High correctables and frequent packet loss
High I am experiencing frequent packet loss on my connection and modem shows a high number of correctables Support just keeps telling me its my wifi when it clearly is not. I now have my modem connected directly to the line coming into my house. No splitters or anything. Here is a screenshot with an extremely large number or correctables after <12 hours of uptime. https://imgur.com/8DhrAmI I seem to be having packet loss throughout the core hours of the day. The packet loss is not consistent and comes and goes. It can be anywhere from 1% to 35%. This makes voice communication near impossible. My speed tests are ok, I just have loss. When I take packet captures I have seen a large number of re-transmits. During the night and early morning my packet loss is minimal. The loss seems to be at the first hop, so seems to be some issue between me and the first hop into the cox network. I have tried to remove any connectivity issue in my house by connecting the modem straight to the line coming in. Here is an example ping to google.com with high loss, most times it is not this bad, just giving an example of a worst case --- google.com ping statistics --- 30 packets transmitted, 22 packets received, 26.7% packet loss round-trip min/avg/max/stddev = 21.592/91.424/291.184/71.318 ms A traceroute shows traceroute to google.com (172.217.11.14), 64 hops max, 52 byte packets 1 192.168.1.1 (192.168.1.1) 1.969 ms 2.959 ms 2.705 ms 2 10.4.176.1 (10.4.176.1) 94.864 ms 50.357 ms 14.130 ms 3 100.120.244.34 (100.120.244.34) 39.860 ms 20.208 ms 40.469 ms 4 100.120.244.176 (100.120.244.176) 31.100 ms 151.296 ms 27.478 ms 5 nyrkbprj01-ae3.0.rd.ny.cox.net (68.1.5.157) 50.367 ms 119.706 ms 218.165 ms 6 nyrkbbrj01-pos000102.r2.ny.cox.net (68.105.31.73) 96.894 ms ip70-167-150-241.at.at.cox.net (70.167.150.241) 25.395 ms nyrkbbrj01-pos000102.r2.ny.cox.net (68.105.31.73) 51.504 ms 7 * * * 8 * 172.253.70.17 (172.253.70.17) 116.994 ms 108.170.248.33 (108.170.248.33) 68.717 ms 9 172.253.69.209 (172.253.69.209) 198.901 ms 108.170.248.116 (108.170.248.116) 27.256 ms lga25s60-in-f14.1e100.net (172.217.11.14) 44.228 ms If I ping the first hop directly I get packet loss as well --- 10.4.176.1 ping statistics --- 50 packets transmitted, 47 packets received, 6.0% packet loss round-trip min/avg/max/stddev = 8.183/46.852/320.911/54.797 ms you can also see that the ping times are all over the place with a stddev of 54 ms Pinging my router I have zero loss --- 192.168.1.1 ping statistics --- 50 packets transmitted, 50 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 1.192/3.042/11.697/2.927 ms
