I hope it is okay to use this thread for other issues with the Intel Cnetrino Ultimate-N 6300
I created all the config-files as suggested in this thread. My problem is not the speed (internet is way slower then 10mb/s)
but the fact that the wifi stops working after a short while, no packages seem to come through. turning the wifi on and of makes it work for a while again. I assume it is some kind of powersafe mode doing the wrong thing. Any ideas on how to fix this?

My WiFi speed doubled using this modifications

Dear beachboy2,

thank You for your advice! It helped me to improve my WiFi on Ubuntu 16.04. It was not bad, around 70-100 Mbps, but it was 30-40% faster on windows 10. Applying your "patch" the speed doubled, now it is around 200 Mbps.

Thanks a lot!

zentai,

Glad to be of service!

7 years on and the "Slow WiFi on Intel Centrino Ultimate-N 6300" is still a topic of conversation!

Amazing.

As with several other settings on computers and computer components, this is a classic example of a manufacturer deciding that OFF is a sensible default choice and leaving consumers baffled.

Some would describe this, very generously, as counter-intuitive.

Others would describe it as plain stupid.

Just to add that the first 3 commands on post #2 can be replaced with the following, since gksu is deprecated:

Code:

sudo apt update

Code:

sudo apt install gedit

Code:

sudo gedit /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
