Configuring a Router
Nowadays, a wireless router is required for nearly every home. I personally do not know anyone that does
not have one in their house. A lot of you purchase routers with a lot of great features
but may not know how to use them. Even if you do not consider yourself an
expert with computers, you can learn how to use them yourself. I will walk you through how to change some
basic settings that will benefit you and anyone that is connected. I will also
do my best to explain some of these settings and features so that you are aware
of how the changes you make will affect you and your home network.
How do I access my router?
There is a label either on the bottom, side, or back of your
router. It should have things like hostname, IP
address, username, password, pre-shared key, and more. Find the label and take note of either the hostname or IP address,
whichever is available. For example, in the picture above, we can see the
IP address: 192.168.0.1. This is also a good time to write down the username
and password. You will need this later to log in to the router.
If you cannot find either one of these or are unsure, do not
worry. I will show you another method for finding this.
We can easily use command prompt or Windows Powershell on
your PC to find the IP address of your router. You can open command prompt by
clicking the start button, then scrolling down your list of programs until you
find Windows System. If you right-click on the start button, you can
click Windows Powershell (See pictures below). You can search for either of
these in the Windows search bar at the bottom of your screen.
Windows Powershell/Command Prompt
Once you have either of those open, just type in this command: ipconfig (see picture below). Once you enter 'ipconfig' with no spaces, hit Enter. Then your networking information will appear in command prompt or Windows Powershell.
**Just know if you are using command prompt then your screen should look identical to this. The only difference should be the username that I covered up.**
What we are looking for is the Default Gateway IP
address. The default gateway, in this case, would be your router. You will type
the IP address listed next to Default Gateway into any web browser (Chrome,
Edge, Firefox, etc). You can see we used Command Prompt in the picture below.
If you are using Windows Powershell, it will look the same but the windows will
just have different colors.
**It is very likely that your IP address and default gateway will start with 192.168.xx.xx**
Signing into your Router
Once you have typed in the IP address of your router in your
web browser (see picture above), you should see a screen similar to the picture below. From here
you will need that username and password listed on your router. The password is
typically something basic like ‘admin’, ‘1234’, or ‘password’. Remember this
step because we will be changing the password later.
Once you have signed in, congratulations! You have
successfully accessed your router. Take a moment to get familiar with the user interface and layout of your
router settings. Be sure you don’t click save or apply on any pages so you don’t
accidentally change anything.
If you try that username and password and it is not working or you have simply forgotten what it could be then you
can reset the router back to original settings. You can find more information on how to do that here.
Navigating through your Router
Once you have signed into your router, you should see a
screen similar to the one below. The first settings you should change are the
password to both your router (the one you used to sign into it) and the
password to your Wi-Fi (this is the password you would type in on all of your
devices to connect them).
**Changing the Wi-Fi name or password WILL disconnect any
device that you currently have connected. You will have to connect all of them
again using the new password or to the new Wi-Fi name**
Now, to change the name of your Wi-Fi and the password, you
will want to find Wi-Fi settings or Wireless Settings. Different manufacturers
will have different labels for this so just look for those keywords. You can
see the Asus router shows ‘Wireless’ under Advanced settings and the Netgear
router lists it as ‘Wireless Settings’ under Setup. It can even be found under
Security or Wireless Security.
Changing the Wi-Fi password
Once you have found the correct screen, you can change your password
to whatever you would like. It is very important that you have a secure password for your Wi-Fi. Typically, a longer password = more secure. Adding symbols and numbers can also make it more secure. Be sure that WPA2
is selected as the security method. If you also have the option for
‘Encryption’ select AES. Once you have typed in your new password and selected
these settings, click in ‘Apply’ or ‘Save’.
If you are currently accessing your router through Wi-Fi, it
WILL kick you off after you change the password. You will just have to sign into Wi-Fi once the router restarts. After connecting to the router, you
can type in the IP address of the router again and log back in.
One thing I have to mention is that many routers have 2
different Wi-Fi names that you can connect to. You may have noticed that your
Wi-Fi names have ‘2.4G’ and ‘5G’ in the name. This is because your router can
emit a Wi-Fi signal using different frequencies, these routers are called "dual-band". The 5 GHz band is faster and is
better for most modern devices. However, the signal does not reach as far as
the 2.4 GHz band. If you do not have a strong signal on the 5 GHz Wi-Fi then
just connect to the 2.4 GHz. The reason I want to mention this is because you
can set different Wi-Fi names and passwords for each of these. If you look in
the pictures below, you will see the D-Link router has two different boxes to see
the name, password, and security for each frequency. Make sure that you change
the password to BOTH. You can use the same password or a different one for each
Changing the Router Password
The last thing we will do is change the password to your
router. It is potentially the most important step in securing your home
network. Just be sure you set a secure password for this but do not forget it!
If you happen to forget this password, you will have to reset the router and
reconfigure everything that you have already done.
Now, this setting can be under different setting screens
depending on your router. It could be found under Administration, Maintenance, Management,
or Advanced settings. If you look at the pictures below, you can see that the
setting is found under Administration then Management on a Linksys router. For
the D-Link router it can be found under Maintenance then Admin. Also, you can
see on the Linksys router, you have the option to change your username too.
This is recommended if you have the option. Just remember after you type in
your username and password to click on save or apply. Once the router restarts,
you will have to log back into the router with the new username and password.
Now, you have successfully just made your home network more
secure. Give yourself a pat on the back! Just remember to only give your Wi-Fi
password out to people you trust and NEVER give anyone the password to your
router. You can always change these passwords as often that you feel is
necessary. Anytime you suspect someone is using your Wi-Fi without your
permission, changing the password can solve that problem. They would be
disconnected (along with all of YOUR devices) and would not be able to use your
Wi-Fi again unless they got the new password.
I hope this helps a lot of you out there. Please comment
below if you have any other questions! Thank you for reading.

You skip right into what shows on the command prompt, but you don't explain how you got the ip address info to show up. Maybe include those steps for users that are unfamiliar with this process entirely and don't know how to use commands? Just a suggestion, otherwise a very helpful tutorial. Good Job!
Hello! I recently moved to LA with some college friends and the house we are in is a bit whimsical meaning that it was originally two separate houses, each with their own separate circuit breakers and systems. The owner decided to combine the houses into one without putting the whole house on the same breaker. The problem we face is we can only find ethernet access on one of the systems and not the other. We are all interested in hardline adapters for our pcs because we game and do video editing on a regular basis. Is there a way to set up a hardline or a workaround for this problem? any info would be greatly appreciated!
