1. I recently bought a pc to pc hub cable and connected it both to my computer upstairs and the one downstairs. but the network folder said that the lan connection was still unplugged or not connected. it may be because of one of my network adaptors or just because one of the computers is old and fails at most things it tries. 2. Also i tried to connect my ''good'' computer to my broadband modem using the same pc to pc lead as it looks exactly the same as the lead i got with the modem just longer (the modem does take usb but my computer is to far away to use a usb cable so i went with the lan), but after it didnt work i looked up to see if there were different types of lan cables and found many different words coming up a few times like ''crossover cable'' ''switch cable'' and a few others. which lead do i need to connect from my computer to the broadband modem? Any ideas would be helpful!
