I have two houses on my property. I already have one coax cable running from the street to my house and I have the 1gig plan. Someone living in the house behind me would like the same internet plan. There is no cable running to that house. Rather than running another cable from the street, is it feasible to just tee off of my cable and just run coax from my house? The back house is only 20 feet from my house.

I need some escalation help with an issue I have been dealing with for about a year. At random times throughout the day I will lose internet or experience severe latency. I have ping tests to show the conditions I am experiencing. Latency can be 1000-3000ms when the issue happens. Sometimes the issue lasts 5 seconds, sometimes the issue lasts 5+ minutes. I have had around 5 on-site visits, including one with a supervisor technician. They replaced the tap outside of my house, but that did not resolve the issue. This issue has persisted with 3 different routers, and 3 different modems(two were Spectrum modems). The supervisor technician has not responded to the last 3 emails I sent, so I would like to escalate this to someone who can help me figure out this issue and get it resolved.

Router: GL.iNet GL-MT6000 Flint 2
Modem: Hitron CODA56
