I really need to establish Internet connection sharing on my network but I'm really stuck. Here's the situation. My current ISP is really acting up lately, so I'm trying to use a Verizon USB modem. My main computer runs Windows 7, but for some reason I cannot get the modem or the software to work properly. It really conflicts with other critical software programs. I also have a laptop which runs Windows XP Pro, and the modem works perfectly fine on that system. What I need to do is configure the laptop so that it will allow its connection to be shared, and then to be able to connect my Windows 7 desktop to it. I can only seem to find information about a network where all the computers are either running Windows XP or 7, or where the host computer runs Windows 7 and the client is Windows XP. My situation is the opposite of that. Any suggestions?
