Hi everybody!
I have a Pi 3 with Ubuntu Mate.
It all worked well until recently. The Pi is headless (no monitor at the moment), so I mainly SSH to it via Ethernet.
I had my wifi disabled because of no use.
Now I'm trying to resurrect it, but the situation is weird. When I boot the Pi, and ping it's wifi address, it comes up for seconds:
Request timed out.

Request timed out. <----- its booting, 10-15 seconds since.

If I check "rfkill list", it says:
0: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
1: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

I manually unblock it, and wlan0 seems to come up, but 50/50 chance. Sometimes works, sometimes not.
Tried to put "rfkill unblock all" into /etc/rc.local - no luck.
Tried creating a service - no luck.
Any ideas what it might be? Thanks!
