Modem: Arris Touchstone CM820 Cable Modem.
Router: Netgear N150 Wireless Router WNR1000 v3
So recently I've been having these intermittent outages in my connection that my big name cable/Internet service provider can't seem to fix. My modem keeps losing its connection. Sometimes for 15 minutes, sometimes for hours. And I've recently discovered it might be a problem on my end.
An Arris Touchstone CM820 has five indicator lights. The Power light, the US (upstream connection) light, the DS (downstream connection) light, the Online light, and the Link light. When everything's working fine, the Power and US lights are green, the DS light is yellow, and the Online light is green. All signifying that I've got a solid "ultra high speed" connection. The Link light will be flashing. So that's how it is when it's working normally.
But recently, during these "outages" I've been having, sometimes the Online light will go blank, obviously meaning the modem has lost its connection. And the US and DS lights will flash yellow, in succession, in an attempt to reconnect. But every time it tries, it times out and starts over. The modem fails to connect constantly, sometimes for 15 minutes, sometimes for hours.
Then I found out that this only happens when I have the router plugged into it. I tried taking the router's ethernet cable out of the modem, taking off the coaxial as well, and power cycling it. Then I put the coaxial back on. It was able to achieve a normal connection, minus the presence of the router. And it stayed that way until I plugged the router back in.
Any idea what's going on? I haven't downloaded or installed anything recently or changed any settings, and my router's firmware is up to date.
Gonna also see if the modem loses its connection when I plug my computer directly into the modem, as opposed to through the router.
