This is the download link for Orangepi PC Ubuntu mate linux os with Working wifi using MT7601 ralink wifi card.
Thanks to user http://www.orangepi.org/orangepibbsen/?162305 who compiled the driver. I am just providing you the complete SD card image for your orangepi pc.
This is updated image.
This image is configured to work with  hdmi-dvi monitor, headless via tight vnc server, usb to serial.
Note: never run

Steps:

• Download the image,unzip via 7z(windows) and write to sd card.
• connect ethernet and wifi card, then start.
• login to ssh via ethernet
• run code to enable wifi

  code:

  1. suno nmcli -a d wifi connect
  
  

• add you ssid & password.

• reboot to take effect

• remove ethernet

• check router dhcp to check weather it is connected with wifi

• again login via ssh.

• run the command to start vnc sever

  code:

  1. vncserver :1 -geometry 1920x1080 -depth 24
  
  

• using vnc server uses cpu making system slow.

• to access use VNC viewer or Remote Desktop Client

  
  

If you have hdmi-dvi monitor, just connect it and boot.

Nearly everything works; after second boot  hdmi-monitor green!

This image is only for Hdmi-Dvi monitor,
If you connect hdmi monitor it will turn green.
Sorry, the software are still buggy.
I you want to use hdmi monitor you have to use original script.bin file provided by loboris
