Hello,
installed 14.04 LTS, upgraded kernel to 4.0.4 (since there was some issues with 3.x kernel and ASUS X550 touchpads).
I've got an BCM43142, installed "bcmwl-kernel-source_6.30.223.248" deb file, since the current one from apt repository
doesn't work with 4.0.4 kernel :/
However, can't connect to my home wifi, just keeps asking for password.
It's WPA2-PSK but, NetworkManager shows WPA-PSK on it, and when expanding it, shows correct one WPA2-PSK.
I guess this shouldn't be odd, but i saw another wifi network with WPA2-PSK in netman, without expanding it.
Well, this isn't a problem(i guess), because i switched security off in router just to check, and still - it can't connect.
Just tries to connect and it disconnects when timeout comes.
Noticed kinda strange thing in my router's dd-wrt main page, where it shows all connected clients - at second, new
client joins on ath0(thats 2.4GHz wifi) and immediately disconnects.
Some cutout from syslog:
Thanks for any suggestions
