Comcast Internet Question, Warning: Crappy Paint Diagram Ahead

Goodfella2487

I currently have a computer located on the second floor of my home running on a wireless internet connection. The wireless router is located downstairs on the other side of my home, so the connection can sometimes be a bit shoddy. My question is, since I have a direct cable line running into my room on the second floor, could I simply split the cable line in my room, plug it into a Linksys router and then directly into my PC, or will I need to connect a second Comcast modem?

Any help is appreciated, thanks.

afaik neither of those would work. I am 100% sure the first idea doesn't work and almost 100% sure the second idea wouldn't work.

Either you get a stronger wifi router or you have to run a cat5/6 cable to the modem that hopefully has a built in router.

The wifi built into the units that the ISPs have out usually aren't that good quality. Are you at least running Wireless N?

I asked about getting a 2nd modem from comcast and they don't do that, though that was 2 years ago.

I second the notion that it's either get a better/more optimal wifi set up or run network cables.

What's your budget?

$50 can get you a 1000 feet of cat5.
$150 can get you a ethernet over coax
$100-150 can get you ethernet over power

Personally I'd just run the cat 5 through the walls. Easiest solution, fuck it, upgrade your whole house! There are issues to ethernet over XYZ solutions. Power needs to be on the same circut, the coax can't usually have anything else running over it, etc.

I just bought some pre-made Cat6 cables and ran them throughout my home. So now I have an all Cat6 Gigabit home network.

run a cat5 or cat6 cable through the wall. You can't just plug in a second modem into a different cable outlet without some problems, and your internet will be more reliable/able to reach higher speeds while plugged in, I still don't have a wireless card in my computer because I don't trust wireless connections unless I am within 10 feet of the router/modem and not going through any walls.

The other option would be to purchase a good wireless router and see if you get a better connection through that then the modem's built in crappy wireless

Always a solution. When I get a house I plan on running cat5/6 through the walls and adding face plates/jacks. $80 investment and some time, maybe a little drywall patching/paint and you've added a lot of value to your house!

You can use a splitter upstairs on the second floor and plug the comcast modem into that cable line. Effectively moving your modem and wireless router upstairs.

The only potential issue is if the signal (on the coax) is weak from outside the splitter might weaken the signal too much leading to unreliable internet service.

Moving the comcast modem upstairs is probably the easiest solution. The other solution like others have pointed out is to run a cat5/cat6 cable from your router downstairs to your pc. You can follow the existing coax run.

If there is nothing on the first floor that is directly plugged into the router (besides the modem), i would just move that and the modem upstairs. So my question to you is why exactly does the modem and router need to be downstairs? Is there any particular reason that demands it?

Easiest option: switch the cable modem and router to the room that the TV is in. That should only take one splitter so it should be okay.

Medium difficulty: move the router downstairs into more central location, or try to put as few walls or metal objects between the router and the target computer

Hardmode: Run cables through the walls

Hardmode is pretty easy if you're handy with a screwdriver, a drywall saw, and maybe a wire snake if you've got insulation you need to get through.

Hopefully the OP does it too. The scariest part of all that is cutting the hole in drywall!

Will be bookmarking that article. Would like to run some CAT in my condo too. Might as well since we'll be here forever.
