This guide will help a person with intermediate computer knowledge quell a suspicion of an intruder on their network. If you suspect there is an outside user on your network then use this guide now to make sure you can detect them before they do any damage or make your (ISP) internet service provider overcharge you on your download usage bill.

Firstly you will need to open the command prompt to find your default gateway IP address as it will be different on most computers. To do this just hit Win+R (Windows key + R) and then in the dialogue box that pops up type “cmd”  and click “OK” or hit “Enter”.

Once your command prompt has opened you will need to type “ipconfig”. This command will show you everything about your computer’s current network settings and will highlight your default gateway, which of course is what we are trying to find.

Now you will need to open your web browser and type your default gateway address into the URL bar (bar at the top of the screen where the website’s address will appear). Once you have typed it in click “GO” or just hit “Enter”.

You will now be prompted to enter a username and password (This is to access your modem and its configurations). Enter your username and password, which; unless it has been changed after purchase will be:

username: “admin”

password: “admin”

If you entered your username and password as written above you should have access to your modem – if not, then it is recommended that you check the bottom of the modem for any possible usernames or passwords. If that fails then contact your ISP for more information on the default username and passwords settings of your particular brand of modem.

Once you find out exactly what your modem’s login details are (username and password) then you will be able to decide whether or not it is difficult enough to keep unauthorized people from thieving your internet. To change your password look for a tab relevant to “Administration” or something very similar. You will be able to enter your old password and then your new password then you will be able to save it,making the new password permanent (until you change it again). Be sure to record the password on paper and store it somewhere safe. Also, while you are in the administration  section of the modem, now is a very good time to make the modem create a log of IP addresses that are using it. This can be done by searching through your modem’s tabs and finding something similar to “IP logging” and enabling it. I say “something similar” not because of a lack of understanding of modems but rather a lack of knowing the exact type of modem that you are currently using.

Now you will be able to secure your home or workplace modem to prevent would-be hackers gaining entry to your modem and using your valuable data bandwidth and quota. Thus preventing the risk of you unknowingly running over your internet limit. Enjoy your newfound network security knowledge.
