Astronomical RS errors are not good though it could be router related.
Switch the Hub off and unplug it for a few minutes and then start up. When done, check back in the settings and ensure that the RS error counts have all reset to 0. Then check every hour or so for the next day or two to see if they start reappearing - they shouldn't.
If they do try taking the Asus off for a while and run the Hub in normal router mode and see if they are still appearing then
Also, in the meantime... If you haven’t already, set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.
