Hi, I'm having a problem with one of my PC's LAN setup, I have a broadband modem and a router that is connected to 2 MACs and 2 PCs. I recently formatted one of my PC, and I couldn't get my internet connection back or file sharing with other computers. It has "1394 Connections" written under Network Connections>LAN or High-speed Internet. I have totally no idea what it means. My other PCs has "LAN connections" written in the network connections folder and works fine. I thought this might have to do with the modem. The PC is able to connect through cable or wireless. I tried the setup home office network, it still doesn't work. Could anyone please help? Thanks, Martin. PSlease use words that I understand, I'm not that advanced in computer field.
