Hi, last week we put our superhub into modem mode and added an asus ax86u router. All worked well for a few days. Much improved connection. So fast. But now we seem to have issues. Speed is reduced again and yesterday we lost connection totally. I have rebooted the router. Im a bit of a novice and trying to do all this with lack of knowledge! My son has severe learning difficulties and i need a stable connection so he can watch his youtube videos. 

Is there anything i should be doing to make this work better. We seem to have gone back to the issues we had with our superhub regarding service. I have a think broadband monitor set up since we added the asus. I had one on the virgin router too but that went solid red once the new router was added. Funnily enough that started showing stats again the last few days, didnt think it would. I have disabled that one now.  

Any help would be gratefully received for someone who is clueless on how to sort this. Many thanks

I am trying but it keeps telling me to sort highlighted areas and try again. 

Finally it let me. Thank you for your help

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.

I have a monitor set up already. I will try to post it here.

Hope this works!

works fine - looks horrible.

as @jbrennand says, try rebooting the hub, check the errors are at zero and then post the stats again tomorrow..

I'm not convinced that it could be the asus router though - but I've been proven wrong before.. this looks like an issue with the connection itself. 

[jbrennand]

OK can you try with the Hub in router mode and the Asus off. If the issues and packet drops remain will indicate and issue with Asus connection rather than the Hub per se.
