Even since the Christmas week, the internet is becoming so bad for me. I checked the log in my cable modem, and I see I got this kind of logs consistently:
| Fri Jan 08 16:39:58 2016 |
Critical (3) |
Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=00:8e:f2:32:0c:a8;CMTS-MAC=50:57:a8:89:a8:76;CM-QOS=1.1;CM-VER=3.0; |
Whenever I see this log, I lose internet connection for a couple minutes. Sometimes I got this every two minutes or so, sometimes every half hour, sometimes every half a day. Don't know what is happending. Even if I didn't see this log, I may still get interrupted connect for half minute or so occasionally.
I have been using Cox for over 2 years, and this only happened in the recent half month or so. Please fix it for me.
Attached the connection from the Modem management interface too, I am using NETGEAR CG3000D-RG
