PLEASE HELP FOR ROUTER...

I just installed a linksys router on one computer using Windows Xp. I am
running ethernet cable to my other computer running Windows ME. If the cable
is connected the the ME computer and I start it up, Explorer freezes. I have
to CTL, ALT, DLT to end Explorer. I can then use it again for a few more
seconds until it freezes. If I start the computer w/out the cable
connection, it starts and runs fine. I can put plug the cable in and connect
to the internet but each time I click to a new pages, it freezes again and I
have to go through the whole process. It does not close down the internet
window I am using but it allows me the nxt page and freezes again! Argh!
What the heck is happening??? Please if anyone can help, let me know!
