I have an Ubuntu 22.04.4 LTS (with Intel Wi-Fi 6 AX201) that suddenly it just can't access the internet with my home WiFi. It was completely unexpected because it was working fine up until now, and when it started failing I was in an online meeting. It's also peculiar because it sometimes starts working perfectly (ping 8.8.8.8 has a 0% packet loss with <15ms), other times it just goes very slowly (ping 8.8.8.8 has a 20% - 70% packet loss, with >110ms), and other times there's no connection at all (ping 8.8.8.8 has a 100% packet loss, or >3000ms).
The weird thing is:
- I have another laptop with Ubuntu 22.10 where my internet connection was fine (ping 8.8.8.8 consistently has a 0% packet loss with < 15ms). So it seems to be a problem with my computer.
- It works completely fine when connecting to my Android hotspot instead of my WiFi. So it seems to be a problem with my WiFi??
Things that don't work:
- Restarting the computer.
- Restarting the NetworkManager service.
- Restarting the router.
Does anyone have any idea of what is happening??
