Hi, Over the last 1-2 weeks I have noticed I have started getting a lag on my hard wired connection on Xbox on the likes of Call of Duty and kids having issues on Fortnite. I have since ran a BQM for the last few days and noticed I am getting random spikes in latency which roughly matches the time we have issues while gaming and getting lag spikes.I am not sure if its a network issue or what. I have checked the cable in my house which is only like 1m long as the entry point is right next to the router and the cable is tight. I have even changed ethernet cables just as a precaution but still no change.Please see below my BQMs for the past few days and my router stats, hopefully its a simple fix (I have rebooted the router etc which hasn't helped. I even disconnected the VM cable and reconnected but nope.I have also noticed in the Hub 5 log over the last day I have a few entries saying: DBC-REQ Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided ValueHub 5 with 1gig connection.25/01/202426/01/202427/01/2024 (Red will be when I disconnected everything and made sure all cables were secure)28/01/202429/01/2024 (until 11:40am) 3.0 Downstream channelsChannel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID 1427000000-1.840QAM 2563722110000001.841QAM 2561032190000001.641QAM 2561142270000001.541QAM 2561252350000001.341QAM 2561362430000000.741QAM 2561472510000000.140QAM 2561582590000000.240QAM 2561692670000000.641QAM 25617102750000000.440QAM 25618112830000000.441QAM 25619122910000000.441QAM 25620132990000000.441QAM 25621143070000000.341QAM 25622153150000000.240QAM 25623163230000000.140QAM 25624173310000000.240QAM 25625183390000000.240QAM 25626193470000000.241QAM 25627203550000000.341QAM 25628213630000000.341QAM 2562922371000000-141QAM 2563023379000000-1.840QAM 2563124387000000-240QAM 2563225395000000-240QAM 2563326403000000-1.940QAM 2563427411000000-2.140QAM 2563528419000000-240QAM 2563629435000000-240QAM 2563830443000000-1.940QAM 2563931451000000-1.640QAM 256403.0 Downstream channelsChannel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1Locked40002Locked41003Locked41004Locked41005Locked41006Locked41007Locked40008Locked40009Locked410010Locked400011Locked410012Locked410013Locked410014Locked410015Locked400016Locked400017Locked400018Locked400019Locked411020Locked410021Locked411022Locked410023Locked402024Locked401025Locked400026Locked400027Locked401028Locked401029Locked404030Locked403031Locked40003.1 Downstream channelsChannel Channel Width (MHz) FFT Type Number of Active Subcarriers Modulation (Active Profile) First Active Subcarrier (Hz) 159944K1840QAM 409611083.1 Downstream channelsChannel ID Locked Status RxMER Data (dB) PLC Power (dBmV) Corrected errors (Active Profile) Uncorrectable errors (Active Profile) 159Locked40-3.731204976857152 3.0 Upstream channelsChannel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID 04960000051.55120QAM 64114310000050.85120QAM 64223660000050.55120QAM 643330100000505120QAM 644423600000495120QAM 6453.0 Upstream channelsChannel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts 0ATDMA00001ATDMA00002ATDMA00003ATDMA00004ATDMA00003.1 Upstream channelsChannel Channel Width (MHz) Power (dBmV) FFT Type Modulation 61046.02KQAM 2563.1 Upstream channelsChannel Channel Type Number of Active Subcarriers First Active Subcarrier (Hz) T3 Timeouts T4 Timeouts 6OFDMA20074000000100

Just to add, I have also checked the service status phone number and online and no faults for broadband have been raised in my area.I just find it strange that this has only happened within the last 1-2 weeks which is making me think something has been done in the area.

Went on the Virgin Media website last night to check again the service status and to check for any faults on my line. It prompted I had to factory reset my hub for some reason which I have done. After the reset the connection was even worse and to the point I just stopped playing online games as no matter what game I played I was getting spikes of lag. Looking at the graph it also shows spikes which I am guessing is what I was experiecing. Can someone from Virgin please take a look at my connection and my area as this has only started happening within the last 1-2 weeks! - Connection was perfect before then and nothing in my home has changed. Always have been hardwired.Latest Graph for the last 24hrs

Disapointed someone from Virgin has still not messaged regarding this issue I am having. Its clear as day its mostly happening at peak times which is making me think its a Utilisation issue as its mostly always happening during peak times.

Lag issues which have only recently started happening!

Hi, Over the last 1-2 weeks I have noticed I have started getting a lag on my hard wired connection on Xbox on the likes of Call of Duty and kids having issues on Fortnite. I have since ran a BQM for the last few days and noticed I am getting random spikes in latency which roughly matches the time we have issues while gaming and getting lag spikes.

I am not sure if its a network issue or what. I have checked the cable in my house which is only like 1m long as the entry point is right next to the router and the cable is tight. I have even changed ethernet cables just as a precaution but still no change.

Please see below my BQMs for the past few days and my router stats, hopefully its a simple fix (I have rebooted the router etc which hasn't helped. I even disconnected the VM cable and reconnected but nope.

I have also noticed in the Hub 5 log over the last day I have a few entries saying: DBC-REQ Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value

Hub 5 with 1gig connection.

Started a new BQM monitor once I detected I was having the issues still.

BQM to hub shows nothing much might be as good as it gets for you so get your own router with 1Gb ports to test BQM past the hub in modem mode

  Considering the fact the hub worked perfectly fine a couple of weeks ago, I won't be buying my own router to get the connection back to how it was lol. It has already been confirmed by forum staff and also the tech who visited that the upstream power levels are too high.

If upstream power levels was the problem don't you think your BQM would look worse?

  I don't have a clue which is why I am here asking for help to get the connection back to how it was a few weeks ago. Clearly something has happened within the network. Tech did confirm the hub had stored errors which never cleared so replaced the hub just incase that was to blame and hoped to see the power levels drop within 24hours which they haven't.

Tech visited this morning again and discovered a splitter in the box outside that wasn't needed and could be causing issues. Splitter removed and upstream power levels have dropped. Hopefully this has resolved the issue as tech advised max power level should be 49dBmV. So I will find out at peak times if its fixed but hoping it is.
