If you use a wireless connection on your computer, or wi-fi for short, you might want to monitor your wi-fi. This is a simple task in the terminal and won’t take too long to learn. So, if you’ve ever wanted to monitor your wi-fi, this is the article for you!

There’s more to your wireless connection than just the throughput. There are things like link quality and signal strength that might interest you. It doesn’t stop there, there are all sorts of other bits of information you can learn if you decide to monitor your wi-fi in Linux.

I’ve written a few similar articles, each using a different technology. If you’re interested in those articles, click one of the following links:

Those are all about monitoring bandwidth and your network connection speed. They’re all fit for purpose, but this article covers wavemon, which is quite different and more specifically about monitoring your wi-fi connection as a whole. This isn’t very complicated or anything. You’ve got this!

This will be done in the terminal, so you might as well prepare yourself for that. So many of my articles do indeed require an open terminal.

wavemon:

The tool we’ll be using is known as wavemon. Like most of these articles, it’s another tool that’s fit for purpose. We want to monitor the waves, radio waves that is. This is one of the tools for the job. In fact, you’ll find the man page describes wavemon like so:

wavemon – a wireless network monitor

To install wavemon, we’ll need an open terminal. You can frequently just press CTRL + ALT + T to open your default terminal emulator. Give that a go. If it doesn’t work you can find the shortcut in your application menu.

With your terminal now open, we need to install wavemon.

Debian/Ubuntu/etc:

sudo apt install wavemon

1	sudo apt install wavemon

RHEL/CentOS:

sudo yum install epel-release && sudo yum install wavemon

1	sudo yum install epel-release && sudo yum install wavemon

Arch/Manjaro/etc:

sudo pacman -S wavemon

1	sudo pacman -S wavemon

Fedora:

sudo dnf install wavemon

1	sudo dnf install wavemon

I think I have all of those correct. If not, please leave a comment down below so that I can fix it. If you’d like to add the code to install wavemon on other distros, please leave a comment below. I’m pretty good at getting back to commentators and tend to be quick at fixing articles.

Anyhow, wavemon is the tool you’ll want to use to monitor your wi-fi!

Monitor Your Wi-Fi In Linux:

Leave your terminal open from the installation phase.

This section of the article will be nice and quick. You don’t need to do anything else besides run the command. You don’t even need elevated permissions (such as sudo) for this.

With your terminal open, just enter the following command:

wavemon

wavemon

You’ll get a handy output (it may help to resize your terminal for this one) that’s full of information. An example of that output would be this:

I can’t get F1 to do anything, but F2shows a histograph.

If you do start wavemon with sudo, you can scan for wireless networks with the F3 button.

You can change some settings with F7 if you want.

The F10 button should quit the program.

If that doesn’t work, CTRL + C will exit wavemon.

But, you can see how much data you’ve received (during this session) and how much data you’ve sent (during this session). It’s all pretty basic stuff and wavemon is a nice and easy way to monitor your wi-fi in Linux.

Closure:

Well, that’s one way to monitor your wi-fi in Linux. If you use a wireless connection and want more information about that connection, wavemon is an acceptable tool for the job. There are certainly other tools out there and this is just one of them. It’s an easy tool to use and I find it’s familiar enough for anyone to understand with relative ease.

I did say that this would be a fairly easy article. It is indeed a fairly easy article! This is one of those things you can learn in just a few minutes. You never know when this information will come in handy. Then again, you might just be curious and want to know this information. You can customize it a bit but I didn’t need to do so.

Today is going to be a fun article, mostly good for lazy people, where we discuss a way to check if your network devices are connected. There are far easier ways to do this, assuming you’re local to the device. If you’re not local to the device, the fact that you’re connecting to it likely means that the network is at least somehow connected!

But, in the spirit of being lazy, let’s head into the world of sheer, unadulterated laziness. I mean, if you want to know if your wireless is connected there’s an icon. Of course, you can see if your ethernet is connected. To check that ethernet connection all you probably have to do is look at the back of the computer and maybe wiggle the cable a little bit.

This, of course, presumes that said network adapters are in working condition. If they’re broken, this tool might give you a bit of debugging information. But, still, this is a command that calls itself a “beat connector”. It’s mostly used to check to see if your network devices are connected – as in physically connected to your computer.

The tool we’ll be using will be ifplugstatus and it defines itself as this:

ifplugstatus – A link beat detection tool

At least as far as I use it and the man page indicates, it checks to see if your network devices are connected. Seeing as that’s what the title suggests, it means we’re probably off to a good start!

Check If Your Network Devices Are Connected:

First things first… You’ll almost certainly find that ifplugstatus is not installed by default. You’ll need to install ifplugstatus if you want to use it. To do that, you’ll need an open terminal – which you’ll need for the rest of the article. To open your terminal, press CTRL + ALT + T and your default terminal should open.

Now, I’ve only ever used this command with Lubuntu and similar. Because of this, I don’t know if it’s the same on other distros. (Feel free to leave a comment.) But, at least in Lubuntu, not only is ifplugstatus not installed by default, that’s not the name of the package you need to install. No, that’s a different name and to install ifplugstatus you will want to run the following command:

sudo apt install ifplugd

1	sudo apt install ifplugd

You’ll need to adjust that command to match the distro you’re using.

Anyhow, with ifplugstatus installed, you can check if your network devices are connected with just the following command:

ifplugstatus -a

1	ifplugstatus -a

But wait! There’s more! You can get a lot more information about your network devices by adding the -v (verbose) flag to the command. That flag automatically assumes the -a (all) flag, so it’s just:

ifplugstatus -v

1	ifplugstatus -v

There you have it… Instead of just looking in the status bar section to see if wireless is connected, or even looking around the back to see if the cable is connected, you can just check all that right there in the terminal – without having to move much more than your hands! You’re welcome!

Closure:

Heh… There you have it! You have another article. If you ever want to check for a beat, that is to check if your network devices are connected, you now know how to do so. You can even SSH into another device and check to see which of its network devices are connected (beyond the obvious one you’re connecting with). You don’t even have to leave your seat.
