Errors - ‘No Ranging Response received - T3 time-out‘ and separate T4 time out
Hi, Hopefully someone could help me please with an issue we’ve been having for a month or two? Our Virgin broadband has been fine in general until the last 8 weeks or so, the start of which was when there was a company digging and laying fibre cables in our and adjoining streets as part of an upgrade in the area. I can’t recall the company name sorry, it was not a broadband provider (BT, Virgin etc.) but an infrastructure company. Since then the broadband has gone down multiple times each day. It might just be a coincidence but the timing seems a bit strange. I’ve followed the instructions on Virgin’s website for troubleshooting the router (Hub 3 – around 4 years old), to check if there is an issue with the cable into the house/router, checking cables are tight, soft resets etc. but no joy unfortunately. I’ve factory reset the router, which worked for a couple of hours. A few weeks later I tried putting it in modem mode, alongside another router to deal with the WiFi signals. I did this because we were also seeing Atom errors in the log for a while and thought that might be why it was constantly restarting. The non-Virgin router seems to have fixed the Atom/Kernal restart errors but there’s been no change in the connection to the house staying up, it still drops off completely for a few minutes while the Virgin router reboots. We also just left it all in case it was just a problem in the area for a couple of days/week but that’s not been the case and each time I have checked online/phone number there are no reports of an outage in our area. Thank you for any help you can give us on this.

Regular dropped packets while gaming & T3 timeout errors
Hi all, Hoping I can get some help here as I have tried to use the online service checker and keep getting sent round in circles with rebooting the hub / factory resetting which hasn't resolved the issue. We have recently moved into this house a couple months back and since the install been receiving on and off issues with the stability of the network which is affecting working from home and online gaming. It will be fine for a few days then we will start seeing dropped packets / packet burst in gaming. When working from home this also kicks off the remote desktop sessions I use. Since this has started getting more frequent I have set up a BQM graph and hopefully the links below will work: 26th: https://www.thinkbroadband.com/broadband/monitoring/quality/share/8e0e268fee776ef7500c7d2376ceba20625b96c8-26-06-2024 27th: https://www.thinkbroadband.com/broadband/monitoring/quality/share/a47b50c4e9688abef5cf89e9bb5f36567846ca82-27-06-2024 Also logs from the hub - I have been keeping an eye on the number of timeouts and this seems to have reset recently as a couple days ago looked like this: If you need any more information let me know! Thanks.
