802.11ac clients (Intel Dual Band Wireless-AC 7260) are unable to connect to AP-225

Hi.

I've got a wireless network with controllers (3400) and 30 access points. One of the access point is AP-225. Laptops (Windows 8.1) with Intel Dual Band Wireless-AC 7260 adapters cannot connect to any of SSID (WPA2 with PSK, WPA2 with 802.1x) broadcasting by AP-225.

Does 802.11ac network require additional configuration on controllers? Did someone manage to connect 802.11ac access points using Intel 7260 adapters?

Are you running version 17.x or greater of the intel driver? This was an issue with the early version of the 7260 driver.

Yes, we are running 17.0.5 which is currently the latest version. We didn't try previous versions.

Is there any way to debug that issues on controllers (logs)?

Do a user debug for one of the clients (logging level debugging user-debug ) and then look at the auth logs to see if there is any activity (show auth-tracebuf | include )

I cannot insert output. As soon as I post it, it disappears.

 

Edit:

I've added logs as attachment

mate78,

 

Please feel free to open a support case in parallel.  We do not have enough information to guess what the issue could be here.  All I can see is that you are using termination.

I will open the case but all I want to know is that if additional configuration is needed to enable 802.11ac on access point?

Mayby someone had opportunity to use Intel 7260 with Aruba access points and can share information.

Out of the box, 802.11AC is enabled on the 225 access point.  If you do a "show ap active" the channel should say something like 36E to indicate that AC is running on it.  Even if it is only configured for 802.11n or a/b/g  if a regular device can connect to that SSID, an Intel 7260 device should also be able to, as well.  I got the impression from your post that only your Intel device does not work.  That would require more log gathering to look at your existing configuration.

Re: 802.11ac clients (Intel Dual Band Wireless-AC 7260) are unable to connect to AP-225

Indeed "show ap active" indicates AP:VHT:116E/22/22. All devices that I can use are shipped with Intel 7260 so I'm unable to test it with other chipsets. Thanks for help.
