Instant On - Wireless

Hi Community,
on a site using Aruba Instant On (version 2.7.0 although an older version showed the same issue) we see bluescreens (DRIVER_IRQL_LESS_OR_EQUAL for netwtw10.sys) on our DELL Latitude 5511 Laptops (using Intel AX201 Wifi chip).

We gathered that it only affects 22.140 & 22.150 version of the drivers but same time 22.150 is indeed the last valid driver version for the AX201 in the 5511.

The trouble started when the driver update onto 22.150 came in, but rolling back the driver seems impossible. The DELL systems recognize it would not be the recent driver and updates them again.

I have had hoped that with InstantOn version 2.7.0 things turn for the better - it was not the case.

Is this issue known to Aruba yet? If needed I can provide more version numbers, system information and such.

Edit: I should mention, when an ethernet cable is plugged in to those laptops the bluescreen do not happen.

Also, when the laptop is taken outside the site where a Access Point of any different vendor is in place the bluescreens do not happen.

Best regards,

Bernd
