Unstable Wifi Connection Ubuntu 14.04

Solution 1:

I suggest you try a driver parameter. Please open a terminal and do:

sudo -i
echo "options rtl8723be fwlps=0"  >  /etc/modprobe.d/rtl8723be.conf
modprobe -r rtl8723be
modprobe rtl8723be
exit

It may take a reboot. Any improvement?

I added the following lines in /etc/modprobe.d/iwlwifi.conf:

options iwlwifi 11n_disable=1

options iwlwifi swcrypto=1

and the bug is gone!
