Slow speeds on Gig1

Question

Hello,My speeds used to be fine since Virgin come out about a year ago to run a new cable, although I noticed the last week or so I am getting less than 300mbps. Can someone check my figures to see if something is out?3.0 Downstream channelsChannel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID 13310000003.941QAM 2562521550000003.639QAM 256331630000003.640QAM 256441710000003.940QAM 256551790000003.640QAM 256661870000003.840QAM 256771950000004.140QAM 256882030000004.240QAM 256992110000004.440QAM 25610102190000004.234QAM 25611112270000004.140QAM 25612122350000003.640QAM 25613132430000003.640QAM 2561414251000000340QAM 25615152590000002.840QAM 25616162670000003.441QAM 25617172750000003.941QAM 25618182830000004.341QAM 25619192910000004.141QAM 25620202990000004.341QAM 25621213070000004.141QAM 25622223150000004.242QAM 25623233230000004.241QAM 25624243390000004.340QAM 25626253470000004.141QAM 25627263550000004.142QAM 25628273630000003.842QAM 2562928371000000442QAM 25630293790000003.942QAM 25631303870000003.942QAM 25632313950000003.842QAM 256333.0 Downstream channelsChannel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1Locked411202Locked391203Locked401604Locked40705Locked402306Locked401607Locked401408Locked401809Locked4016010Locked348265416911Locked4038012Locked4018013Locked4012014Locked4012015Locked4019016Locked4114017Locked4114018Locked4110019Locked418020Locked4110021Locked4114022Locked425023Locked4111024Locked4019025Locked4111026Locked4219027Locked4214028Locked4218029Locked4214030Locked4222031Locked421103.1 Downstream channelsChannel Channel Width (MHz) FFT Type Number of Active Subcarriers Modulation (Active Profile) First Active Subcarrier (Hz) 37944K1840QAM 409611083.1 Downstream channelsChannel ID Locked Status RxMER Data (dB) PLC Power (dBmV) Corrected errors (Active Profile) Uncorrectable errors (Active Profile) 37Locked40-1.329383870453&nbsp;&nbsp;Speed tests were carried out from my router hardwired into the modem.

DS channels 10 and 37 are struggling with errors. What are your upstream channels showing?

Check for local faults on 0800 561 0061 and ensure all cables and connections are tight and in good condition.

That's what I was thinking it might be something up with those channels. Upstream is as follows:

Lots of T3 errors on US channel 3. Otherwise largely okay. What does the phone line I gave say?&nbsp;

Go1dy · Answer

Is this via hardwired Ethernet or WiFi?I think the 1Gb router spits out 2.4G and 5G, have you turned off 2.4G in the router setting so it’s all 5G? &nbsp;You’ll never get 1Gb on WiFi on most devices. &nbsp;My iPhone15 only gets about 850Mb max&nbsp;

Is the hub in router mode, so you can let it do a samknows speed test?
