Packet loss for the past four days

I had severe packet loss before, and it magically disappeared after a couple of months. Unfortunately, it has now returned with a vengence. I can reboot the HUB4, which helps for a few hours, but the packet loss always reappears. The effect on my video calls is catastrophic.

Re: Packet loss for the past four days

I rebooted just after 10am... The packet loss has gone temporarily. Does this imply that the problem is with the HUB4 hardware?
