Daily intermittent dropouts on VM Broadband
Hi All, I am having regular daily dropouts on my home network for all devices where they lose access to the internet for a few moments. Some devices then need re-setting up again to work with internet services regularly. Looking at my router status, I can see Pre-RS Errors but no Post-RS errors and a healthy SNR: Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1 Locked 40.3 188 0 2 Locked 38.9 48 0 3 Locked 40.3 138 0 4 Locked 40.3 42 0 5 Locked 40.3 33 0 6 Locked 40.3 98 0 7 Locked 40.3 62 0 8 Locked 40.3 199 0 9 Locked 40.3 47 0 10 Locked 40.3 85 0 11 Locked 40.3 94 0 12 Locked 40.9 432 0 13 Locked 40.3 75 0 14 Locked 40.9 95 0 15 Locked 40.9 192 0 16 Locked 40.9 71 0 17 Locked 40.3 314 0 18 Locked 40.3 197 0 19 Locked 40.3 170 0 20 Locked 40.9 307 0 21 Locked 40.3 149 0 22 Locked 40.3 104 0 23 Locked 40.3 161 0 24 Locked 40.3 150 0 Upstream however, I do see incrementing TS Timeouts (granted small numbers here): Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts 1 ATDMA 0 0 2 0 2 ATDMA 0 0 1 0 3 ATDMA 0 0 2 0 4 ATDMA 0 0 1 0 5 ATDMA 0 0 2 0 I do not see daily log errors for the issue but I do see some ranging response critical errors and some DHCP renewal errors: 31/12/2024 15:49:41 critical No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0; 31/12/2024 12:43:20 Error DHCP RENEW WARNING - Field invalid in response v4 option;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0; 28/12/2024 23:51:26 critical No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0; 28/12/2024 00:43:20 Error DHCP RENEW WARNING - Field invalid in response v4 option;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0; 24/12/2024 16:57:28 critical No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0; I se a number of other forum posts that seem to be a similar issue which has varied responses, but some mentioned a requirement to replace the router: https://community.virginmedia.com/t5/Networking-and-WiFi/Errors-No-Ranging-Response-received-T3-time-out-and-separate-T4/td-p/5338859/page/3 Can someone please help me work through it as it's driving us mad every time we're in the middle of loading a show to watch or need to google something.
