I have two PCs in the house, both Windows XP. The main PC has the router wired to it and the second has the wireless connection. I have lost the broadband on the main PC although the second PC is OK. (I'm using it now)
On the main PC when opening IE it blames firewall settings. HTTP port 80, HTTPS port 443and FTP port 21, which doesn't mean anything to me. I have tried switching off the firewall but it makes no difference.
When checking on network connections, it shows '1394 connected, firewalled' and 'Local area connected, firewalled'. The LAN shows activity, but the 1394 shows no activity.
The 1394 connection shows, 'status-connected, speed-400 mbps'. When I click on 'repair' I get 'cannot proceed, TCP/IP not enabled. Contact person who manages network'.
The 1394 net adapter is shown as working properly and the Internet Protocol (TCP/IP) box is ticked, but if I select this and click 'install' I get 'unable to find any drivers for this device'.
Can anyone tell me how to sort this out. Have I really lost drivers or is this a 'red herring'.

is your router connected using ethernet or firewire port

1394 is a Firewire port, not what you are using to connect to the internet. You are using Ethernet which is 'Local area connection', so forget about 1394. Let's get some information.

Click on Start then Run and paste the following into the Run box, exactly as show, including double quotes:

cmd /c "ipconfig /all > postme.txt & ping yahoo.com >> postme.txt & notepad postme.txt & del postme.txt"

and press ENTER.
