View Full Version : [ubuntu] Internet at school

December 4th, 2008, 02:40 PM
Hello there,

Sorry if this has been in countless posts, but I just couldn't find anything that solves my problem.

Anyway, my problem is that I can't connect to my wireless at school. It works fine where ever I try but there. What it does is that it finds the Connection, tries to connect to it, both bubbles go green, and then it just disconnects after giving up trying to get an address. I've pretty much tried everything I can come up with, which basically is just creating a new connection type, set the IP Gateway DNS etc, but it still just wont work.

I am using 8.1 and my Network controller: Intel Corporation Wireless WiFi Link 5100

Thanks for any help provided

Do you need any special permissions from the school, passwords etc to enable a connection.

Should imagine that you need to be at the school,
From what i have heard from friends who are uni the wireless signals are allways rubbish so if you have even the smallest error it can cause problems.

some schools are moving to certificates for wireless access, which will require more effort on your part, or they may have purposely disabled non-windows machines with nac and cisco clean access. you need to open a helpdesk ticket with your school and get with the network guys to find out the problem.

well what you could do , is setup static ip when connecting to school network.. set those ips in the /etc/network/interfaces file.. it seems to connect to the network but not get an ip.. so then you specify the iop
