

I have some roaming issues with my laptops (windows 10 laptops with Intel AC-8260 - driver 18.0.40.9). I will connect them using 802.11r features. Is it possible? Wireless infrastructure is Cisco Wireless Lan Controllers. Thanks

OlivierWifi,

The Intel® Dual Band Wireless-AC 8260 is compatible with protocol 802.11r. Could you please be so kind and let us know what exactly is the situation you are experiencing?

Hi,

I tried to activate Fast BSS Transition on my Wireless controller but the client shouldn't associate correctly. Here are resume of debugs from my wlc :

1. Association received from mobile on BSSID
2. Marking this mobile as TGr capable
3. Processing RSN IE type 48, length 22 for mobile
4. Sending assoc-resp with status 43 (invalid AKMP)
5. Including FT Mobility Domain IE (length 5) in Initial assoc Resp to mobile
6. Sending Assoc Response to station on BSSID 04:da:d2:8b:a9:99 (status 43)
7. Scheduling deletion of Mobile Station
8. Deleting mobile on AP

Something to do at client side?

Thanks and regards

Hi,

Apparently, my system complies with Cisco requirements. I asked Cisco about my problems but any answers.

At this time, I can't connect the laptop to my Wireless infrastructure using 802.11r. Driver is 18.40.0.

I see the following 802.11i status code :

43 (802.11i) Authentication and Key Management Protocol (AKMP) not valid

Maybe it is not right place to ask question.

How about AC7265 card? Does that card support 802.11r under Windows 10?

Looks Like Oliver and me are sitting in the same Boat, doing the same test, the only difference is i am using Intel 7265.

All helps are appreciated, to narrow down the root cause, let it be at any side, i can drive this if it belongs to Cisco software FT side bugs

Thx

I'm using the AC-7260 on Windows 10. Just upgraded to the most recent drivers (listed above) 19.1.0. Took my card driver to 18.33.3.2 released 5/16. In my controller I'm still not seeing this supporting 802.11r:

In the show client detail I see:

Client Capabilities:

CF Pollable................................ Not implemented

CF Poll Request............................ Not implemented

Short Preamble............................. Not implemented

PBCC....................................... Not implemented

Channel Agility............................ Not implemented

Listen Interval............................ 225

When I look at my iPhone I see:

Folowed by some detail about it:

When I look at my Android phone:

Followed by some detail about it:

Preauth AP................................. 5c:83:8f:b8:5e:6f

Preauth AP................................. 5c:83:8f:b8:63:c0

So either the AC-7260 doesn't support 802.11r or there is still some issue with the driver?

[BStam]

Ignore my comment. According to the link below the 7260 doesn't support 802.11r anyway.
