Hi there,

I have two WiFi networks with unique SSIDs (one 2.4 and another 5.0Ghz)

The 5.0Ghz network is not detected by HifiBerry OS, only the 2.4Ghz...

Is there a way to enable this on the Pi 3B+?

Thanks,

Mark

  Forgot to mention I have the WLAN region set to Australia and have tried changing this to different regions but am still unable to see the 5Ghz network.

  It will simply connect to the first network that it finds. If it can access the 2.4GHz network, it will stop here. There is no need to probe other frequencies as the network is already connected.

  If you want to change this, you would have to create your own freq_list:

  I have tried reinstalling HifiBerry OS after disabling my 2.4Ghz network. When i do this the pi still doesn't find the 5Ghz network. I've tried setting the freq_list for my region (AU) but not having any luck. There seems to be options to make AC wifi the default in the hostapd.conf file but it doesn't seem to make a difference.

  Wondering if this issue is specific to the pi3B+?

  Thanks for your help anyway

  hostapf.conf isn't used at all for this. 
  
  What does
  
  iwlist wlan0 freq

  list?

  Are you sure this is a 3B+, not a 3B? What's the output of 
  
  cat /etc/hifiberry.state

  Now I have to charge you for this ;-)
  BTW: What version is this? It looks like it still has the "analoginput" bug for the Digi+.

  Yes. You can run 
  
  cat /etc/hifiberry.version

  Ok, this is still an older version that detects an analog input on the Digi. It's not really a big problem, but you might think about updating.

  You can just upgrade directly from the UI, or from command line.
  
  No need to download a new release from the web site.

  Yes, on the 3B+ you can also use BT
