Hi,Hoping someone can help. I have 2 laptops and a wireless internet router.Laptop 1 is a Win 7 machine, from which I am sharing files to Laptop 2 (XP). Originally I created a homegroup and shared wirelessly, but the connection was too slow, so now I have connected the two Laptops via cross-over cable and the speed is much better. Here is my problem...LAN and wireless internet seem to work in a mutually exclusive way on the XP machine. To connect the XP machine to my Win7 machine via LAN crossover I have to disconnect the wireless connection on the XP machine, otherwise the LAN connection does not work (e.g. the software on the XP machine - Quickbooks - cannot see the shared file on the Win7 machine). Likewise to use the wireless internet on the XP machine, I have to disable the LAN on the XP machine.If I turn on both wireless and LAN connection on the XP machine neither one (Wireless or Lan) will connect succesfully on the XP machine.I am not trying to share internet access from the Win 7 machine via LAN, just the shared files on the WIn 7 machine. I want the XP machine to have it's own wireless internet connection, and to see the shared files on the Win7 machine at the same time.The Win 7 machine however is able to connect to both seamlessly.Any ideas?ThanksLee1 person needs an answerI do too

Hi lmorse, Its impossible to know exactly what the issue is without more information, but I have a guess. When I've seen similar problems it usually been because of conflicts between the subnets on the two connections. What is being used for the IP addresses on the crossover connections?If you can run ipconfig on the XP machine while both connections are active and post the output back here that should help us nail down the issue. You can runcmd /c ipconfig/all >"%USERPROFILE%\Desktop\ipconfig.txt and then open the file ipconfig.txt that will get created on your desktop. This file will contain the output of the ipconfig command, which you can then copy and paste back here.-z1p

HiYou cannot use two Network cards in the same computer on the same network working at the same time.Configure the Crossover connection with Static IP of a Different subnet than the Router's Network.In the crossover Network, make sure that in the TCP/IPv4 properties the File & Printer Sharing ischecked.In the Wireless TCP/IPv4 properties, uncheck the File and printer sharing.On SubnetClassical IP looks like this (example), 192.168.1 .x The first three groups are also called Subnet , and they identify the specific Network, x can be a number from 0 to 255 and it identifies each unique device on the Network. An IP of 192.168.2 .x would be a Subnet of another Network. Jack-MVP Windows Networking. WWW.EZLAN.NET
