Now that we know what Wi-Fi hackers can do subsequently a router hack, let's look at what you tin can do to finish it.
How to protect Wi-Fi from hackers
Past taking only a few simple precautions with your Wi-Fi router, you lot tin can make it a lot more difficult to hack. As is the case with many things in life, preventing Wi-Fi hacking is cheaper and easier than dealing with a hacked router. Once that happens, your trouble will get considerably more than difficult, though not impossible, to solve.
Here's how to cake Wi-Fi hackers with smart router security:
Change your router's admin credentials
All routers have a username and password that's used to access your router'south settings. Whenever you get a router, whether information technology'south new or used, immediately change the username and password.
Wi-Fi hackers know the manufacturer's default admin credentials for about all the pop routers on the market. If someone can reach your Wi-Fi network, they can try logging into your router with that info. If you lot've never updated the login credentials afterward getting your router, you're setting yourself up as an easy marker for a router countersign hack. And if you bought a router from someone else, yous can't be sure who has that old login info. Either way, change it up ASAP.
Set a new router countersign using strong countersign creation practices — or create a truly uncrackable countersign with random strings of characters — to block Wi-Fi hackers from easily breaking into your router.

Enable WPA2 or WPA3 encryption and then that anyone who wants to connect to your protected router will need your Wi-Fi password. And be certain to set a potent password by following smart password creation habits. These unproblematic steps volition give any would-exist Wi-Fi hacker a serious claiming.
Change your router's network proper noun (SSID)
While you lot're configuring your router — changing your admin credentials and setting a strong password — change the SSID likewise. SSID stands for service set identifier, which, in everyday terms, is the proper name of your Wi-Fi network.
New routers frequently display the brand of the router in the SSID, and Wi-Fi hackers can use that data to help them crack your password. Set up a custom network name instead so that they won't know which type of router y'all have. The more than clues you give a hacker, the easier their job will be.
Go creative with your Wi-Fi network name: arrive long and circuitous. WPA encryption uses the SSID as part of the algorithm, so by avoiding default or common network names, you'll make your network more than resistant to password nifty methods like rainbow tables. Besides, it's fun to requite your neighbors something to chuckle nigh.
Disable WPS
Along with WPA2 or WPA3, many routers besides accept WPS (Wi-Fi protected setup) — pregnant you tin button a button or enter a Pivot to connect, as opposed to using the password. While it'southward clearly more convenient, the level of security plummets when using buttons or PINs instead of passwords.
Anyone who can physically bear on your router will exist able to push the WPS button and connect. And a short PIN is far easier to crack with a brute-forcefulness assail than a lengthy and complex countersign.
Unfortunately, not all routers support deactivating WPS features, but if yours does, turn WPS off ASAP and set a password.
Deactivate wireless/remote administration
Remote administration lets you log in to your router'south admin settings from anywhere in the world. Simply unless you're a programmer, chances are slim that you'll ever demand to do this. If you conciliate this feature, you lot'll only be able to access your settings when your reckoner is physically connected to your router with an Ethernet cable. Deactivating remote assistants is a convenient way to keep hackers out.
Update your router'southward firmware

Firmware updates can protect your router against any vulnerabilities that might be discovered in older versions of your firmware. Some routers will be able to check for firmware updates, only yous can e'er log in to your router's admin settings, discover the firmware department, and take a look for yourself.
