APSync on RPi2 - no WiFi

I have flashed an sd card with APSync and RPi2 boots with no problem (I can access it via SSH and I can see the web page). However, I can’t see wi-fi access point nor blue light in the dongle (Edimax EW-7811Un).
I can setup clean raspbian and get wi-fi working (even in AP mode) on this Pi with this SD card and this dongle. I can’t do it with APSync for some reason though.
If I try to build APSync using github instructions, I experience some errors during installation and eventually wifi dongle stops working sometime during installation.
Please help!
