networking - Ubuntu 14.04: Public Wireless Will Not Connect




I've checked other and older solutions around the web for wireless issues on Ubuntu 14.04 and a couple solutions here. My problem appears to be either unique or a fluke.



I can connect to the wireless network at home, no problem. But when I'm at school, I can only see available networks -- I cannot connect to them. I open the Network settings, pick a network and try to "Connect" or even use the "Settings" option. Clicking neither button does anything at all. No pop-ups, no windows, no prompts for password. I click and nothing happens. I can see all the available networks, their signal strength, and whether they're secure. I cannot connect to them.



I tried rebooting. I tried downloading various updated drivers via Terminal. This problem only happens at school. I am typing this message at home, connected wirelessly to my router. No issues. It's worth noting I can run Windows at school and connect to the wireless network. School primarily uses Macs, so I don't know if that makes a difference with the routers they're using.



My computer info: Toshiba Laptop -- I'm running Windows 7 64 bit and Ubuntu 14.04 64 bit (full OSes) on this laptop.



I ran the wireless script suggested here from home. The results: http://pastebin.ubuntu.com/9065947/




UPDATE:
Wireless data from the location where I can't connect: http://paste.ubuntu.com/9336368/



All help appreciated. Thanks.



EDITED: Corrections.



I have an answer, but I'm still not sure why this was even a problem. Please see the original post for a detailed description of the precise problem.




In the end instead of connecting from the Network panel as usual, I typed in the command:



nmcli d wifi connect YOUR_NETWORK password YOUR_NETWORK_PASSWORD iface wlan0


The command line was the only option for me. I'm actually surprised no one suggested this simple step, but here it is for posterity! Thanks to everyone who pitched in and clued me in to where to look for issues.
