2.4GHz / 802.11n Connectivity Degraded After Omnia TurrisOS 6.3.3 HBS Upgrade

Following recent upgrade of my Omnia my Purism Laptop has not been able to connect reliably to my router and use wireless to install any of three different Linux Distros which I could previously install without a problem.

This laptop is the only device on my 2.4GHz network because it only supports slower 2.4GHz / 802.11n wireless.

Looking for suggestions to resolve/troubleshoot this issue.

The first step for wifi problems is usually “Reset Wi-Fi Settings” in the settings in reForis
