I think your issues are isolated to yourself only - you can't factually state ".....there are issues/failures with the Hub 3" and assume ALL customers who have a Hub 3 are in the same boat.
Thanks for taking the time in responding so politely, it's appreciated.
In response to your instant dismissal of "it's not affecting me so it can't be true", This issue is centered around a poorly chosen component at the design stage (that even the manufacturer, Intel have stated is EOL as of 2018) the core component within the HUB3.
As such it is safe to assume that all hubs are affected (even new ones like mine that is 4 months old) and it is definitely not an isolated issue, as many on this forum are reporting these issues also way back since mid/late 2017.
With that, I have added a small selection of near identical issues I found in less than 10 seconds of searching.
Also, as I have mentioned before, the issue only affects the WiFi and not the LAN ports as the controller for the WiFi fails when it becomes overwhelmed (an oversimplification)
In God we trust, all others must "Reboot their router daily!"
