I upgraded yesterday from xUbuntu 14.04 to 14.10, because I hoped to have better bluetooth recognition. (I didn't).
Before the upgrade
Wifi would drop out seemingly randomly. More often, when there was more space/stuff between me and my router, but also when nothing changed.
Time could be between 2 days and (in extreme cases) a few minutes.
I need to disable-enable the whole network by using the dropdown menu, because after losing connection the SSID of the router is not in the menu for me to choose. The router itself does not lose connection to any other device and I'm connected to it again after 5 seconds, after re-enabling the network.
After the upgrade
Wifi drops out faster now ~10-30 minutes.
I already tried this solution. But it didn't work.

Any further information will be gladly provided. I would be very grateful for some help and even a little explanation what the problem is if possible.
Update 1
Jan 24 17:21:37 Laptop kernel: [ 7755.037954] wlan0: deauthenticated from xx:xx:xx:xx:xx:xx (Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA)
This line appears everytime my connection drops. Might be connected with this bug
Update 2
For the time being, I made a script automatically reconnecting me.
#!/bin/bash
while :
do
if ! ping -c 1 -W 4 192.168.2.1 >/dev/null; then
notify-send 'Network gone down' 'Reconnecting...'
nmcli nm enable false;
sleep 0.5;
nmcli nm enable true;
sleep 10
fi
sleep 1
done
IP address might need to be changed. I'm not fit in networking. It may also produce some false positives. It is a hack, after all. Still better than manually clicking through menus every time.
Update 3

Cross posted the question to the ubuntu forums as adviced.
