Moving my Modem to a different room?

[Reventon]

I want to move my modem from my office to my own room, due the office is really no longer being used and I want direct connection instead of wi-fi. I tried this once before and for some reason I didn't manage to any connection when I plugged it in here in my room. I want to try again to see if it works this time... am I missing something?

What kind of modem? Dial-up (unlikely), DSL, Cable, other?

 

[Reventon]

Cable.

 

[m4gicfour]

Check what kind of splitter is between you and the service line that comes into the house. If it's an older house, there may be more than one splitter in different areas of the house.

Cheap splitters can kill the (pretty sure it's) high frequencies used by the modem. If you find that the splitter is the problem, these are cheap and supposed to work with cable modems.

 

[Reventon]

I think we just had the splitter installed not much more than 2 years ago.

 

[m4gicfour]

Still, check what it says on it. Most splitters don't pass the higher frequencies because the higher frequencies aren't used for video.

If that's not the problem, could be a damaged cable letting too much interference through, or a poor quality cable attenuating the signal too much. If there's multiple splitters between you and the service line, that could be it too. Splitters drop the signal strength pretty substantially.

Beyond that, you'll have to wait for somebody that knows a bit more about cable modems.

Exactly what m4gicfour said, some splitters are even labeled as digital splitters but are rated for 5 - 1000MHz. Those are the ones you don't want.

What you don't want

 

[Reventon]

Mine is labeled as 5-1002Mhz.

 

[m4gicfour]

Yup. That could be the problem then.

Does the cable that you normally plug the modem into pass through that splitter as well?

 

[Reventon]

It goes wall -> cable -> splitter -> one cable to TV -> one cable to modem

 

[m4gicfour]

Really?

So


EDIT here we go:

 

[Reventon]

Splitter is outside the wall. This is all in one room. I run my computer in my room on a wireless setup right now.

 

[m4gicfour]

So you've got cable connections in other rooms, and your picture is how it's set up usually when the modem works, right? Is that splitter the one that has 5-1000Mhz? I would have thought it would be a problem but maybe your modem works within that range.

If you've got cable connections in other rooms it means that there's another splitter somewhere (or the cable company's service entrance box has some type of splitter built in). If it's the second one, the cable company's box might have a specific port that the modem's supposed to use. If there's another splitter somewhere, chances are there are actually several splitters throughout the house.

The way houses used to be wired, they would daisy-chain splitters:

Service -> splitter 1 -> Room 1 / Room 2 / Splitter 2 feed -> Splitter 2 -> Room 3 / Room 4 / Splitter 3 feed -> splitter 3 -> Room 5 / Room 6 / Room 7

The way they do it now (Called "Structured Wiring") they keep everything at a central location

Service -> Eight way splitter -> Room 1 / Room 2 / Room 3 / Room 4 / Room 5 / Room 6 / Room 7


You can see why structured wiring is better. One splitter, all lines go back to one spot.

If you've got the old style wiring, the problem splitter might be anywhere. If you've got structured wiring, then the problem likely isn't a splitter, but something else since everything would be coming from the same splitter.

I just don't know enough about the setup of things in your house, and enough about cable modems to say much more, and I don't want to tell you to go buy something if it won't help.

 

[Reventon]

Yes, the visible splitter is the one that is 5-1000Mhz. However, when I move the modem to my room, the modem gets no internet connection. I'm not sure if it's because it takes a while to establish a connection, but the last time I tried this plan failed to work. It may be possible my room has a bad connection, because everywhere else in the house has a fully-working connection.

 

[m4gicfour]

Yeah, could be. Cable modems can be touchy about the signal too.

It's hard to say what the deal is in your house, you never really know what's going on inside the walls unless you were there when they wired it.

The only thing that my experience can tell you past this point is try plugging everything in, and then unplug the modem from power, wait 15 seconds, and plug the power back in. A friend of mine once had a cable modem that refused to give a connection after it was disconnected from a computer unless it was rebooted a few extra times (who knows why)

 

[Reventon]

I might switching up again real soon here before I go to bed. Hopefully moving it will solve my connection issues I'm having with my wireless setup.

Log into your modem 192.168.100.1 and post your

Downstream dBmV and Signal to Noise same with upstream

 

[Reventon]

 

[m4gicfour]

You should probably do same with it connected (physically, that is) in your room for comparison.

 

[Reventon]

Yeah if I can ever get any connection

 

[m4gicfour]

You don't necessarily need an internet connection, the 192.168.100.1 address is on your modem and should work whether you can access the internet or not.

 

[v12dock]

Wow your downstream signal is very low you should try it without a splinter. You should consider calling your cable company and get that investigated

Who is your cable provider?

 

[m1dg3t]

Might need a signal amp/booster

 

[1freedude]

Might not be any signal.
Hook a tv up to it to check connection.

My advice is usually the same in situations like this: don’t ever assume that the data (or signal) are getting there. In this case, take out the middle-man...the modem. If a tv works, think about finding the signal leak.

If the tv doesn't work, take the plate off and see if there actually is a cable in the wall.
Do some digging, find the other end, make sure all junctions are tight.

Just an example...I have telephone jacks in almost every room, but only one is connected to the street.
