Hello,
I have recently upgraded from ubuntu 14.04 to 16.04 LTS version and I have been facing problem while connecting to wifi networks in both the OSs.
I am able to see all the available wifi networks but not able to connect that. I tried all the options available in ubuntu forums but seems some are working temporarily and some are not working at all. So I decided to post my concern with forum.
Below are my hardware datails,
Laptop : HP pavilion DV6 series laptop
OS type installed : Unbuntu 16.04 is parallel operating system in my laptop along with windows 7.
Below are the hardware details gained by executing the command lspci -vvnn | grep -A 9 Network

As per the solution explained in thead (Problems whit unstable wireless (Ralink RT5390) ) i tried my self but it worked temporarily and again same problem as earlier
I executed the below commands for temporary wifi connection,
sudo modprobe -rv rt2800pci
sudo modprobe -v rt2800pci nohwcrypt=Y
