I have 2 computers in one room and only one network cable. My router is in
another room, and was wondering if there is any kind of hookup i can use for
the 2 computers to share an internet connection with this cable. I can run
another line from router but didn't know if anything is available to use
other than that. Thanks for any help.

Plan B. Run that other line.

You connect the Router to your Internet modem. Then connect the
two computers to the Router. ( If you want a Gigabit LAN, connect
a Gigabit Switch to the Router, and the computers to the Switch.)

While that is the preferred way, it is not the only way.

The router should have a provision for connecting a hub. Find out from
the manufacturer. Then put a hub on the line in the other room and
connect the two PCs to it. Be sure to get a decent hub - full duplex
100BASE-TX.

It's not clear to me what you are trying to accomplish, or avoid. Are you
trying to avoid buying another cable (or other equipment), or are you trying
to avoid having two cables running between the rooms? Does the network
cable go through the wall using a wall jack, or does it go out the door and
down the hall?

If you are trying to avoid having two cables running between the rooms, one
thing that you could do is connect a hub to the network cable in the room
with the two computers and then use two shorter network cables to connect
the computers to the hub, or if the router supports wireless, you could get
a wireless card for one of the computers.

What you can do depends on what you have got, what you are willing to get,
and what you are trying to accomplish.

Assuming that you don't have a 3rd computer already connected directly there to
that router and assuming that the router is next to your cable/dsl modem, then
move your router to the other room with the 2 computers. Then connect the long
cable to the modem & router.

If he has only one network cable, how is he going to connect his two

I suggested a hub.

As you quoted him above you can see he said he "Could run another line" . A
hub would be an extreme answer to his question. He just didn't know what to
do with that other line. The easy answer is to use that one line to go from
the modem to the router when it has been placed in the same room as the
computers. Connecting another line from the router to the other computer. If
it is any hardware I would suggest a wireless router.

And how do you connect two computers to anything on a LAN? Including
a "hub",- with ethernet cables. With switches as cheap as they are, there
is
no good reason to use a "Hub". If the router is in the room with the
Internet
modem, then the OP should move the router to the room with the two
computers, then connect the one long run would be between the internet modem
and the router.
What is the difference between an Ethernet hub and switch?
Although hubs and switches both glue the PCs in a network together, a switch
is more expensive and a network built with switches is generally considered
faster than one built with hubs. Why?

When a hub receives a packet (chunk) of data (a frame in Ethernet lingo) at
one of its ports from a PC on the network, it transmits (repeats) the packet
to all of its ports and, thus, to all of the other PCs on the network. If
two or more PCs on the network try to send packets at the same time a
collision is said to occur. When that happens all of the PCs have to go
though a routine to resolve the conflict. The process is prescribed in the
Ethernet Carrier Sense Multiple Access with Collision Detection (CSMA/CD)
protocol. Each Ethernet Adapter has both a receiver and a transmitter. If
the adapters didn't have to listen with their receivers for collisions they
would be able to send data at the same time they are receiving it (full
duplex). Because they have to operate at half duplex (data flows one way
at a time) and a hub retransmits data from one PC to all of the PCs, the
maximum bandwidth is 100 Mhz and that bandwidth is shared by all of the PC's
connected to the hub. The result is when a person using a computer on a hub
downloads a large file or group of files from another computer the network
becomes congested. In a 10 Mhz 10Base-T network the affect is to slow the
network to nearly a crawl. The affect on a small, 100 Mbps (million bits
per scond), 5-port network is not as significant.





Two computers can be connected directly together in an Ethernet with a
crossover cable. A crossover cable doesn't have a collision problem. It
hardwires the Ethernet transmitter on one computer to the receiver on the
other. Most 100BASE-TX Ethernet Adapters can detect when listening for
collisions is not required with a process known as auto-negotiation and will
operate in a full duplex mode when it is permitted. The result is a
crossover cable doesn't have delays caused by collisions, data can be sent
in both directions simultaneously, the maximum available bandwidth is 200
Mbps, 100 Mbps each way, and there are no other PC's with which the
bandwidth must be shared.

An Ethernet switch automatically divides the network into multiple segments,
acts as a high-speed, selective bridge between the segments, and supports
simultaneous connections of multiple pairs of computers which don't compete
with other pairs of computers for network bandwidth. It accomplishes this
by maintaining a table of each destination address and its port. When the
switch receives a packet, it reads the destination address from the header
information in the packet, establishes a temporary connection between the
source and destination ports, sends the packet on its way, and then
terminates the connection.

Picture a switch as making multiple temporary crossover cable connections
between pairs of computers (the cables are actually straight-thru cables;
the crossover function is done inside the switch). High-speed electronics
in the switch automatically connect the end of one cable (source port) from
a sending computer to the end of another cable (destination port) going to
the receiving computer on a per packet basis. Multiple connections like
this can occur simultaneously. It's as simple as that. And like a crossover
cable between two PCs, PC's on an Ethernet switch do not share the
transmission media, do not experience collisions or have to listen for them,
can operate in a full-duplex mode, have bandwidth as high as 200 Mbps, 100
Mbps each way, and do not share this bandwidth with other PCs on the switch.
In short, a switch is "more better."

I do not understand your question. Linksys offers a 4 port switched
router where you can use one of the ports to connect a hub if you want
to expand the LAN to 5 or more machines. You then have 3 switched
ports and 1 port connected to a hub.

The issue is whether the router will permit addition of a switch. I do
know that some routers will allow the addition of a hub.
If the router is in the room with the Internet
modem, then the OP should move the router to the room with the two
computers, then connect the one long run would be between the internet modem
and the router.

That would be ideal if he could do it. But we don't know if he has
other computers connected to the router currently.

Actually, Linksys's 4 port router (BEFSR41, which is the one I use to
provide a hardware firewall for my LAN) has a WAN port [for connecting
to the Internet modem] an "Uplink" port [for connection to a Switch or Hub]
and four ports to connect Computers or other Networked devices. The
router can only operate upto 100Mbps, but it will "share" an Internet
connection (at 10Mbps) to upto 255 devices using the Uplink. I have a SMC
8508T 8port 10/100/1000 Mbps Switch, connected to the Uplink port and
everything else connects to that. This gives me a Gigabit LAN. Those
devices
with 1000Mbps capable Ethernet adapters (my computer MBs and a
"Terastation" NAS) can all communicate between each other 10 times faster
than they could on the router, all of them can access the Internet (at
10Mbps)
through the router and Internet modem [ it's the modem interface that limits
it
to 10Mbps.]

What that doesn't say is you give up one of the 4 switched ports to
make the Uplink connection. At least that's what was the case several
years ago.

He uses the Uplink for that single line going into the other room and
puts a hub/switch on it. That leaves 3 switched ports in the room
where he has the router now.

I am not claiming that is the only way to do it, only that it is the
quickest and cheapest. Hubs are typically cheaper than switches so I
recommended a hub, Unless you are playing games or doing a lot of
serious downloading (like bit torrents) you don't really need a
switch, although I am sure someone will find some arcane reason why it
is better to go with a switch other than those listed here.

You have a modem with more than one Ethernet connection? One
that can be directly wired to two computers? You would bypass
the router all together? I don't think your "by far best" solution is even

You mean from the router to the second computer. The modem is
connected to the router WAN input.

Some ISPs provide for 2 separate WAN connections. But I believe they
have a special modem or two modems.
