My mother works for a school district in Colorado and I setup 60 of their Dell Latitude 2100 netbooks for wireless printing and all of them took the info except for three. These three would not connect to the wireless network of the school. They all have the right drivers and are all currently running gnome version 2.26.1. All the other laptops are running smoothly and there are no issues, any help or advice would be very much appreciated.
