I'm trying to connect my machine to a 5GHz WiFi but I can't seem to do this on Ubuntu. I have a dual boot system on my machine, with OSX as the other OS, and on that, I'm able to connect and use on 5GHz. 

$ iwconfig
lo        no wireless extensions.

wlp3s0    IEEE 802.11abgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=1496 dBm   
          Retry short limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

enxc6d291c8c5d3  no wireless extensions.

I'm currently tethering on USB from my phone right now.

$ iwlist wlp3s0 freq

          Channel 136 : 5.68 GHz
          Channel 140 : 5.7 GHz

I'm certain my machine can run on 5GHz networks, but I can't detect the 5GHz network. Can someone please help?

  • I have exactly that problem (I'm dual boot with windows, any luck?)

The only difference that could cause this is a poorly implemented / misconfigured driver.

You havent included the make/model so I cant link you to any resources but chances are Ubuntu has pulled a generic and you'll need to manually install the most appropriate one instead.
