Intermittent Internet Connection

Hello,

 

I am losing faith in the Xfinity Internet services. I am experiencing the intermittent internet every day. I noticed that there is a message showed on the modem page "WAN port is unplugged" when I lose the internet connection. I checked the cables for many times and I cannot find anything wrong with the cables. I suspect that there is a problem associated with the cables inside the wall or outside my property. Can you please offer the assitance to help me to resolve the connection issue?

 

Thank you.

Re: Intermittent Internet Connection

Where are you seeing that message ? In a computer's browser. In a router's U.I pages ? Provide details about your equipment.

Re: Intermittent Internet Connection

In a router's U.I pages. I am using Motorola SB6121 DOCSIS 3.0 Cable Modem. I can also see a yellow exclamation mark on the Wifi signal when I lose the internet connection.

What do the modem's signal stats look like ? Try getting them here; http://192.168.100.1

Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

Re: Intermittent Internet Connection

Hi @cyrus1994

You want to figure out if you have a wifi issue or if you have a modem/signal issue. Your downstream power levels are pretty poor, so that's most likely your problem. You can verify this by checking the event log (http://192.168.100.1/RgEventLog.asp) and watching the lights on your modem when you have connection issues. 

 

I've asked a Comcast employee to help you. You should expect a reply in this thread. 

 

Check out the troubleshooting guide while you wait for a reply.

Re: Intermittent Internet Connection

FWIW, the downstream power figures that you posted are out of spec. I now defer your topic to ComcastAmir.
