Windows 7: 2 wire 2700 modem and network

2 wire 2700 modem and network

Can I start a home network between a Win 7 and a XP laptop through an at&t 2wire 2700 modem without using a router??? I have been trying unsuccessfully for 3 days now. I am not a real novice but I do need specific instructions.

There are two ways I know of to create a network without a router/switch. They are both types of network bridges.

One is a ethernet bridge. You need an ethernet port on the desktop and laptop, and you need to connect the two together. You also need a secondary connection on one or the other so that you can access the modem. Considering how you only have a modem, this is probably not your best option unless you have two ethernet connections on the desktop. You could also use this method using the desktop connected to the modem via ethernet and the desktop broadcasting to the laptop via wireless but connectify makes that same process easier.

The other option is using a program called Connectify. It allows you to share an internet connection (wired or wireless) through your wireless card even if you're using that wireless card to connect to the internet. This method requires one computer to be connected to an internet source and both computers to have wireless cards. The computer connected to the modem broadcasts the signal using it's wireless card.

In order to instruct you properly I need to know what types of connections you have available on each computer and how you connect to your modem. If you're using ethernet to connect to the modem and have a wireless card in both the desktop and laptop then it should be fairly easy. All you need to do is use the ethernet on the desktop to connect to the modem and then use the desktop's wireless to broadcast that signal to the laptop. This can be done either through a traditional wireless ad-hoc network or using connectify.

How to create an ad-hoc network
-- Connect to modem using Ethernet
-- Network computers using Wireless on both sides
-- Needs Ethernet and Wireless on Source Computer
-- Bridge connection must be wireless

-- Connect to modem using Ethernet or Wireless
-- Network computers using Wireless on both sides
-- Only needs one connection on each computer if using wireless.

Create a Network Bridge
-- Connect to modem using ethernet/wireless
-- Network computers using Ethernet on both sides
-- Needs two separate connections on source computer
-- Bridge connection must be ethernet

Windows 7

tried ad hoc network but it did not work. All seemed good til I went to connect. XP would connect to ad hoc network but win 7 would connect to network but not to XP. Also had no connection to internet.
I have wireless network adapters in both laptops. Normally I connect to internet wirelessly through both computers seperately. I would like to access files in win7 with the xp which is a netbook.
