I have upgraded from mint 17.3 to mint 18, and now I experience irritating wifi problems, which are (probably) connected to the power management.
Before the upgrade, I had set it off in the /etc/pm/power.d/wireless
file (sudo chmod +x), like:
#!/bin/sh
/sbin/iwconfig wlan0 power off
And it just worked.
Now, Mint 18 ignores these settings. Also, the wlan0
was changed to wlp2s0
.
But the worst part is, even if I set the power management off in the console, I can still feel the connection is disgustingly slow, and there are constant gaps. The only way to fix that is to reset wifi... every few minutes.
This is the iwconfig
output, where the power management is clearly off, but I have no internet conection:
$ iwconfig
lo no wireless extensions.
enp3s0 no wireless extensions.

Any help? If this problem persists, I will have to change the distro after 2 years, because working with a starving wifi card is kind of complicated.
