Had an engineer out who added a powered booster to the connection and then a lot of attenuator's at the router. Speeds were ok for 48hrs and now the issue looks like its returning as internet cut out last night at around 9pm, also noticed that upload speed is starting to drop as well various speed tests and real speed show it currently around 50mbps. Engineer did say that i have to keep an eye on it for a week and if notice problems to call them back out. Will keep updating this.60Views0likes0CommentsRandom Disconnection from internet
Hi Have issue that every so often the internet losses for around 15 seconds. Everything stays connected wifi/lan but internet is lost. This happens both in router or modem mode. Every time it happens i get the following error on the hubs log:- 12-08-2025 14:58:08 warning DBC-REQ Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value;CM-MAC=**************;CMTS-MAC=**************;CM-QOS=1.1;CM-VER=3.1; 12-08-2025 14:58:08 notice US profile assignment change.
