WIFI issues with Dell WiFi 6 ax201 Driver

Sophos endpoint leads to no internet connection through wifi. This behaviour was noticed only on one pc in the organization at the moment. This device gets a correct IP address in DHCP mode, but is not able to navigate anywhere.

When trying to ping google, it does respond if connected to any generic WIFI, while it does not respond when connected to the enterprise WLAN (requires domain authentication).

Using enterprise VPN connection the issue does not persist with any WIFI.

Removing Sophos Endpoint solves the issue.

Since it looks very similar, I've tried all the steps and methods showed in this topic: https://community.sophos.com/intercept-x-endpoint/f/discussions/134995/pc-cannot-connect-to-any-wi-fi---sophos-endpoint-is-not-allowing-it, with no results though.

  • We had some strange problems with exactly these adapters, which were solved by uninstalling the drivers, rebooting and let windows do the reinstall. Believe it or not. We had ping to Google ok, but no access to anything in internet. This procedure solved it for us.
