Ralink RT5390 not being seen in hardware

[D-pc-user]

System is setup to switch between Windows 7,  Windows 10,  and Ubuntu.  All OSs are up to date.  About a year ago I entered commands under UBUNTU to turn off the Ralink RT5390 so it wouldn't try to connect when network cabled.  The RT5390 was turned off and did not appear on any of the OSs.  I want to move the computer to a location where I will need the wireless connection.  I cannot find the instructions that I found on the Internet to turn off RT5390 and restart it.  The RT5390 does not show up in any of the OS hardware configurations when I look at "Control Panel - System - Device Manager - Network Adapters" .   I have removed the RT5390 from the Motherboard and rebooted the system, then reinstalled it and rebooted the system to see if the BIOS and system would recognize it, but still not seen by any of the OSs.  Does anyone know how to turn the RA5390 back on?

Thank you

Lil_Boy_Blue,

Thanks for your suggestions.  W10 only shows the Realtek PCIe controller, not the Ralink WIFI board.

Hi

Well while it may be an issue with the BIOS or even a failed adapter card, there is something else you could try...

When troubleshooting wireless, it's important that your system is fully updated by opening a terminal, CTRL+ALT+T. Using a wired internet connection, please run:
Code:

sudo apt update
sudo apt dist-upgrade

and reboot if necessary.

If the issues persist, it is recommended that you install pastebinit, by running:
Code:

sudo apt install pastebinit

This will enable the wireless script to, upon your approval, upload the obtained data to pastebin, creating at the same time a link to it in your terminal, permitting you to paste it to a forum thread.

Once that's done, download and run the wireless info script, which will gather information to help diagnose your system. You can run it using this command:
Code:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

It will create the file "wireless-info.txt" at the location it is run from, and depending on its size, an additional archive called "wireless-info.tar.gz". If you prefer, you can post the file directly to pastebin yourself. Sensitive information like MAC addresses and WPA/WEP keys are masked automatically.

If you aren't able to connect to the internet with the affected system, including via a wired connection, just navigate to
https://ubuntuforums.org/showthread.php?t=2082305&p=12350385&viewfull=1#post12350385 using another device and follow the instructions there on how to the run wireless script without an internet connection.
