I have an existing home network which consisted of a desktop running Windows XP, hooked via cat 5 to my combination Speedstream router /gateway, and a Windows XP laptop that connected wirelessly to the same router. The computers recognized each other, were interactive and connected to the internet (DSL is my only choice here).
I recently added a Windows Vista computer to the mix (wired/cat 5) and upgraded the laptop to Vista as well. (3 computers now) The wireless laptop recognizes the Vista desktop and they both connect to the router and the internet. The XP desktop connects to the router and the internet, too. The Vista machines and the XP machines do not recognize each other.
In other words, when looking at the network from the Vista machines, they both show up, as well as, the router. In the XP machine only it and the router are there. At the moment my network is unencrypted. Any ideas why they aren't one big happy family and how to fix it? Thanks.
