Uninstall the script and try adaptiveQOS just by itself.
This will check if the issue is within the script or the QOS system.
Yes, two different things at work, and I don't think it is the script as I've taken that out of the picture.
1. Turn Adaptive QOS on, apply. Extender still works.
2. Reboot router, extender connection breaks.
3. Turn Adaptive QOS off, apply, extender still broken.
4. Reboot router, extender still broken.
5. Reboot PC, extender can reconnect.
1. Turn Adaptive QOS on, apply. Extender still works.
2. Reboot PC. Extender still works.
3. Reboot router. Extender broken.
4. Turn Adaptive QOS off, apply. Don't reboot router. Reboot PC. Extender can reconnect.
So, clearly something about QOS, not the script, but also something about rebooting the PC and the router as well is affecting the connection.
