I am new to linux and know very little about networking to begin with. Im trying to get a basic understanding of the interfaces and why there are so many. I am using the network tools program and the output for network services using netstat is:
Network device: lo
Hardware address: Loopback
Multicast: Disabled
MTU: 65536
Link speed: not available
State: Active
Transmitted packets: 7380
Transmission errors: 0
Received packets: 7380
Reception errors: 0
Collisions: 0
and
Network device: wlp2s0
Hardware address: 74:70:fd:e4:6c:68
Multicast: Enabled
MTU: 1500
Link speed: 130 Mbps
State: Active
Transmitted packets: 362471
Transmission errors: 0
Received packets: 1039420
Reception errors: 0
Collisions: 0
Do I need two interfaces?
What are all the different ip addresses?

Do I need two interfaces? What are all the different ip addresses?
First things first; you don't have any more interfaces in Linux than you do in Windows or Mac. The 'lo' device is the loopback, and every machine everywhere has it, along with the same address: 127.0.0.1. That is also known as 'localhost' (typically). The wlp2s0 interface is your wifi adapter, in this case.
And to go through what you're seeing with netstat, it's just showing that you have TCP/UDP enabled (normal), and that it's listening for connections. You can see the same sorts of information on Windows, too...although it's much harder to see. If you plug in a wired connection, you'll see another interface come up along the lines of 'en0' or 'eth1'. But networking is a broad topic; I'd suggest putting "linux networking basics" into Google, and reading some of the results, to get you familiar with some things first. https://itsfoss.com/basic-linux-networking-commands/ https://www.networkworld.com/article...-beginner.html
The speed is what’s strange. Works great until I download something. My download speed ranges from 12 kB/s to max of 50 kB/s. I always appear to a have a strong Wifi connection so I thought maybe there is some setting that needs to be changed?
I know I’m extremely ignorant about networking in general so don’t feel compelled to explain ur answers. Any thoughts are greatly appreciated. Helps to direct what I shud be googling.

Read the LQ Rules about text-speak, and about not using it.
And there could be many reasons for slow connectivity. But you don't say anything about your computer hardware, network hardware, router, or even version/distro of Linux. We can't even begin to suggest a starting point, since you provide no details. Start with version/distro of Linux, brand/model of computer, and we can try to go from there.
