Internet reliability problems can arise from various factors.
Internet reliability problems can arise from various factors.
Coming from a background in spectrum work, you're clearly struggling with signal consistency despite your claims of being near spec. What's the age of your coaxial cable? Are you certain it's RG6 or 69? Do you have any information about splitters between your modem and the ISP—including outside wall boxes? Checking the line for major bends or sharp turns, and whether staples are securing the wire to prevent pinching. Also, see if any power cables run alongside or near your junction box. You mentioned a powered amplifier before it enters the house; could that be contributing to the issue? Any of these factors seem likely, but as @mtz_federico noted, timing matters—does it happen at specific moments or randomly?
I've experienced worse on my end. Unless Spectrum's setup isn't as reliable as Comcast's. With all these unfixable mistakes, it feels similar to you—it might be a coax problem. It looks like the original poster could have some interference on the connection.
We were expected to stay within certain ranges, but the actual numbers often strayed further. I've experienced worse myself, yet the persistent weak signal is definitely something we need to tackle. This aligns more with what I was hoping for, even though understanding all factors helps a lot. That's why I've compiled this list of things I'd like to know.
Apologies for the delayed responses. Let me demonstrate what the space looks like. Notice the connection in that image? More than ten years ago, someone had a satellite TV service—though the old dish was only just hanging off the roof. Rather of replacing the cable line into the house, they installed this coupling. All of this happened before we moved in. As for the other mess of wires, I don’t know what to say about it.
Additional photos show the cable coming out of the ground, then connecting through main leads to a secondary housing made of thin, unprotected wire. A splitter enters the home, and there are only two rooms with the cable. What does this look like? I’m not an expert.
The wire connecting your demarcation on the side of your home to the basement is quite old. It continues to function properly, so unless the material has deteriorated because of weather conditions, it’s unlikely the problem lies there. Double-check that all components in the box are securely fastened. I’m close to the expressway and railway lines, and I’ve noticed the shaking can loosen these cables.
I reviewed the situation more thoroughly today and it seems the cable isn’t buried anywhere. It starts down, turns right, goes up along the house’s side, crosses the parking lot roughly ten feet off the ground (wind affecting it), and then proceeds through some woods. I double-checked everything was secure and nothing was loose.
The technician arrived around four hours ago and claimed he did his best. He replaced the cabling and stated maintenance would handle the rest on their side. It seemed to improve my connection speed and the modem connects quickly, though there’s now a new problem. Every half hour my link drops and the modem needs to reconnect. This has occurred about six times so far. Should I just wait and hope for a fix, or is there something more going on? What might be causing this? Everything appears fast and stable until it suddenly cuts out without warning. I shared a screenshot of the status page after a clean restart. Thanks.
