Ubuntu – Ubuntu 16.10 Wifi Trouble – RT2561/RT61

16.10driversnetworkingpciralink

I've used Ubuntu before, but I'm still very new. I just installed 16.10 on a new computer yesterday, and the Wi-Fi has been considerably slower than my Windows laptop. I put the computer together mainly to play Dota 2, and I experience decent ping but constant 5%-10% packet loss while playing. Occasionally, after the computer has been left on for a while, the Wi-Fi connection will drop completely- I can still see networks in the drop down menu, including my home network, but my computer will not reconnect without a reboot. I've looked all over for a solution, but my inexperience has prevented me from getting anything to work. My Wi-Fi card is a Ralink RT2561/RT61, here's some info

The output of sudo lshw -C network

 *-network

Here is the output of sudo iwconfig:

I'm at a loss, I'm very bad at this. If any additional info is needed I can provide it

  • I have a RT2561/RT61 and I finally solved this problem by:

    Edit this file as root:

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

    Changing wifi.powersave = 3 to wifi.powersave = 2, which will disable powersave (as mentioned before, from github)

    And then restart the network manager as root:

    sudo systemctl restart NetworkManager

    You don't need to reboot. You can now connect to your wifi device
