I have a small network with two laptops connected to the Internet. The building has a T1 for access and the two laptops are connected through a Linksys router. One of the laptops can connect to the Internet from both the classroom and the office ethernet drops. The other laptop can connect only from the office drop. It can not connect from the classroom drop. I've been to the site and my laptop can connect from both the classroom and the office drop. I also had a local wiring contractor out to test the drops and cables. Everythings fine there. I did a DNS flush on the laptop that can connect only from the office drop. That didn't work. Any suggestions? I'm getting ready to rebuild the laptop just to get this thing working again.
