Computer networking dillema?

Question

i am networking two computers in my house. i want them connected in such a way that they will share 1 internet connection. when i plug in the cable. my compter tells me that the network cable in unplugged when after many times i double-checked, it isclearly plugged in. i put in a new networking card. but yet the same problem exists. the computer says the network cable is unplugged when i know it isn't unplugged. please help.

ok, from what i see posted below, i am using a crossover cable. so i used a router and now the connection problem is gone. now i tried share an internet connection between computers, and once i allow it, the host computer can't sign on to the internet. any ideas?

Answer 1

you need the other type of cable (twisted type, I think). If you use a switch or router to connect your computers it should be fine.

Answer 2

What is the other end plugged into? If you are sharing an internet connection, I will assume it is broadband of some sort. You need to get a broadband router. Make sure you are using straight through cables, and not crossover.

Answer 3

If you're connecting two machines directly you need to use a crossover cable. A regular straight through cable will do exactly what you are experiencing.

A far better way would be to get a cheap SOHO router and just hook both machies up to the router's LAN ports. That way you only need one NIC in each machine and can use normal straight through cables.

Answer 4

You are either using a cross over cable and need a straight through or the other way around.
If either of your computers have a 10/100/1gb lan then it most likely is auto detecting and either cable should work.
If you are connecting both to a hub or router then straight throughs should be the ones to use. Again any of the equipment in the network MAY be auto detecting for wiring but it sounds like it is not.

As it sounds like your lans cannot autodetect then you have the following options.
PC to PC with a cross over cable.
PC to Router/HUB to PC with 2x straight throughs.

Answer 5

where did you get the cables from? Are they home made? or store bought CAT5 RJ45? If you made them, check to make sure they are color coded as ones from the factory. Try the cable else where, so you know the connection is good and replace the cables.
Modern routers will can tell if your cable is good, you will see the lights blink when connected.

It sounds like a cable problem to me.

Answer 6

If you have a cross-over cable then go to DEVICE MANAGER (control panel - system - on the tab HARDWARE - then DEVICE MANAGER) now in the list look for the network card under NETWORK ADAPTERS, make sure it is has no problems, u may see a red or yellow mark on it- double click and in the device status it will tell you the status. If it is disabled then you need to enable it, under DEVICE USAGE. if this all looks ok and it is enabled and says the device is working properly then ONLY then delete it from the list. highlight it and hit the DELETE button, then scan for hardware changes (the icon that looks like a monitor with a magnifying glass on it). It will then detect it again and you may need to insert its disk if asked. Restart computer before trying again.

Answer 7

If you want to connect two computers directly (without any device such a switch, or router) you must use a cross-over cable.

Answer 8

your problem is not so hard .
if you can chak your network cable that is posible that your network cable was realy not in a good condition.
