I'll try and give as much info as possible to reduce the amount of unnecessary questions and wasted time. I am extremely frustrated and at the point of pulling out my hair. I used to have my windows XP Home Service Pack 3 desktop connected to my Toshiba Satellite laptop running Windows 7 via a crossover ethernet cable. This is how I accessed the internet on my desktop. Setting this up initially was no problem. Recently, I formatted and reinstalled Windows XP on the desktop (hadn't been done in a few years, clogged, slow, needed to be done). Since then, I've tried to do the same connection I had before with a crossover ethernet cable from my laptop to my desktop. No luck. No settings on my laptop have changed since the format & reinstall of windows XP on my desktop. I have checked all the settings, including file sharing, windows firewall (on, off, exceptions allowed), file folder sharing, network discovery, etc. All are set to on besides windows firewall (exceptions allowed). I tried deleting and recreating the network bridge between the LAN and Wireless network multiple times to no avail. I've tried multiple different IP addresses and default gateways, nothing works. Before you jump to any conclusions, I used this as my guide: http://www.wikihow.com/Bridge-an-Internet-Connection My laptop has internet and works perfectly fine. My desktop, in network connections, has one LAN or High-Speed Internet connection labeled 1394 Connection. File and printer sharing is turned on, and I manually put in the ICP/TCP settings here but no luck either. Something interesting is no matter what I do, under 1394 connection status support tab, the address type, IP address, subnet mask and default gateway are all blank. Clicking "repair" immediately yields a message "Failed to query TCP/IP settings of the connection. Cannot proceed." At this point I am guessing some driver needs to be updated or something like that? It is important to note that I have not installed ANYTHING on my desktop since reinstalling windows. It is not running any anti virus software. I have not been connected to the internet for a single second since reinstalling windows XP. Any and all help will be greatly appreciated, thank you!
