Very slow internet connection


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:

Protocol IP Source Port/Service State
tcp 127.0.0.53 53 LISTEN
udp 127.0.0.53 53
udp 0.0.0.0 68
udp 0.0.0.0 5353
udp 0.0.0.0 45429
udp6 :: 32971
udp6 :: 5353
raw6 :: 58 7

I have two interfaces:

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?

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.

Well, wireless speed depends on your Modem as well and your position relative to it.

Your info seem to indicate your wireless card is up with a possible speed of 130 mbps which is "very fast".

Hello and welcome to LQ.

I am a bit confused. The slow internet issue, is it that you have paid for some very high speed home internet and your new linux system seems slow?

Define slow, browsing very slow? Download is slow?

How about your other system like your phone, or other devices is it the same?

Check out link below, you might get some ideas:

The speed is whatís 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 Iím extremely ignorant about networking in general so donít 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.
