problems with crossover cable and 1000mbit connection

hey guys. im having trouble networking my machines.

I have my main machine connected to a 100mbit router. it has a second network card which i want to use a crossover cable to connect to my backup computer. i want to use a crossover cable so i can connect these at a 1000mbit connection speed, so i cant just bridge the connections, or the speed gets limited to 100mbit.

however, when i try to connect these two machines with a crossover cable, "i get limited or no connectivity"

does anyone know how i can work around this?
thanks for any help!

 

EDIT: NM, I didn't read your post closely enough -- you are getting a physical connection. IP, touche.

A standard Ethernet crossover will not work because GigE requires all 4 pairs of wires, while Ethernet requires only 2. You will need to purchase or create a GigE cross-over cable:

Pin Connector #1
1 white/orange
2 orange
3 white/green
4 blue
5 white/blue
6 green
7 white/brown
8 brown

Pin Connector #2
1 white/green
2 green
3 white/orange
4 white/brown
5 brown
6 orange
7 blue
8 white/blue

 

You need to set a fixed IP address. If you aren't sure how to do this, just say what the OSs are on the PCs you are trying to connect.

 

any cat 5e rate cable shound be good

you sure both you laptop have giga-byte lan?

 

thanks for the help guys. yes they both have gigabit lan. im using windows xp.

 

The way I remember setting fixed IPs (haven't used an XP machine for a while now), is by:

*Right click on 'My Network Places' and opening properties (opens list of connections)
*Opening the Properties of the network connection
*Going to the properties of TCP/IP
*Entering an IP address such as 192.168.1.x

Once this is entered on both of the PCs (remember that the last number must be different on each PC, and the first three the same), the network should go fine.

Hope this helps

PS. I hope I didn't over simplify the instructions, I just don't know how familiar you are with networking.

 

thats ok. well i've tried to do that, but as soon as i do the network connection drops out to my router.

on network card a i hace dhcp and the followring settings are aquired-
ip 192.168.0.134
subnet 255.255.255.0
default gateway 192.168.0.1

on the other network card (which connects with the crossover cable) i have an alternate manual config set to this-
ip 192.168.0.135
subnet 255.255.255.0
gateway 192.168.0.2

 

GigE does not require a crossover cable. So gige to gige std cable, it's partof the gige spec. It will auto config. 100/10BaseT does.

Connect to the router 1st. Then set the wired port to bridge. Then make the connection.

 

It's not at all part of the "spec", its just that many devices do that.

 

sorry blue68f100, but i dont quite follow you. i can't just bridge the two network cards because when i do that the speed goes down to 100mb/s.

 

This doesn't work because you have two paths to the 192.168.0.x network on the first computer . . . what you will probably need to do is set the 2nd card to a different network like 192.168.1.x and setup Internet Connection Sharing. Set the other computer to DHCP. The double NAT shouldn't be a problem.
