Two modems and one router?

February 24, 2011 at 09:54:15
Specs: Windows XP
I recently moved into a new place and suscribed to and ISP which they gave me a modem. I have been planning on buying a a cable spliter and router but in the meantime, I have been switching the cable from the cable box to the modem when I need internet. Well, a friend moved in and he brought HIS modem from same ISP and a wireless router and set it up upstairs. Now there is a modem upstairs and a modem downstairs and a wireless router upstairs. My kids are complaining that they cant connect wirelessly when the internet is being used upstairs. My goal is to be able to have two xbox 360's online- one upstairs and one downstairs, one netbook and two Jurrasic PC's which probalby are not wireless, My roomate prefers to hardwire his xbox to a router as he says its faster that way. Is the problem my kids are having downstairs just that the wireless router is too weak? Is it ok to have to modems connected (the one upstairs to the xbox? and the one downstairs?) Thanks for any insight. Im very "un" about networking.

Your roommate should know better.

He has sole custody of the internet connection.

You can not connect two modems at the same time. Period.

Hope he's paying for the internet connection.

I wonder why I can play xbox live downstairs while hard wired to my modem and he's upstairs playing xbox live hardwired to his router/modem. I just got off the phone with him and his offer was to buy a super duper wireless router but he will stay hard wired to it, but everyone can get on wirelessly. Do you think that the rourter is the problem for the slow connection or because two modems are being used?

What service are you with? I want that service as long as I don't have to pay double!

Normally you only get to have one modem which is provisioned by the provider. Additonally you only get one ip address.

You appear to be getting both; double modems and double ips. Usually this is a result of a technician being sloppy in their work. Eventually they will figure it out and only one modem will work.

Hopefully you won't get a bill for both.

Wireless is always slower than wired due to the overhead wireless has which wired doesn't.

Your slowness would be due to you now have double the equipment on the line.
To test the accuracy of this disconnect the roommates router and see if your xbox speed increases.

Did your roommate cancel his original service? If so when? Reason I ask is I am wondering if the provider still sees it as a live connection though not in the same location anymore. Perhaps the work disconnect order hasn't gone thru yet.

I thinks thats exactly it...he hasnt stopped his service at his old place but brought his equipment over and its still working under his acct. Im told an ideal set up for my 3bd townhome would be a simple modem to wireless router. I would be willing to let him have the placement of the one modem and router in his room provided that my kids and I can still connect at a reasonable speed. Right now my son says that he can only connect on his netbook wirelessly when the roomate is not home!

Now I am wondering if I should purchase a more powerful router AND/OR upgrade to faster speeds via comcast? Any advice would be great, thanks so much

You speed is dependent on the slowest link. In almost all cases that is your ISP. You might be able to get a better wireless device that prevents loss signal issues but in most cases the wireless will work faster than your cable connection will. My guess is signal problems probably do to other wireless devices, metal in the walls, cordless phone, microwaves or what ever else. You can install the following on your laptop to see which channel has the best signal and where the dead spots are in your house...

Take note of what channel your neighbors are using and switch your wireless channel to one they are not using.

"Right now my son says that he can only connect on his netbook wirelessly when the roomate is not home!"

Not sure what this means. When your roommate is home is he connecting to the wireless with another device like a laptop? What is it that your roommate is doing when he is home that might be causing problems with your wireless?

"You speed is dependent on the slowest link. In almost all cases that is your ISP."
So does this mean I should upgrade to higher internet speed?


My roomate has his modem connected directly to the cable outlet from the wall, Then he has a wirless router hooked up to that modem via ethernet. Then he has a xbox 360 and internet capable surround sound receiver hooked up direclty to that router via ethernet cable, so he is not using anything wirelessly. When he is home he is either playing xbox 360 live or on netflix through his xbox. My son can use his netbook anywhere in the home wirelessly when my roomate is not home and logged off the internet. When my roomate is home and online using his xbox, my son has very very slow connection with his netbook. So I am wondering what do I need to do to resolve this. Also, I will be setting up my xbox 360 downstairs very soon and plan to do this wirelessly. Sorry if Im not being too clear, I basicly need a A-B-C, 1-2-3 directions in the simplest laymans terms possible.

In short, do I buy more faster internet speed with comcast or do I buy a better router? or do buy both? Or is there something else that I should do like remove one of the modems in the home? Or something else? Thanks so much!

The xbox is getting priority over wireless for that internet connection.

My suggestion is you get your own separate internet connection with your own router. Isolate wireless to only your family access. This will end any conflict over internet access which is bound to get nasty.

It would be better to have service not in common with your roommate.

Xbox works better wired than wireless as does any game being played. I would suggest wireless is not your best option for gaming.

Anything else you need to know?

i also have roommates, we were sharing connection but i decided to have my own modem, so now there are two modems, i pay for my own service and they for theirs, so we get two ip's but its on the same account. there can be two modems under one account, but not two accounts on the same address, thats what the people at comcast told me. you need to have your own router to have a wireless signal. if you dont have your own router and can connect wirelessly then you are using someone else's wireless signal. if you have your own router and your roommate his own router also, then you have to connect to your own wireless signal -you need to check the name of the signal to make sure it is yours. also, secure your wireless signal with a password so other people dont connect to it.
and call your internet service provider, they should be able to answer you these questions.
