Internet Connectivity

Hello ploustaunau and welcome,

Please review Connection Troubleshooting Tips  as an outstanding first step to check out your connectivity issues.

Hope this helps you out.

Thank you, I appreciate your repsonse. But the tips are not useful. My most important requirement is consistent connectivity, I run scripts that go over the internet every minute and when the connectivity is not there I lose data or my scripts fail and crash other algorithms. I can handle connectivity issues here and there, down for a few minutes, every so often. But recently I have seen much more than that, more than I am confortable with regarding my lost data. I am wondering why this is happening now when it has been pretty stable for months. 

Best,

Philippe

The connection troubleshooting guide is a great place to start. It list common problem areas to check and gives you information on how to check your signal levels(which can cause disconnects). What they also do is give you knowledge so you can approach Comcast with your issue.

ploustaunau,

Have you confirmed that your connection is completely out for a full hour?  I think we are having a similar problem.  We rely on a constant connection and recently have found that the connection becomes intermittent for usually 30 min making it impossible to do what we need to do.  Yes I can surf webpages, but I can't do anything that requires a constant connection like video conferencing. 

The super frustrating thing is when I call tech support, they tell me they don't see any packets dropped when they ping the modem.  I run a constant ping to the gateway and I can see that I can't get 10 complete without having 2 drop.  That happens from any device and none are connected to WiFi.  They want to send a tech out and charge $99 when they find nothing, but can never send a tech when the problem is occurring and it doesn't occur every day or at the same time.  I'm forced to be at the mercy of the connection and have to call every time it goes down.

Your power adapter may be bad.  Unfortunately that was left out of the most recent iteration of the troubleshooting tips although it was in the last one.
