I just upgraded from 14.40 to 16.04 on an HP 250 G3. Everything worked fine until i hit the f12 button which is for switching wifi on and off on this machine. It doesn't turn on anymore. What could be the problem?

I trid rfkill unblock all as in this thread https://ubuntuforums.org/showthread.php?t=1768398 but now it's written device not ready under the wifi icon.

rfkill list all:

0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no

lsmod | grep -e wmi -e lap:

hp_wmi                 16384  0

wmi                    20480  1 hp_wmi

The result of dmesg | grep rt2 can be found here

The result of rfkill list all is 

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

i tried to install drivers as here in second answer step 1 to 8 but i got

I have seen this error before:

rt2800_wait_wpdma_ready: Error - WPDMA TX/RX busy

Please see: https://forums.opensuse.org/showthread.php/506888-OpenSUSE-13-1-wireless-problem-with-firmware-Ralink-RT3290-(kernel-4-0-0-1-1-g49e42b3-x86_64)

In the post I linked, it says:

While I was waiting for answers I did recall reading someone in these forums suggesting to remove 802.11n from the router .

So I tested that today it it worked.

That is, I set the router to broadcast only 802.11g. ( Previously 802.11n was among the protocols it broadcasted.)

And it WORKED. wlan has been on since this morning with no glitch.

Also see: https://ubuntuforums.org/showthread.php?t=2334099

YES!! I removed 802.11n, leaving both "b" and "g" on, and it works!! thank you very much!!

Please change the setting on your router to use 802.11B and G only and not N. Reboot the router and see if you connect.
