Ralink RT5390 wifi not working

[bullfluga]

Got a Asus with Intel i3 laptop and removed Windows 8. Installed Kubuntu 14.04 and wifi does not work.
I have a Ralink RT5390 wifi 802.11n 1T/1R PCIe.
Thanks.

Welcome aboard, bullfluga!

When you were installing Kubuntu, did it recognize the wifi networks around you, and give you the chance to connect to one?

[bullfluga]

No. Kubuntu saw the Ralink but when I clicked to select it, it would not allow me to enter a password or continue the installation further unless I deselected it.

        Kernel driver in use: rt2800pci

works fine @hear
do a

lspci -k

and see if the same kernel driver is in use.
if yes ,,,,,,,,,,,look to the keybord or on the case some where for a on/off switch ,,,,,,,,,@hear it is the F12 key (it has a symbol of an antenna on it and a LED that is orange when off and blue when on) but you may have a switch on the case .

if you do a

iwlist scan

do you see AP's ?

I tried to turn on the wifi by pushing Fn + F2 (has wifi symbol) on the keyboard and nothing happened.

[GreyGeek]

Show the output of lspci and lsmod.

[bullfluga]

Now it works!! I tried repeatedly hitting Fn+F2 and suddenly my wifi woke up from its deep slumber!
Thank you for all your patience and help!



Update: wifi working fine!

Works great now!

[DoYouKubuntu]

Fantastic!!

On one of my previous laptops, its wifi switch was on its FRONT EDGE--and it was continually getting accidentally moved. I remember one time--before I realized what had happened--being like, WTF?!! why did I just lose my connection?!!
