Pinebook pro poor performance on 5Ghz WiFi

[Iolaum]

Hello,

I have been testing and enjoying my new Pinebook Pro. I 've noticed however that 5Ghz Wifi is performing poor. I have activated both 2.4 Ghz and 5Ghz wifi on my home router. Things I 've noticed:

• There are times when 5Ghz wifi is not working at all - as if there's no wifi signal available. Devices next to the pinebook, such as a smartphone, work fine with 5Ghz wifi so I know the signal is good but PBP can't interface with it.
  
• I 've tested wifi speeds when both 2.4Ghz and 5Ghz are working in the Pinebook. The 2.4Ghz connection easily gets 4+Mbytes/sec while the 5Ghz oscillates between 500Kbytes/sec to 1.2Mbytes/sec.
  The network connection is 150Mbps.
  

Has anyone else experienced anything similar?
