If priority settings aren't working, have you disabled the software? It has to be enabled to adjust priority on your network.
If those things don't work, try removing it from your windows startup programs and reboot and see if that doesn't fix it. Then it should still work as a normal nic and nothing will have priority.
ok so i downloaded the killer cleaner and the latest driver, i ran the cleaner and restarted, then i installed the drivers and restarted again. i downloaded ccleaner and disabled killer network manager from startup and restarted. it is now gone and internet still works, now i will try download and see if it remains stable. Thanks a lot for youre answer, appreciate it
