Hello,
With Blokada deactivated, could you try downlading the tool from Hurricane Electric:
Then both with and without your WiFi activated:
- Hamburger menu → Ping
- IP Address: 2606:4700:4700::1111
- Protocol: IPv6
- Go
Let me know if you get any packet loss in the ping stats.
If you don’t get any loss. Could you please send us the log right after the issue has occured?
