Re: Intel 7260 + VHT disconnects

Hi Pasquale

the best way of locking up my laptop wifi (requiring a reboot, no wlans visible, no response from driver), win8.1 + 7260 has been so far the combination of youtube together with Aruba wifi capture being sent to my laptop; please tell my boss it was after hours :)

 

                                         [ internet ]

                                                |

  [ laptop ]       ap215  ---- [ controller ]  --------- [ other AP ]

 

where other ap has 'ap packet-catpure' enabled with a destination IP of laptop, and just let it sniff whatever is going on. The two APs above are not on the same channel (feedback loop), but 'other ap' has various other APs on the same channel just beaconing and sending various traffic.

 

so far 17.16.1.2 is far harder to kill that 17.16.0.x was, but I have still managed to lock up 17.16.1.2 a couple of times, and have reported it to Intel internally.

hello all,

intel has released 18.11.0.8, if you are using 7260, I would recommend that you install it - especially if you are on 17.16.1.2 and still seeing the occaisional lockup requiring a toggle of the wifi card h/w switch.

 

http://www.intel.com/support/wireless/wlan/sb/CS-034315.htm?wapkw=intel+wifi+driver+versions

 

Just to recap, these are the two builds I would be recommending (but prefer 18.11.0.8)

 

17.16.1.2    12/04/2015

==================

much harder to hit issues than 17.16.0.1, but can still lockup sometimes

 

18.11.0.8     22/06/2015

==================

has a couple of fixes for lockups

 

I have been running 18.11.0.8 internally for a couple of weeks and have yet to see any reproduction of the issue I mentioned in my last post - which is a good sign.

 

regards

Re: Intel 7260 VHT disconnects

Thanks for the update, Jeff.

We've been using them for a week on a few workstations w/AP-225s in 11n
mode.. Have yet to enable 11ac on the APs to see if the disconnect issues
can be reproduced. Shooting for next week.

Does Intel not publish the details of their driver releases?

Re: Intel 7260 VHT disconnects

hi Jay

We get a very vague and short list of things that are fixed and told that we cannot publish it - but apparently there are 2 fixes related to bad driver behaviour in this release over and above 17.16.1.2.

Re: Intel 7260 VHT disconnects

This is great news Jeff, which AOS and Instant version should we move to with these new drivers. I suppose anything above 6.4.2.5 (including 6.4.3.x) and Instant 4.1.1.3+

Re: Intel 7260 VHT disconnects

Hi Jeff,

 

We have a lot of the ac-7260 in our environment. Do you know how frequently Aruba update their 'Interoperability Page' http://www.arubanetworks.com/support-services/interoperability/ as we generally refer to this for driver updates, of course, we also do our own internal testing. I ask this as this page is currently recommending 17.13.1.13.

 

Thanks,

 

Darren

vey infrequently; as evidenced by that driver recommendation. This thread is the authority at the moment on 7260AC interop with Aruba 200 series APs
