I am new to Ubuntu and I am getting to learn how to use it. I have learned quite a bit trying to figure out this problem myself by reading forum posts, asking my Linux savvy friends, and skimming some books.
I have a SSD and HDD setup, and when I first installed Ubuntu, I had a swap partition as part of my SDD hard drive. I shortly afterwards found out that was a bad idea because it would shorten the lifespan of my SSD. However, my wireless card was working at that time. So, I know that drivers exist and it works in 16.04. After I re-installed Ubuntu 16.04 with a swap partition located in my HDD, my wireless card no longer works. It says the "Device is Not Ready". I have gone into the System Settings>Network and made sure the card is turned on.
Other steps I have taken include lspci | grep -i network
returns that I have a Ralink corp. RT3290 Wireless 802.11 1T/1R PCIe card. I then did ifconfig
and it returns "enp4s0 . . . . link encap:Ethernet..." "lo . . . . link encap:Local Loopback..." and related computer attributes.
After doing more research I found some more commands and decided to try them out. iwconfig
returns lo no wireless extension. "enp4s0 no wireless extensions" "wlp3s0f0 IEEE 802.11bgn" "ESSID:off/any Mode:Managed" "Access Point: Not-Associated" "tx-Power=0 dBM" ....
Again, more research leads me to sudo apt-get update && sudo apt-get install build-essential linux-headers-generic
and after a few short computer tasks it returns "0 upgraded, 0 newly installed, 0 to remove and 11 not upgraded"
Lastly I found a post that had information pertaining to a wireless info script found here
My wireless/WiFi connection does not work. What information is needed to diagnose the issue?

I hope this is enough information to help me fix this issue. Thank you.

'dkms status' returns

This seems to refer to my graphics card's proprietary driver. When I've checked additional drivers in the system settings, there is no other option regarding my wifi card.
I have disabled secure boot from my computer's bios settings. I also turned off quick boot. However, my Ubuntu is recognized as UEFI bootloader (I might have this lingo wrong, but I made sure to install grep that I can use without enabling legacy mode). Ubuntu is recognized as a startup item in the main list.

exists in 16.04 by default. No separate installation is required. BTW, my suspicion is secure boot.
