ready a strong router password, a hacker can go inside your router in minutes. Once they’ve gained control, the hacker tin can change your router settings, access your internet data, or fifty-fifty install malware on your router. These are all signature signs that you’ve been striking by a black-lid hacker, as opposed to their more altruistic white-hat cousins.

How router hacking works

Depending on the router you have and how well you’ve secured it, aspiring Wi-Fi hackers can try one of several attack methods to breach your router security.


Using the default login credentials:

This is the easiest style to hack someone’s router. If yous’ve never changed your router’southward admin password, anyone can simply log in with that information. Router hackers know the standard passwords for the nigh popular routers, and they’ll happily try these out on your Wi-Fi network.


icon_02Exploiting a firmware vulnerability:

Firmware is the proper name for built-in software that tells a hardware device, such as your router, how it should work. Software vulnerabilities are security flaws that hackers tin exploit in their attacks. If your router’s firmware has a vulnerability, a router hacker can leverage it to access your router’s administrative settings. Regularly check your router manufacturer’south website for firmware updates, and install any that you find.


icon_03Nifty your password:

    Botnets are massive networks of hacked devices controlled by a cybercriminal. Hackers often use botnets in large-scale cyberattacks that overwhelm targets with information to shut them down.

    These distributed denial of service (DDoS) attacks require huge botnets to pull off, but the consequences tin be disastrous. Botnets are too used to send spam or scan the internet for other vulnerable routers. Some of the nearly famous hackers in the world target everyday computer users to create big-scale botnets.

2. Perform a manufacturing plant reset

With your router cut off from the internet,
hitting it with a factory reset.
This goes across the common off/on toggle yous’ll do when your internet cuts out. A manufactory reset removes all your configurations and returns your router settings to a like-new country. Some types of router malware, like VPNFilter, will besides exist removed later on a factory reset.

For specific instructions on how to reset your router, bank check your user transmission. Many routers have a modest recessed reset button that y’all’ll need to press with a paperclip.

three. Log in and change your admin countersign

4. Create a new SSID and password for your Wi-Fi network

The SSID (service ready identifier) is the name of your Wi-Fi network. Your router may include its brand proper name in the default SSID, which is a big help to a would-be router hacker. Knowing the type of router you take may arrive easier for someone to hack it.

Set a new SSID instead, and arrive
long and complex. WPA encryption, which your router uses to protect your password, includes the SSID in the encryption algorithm. Due to how this encryption works, shorter or more common network names tin can exist easier to crack with a rainbow table or other assistance.

Apply these rules to your password also
— long, complex, and unique is e’er best. Create a countersign that contains at to the lowest degree 15 to 20 characters. Y’all can’t go wrong with a longer password.

5. Create a guest network (if yous want)

Invitee networks are separate networks on your router that grant internet access to devices yous don’t want connecting to your master network. They’re groovy for when you have, well, guests coming over, as you never know who’s got a malware infection on their telephone.

Isolate unfamiliar devices on your invitee network
to prevent them from communicating directly with (and possibly infecting) your own stuff.

Guest networks are besides ideal for less-secure smart devices, which frequently have weaker protections than computers and phones. You’ll find your guest network options in your router settings.

vi. Update the firmware on your router

If your router doesn’t automatically update its firmware — and many don’t — yous’ll have to DIY. Caput to your router manufacturer’s website and look for their “downloads” section. Hither, you should observe a selection of router firmware.

Download and install the latest firmware for your router

— preferably from another manufacturer who isn’t going to expose you to hackers.

How to prevent router hacking

It takes but a few piece of cake changes to your digital lifestyle to avoid about router hacks. And it’due south way simpler to prevent router hacking than it is to deal with the consequences of getting hacked.

Observe out how to block Wi-Fi hackers with these helpful tips for greater router protection:

Create a new admin username and password for your router

As soon every bit you lot get a new router,
set a new admin countersign. Hackers know the default passwords for all the popular routers, and they could try them out on yours. If you’ve bought your router secondhand, keep its former users out past updating the countersign. And if you tin can, alter the admin username as well.

Follow strong countersign cosmos practices to prevent anyone from guessing your countersign. A long password of at least xv to 20 characters is very tough to crack.

Create a
brand-new password for your router, as well — don’t reuse one from another account. Some router vulnerabilities can leak your password, and you lot don’t want a hacker to get the keys to your financial, email, or social media accounts.

Disable remote access settings

Tin can yous retrieve of a reason why you’d need to log into your router’south admin settings when you lot aren’t physically next to it? If not, at that place’s no reason to leave this window open up to others.
Check that remote admission is deactivated
so that y’all can log into your router simply with a good, former-fashioned Ethernet cable or via your Wi-Fi network.

Opt for WPA3 support

WPA3 is the latest iteration of the
Wi-Fi Protected Access security protocol, which secures your Wi-Fi network with AES encryption — incidentally, that’due south the aforementioned loftier-level encryption we use for our AVG Secure VPN. Older routers won’t have WPA3, but they’ll likely take WPA2. It’southward the previous version, but it’due south still proficient.

And remember, again,
e’er create a strong and unique countersign
when configuring your WPA3 or WPA2 settings.

Ditch WPS

WPA3 and its predecessor WPA2 are reliably secure — depending on your password, of course — merely nosotros can’t say the same for WPS (Wi-Fi Protected Setup). By letting y’all connect a device by pressing a push button or entering a PIN, WPS is certainly user-friendly, only it’s far from secure.

Information technology’ll have a hacker way less time to fauna-force a short PIN than to crack your strong and unique password. And if you take a WPS button, that ways anyone who’due south near your router can connect to information technology in seconds.

If your router allows for it,
turn off WPS entirely
and protect your router with a WPA3 or WPA2 password instead.

Change your router’s network proper name (SSID)

Leaving the default SSID (the name of your Wi-Fi network) in place is a boon for a would-exist router hacker, as it lets them know which type of router you have. Instead, as soon as you’ve finished changing your router’s login credentials,
set a new SSID
as well. Longer and more than circuitous names are better, because they also enhance your WPA security.

And of grade,
create a long and unique network countersign. Shoot for a password that’s at least 15 to twenty characters long. The longer your password is, the harder it is to crack.

Update your router (and its firmware)

If you’re using an older router that doesn’t support WPA2 at a minimum, you should upgrade. Older equipment is more vulnerable to hacking, and
you’ll exist safer with a more current router model. If you lot buy a secondhand router, change your admin countersign, SSID, and network password ASAP.

The same goes for your router’s firmware. Periodically check your router manufacturer’s website to see whether a firmware update is available. If so, update information technology. This can forbid hackers from exploiting vulnerabilities in older firmware versions. Updating your router is also a nifty style to boost a weak Wi-Fi signal at dwelling.

Ready up a router firewall

A firewall is an internet blockade that isolates your network from unwanted traffic. With a unproblematic router firewall, only connections requested by your devices are immune to laissez passer through your router.
Many routers already come with a built-in firewall, so all you lot need to practise is enable information technology within your router’due south admin settings.
