Intermittent packet loss with error Unicast Maintenance Ranging attempted - No response and T3 timeouts
My Virgin 1Gig broadband is experiencing packet loss every few days for a few minutes each time. I'm running my Hub 5 in Modem mode and my Unifi UDR7 router records these incidents with exact timings. They usually though not always coincide with errors in the log of my Virgin Hub 5. I've added screenshots of the errors in the Hub 5 as well as general connection info in case there are issues with signal strength etc. I tried rebooting the Hub 5 and noticed there were some fresh errors following reboot so I've added screenshots of those too. Hopefully some of you smart folk out there can point me in the right direction for solving this. Apart from these intermittent dropouts my connection is working great!High packet loss, Area 12
In the B37 6 area of Birmingham, I've been getting high packet loss warnings from about 1520 continuously. The amount is ranging between 19-21% and is causing my router to switch to its fallback connection. There's nothing in the router log to suggest anything amiss, except for dozens upon dozens of profile changes: Time Priority Description 31-08-2025 17:01:29 notice US profile assignment change.

We'd been having consistent connection bounces before that. Approx 2 months ago we had to replace the Hub5 because it completely failed - dead, no power, no response. Any thoughts anyone?
Hub 5x Outage and Firmware Update
Further to previous posts So my Internet only works in DMZ or wih a VPN Without those on Ive run a Ping Test for 5 Min I get spike readings of up to 8000 on a ping Test but settles down to under 20 but seems to go above 500 every min or so Then used another testing site and got this I had no issues until Outage last wednesday and then a firmware update Virgin not helping say resolved but keep probing say relate to outage Total packets Sent: 2620, Received: 319 Call Quality Estimation: Overall estimated call quality score based on round trip delay, jitter, and packet loss rate. 4.5: Excellent (Imperceptible) 4.0: Good (Perceptible but not annoying) 3.0: Fair (Slightly annoying) 2.0: Poor (Annoying) 1.0: Bad (Very Annoying) Your Results: Average Score: 1.18, Minimum Score: 1.00 Packet Loss Rate(%): Packet loss happens when a packet does not arrive, arrives out of order, or arrives too late. > 10.0: Might cause frozen video and broken audio. >= 2.0: Might cause low video FPS, and audio quality might be affected. < 2.0: Video/Audio quality will not be affected.

Hi, seems I am another victim of this disconnect and packet loss issue with 5x hub and 2gig fiber, which occurs every 30mins, which seems to be caused by 'RealSpeed' checking the speed of my connection (?!). Can someone from support PLEASE stop this from happening to my service? I need this resolved asap as I rely on the connection for WFH, competitive gaming and streaming with friends. The constant disconnects are making all 3 impossible to work with. Here's the issue SOLVED by doing exactly that (getting someone to turn off the auto speed testing): https://community.virginmedia.com/discussions/Wireless/upgraded-to-2gig-and-see-ping-time-outs-and-youtube-buffering/5537915/replies/5546444 It's extremely worrying that I can find many threads nearly 2 years old with this same issue. Waited nearly 6 months for the install due to 4 rescheduled installations - now this... feeling like I should've waited for BT to reach my area. 😢Recent packet loss and large ping spikes
Hi. I have recently (maybe in the past month or so, unsure when it specifically started) been experiencing random ping spikes and packet loss, making the internet unusable for several minutes, this includes web pages never loading and online games becoming unplayable due to the high ping and packet loss. This occurs seemingly at random, for about 2 minutes, and then returns to normal, until the next time it happens. I've been with virgin in my current property for over 2 years and have never had issues like this before, I'd maybe have ping spikes once every 4-5 months for a few seconds, and then return to normal but nothing like this. I am on a wired connection to my router, and as stated above, this has been basically flawless up until about a month ago. I've used thinkbroadband.com to get some graphs for my internet over the past week or so, and you can clearly see where the issues are occurring. I've attached graphs for these dates, in reverse order (not sure why they uploaded like this) Sunday 1st June (Now) -> Saturday 31st May -> etc. etc. -> Monday 26th May I hope someone can help. Cheers [MOD EDIT: Images removed]Packet loss
Been getting packet loss for at least 4 months now consistently , Currently on hub 5 router mode, upgraded plan to Gigabit broadband, changed ethernet cable and tried tp link powerline adapters none of them yet to fix my issue. Notes: Gets alot worse when more people are on the wifi. The later in the day the more packets get lost it seems. (Tests taken at 7pm) currently using an ethernet cable from router to computer for this test.Inconsistent service, delayed/late packets or packet loss (BQM, Waveform, Router Logs provided)
Hi. I have been struggling with an issue for months now, and it progressively keeps getting worse. Broadband speeds are fine, I have the 500m package. I do get consistent 500/50mpbs, however playing online games is unbearable, constant rubber-banding and network inaccuracies, constant ping spikes and packet loss to the servers in and outside of the UK, but of course it gets worse outside of the UK. My current setup consists of this: VM Hub3 in modem mode (almost an 8 year old router) TP-Link Archer C80 Cat 6a ethernet wiring (I do not use WiFi for my PC) Things I have tried already with no fix in sight: Restarting and factory resetting VM Hub3 Restarting and factory resetting Archer C80 Testing over WiFi Isolating connection to my PC only and testing Different ethernet cabling My BQM and Waveform Bufferbloat Test: BQM Waveform Bufferbloat Status Item Status Comments Acquired Downstream Channel (Hz) 330750000 Locked Ranged Upstream Channel (Hz) 36599971 Locked Provisioning State Online Downstream bonded channels Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID 1 330750000 12.8 40 256 qam 25 2 138750000 11 40 256 qam 1 3 202750000 10.8 40 256 qam 9 4 226750000 11.3 40 256 qam 12 5 234750000 11.1 40 256 qam 13 6 258750000 11.8 40 256 qam 16 7 266750000 11.9 40 256 qam 17 8 290750000 12 40 256 qam 20 9 298750000 12.5 40 256 qam 21 10 322750000 12.5 40 256 qam 24 11 338750000 12.8 40 256 qam 26 12 346750000 12.8 40 256 qam 27 13 354750000 13 40 256 qam 28 14 362750000 12.8 40 256 qam 29 15 370750000 13 40 256 qam 30 16 378750000 12.4 40 256 qam 31 17 386750000 12.6 40 256 qam 32 18 394750000 12.6 40 256 qam 33 19 402750000 12.9 40 256 qam 34 20 410750000 13 40 256 qam 35 21 514750000 13 40 256 qam 36 22 522750000 13.5 40 256 qam 37 23 530750000 13 40 256 qam 38 24 538750000 13.4 40 256 qam 39 Downstream bonded channels Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1 Locked 40.3 9 0 2 Locked 40.3 18 0 3 Locked 40.3 8 0 4 Locked 40.9 9 0 5 Locked 40.3 8 0 6 Locked 40.3 7 0 7 Locked 40.3 13 0 8 Locked 40.3 7 0 9 Locked 40.3 0 0 10 Locked 40.9 10 0 11 Locked 40.3 10 0 12 Locked 40.3 6 0 13 Locked 40.9 3 0 14 Locked 40.9 7 0 15 Locked 40.9 6 0 16 Locked 40.3 14 0 17 Locked 40.9 6 0 18 Locked 40.9 7 0 19 Locked 40.3 12 0 20 Locked 40.3 7 0 21 Locked 40.3 13 0 22 Locked 40.9 20 0 23 Locked 40.9 36 0 24 Locked 40.9 47 0
xgs-pon with own router...
Well... Wish I was advised of this during signup. Now cancelled BT which I was happily using (albeit without symmetrical 1Gbps upload), constant 0-8ms ping on games such as Fortnite or to Cloudflare DNS/Adguard DNS and a stable speed over to the "upgrade"..... Can't use my own router reliably, double-NAT, no modem mode (could use PPPoE auth with BT and Sky[Sky needs DHCP Option 61 enabled]), consistent 5-8% packet loss to GeforceNOW (plus the extra 6-10ms latency...), fluctuating download/upload speeds mainly affecting the upload (burst: 700Mbps then drops steadily until the end of the test sometimes as low as 300Mbps). BT had a speed guarantee of 700Mbps, what is it here? Is there any chance of using my own router without their router also being in "router" mode? I've tried everything I can think of to try and get it working and now I refuse to spend anymore time on it when the whole network was fine prior to moving to Virgin xgs-pon. The whole product seems rushed through the door so as to not lose out with new customer take up in new areas... When is this going to change? If it isn't in the next month can I still cancel or what because this is the worst FTTP implementation I've used....?WiFi packet loss and high latency. Ethernet port dead
Recently I have been getting constant packet loss and very high latency while gaming on PS5 over WiFi. It has been going on for a week straight now. I have tried restarting my router and my console to no avail. It may be unrelated, but the ethernet port in the wall by my PS5 no longer provides any connection. Looking for any advice or suggestions. My router logs are below.
