I have a quick router/hub question?

[niwi7]

In my house, I have my cable modem 50 feet away from my router using a 50 foot cord to connect the modem to the router...then the router goes to all the computers in the general area

What I did is set up a computer directly over my cable modem but I dont wanna run another 50 foot wire through the ceiling back to near the cable modem by the computer....so what i'd like to do is get some kind of splitter (i think its called a hub im not sure though), that i can connect the cable modem to: and then plug the 50 foot cable going to my router into 1 port on the "hub" and a 20 foot cable into the other port on the "hub" going to the new computer


what kind of "hub" thing do I need for this?

You need to find out if your cable company supports more than one device on your cable modem at a time. Most companies do not, Roadrunner does up to 5.
If they do support that feature, andy hub or switch will work. Go to best buy and get a small 5 port model for $20.



EDIT:

Should have told you why to check on your cable modem.
Many companies, (Adelphia here) use MAC address restriction on their cable modems so that you can only connect one system at a time, thus the need for a router.

 

[niwi7]

can I connect a second router then?

 

[SaigonK]

You could, but you still wouldnt have a direct connect to the cable modem.


CABLE ---> ROUTER ----> CLIENT PC (this is what you have now right?)

CABLE ---> SWITCH ----> ROUTER ----> CLIENT PC (this is what you want?)
----> CLIENT PC

Another router isnt going to help you. It has a different MAC address.

 

[niwi7]

heres what i want--

CABLE MODEM ----> HUB--------> New Computer on network
------->Router---------->Rest of Computers

 

[niwi7]

heh it gets screwd up when i actually post-- but what i am trying to do is to put a space on the router part maybe a tab or 2 in--- making the hub come out on 1 end going to computer and other end to router

I think you missed one significant point. Unless your ISP provides multiple IP addresses on your connection, what you are laying out won't work. In addition, even if you have multiple ISP IP addresses, you won't be able to share files/printers with the machines on the other side of the WAN interface. I suggest you just run the wire.

Why don't you just put the router next to the cable modem, plug the computer into it, then put a hub or switch where the router currently is? This way everything is on the same network, you don't need 2 IPs, or any extra cabeling.

 

[niwi7]

torghn u r smart and thats a good idea---however a router give seperate ips for everything while a hub just shares the same ip, correct? so...i need a specific ip to connect to my xbox because i use it to transfer songs to it .....so if i did that would my xbox still have a unique id (like for ex. right now its 192.168.2.13)

No, everything connected to the hub or switch will have it's own IP as hub just becomes an extention of the router. The router won't care if it's pluged into the hub or the router it's self.

my router has the only ip that the cable people can see. i only have the one computer,but it calls the router and the router calls the cable modem. modem only talks to the router.

 

[niwi7]

im kinda confused... so will the xbox have its own ip that i can connect to if i connect the cable modem to the router to the hub to the xbox or not?

 

[Torghn]

If you set it up how I recomended then yes. Plugging something into the hub would be exactly the same as plugging something into the router, it wouldn't make any difference at all.

In all fairness there would be some bandwith differences, but I don't think you'd notice them at all. The network would run and operate identicaly in both ways. In this set up a switch would be better than a hub as to maximise speed.

Your xbox will always have it's own ip. Whether it is is assigned by the ISP or by your router. The ip adress you gave us, is a local one, (all ips that start with 192 or higher are just localnet numbers, and class c if you are interested). Your router will connect to the internet, and assign ips to everything connected to the other side of it. You can also add another switch, they are cheap enough too

What I would do is put your router and cable modem in the same place where your new computer is. Connect your new computer, then take the 50 ft and plug that into the uplink port on your new switch, and from your switch, connect all the other computers just as if it were the router.

So your network will look like
..........................New computer
............................... ^
............................... |
............................... |
wall-->modem-->router-->switch--> old computers

Just realized my earler desription will sound vague

ok but i thought that a router gives out a local 192 ip to everything that is plugged into it but switches just share the ip that the router gives it....so if I put a switch where my router is now....won't my computer, xbox and other computer (all hooked up the the current router) share an ip....sorry if im retarted....but if im wrong--- then what is the difference between a switch, hub, and router if youre saying they all give unique local ips to all items connected to them

 

[Tsaico]

heheh ok, not dumb, just new.... A router will connect the outside internet to X inside machines. The outside world see your router as only one machine, and as far as it is concerned that is it, regardless how many machines are actually hooked up. The router will then assign each machine it can ping an internal IP address and route any requests from these machines to the outside world. When a response is given it "remembers" which internal IP number requsted the info and sends it to that machine.

A switch will connect multiple computers together and relay information send to one from another and vice versa. It does not assign any IP numbers only connects. A hub is related, but the entire bandwidth of the hub is shared and it cannot send info to only one specific computer. An example is this: on a switch, computer 1 sends info to computer 2 @ 100mbits Computer 3 is on the internet connected to router. A switch will treat each computer seperately as each one has access to the full 100Mbits of bandwith. It will also send the internet information to the ones where the request origionated. Since a hub's bandwith is shared, the biggest difference is the internet traffic takes up 20Mbits, then the two computers sharing files now haev access to only 80 Mbits of the bandwith. It also sends the information to ALL ports, regardless if they requested it or not. So think of it like this, communicating through swtiches is like calling the operator on the phone and she connects you to the other person. Communicating through a hub is like being in a large room with each other and shouting your information out. The more individuals you add (ie computers) the greater problems you will encounter and loss of productivity.

In some cases, you get the two blended together and life is happy. Some people use seperate machines to do the same thing. Like a VCR and DVD player, similar use, different way of doing it. So when you are connected through a swtich or hub, a computer has to act as a host (server) and the other acts as a client (workstation). When you introduce a router, it acts like a host and all computers will be clients.

Oh another thing, yes, a router does assign 192 addresses, but you are not simply replacing it with a switch. You are buying an addition switch to add to the network. In order for you to keep only one 50ft cable running, you will have to do it this way or buy a wireless access point, see my other thread, to connect it. so you are only moving the physical location of the router, not its function.

So wall to modem, modem to uplink on router. From the router, have your new machine plugged into it from a regular port. Now take your already existing 50ft cable and plug it into a regular port and run it to where your router USED to be. Now there is your new SWITCH and take the 50 ft and plug it into the UPLINK port on the switch. All other other cables from the other computers will plug in this switch into regular ports. When you plug the regular port from router into the uplink port on switch, the switch just becomes an extension of the router's existing ports. So as far as teh computers are concerned, your router simply has more ports in a remote location.

Hope this clear up things a bit.

maybe ill just spend 100 bucks and go wireless


what kind of card do i need for the newly acquired computer? what is a good router--- that meets these specifications--

-will reach up to 90 feet away
-has 4 WIRED ports that can act as my router acts now (with the addition of a wireless connection so i can connect the new computer)

also should i get 802.11b or g? i want to buy for the future b/c i will be getting a laptop in 2 years and if my router works with it it would be a plus...if not too bad ill get a new 1 but j/w if there is any "permanent" wireless technology out now or if its all changing>?

 

[Tsaico]

I don't see what the problem is. YOu won't be spending more then 30 bucks and you have everything else already. and you will be spending 100 on just the WAP. Then you will have to buy the wireless for the comp too.

But as for the wireless router, I don't know about the number of ports, but this is what you would be looking for... I think it is a refurb though... you get the idea... Gor for G, if you are buying wireless, go with the newest standard...

edit: Found it has 4 wired ports... Check out the photos...
