My network works perfectly well with this computer on windows 7, and with various other computers and devices. I installed Ubuntu 14.04 today, and it works perfectly, except for the wifi.
When I try to connect (wifi icon, name_of_network), a popup asking for the password keeps appearing every minute or so, and it does not connect. The password is correct.
I tried to delete the network from the connection list (wifi icon, edit connections), restart my computer and try again, to no avail.
Ethernet works perfectly.
I have to assume that it is related to Ubuntu, since the wireless card is recognized and can scan the different networks available.

I do not know Ubuntu 14.04 well enough to even try anything.
