Can you post your Hub status and logs? 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. The forum software will remove the MAC addresses for you (you may 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!
Thanks for your post and welcome to the forums. It's really great having you on board with us in the Community.
I'm sorry to hear that you are having an issue with your connection. Checking the stats at this end, the connection is looking good. All power levels and signals are in the optimal range and there is no congestion or issues present on the cable you are connected to either. The WiFi side of the network is also looking good with no coverage issues.
I can see the Hub has been online for 3 days but before that you went through some diagnostics using our online help. How have things been since then?
Are you still having an issue with your connection? Pop back and let us know.
