So, I've installed elementary Hera on an old netbook (intel N455) and the wifi didn't work but LAN works just fine. I've tryed this recomendation http://www.techytalk.info/ralink-rt3090-ubuntu-driver-ppa/, but the repository has problems and can't install it.
When I run rfkill this is what shows up:
0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes
As well I checked the bios setup and doesn't appear any lock. Neither there is a hardware button to lock it on or off (in win10 just works fine). Would be better to install an older distro?
