Re: Significant number of Pre/Post-RS errors and T3/T4 timeouts
Hi, I have now reset my hub 5 and I will keep an eye on it and see if the issue occurs again. If it does, I would like an engineer visit arranged and escalated further as I have had several engineer visits for the same issue over the last 12 months.206Views0likes1CommentRe: Significant number of Pre/Post-RS errors and T3/T4 timeouts
Hi, I believe you have checked my Hub 5 but in the Hub 5 device information page it states that it has been up for just under 3 days. Something is not right. I will reset it tonight and see how it goes. Info Hub 5 device information The information below shows current status of this Hub 5. Standard specification compliant: DOCSIS 3.1 Hardware version: 1.1 Software version:LG-RDK_7.6.20-2306.5 Cable MAC address: **:**:**:**:**:** Cable modem serial number:YAAS13418XXX System up time:2day(s)14h:18m:8s Network access:Allowed705Views0likes2CommentsRe: Significant number of Pre/Post-RS errors and T3/T4 timeouts
Please see the graph - https://www.thinkbroadband.com/broadband/monitoring/quality/share/20fec4ae8ea479b397fce22246a50bc8c72e6d06 Multiple devices both wired and wireless affected. Webpages, videos, and downloads hang and don't load. Then when I look at the T3 timeouts it increases on both the DOCSIS 3.0 and 3.1 upstream channels. The issue isn't speed as such, it's the upload timeout that manifests in the loss of internet. Please see below and tell it the service is acceptable. I argue it is not acceptable and it has not been acceptable for some time. 3.0 Upstream channels Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts 0 ATDMA 0 0 12 0 1 ATDMA 0 0 7 0 2 ATDMA 0 0 18 0 3 ATDMA 0 0 9 0 4 ATDMA 0 0 56 3 3.1 Upstream channels Channel Channel Type Number of Active Subcarriers First Active Subcarrier (Hz) T3 Timeouts T4 Timeouts 6 OFDMA 200 74000000 55 3794Views0likes4CommentsSignificant number of Pre/Post-RS errors and T3/T4 timeouts
Hi, I have a significant number of Pre/Post-RS errors on the downstream and T3/T4 timeouts on the upstream. I have tried rebooting the Hub 5, making sure the coax cable is tight and resetting the Hub 5. I had an engineer visit on the 8th of June but the issue reoccurred shortly after the visit. Any ideas? I seriously do think that the cab I am connected to has issues as this has been a pattern over the last 12-18 months. Please see the stats from the Hub 5 in the replies below1.3KViews0likes11CommentsRe: Significant number of Pre/Post-RS errors and T3/T4 timeouts
