After a lot of r&d, I had finally got my home desktop (which runs Windows XP) and my new laptop (Windows Vista) sharing my BSNL DataOne connection on a Type 1 modem. I had connected the desktop to the modem using USB, since the USB drivers don't seem to work with Vista. The laptop was connected through the Ethernet cable. Everything seemed to work fine and I was able to access the internet on either or both of the computers simultaneously.Then, yesterday I goofed up while trying to connect the two computers using a crossover cable. Both computers suggested changes to network settings and went ahead and made those. I was never able to get them to connect and share files, but on the flip side, the internet stopped working on both.I've since been able to restore the internet connection on the desktop as it was (PPPOE setting in the router with the username and password entered inside it, so I do not have to dial in), but the laptop just won't connect. I think the problem is that it now shows an "unidentified network" between the computer and the internet in it's "Network Sharing Center", whereas it used to just show the computer connecting the internet earlier. I'm not able to get rid of the network in between!Sorry for the long post, but I thought I should provide as much detail as possible so you guys can point me in the right direction. Any help will be greatly appreciated.
