You have a lot of Post RS Errors and T3 Timeout errors although these could be past errors.
Have you tried a full factory reset? Hold in the pinhole at the rear of the router for at least 50 seconds and then release (the lights will flash while holding in the pinhole reset button after about 10-15 seconds) then allow 5 minutes for the router to reboot and re-sync the connection.
Please ensure that your WiFi network password is still readable on the Hub sticker before you do this or that you at least have a copy of your original network password 🙂
Once reboot, what speed do you get on https://speedtest.samknows.com/ with direct wired connection from PC/Laptop to router using a Cat 5e cable or better with a 1Gbps capable Ethernet network card?
- Make sure the cable is Cat 5e or better
- Make sure your PC/laptop has a 1Gbps or better network card
- Disconnect all other Ethernet cables from the Hub when running the test
