Internet randomly dropping out since service outage.
We had some internet and TV problems last week due to a service outage in our area. On Wednesday the 20th I received a text message saying that the problem was fixed and that everything was up and running. Since then we have had nothing but problems with our internet dropping in and out randomly sometimes for hours at a time, sometimes coming on for 5 minutes and then dropping out again. I have checked all our cables are connected properly. I have reset the Hub 3 multiple times. I have removed all the ethernet cables that were connected to our Hub 3. I have also reset the Hub 3 to the factory settings. Nothing has worked. Usually the hub 3 shows a solid green light at the bottom, the up/down arrows flash green and the WIFI symbol stays solid green. Other times the bottom light flashes green, the up/down arrows aren't lit and the WIFI symbol stays green. It can switch back and forth between this light show for hours or sometimes just 10 minutes. We've been trying to keep track of the rough up and down time of the internet connection. This is from Monday 26th August. Off first thing in the morning. ON 10:18AM OFF 11:20AM ON 11:36AM OFF 12:20PM ON 12:40PM OFF 12:58PM ON 1:05PM OFF 1:24PM ON 1:55PM OFF 4:57PM ON 6:00PM OFF 6:10PM ON 6:14PM OFF 7:49PM ON 7:57PM OFF 8:01PM ON 9:09PM OFF 11PM Every day before Monday is like this on and off randomly all day. I did login to the router a few times after the internet had come back on and managed to get these from the logs: 25/08/2025 13:34:50 critical No Ranging Response received - T3 time-out;CM-MAC=18::b2;CM-QOS=1.1;CM-VER=3.0; 25/08/2025 13:34:19 Warning!

And why at one point the Hub 3 thought it was 01/01/1970. Though I'd try here first before ringing as it's a lot easier to post some of the information than explaining over the phone. It's also hard to get time to ring during the working week. I've tried to find as much info as I can get but if there is anything else that would be helpful just let me know and I'll try to get it. Any help would be great as I've been customer since the Telewest days and never really had many problems with any of our services. Posting this using my phone as a WIFI hotspot as the Hub3 currently has a solid green bottom light, a flashing green up/down light and a soild green WIFI symbol. Thanks.
