WiFi inestable en Lenovo T440p usando Ubuntu 14.10

Así que, básicamente, he malgastado los dos últimos días en intentar averiguar cómo estabilizar mi conexión WiFi. Ethernet funciona perfectamente bien, pero cuando intento conectarme a mi red inalámbrica, mi portátil se mantiene conectado durante unos 10 segundos, después de lo cual queda atrapado en un miserable bucle de conexión-desconexión. Se agradecerían mucho los consejos.

La salida del script inalámbrico es la siguiente:

Dado que los módulos se encuentran en el directorio de preparación, es probable que se trate de versiones tempranas. Yo probaría con los backports

sudo apt-get install build-essential linux-headers-generic
wget -N -t 5 -T 10 https://www.kernel.org/pub/linux/kernel/projects/backports/stable/v3.19-rc1/backports-3.19-rc1-1.tar.xz
tar -xf backports-3.19-rc1-1.tar.xz
cd ~/backports-3.19-rc1-1
make defconfig-rtlwifi
make
sudo make install
