From eterry at highacres.net Wed May 1 17:33:29 2019 From: eterry at highacres.net (Edward Terry) Date: Wed, 1 May 2019 12:33:29 -0500 Subject: [Tuxaloosa] Network Troubleshooting and Ethernet Message-ID: <97864bd2-ee98-0119-404a-3c4095ecf4cd@highacres.net> Is there anyone on the list, or can anyone recommend someone, who can troubleshoot a Linux network connection and also run Ethernet cable in three houses? The network is between two desktop computers (both running Linux Mint) in two different rooms, connected by Ethernet; it previously worked but no longer does. Comcast is the Internet provider. All computers involved run either Linux Mint or Ubuntu. The Ethernet cable needs to run from the room with the Comcast modem to the room with the television, and Ethernet jacks need to be installed in both rooms. I appreciate any help or recommendations.

My technical knowledge is pretty limited. The modem (which as I understand it is a combination cable modem and router) is an Arris TG1682G and is rented from Comcast. The primary computer is running Linux Mint 17.2 (Rafaela) and is connected directly to the modem via Ethernet cable. The secondary computer is in an adjacent room and is running Linux Mint 18 (Sarah); it is plugged into an Ethernet jack. A cable in the main room is plugged into an Ethernet jack and then into the modem. The two computers are probably twenty feet apart, so not a great distance. I tried replacing all the Ethernet cables (though not the cable between the two jacks, which is probably only about a foot long), but it made no difference. The secondary computer only needs Internet access; the two computers don't need access to each other. Internet is working fine on the primary computer. The Internet connection on both computers was originally set up automatically by Linux Mint. The trouble started when Comcast required us to replace the previous modem (which I will admit was pretty old, but worked fine), so I suspect the new modem may be the cause of the problem, though of course the timing could be a coincidence. Numerous calls to Comcast have not been productive; some of the reps tried to be helpful, but they seem to have even less technical knowledge than I do. I've also Googled extensively but have not been able to solve the problem. I appreciate any suggestions. The two computers are at my parents' house, so I don't have as much access to them as I would if they were at my house, though I'm generally at their house at least twice a day. In addition, if anyone knows someone who would be interested in running Ethernet cable at three houses, I would appreciate any referrals, especially if the person involved can also troubleshoot Linux networks.

Instead, both Host A and Host B are plugged directly into the router's Ethernet ports via Ethernet cable. (Well, Host B is plugged into an Ethernet jack, and the router is also plugged into an Ethernet jack, but I assume that's basically the same thing.) The router is connected to the Internet via coaxial cable. > ?If that diagram describes what you want to do, then follow these > instructions. > https://www.crookm.com/journal/2018/sharing-wifi-connection-over-ethernet/ I'll read through them carefully.
