Someone should be spot if there is a problem
Navigate to http://192.168.0.1 (or http://192.168.100.1 - if in modem mode)
Don't log in!
Click on 'router status'
Copy/paste the data from each of the tabs as text into a 'REPLY' as opposed to 'QUICK REPLY'. The forum software will remove the MAC addresses for you (you will likely need to click the 'post' button again).

Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality)
Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum!

Do you have similar issues with wired connections?

The formatting is a bit off - but I can about make it out - Power looks OK - around 6.5 downwards.

SNR looks around 38 - fine

Can you post up the table with the PostRS errors!?

Hub 3 - Modem Mode - TP-Link Archer C7

Which bit is that? How do I find it please?

It'll be in the Downstream tab - It is the 2nd table.

Same in the Upstream tab

There are 2 tables in each tab - 1 containing the specification at which it is running and the other, what errors there have been.
