I've 2 PCs in my house both connected to a LAN switch (Encore ENH905-NWY). Both the PCs have Windows 7 Ultimate x64 installed. One has Realtek RTL8168B and another Realtek RTL8168C. I'm not a networking person and have less knowledge on networking, LAN, internet. When I switch on the LAN Switch device, it shows that both the wires are connected properly. Then I get the network sign with a yellow triangle on it. Then I click it and managed to change the IP, subnet and default gateway somehow. IP in one PC is 192.168.2.1 and the other has 192.168.2.2. Both have subnet 255.255.255.0 and default gateway 192.168.2.5. But I get the Unidentified Network. The ping works and we can even chat and send files from VyPress Chat. Remote Desktop connection also works. But I don't know how to share files like I used to do it in XP. (Just copy contents to the shared folder). I just want to enable the LAN for LAN multiplayer gaming, file sharing + transfer and voice chat. I don't want internet connection because I've a USB modem which does the work. But when I connect to the internet through the modem, the LAN connection goes out. I don't want this to happen. I've recently installed the driver on one of the PCs and still get the unidentified network (public network). I've a game (Armagetron Advanced) which I can play with LAN. If I open a server in PC1, PC2 can see it but if I open the server in PC2, PC1 can't see. I need help, please.
