Cable signal is weak

[ScottSwing]

My cable company (Comcast) tells me I have a weak signal. SDTV works fine, but now I have an HD box, cable modem, and digital phone service that need to be installed. Cable internet and cable HDTV already have intermittent issues, and adding a splitter causes them to fail entirely.
Do I need to find where the cable enters the house and install a splitter? Can the cable company improve their signal?

How can I fix this?

Cox re-wired my home with RG11 from the right at the connection from the house near the street. That gave it more than enough signal to the cablemodem and HDTV (back when I used cable for TV) without a booster.

Re-wired the inside of your house with RG-11??? RG-11 cable and connectors are much larger than 6 and 59. The connectors that i've seen will not work on standard appliances or splitters. Was wondering if you meant they ran an RG-11 cable from their trunk line to your house and split it there and dropped it down to RG-6?

Aside from that, to the OP. I'd say it is the cable companies responsibility to fix the problem without charging you. Especially if you are saying you currently don't have any splitters and the services they sold you aren't working correctly. If they told you you have a weak signal, i would guess they sent a tech out and checked it at you point of entry. If it is weak there there isn't any point of you changing anything until they fix that problem.

It is the cable companies responsibility to have the correct signal levels at the homes external access point , usually a plastic box. After that point it is usually the home owners responsibility unless you have some sort of service contract.

It is the same way with all utilities really. Electric, water, phone all have to provide the correct level of service up to the service connection. After it goes in the home it is your problem 🙂

They did RG-11 through until the last 6 feet or so, then RG6. I was actually pretty surprised they offered RG-11 too.

Comcast provides enough signal for 4-5 splits (not cascading, all home run) depends where your tap plate sits on the main line. If you have more and don't even want to worry about signal again look into one of these

specifically the:

It will amplify the return path so you'll never have to reconfigure for placement of the modem.

If you ever run new cable in your house never cascade (daisy chain) the splitters, you're just asking for trouble. run every line from the outlet to where it hits the house (usually the breaker box area).
