I also linked the BQM before. It's even showing the connection dropping. Re: "critical" Network Log Errors Hello Steven_L, Sadly not much has changed, still getting random ping spikes and disconnections, checked the router and the same errors are appearing, still have no idea what they mean.

Edit : I've had a BQM setup since the upgrade and it's been pretty stable until recently, gonna attempt to post the links now lol. https://www.thinkbroadband.com/broadband/monitoring/quality/share/774832bc4db6e869c35be9723a1cc4b16bc22e56 Re: "critical" Network Log Errors Here you go mate, router has recently been reset so not sure how much help these are but I do have a screenshot saved with lots of Pre and Post RS errors (not sure how to post them). 3.0 Downstream channels Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID 1 323000000 5.1 39 QAM 256 24 2 211000000 2.8 37 QAM 256 10 3 219000000 2.5 37 QAM 256 11 4 227000000 2.5 37 QAM 256 12 5 235000000 2.7 37 QAM 256 13 6 243000000 3 37 QAM 256 14 7 251000000 3.2 37 QAM 256 15 8 259000000 3.5 37 QAM 256 16 9 267000000 3.6 37 QAM 256 17 10 275000000 3.7 38 QAM 256 18 11 283000000 3.9 38 QAM 256 19 12 291000000 4.2 38 QAM 256 20 13 299000000 4.4 38 QAM 256 21 14 307000000 4.6 38 QAM 256 22 15 315000000 5 39 QAM 256 23 16 331000000 5.2 39 QAM 256 25 17 339000000 5.2 39 QAM 256 26 18 347000000 5.2 39 QAM 256 27 19 355000000 5.5 39 QAM 256 28 20 363000000 5.8 39 QAM 256 29 21 371000000 5.8 39 QAM 256 30 22 379000000 6 39 QAM 256 31 23 387000000 5.9 39 QAM 256 32 24 395000000 5.8 39 QAM 256 33 25 403000000 5.9 39 QAM 256 34 26 411000000 5.9 39 QAM 256 35 27 419000000 6 39 QAM 256 36 28 523000000 8 40 QAM 256 37 29 531000000 8.2 40 QAM 256 38 30 539000000 8.4 40 QAM 256 39 31 547000000 8.6 40 QAM 256 40 3.0 Downstream channels Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1 Locked 39 52 63 2 Locked 37 288 21 3 Locked 37 157 8 4 Locked 37 56 8 5 Locked 37 23 8 6 Locked 37 25 8 7 Locked 37 21 8 8 Locked 37 13 8 9 Locked 37 16 8 10 Locked 38 20 8 11 Locked 38 20 9 12 Locked 38 22 8 13 Locked 38 38 8 14 Locked 38 32 8 15 Locked 39 22 8 16 Locked 39 40 9 17 Locked 39 37 9 18 Locked 39 46 7 19 Locked 39 54 7 20 Locked 39 40 7 21 Locked 39 49 8 22 Locked 39 45 7 23 Locked 39 58 8 24 Locked 39 50 7 25 Locked 39 47 7 26 Locked 39 60 8 27 Locked 39 59 7 28 Locked 40 65 7 29 Locked 40 63 7 30 Locked 40 74 7 31 Locked 40 78 7 3.1 Downstream channels Channel Channel Width (MHz) FFT Type Number of Active Subcarriers Modulation (Active Profile) First Active Subcarrier (Hz) 41 190 4K 3736 QAM 4096 148 3.1 Downstream channels Channel ID Locked Status RxMER Data (dB) PLC Power (dBmV) Corrected errors (Active Profile) Uncorrectable errors (Active Profile) 41 Locked 42 10.1 1354383107 34 3.0 Upstream channels Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID 0 49600000 41.5 5120 QAM 64 1 1 43100000 41.8 5120 QAM 64 2 2 36600000 41.5 5120 QAM 64 3 3 30100000 41.5 5120 QAM 64 4 4 23600000 41.8 5120 QAM 64 9 3.0 Upstream channels Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts 0 ATDMA 0 0 0 0 1 ATDMA 0 0 0 0 2 ATDMA 0 0 0 0 3 ATDMA 0 0 1 0 4 ATDMA 0 0 1 0 3.1 Upstream channels Channel Channel Width (MHz) Power (dBmV) FFT Type Modulation 10 10.4 36.7 2K QAM 256 3.1 Upstream channels Channel Channel Type Number of Active Subcarriers First Active Subcarrier (Hz) T3 Timeouts T4 Timeouts 10 OFDMA 208 74000000 0 0 "critical" Network Log Errors Hello hope everyone had a great New Years, was wondering if anyone could help me, I recently upgraded to the 1gig broadband package with the new Hub 5 router but I've been having some internet troubles, I've logged into the routers web page and I can't figure out what the problem is, any help would be greatly appreciated, thanks!
