I've been having wifi connectivity issues, and I've narrowed the problem down. Wifi power management seems to mess with my connectivity. I can turn it off with:
sudo iwconfig wlan0 power off
But every time I connect to a network, power management turns back on. I've searched for solutions, but I've only found ways to make sure power management stays off when you login, reboot, etc. I think I might be able to sort this out with systemd hooks, but I don't know how that all works.
Here's what I've got:
- Ubuntu 15.04
- Lenovo thinkpad yoga
- Intel Wireless 7260
- kernel version
This is not a duplicate of Why doesn't Ubuntu automatically disable wireless networking when a wired connection is active? , but information from that post was relevant to this.
