Installed PCI Board for Wireless Connection.
 

Normally I use a wired connection due to better signal strength, but while visiting a friend for several weeks I encountered the following: (1) My friend did not have a wired connection in the room we were living in. (2) Slow internet, Wi-Fi, service. (3) A brick wall (among two walls), and a long distance, from the router caused a weak signal.

So,instead of a dongle, I decided to install a wireless PCI in the computer to obtain the maximum Wi-Fi signal strength. This was my first attempt in installing a PCI adapter in my computer so I was hesitant.

After an internet search for a PCI board that would be compatible with my Linux 19.1 OS, I decided to install a, "TP-link, 300 Mbps, wireless N, PCI Express Adapter, TL-WN991ND." I did notice that on the PCI adapter box it had this notice, "Linux Support."

After the physical installation, the TP-link PCI Express Adapter worked perfectly with my Linux 19.1 OS.

Here is the ~$lshw -businfo:

Hopefully this success in obtaining a good wireless signal in a challenging Wi-Fi environment will help others considering installing a PCI board.

If there is any other coding information, or other information, needed for your information please let me know.

I've got almost exactly the same wifi PCIe card in my machine. That said, it would probably be better if you ran the following command to give better info;

which should give you something like;

It's what's in bold that's the info I'm talking about - so you could just omit what's above that for whatever ethernet interface your machine has.

Thank you. Here is my coding information:
