Intel AC-7265 on MR42 Nework issue, primarly on Dell Latitude 3150

Over the past school year, I have been getting reports of connectivy issues on a campus with all MR42 APs (current code) and more importantly a school full of (student) Dell Latitude 3150's using the Intel AC-7265 dual band wireless card.  Current driver being applied for the card is 19.1.0.4.

 

I have other, newer Dell models at other locations but with same AC-7265 card and NOT having issues.

 

Very much thinking driver issues, but wanted to see if anyone else out there has had similar experience.  In process of taking driver to V. 19.51.8.2 (most recent from Intel) to see if it helps.

What kind of issue are you experiencing? I have had issues with some Dell computers where they are unable to see the SSID of a connection they previously were able to see. Once I recreate the SSID, everything works fine.

Random disconnects from the known/assigned SSID.  Typically, you can 'see' the same SSID via Windows (10) and reconnect, even though its set to do it automatically.  Sometimes it may take a reboot.  Windows event logs are showing a crash of the driver, which is what is leading me down the driver path....

Kind of a big deal

Driver update will probably do the trick. We've had a LOT of issues with older Intel drivers where we get the same reports of issues you're seeing.

I wonder if this is a roaming issue.  To test if this is the issue could you try disabling "Client balancing" under Wireless/Radio Settings.

Also are you using WPA2-Enterprise mode?  If so, try enabling 802.11r for a trial.  Do this after hours, as currently connected devices might have trouble re-connecting after the change.

No---just WPA2-Personal.  I have, on another network, just turned on the 802.11r 'adaptive' option to see how that works out before rolling it out to my entire school system (we are using a template for 90% of our net).

"Adaptive" basically only works with Apple devices.  You need to go the "whole way" and just enable it.
