Help911, usually, with no TCP/IP internet connection such as through a DSL modem and/or router, you can connect 2 pcs together using a cross-over CAT5 RJ45 cable or a hub with an uplink port to connect a non cross-over CAT5 cable.A pre-made CAT5 cross-over cable is much easier to use (and buy, too, rather than making it yourself), which you can easily buy at your local computer store. And it's pretty INexpensive, too. ;)

I would like to connect my LAptop to my Desktop at home.I know we should use a cross-over cable to connect the Ethernet ports. But i have no clue as to what are the steps / procees i should follow to mak this connection happen.I would like to have the step by step procedure as what is to be done in each of the units to connect the PC to Laptp.If ther is any website which tells the same pls direct me to the same.
hi ,usually in cat5E cable there are four pairs of cable.colours are as follows:(orange & white orange)(brown & white brown)(green & white green)(blue & white blue)take the rj45 connector and the splice one end of cat5 cable insert into the connector according to the colour code given below either from left to right or from right to left.1)white orange2)orange3)white green4) blue5)white blue6)green7) white brown8) brownwith the other spliced end of the cable ,just interchange the cable connections i.e1)white green2)green3)white orange4)blue5)white blue6)orange7)white brown8)brownnow ur cross cable is ready to transfer data and communicate between two pc's without any modem or hub or any wirless communication device.

go to radio shack and purchase a cross-over cable (they shouldn't be more than about $10 for a simple 5' cable. if you know how to SOHO network a few compputers to a hub, then the idea is the same except you are not using a hub and you are limited to just two computers. connect the two computers and decide which will be the gateway, run the netwoprk setup wizard on that first and it should be assigned the 192.168.0.1 automatically, if not the r click the network icon and choose properties and manually set it's address as such, and subnet should read the default 255.255.255.0 and the gateway will read back to itself if you input 192.168.0.1 after that is done then you do the same with the other computer but make sure the address is 192.168.0.2 and reads from the gateway of 192.168.0.1 if you are using ME or other then you might have to input the name of the computer for the gateway, xp won't ask you that. if you have any firewalls, you might want to manuall;y configure to allow for the two IPs (192.168.0.1 & 192.168.0.2) if you still have trouble check your firewall setting for trusted zones (networked computers not internet zones) and also check your internet options securities. if you still get problems then email at: communications@sunbeach.net and I will walk you through it. I like to build my own cat5 but if you are not used to doing it often with success you are better off buying one that is professionally made so that you know that your problems with connecting are not because you messed up on the rj45 plug.YWAM Barbados
