Hi all, For the last couple of months I'm experiencing periodic connection hiccups with my Technicolor panoramic router. I work remotely via SSH and there are periodic (once in several minutes) moments when the remote side is not responding. Kids are also complaining that when they play online games, they keep freezing for a couple of seconds. I've set up a raspberry pi which is connected to the router's ethernet port directly and runs SmokePing. What I'm seeing is that there are periodic packet losses when pinging router's LAN address: https://imgur.com/E94Rx5I You can see the blue dots appear periodically which mean 1 of 4 ICMP packets have been lost. The download / upload speeds are good. The router is connected directly to the cable that comes to the house. But some signal levels look slightly out of spec: Downstream Channel Bonding Value Index 9 1 2 3 4 10 11 12 17 18 19 20 21 22 25 26 27 28 29 30 33 34 35 36 37 38 41 42 43 44 45 46 159 Lock Status Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Locked Frequency 831 MHz 783 MHz 789 MHz 795 MHz 801 MHz 837 MHz 843 MHz 849 MHz 879 MHz 885 MHz 891 MHz 897 MHz 903 MHz 909 MHz 927 MHz 933 MHz 939 MHz 945 MHz 951 MHz 957 MHz 405 MHz 411 MHz 417 MHz 423 MHz 429 MHz 435 MHz 453 MHz 459 MHz 465 MHz 471 MHz 477 MHz 483 MHz 348 MHz 251600000 SNR 37.3 dB 36.4 dB 36.3 dB 36.8 dB 37.0 dB 37.2 dB 37.1 dB 37.0 dB 36.8 dB 36.8 dB 36.8 dB 36.5 dB 36.6 dB 36.6 dB 36.4 dB 36.5 dB 36.5 dB 36.6 dB 36.6 dB 36.4 dB 39.2 dB 39.5 dB 39.6 dB 39.5 dB 39.5 dB 39.6 dB 39.7 dB 39.6 dB 39.7 dB 39.5 dB 39.7 dB 39.7 dB 42.6 dB NA Power Level 7.5 dBmV 5.7 dBmV 5.7 dBmV 6.6 dBmV 7.3 dBmV 7.3 dBmV 6.9 dBmV 6.7 dBmV 8.1 dBmV 8.2 dBmV 8.4 dBmV 8.3 dBmV 8.4 dBmV 8.5 dBmV 8.1 dBmV 8.0 dBmV 7.8 dBmV 7.6 dBmV 7.3 dBmV 6.9 dBmV 10.6 dBmV 10.6 dBmV 10.5 dBmV 10.6 dBmV 10.9 dBmV 11.0 dBmV 10.9 dBmV 10.8 dBmV 10.8 dBmV 10.9 dBmV 11.1 dBmV 11.2 dBmV 14.6 dBmV NA Modulation 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM 256 QAM OFDM OFDM Upstream Channel Bonding Value Index 1 2 3 4 Lock Status Locked Locked Locked Locked Frequency 17 MHz 24 MHz 30 MHz 36 MHz Symbol Rate 5120 5120 5120 5120 Power Level 29.5 dBmV 30.5 dBmV 31.3 dBmV 32.0 dBmV Modulation QAM QAM QAM QAM Channel Type ATDMA ATDMA ATDMA ATDMA Should I call the technicians to check the signal or the router?

Hi MikhailN, I think an upstream impedance may be responsible for your poor Tx levels and intermittent disconnects. This is an issue an on-site technician will need to resolve for you. Email my team at cox.help@cox.com so we can schedule an appointment for you. -Becky, Cox Support Forums Moderator

Technicolor panoramic router connection hiccups

Hi all,

For the last couple of months I'm experiencing periodic connection hiccups with my Technicolor panoramic router. I work remotely via SSH and there are periodic (once in several minutes) moments when the remote side is not responding. Kids are also complaining that when they play online games, they keep freezing for a couple of seconds.

You can see the blue dots appear periodically which mean 1 of 4 ICMP packets have been lost.

The download / upload speeds are good.

The router is connected directly to the cable that comes to the house. But some signal levels look slightly out of spec:
