Downstream 3.1 potential issue? Causing lag spikes
Hi,
I haven't been on Virgin Media in years, and recently re-joined after some years, after seeing a great Black Friday deal for a combo package. I noticed gaming has been having some delays, with latency varying widely. I noticed down to 3ms, sometimes averaging at 6ms, and mostly around 11ms, while the inherent DOCSIS 3.1 latency spikes that do occur naturally. The download speed is usually in the 1,160+ Mbps on average or higher, but recently has been varying widely, I also recently in the past month or so, have noticed my upload was dropping below 50 Mbps, even though it usually averages around 105-106. When I did speed tests download was okay, varying but usually can go above 1 Gb, but the Upload was dropping below 50 Mbps and then the speedtest will stop halfway on the upload side and the connection would just drop randomly, and a few minutes later pick right back up. Funnily enough, the issue each time an engineer would come out some how corrected itself, and the upload would just go back to normal and not drop anymore. Recently, upload side has been generally okay, I do see dips around 65, and then randomly go back to 105-106. The highest concern is gaming, where the latency varies and sometimes a significant pause would just happen, and then back to normal like nothing happen. I usually use Ethernet, so Wi-Fi is a non-issue.
While looking at the Hub 5 stats, I did notice that on the Downstream 3.1 there was a lot of Corrected errors, and a thousand odd of Correctable errors. What stood out to me was the RxMER Data (dB) is at 0.
I do have an active ThinkBroadband BQM running, I'll attach it, most of the red's was an auto-reboot with a previous router I was using, followed by a forced reboot, and then the bigger red was me switching over to a different router enabling SQM, to hope keep the latency under control a little. I am not sure if the Average Latency is too much, or normal for DOCSIS 3.1, so thought I'd post, to get some answers.
I did open a VM complaint, to get something looked into for the upload side of things. As I wasn't getting anywhere on the phone, as they kept suspecting Wi-Fi was the issue, not understanding that I was on Ethernet only while doing tests, and only Wi-Fi for mobile devices.
I was hoping to get anyone's thoughts on this! Thank-you.
