Thanks for the suggestion. I have a HD 5 min from me.

We have a concrete step that was molded around the sill. 4-9/16 was the only thing that fit. In hindsight we should've demo'd the step and repoured it (especially since it's pulling away slightly), but didn't consider that option.

Having a splitter does not reduce the signal by 50% and is not an issue if RF is properly checked. You can have too much signal and a splitter is sometimes used to attenuate the signal to a cable modem. It’s all about proper RF levels. Splitters are okay.

> Would quarter round trim on top of the brickmould be appropriate?

The only problem I see with quarter round is if it is wider than outermost layer of the face.

Use Azek boards. Home Depot sells them. They are pvc trim boards for exterior use so perfect for this application.

As someone who has been in the coax/cable industry for 17+ years, this can be a number of things. If you disconnected and nothing happened, it may not be active with RF. Usually when we see a splice like this behind a wall plate, it means it’s looping to another outlet somewhere in the house/unit. Only way of knowing is toning the line out or using a meter to check RF levels. Not an ideal way to wire this day and age.

I know this is not a straight forward answer, but the easiest thing would be to call your ISP and have them move the modem and/or test RF signal. You may move it and it works, but the RF may have poor signal and cause service impacting issues.

Really anything that is thick enough to cover the gap, there are quite a few options.

Looks like your jamb depth on the new door should have been 6-9/16" or 5-1/4" - not 4-9/16". That extra wood piece in your picture was probably added becuase the person before you made the same mistake and tacked on their own exterior jamb extension to get the brickmould to cover. You're gonna need to do the same thing. You could do your quarter round idea or something similar, but from a professional's viewpoint - yikes.

You can get vinyl/composite trim strips to fur out with. White is the most common color but I'm sure there are other options.

You could get a Mason bag (kind of like a pastry bag for frosting) and use mortar to fill gap. Tap mounding and brick to give nice clean straight finish.

The moulding only has a few nails but I did apply a healthy bead of sealant when I installed it. Would quarter round trim on top of the brickmould be appropriate?

Up to an inch or so in spots. The reason I didn't want to add wood strips is the moulding and door are composite and I didn't want some random woodgrain in the middle. May not be that noticeable though.

I matched the wires when I replaced my thermostat a couple of months ago. Didn’t take long at all.

You either add wood behind the brickmould or on top of it, not really any other option.

You only need…what, 1/2” to cover the exposed brick/ that spray foam? I’d just pull the brickmould, fur out the exterior face of the door frame the required depth (1/2”) and reinstall the brickmould. Then clean up the brick.

Cable guy here. Call the cable company and make a service appointment. ask the tech to relocate your modem for you.

Most cable companies don’t charge for service calls.

You can do anything if you put your mind to it. ✌️

They ain't cheap, but hot damn they work!

Ahh so is it’s probably better if I just keep my modem up stairs and find a better solution to getting internet in basement? I’m using eero right now but by the time the signal gets to my basement it’s weak, even though I’m hardwired to the euro. I get slower browser speeds and time out of online games.

Please shut the power off to your furnace before doing this!!! R will be energized and you can blow a fuse if you're not careful :)

Modern coax for cableTV/Satellite/outside antennas/Cable modems is RG6; it has better shielding and a larger center conductor thus a bit less signal loss.

As said, you may have RG59 (from back in the days before cable modems) which may work for a cable modem, but is less than optimal. Try it, if it works for you then it's your lucky day. If you have low speeds or lots of errors, the RG59 coax cable in your walls could be the culprit. There's also RG11, but I doubt you will find it in a home. RG59/RG6/RG1 explained.

RG59 is about 6.3mm (1/4 inch) OD (outside diameter), RG6 is about 6.9mm (9/32 inch) OD. Comparison between those two.

Another thing... if you have no idea of what is along the cable run feeding that little junction you pictured, then you don't know if there is a signal splitter somewhere along the way. In the old days of outside TV antennas and primitive cable TV, they would often use splitters to distribute the signal to various rooms.

Today, the standard is to pull a "home run" of coax cable from each room/drop all of the way back to a central point in the home - likely the basement, if you have one. Splitters could be hiding in the attic, or behind walls, but that was generally bad practice - they should have been place somewhere visible.

A splitter is a no-no as you basically lose at least 50% of your signal for every splitter along the way. Splitters are/were for TV signals, but they aren't friends with cable modems.

Finally... the funny little connectors you see usually use a 7/16ths inch wrench, and are called "F" connectors.

Finally... a cheapie tone generator + probe may keep you from going crazy if you have to chase out cables, but don't use on lines with AC power. More expensive ones may come with other doodads and be a higher quality... people that use them everyday spend more for good ones.

Ok thanks I thought I had read some coax was tv only! I appreciate it

Is that a bad thing? This house is pretty old built 1969 although this picture is from an expansion on the house idk when that was built.

Yeah, just hook the modem up and see if it synchs up. That one wire (brass colored ending) is definitely old as it’s RG59.

Yes. They're both carried over the same wire
