Win 11 WiFi drops after Sep Patch Tuesday? Uninstall the Mullvad App

Look, I love the service. $5 a month for the last decade with zero logs is great. But this latest Patch Tuesday completely nuked my Win 11 WiFi, and the culprit wasn't Microsoft – it was the Mullvad desktop app.

Every time my PC rebooted, the WiFi would connect, then the Mullvad daemon would kick in, lock down the network adapter, drop the connection, and cycle it three times before finally stabilizing. It’s infuriating.

The fix? Ripping out their bloated app by the roots and installing the official WireGuard Windows client.

Here is what you actually get when you dump the native app for the barebones client:

• Zero boot drama: WireGuard uses the native kernel driver instead of aggressively hooking into Windows with custom firewall rules. My WiFi connects instantly on boot now.
• Way faster: Because it's a lightweight kernel driver with no GUI overhead, the throughput is noticeably snappier.
• Custom DNS without the headache: I just punched my two AdGuard Home (Raspberry Pi) IPs directly into the .conf file. You still get a native kill switch by checking "Block untunneled traffic."

Between the clunky Linux app and them still not bothering to build a native Apple TV app, it's pretty clear their dev team is entirely focused on backend privacy and terrible at actual OS integration.

If you are dealing with random network cycling, do yourself a favor: grab your config files from the Mullvad site, throw them into the official WireGuard client, and uninstall their desktop app forever.
