Title: Hook up internet on second computer
Post by: Magnum on November 20, 2010, 06:58:26 PM
My grandson likes using my old computer.

What would be the least expensive way of transferring the Internet temporarily to the other computer.

I use DSL.

If you have only one ethernet port in your router, you can buy a switch to serve more computers accessing the net.

Phone line goes from wall -> DSL modem -> Ethernet Port

Well it certainly could be just a DSL modem. I had one for many years, and had it plugged into a router. But in the UK they typically give you a combined ADSL/Router unit. Whether you need a router, a switch, or just a newer ADSL/Router will depend on what you have now, and whether you use PPPoE to log into your ISP. Pretty much whenever my folks talk to BT about renewing service there is a new modem/router/wireless/phone available for free to handle the new speeds being offered by default. Any router is going to provide multiple LAN ports out of the box.

So a couple of questions.

What is the Make/Model of you DSL Modem?

What does "IPCONFIG /all" report at the console?

Do you have any special log on, or application to get online? Anything special in Settings->Network Connections. Not your user/pass of course, just the mechanics of how you do things now.

ethernet cards (aka NIC - network interface card) are about the least expensive adapters made
i have seen them for as little as $10, new

There is no installed software by AT &T that is used to connect to the Internet.

Does the modem have ethernet and usb? Some older modems wouldn't let you use both at once (they shared the interface) but most will have an interface for both.
That means installing usb drivers from the modem disc onto the other computer.
Title: Re: Hook up internet on second computer
Post by: sinsi on November 21, 2010, 05:46:24 AM
Forget that, just looked up the specs. All you can do is swap the cable between computers (one computer at a time has internet) or buy a cheap 10/100 switch.
Title: Re: Hook up internet on second computer
Post by: Magnum on November 21, 2010, 05:46:33 AM
It only has an ethernet connection.

Is there an easier way other than getting a longer ethernet cable and running it to the other room?

I could just switch plugs.

Title: Re: Hook up internet on second computer
Post by: dedndave on November 21, 2010, 11:49:07 AM
you can google SNMP  :P
Title: Re: Hook up internet on second computer
Post by: Magnum on November 21, 2010, 12:21:29 PM
Thanks for the help guys, but I need to clarify the logistics.

"Dumpster special" is in my living room.(which is near the phone plug)

"P-3 special" is in my bedroom.

I don't have room to have both computers in the same room.

Verstehst du?





Title: Re: Hook up internet on second computer
Post by: dedndave on November 21, 2010, 01:05:41 PM
like i said - SNMP is one way to go
you can connect the computers together (parallel or serial port) and share the connection
it isn't great, but it will do the job inexpensively
there is a limit to cable length - you won't get very far with parallel
with serial, i think it's 100', if memory serves

the other way to go - costs a little more - get a router
it doesn't need to be a wireless router, if you can run an ethernet cable (from router to p3 machine)
if you go with a wireless router, you will also have to purchase a wireless adapter for one of the machines
one machine may be connected directly to the router
with a wireless router, you typically get one hardwire connection port

i doubt you will be able to find a wireless adapter card that will work in the p3 machine, or with anything less than XP (perhaps win2k)
on the bright side, if you get a laptop sometime in the future, you are good to go

Hi,

   My parents have (had) two computers in different rooms.
I got a WiFi router and a WiFi NIC card for the second
computer.

DSL => Router => Cable => First computer
              => WiFi  => Second computer

   Also works with the laptops my siblings use, a possible
bonus.

Regards,

Steve N.

The IP address of 192.168.1.1 and 192.168.1.100 are basically "local" network addresses assigned by the modem, and you are using OpenDNS for DNS lookup.

The modem supports DHCP and acts as a gateway. It should serve up local IP addresses for any/all computers you attach.

Solution 1) Get a longer cable to reach where you want to get. Switch cables.

Solution 2) Get a couple of cables, and a cheap 5 or 8 port switch/hub. Connect modem, computer1 and computer2 into the switch.

Solution 3) See if AT&T will spring for a newer "2-Wire" brand modem/wireless router. If you've had your contract for a while they might give you one free. You have to configure your user/pass into the PPPoE settings of the modem/router. Get some wireless cards/dongles, and you're up without dragging wires about. Good if you're in an apartment and you can't drill holes in walls/floors. These wireless boxes are prolific in AT&T's Illinois market, although they only use WEP encryption. If AT&T won't give you a free one, they are on eBay all the time.

I don't need any fancy wirestuff stuff.

I'll see what kind of cabling I need, etc.

With no job and my home repair business way down, fabrication and "material recovery" are the order of the day.

Ethernet cables and ADSL modems/routers show up at the local thrift stores around here. The dumpster method at apartments at month's end might also work.

Hi,

   The WiFi stuff was not all that expensive.  The router was
sixty odd dollars.  The NIC for the old Win98 machine was
twenty something.  It was brand name stuff (D-Link?) from
Office Depot a few years ago I think.

Thanks a lot.

I am a long time customer of AT&T, will try solution 3 first to see if I can get it for free for later use.

I'll use solution #1 and get or make  a switch.
I think it's CAT5 I'll need.

I have a friend in Austin who send me some parts to fix my blinking tail light, maybe he can show me how
to make a switch if I have to.

Have a great day,

Magnum,

Make a switch?  No offense, but I don't think so.

If AT&T won't give you a router then get a long Cat5 cable and either manually switch the cables or find a cheap 10/100 BASE-T switch.

Tab A...
...Slot B

instead of a switch (8 poles i think) just buy a few connectors
it is almost as easy to unplug from one hole and plug into another as it is to flip a switch  :P
i have seen 8 pole mini-toggle switches, and they're not really that expensive
but it was in an industrial circumstance, where they get the good prices
soldering to 24 pins on a mini-toggle is a task best left to someone that knows how to solder, too

if you buy it at radio shack or something, they'd probably charge you an arm and 2 legs
you might find one at a ham radio swap meet or something for a few bucks, though
maybe even online, if you look hard enough

here is a rotary switch ~$15 - that includes the knob   :P
http://www.advancemcs.com/?contentID=45&merchGroupID=55&merchID=324

the 8 wires are grouped in 4 twisted pairs
it is good to keep pairs together, maintaining the twist to as near the switch as practical
a twisted pair actually forms a balanced, low impedance transmission line
i am guessing they use 75 ohm differential line drivers/receivers at both ends

Does this look like it would work?

Andy,

The trick if you can hunt around for some second hand stuff is a 10/100 mbit hub and some ethernet cable. You can run ethernet cat5e up to about 100 metres with no great loss of speed. Plug the output from your router into the input side of the hub and take both machines off the output side. You need PATCH cables for a hub, not twist cable that get used between two machines.

Thanks Hutch.

I have been visiting some computer repair stores as part of my job search.

One store I went to yesterday, had boo-koos of used parts.

I will add your recommended items to my list.
