I have some troubles with the internet connection on my laptop. All the devices can easily connect to wi-fi while my laptop with Ubuntu 14.04 can not connect or it gets the connection, but for some reason the internet is very slow. This behavior can't be observed with other devices.
My computer kept switching the wi-fi on and off, that is why I have created this script, which I load when I turn on my computer:
#!/bin/sh
/sbin/iwconfig wlan0 power off
However, it didn't resolve my problem. So what could be the reasons of such behavior?
iwconfig wlan0 command output
