Greetings - Comcast just brought installed a new modem (or gateway, whatever they call it). My wife was home for the install, I was not. When I was checking things out my desktop, although hardwired to the modem, had no Internet connection. I can't remember specifically, but I remember the wiring choice the tech made was weird. I rewired the connections. Okay, so Windows tells me I have an Internet connection. I attempt Firefox, no connection. Chrome, no connection. Steam, no connection. The only program that will work is Thunderbird. My TP-Link wireless router works fine, and all of the devices on the router work, browsers included. I almost forgot, I did check and reseat the cables.
I tried a few fixes, some CMD stuff, no luck. I uninstalled Firefox, then it worked again. Then it stopped working. I reset the modem, then it worked again for about an hour. Last night I called Comcast. I spent about 45 minutes on the phone, and the rep basically said it was my computer, they can see the modem on their end and it is not indicating errors. He told me to contact the "website manufacturer" which was obviously read from a script. He also said I could have a technician come out for $40. No thanks. My other options was to bring the modem in for exchange, which after I fiddle with a little more I am going to do. Before the tech arrived I had a working Internet connection, when he left I did not.
I am very experienced with hardware, and some software, but I have limited experience with networks. I think there are ways to trace my DNS requests, yes? I am going to research that and give that a try to see if that is the problem. Does anyone have any suggestions?
