Hey everybody, I been having issues with my cable internet and or modem. Every day at random times I've been having my connection dropout. Unplugging the cable wire and restarting my modem gets me right back online. I'm trying to find out why this happens. Comcast hasn't been much of a help and I don't want to pay their technician fee to come play with the line in my house when I could potentially fix the issue myself.
I know how to see the signal information for my cable modem (check it out below) but I don't know what the information means, lol. Is my signal good? Do I need attunement? Do I need a new modem? What could be going on? Help me out please. Thanks!
Don't listen to Camryn, he's just trolling it seems.
The downstream power seems pretty low, when it fluctuates you may lose connection. That can be due to splitters before the cable modem, you can make sure you have a good RJ6 cable and no splits between the outside box and your modem. Some modem brands can cope better with lower signal levels than others, but there is no guarantee. I don't see why you would have to pay a technician if your connection is not performing and droping out, they should be able to come out and look at your line without charging you because of the issues you are having.

Thank you for your help. Much appreciated. Do you think if I put a attenuator between my line and cable modem that adds 10db I would be fine?
No, attenuator decreases the signal. An amplifier increases it, however, it doesn't work well for cable modems (even if it is bi-directional, which a lot of them aren't), because it also amplifies noise.
The most obvious thing to look at is splitters on the line, as every two-way splitter reduces the signal in half, by 3.5db on each leg. If you absolutely need to split the signal, use a "tap" instead (it reduces -1db on one leg for the cable modem, and -6db on the other, for TVs).
