I have turned off power management for my wireless. I did that in /etc/pm/power.d/wireless.

When I try to connect to a network, the power management turns back on. So the connection fails.

I try:

sudo iwconfig wlan0 power off

The power management is then off, but when I connect it is turned back on.

I added a service as detailed here, it is now initially off. When I try to connect, the power management turns on again.

Output of lshw -C network:

What is happening here? Can I try anything else?

Hooks in /etc/pm/ are ignored in Ubuntu 15.04. Instead you have to create systemd services and enable them.

Although first try adding 

sleep 10
iwconfig wlan1 power off
exit 0

to your /etc/rc.local file. This should turn of power management at boot and might help with the connection. To permanently disable the power management look here.

More info about hooks in /etc/pm not working anymore here. To create systemd services have a look at ArchWiki.

Hope this helps.

This had nothing to do with Ubuntu.

My ISP, which also handles my wifi, blocked it because I did not pay in time.
