Hi, I'm a relative newcomer here. I have Comcast HSI service in Katy, TX, near Houston. Two weeks ago I replaced my rented Comcast modem with an Arris CM820 that I purchased online. It worked fine for a week or so, but over the past couple of days I've seen repeated outages. The "US" light, which had been solid green, is now solid yellow/amber. The manual suggests that is OK, just not as high speed for uploads as before. Today measured (online) speed appears to be 37 Mbps download, 12 Mbps upload.
Looking around at posts I've found that I can get current status of the Arris modem at http://192.168.100.1. However, I haven't a clue what they mean.
I guess I have two requests.
1. Could somebody comment on these signals and tell me if they are "OK"?
2. Could somebody point me to a document that explains what the signals mean?
