Good.
man-in-the-middle attack prevention . You should be. Man-in-the-Middle (MITM) attacks are, like, totally a thing, and your router is basically the gatekeeper to your entire digital life. If they get through your router, well, lets just say it aint gonna be pretty. But dont panic! Theres stuff you can do.
First, and I cant stress this enough, change the default password. Seriously. (Its like leaving your front door unlocked, basically.) Every router comes with a default username and password, and hackers know what they are. Go into your routers settings - usually by typing something like 192.168.1.1 into your web browser - and find the admin section.

Change that password, and make it a strong one! Think passphrases, not just "password123."

Use numbers, symbols, the whole shebang.
Next, keep your routers firmware updated. This is super important. Router manufacturers release updates to patch security holes (vulnerabilities, as the techy-types say). Ignoring those updates is like ignoring a leaky roof; its only going to get worse.

Check your routers settings for a firmware update option or even just go to the manufacturers site. Theyll have instructions there, hopefully.
Another thing, enable WPA3 (if your router supports it). WPA2 has been around for a while, and its got some weaknesses.

WPA3 is the newer, shiner, better security protocol. Not all devices support it yet, so you might have to do some research to make sure your stuff works with it, but its worth it for the extra security layer. (Think of it as adding an extra deadbolt to your door. Always a good idea!)
Disable remote management unless you absolutely need it. Remote management lets you access your routers settings from anywhere in the world. Sounds cool, right? But it also means a hacker can access your router from anywhere in the world.

If you dont need it, turn it off. Its usually in the routers settings under something like "remote access" or "administration."
Also, consider using a VPN. A VPN creates an encrypted tunnel between your device and the internet, making it much harder for someone to intercept your traffic. (Its like putting your mail in a locked box.) You can install a VPN on your computer, phone, or even configure it on your router itself, depending on the routers capabilities.
Finally, be wary of public Wi-Fi. Public Wi-Fi networks are often unsecured, making them prime targets for MITM attacks. Avoid doing sensitive stuff, like online banking, on public Wi-Fi. If you need to use public Wi-Fi, use a VPN. (I know, I said that before, but its important, okay?)
Implementing these steps wont completely guarantee youre safe (nothing ever does!), but they will significantly reduce your risk of falling victim to a MITM attack. And thats a pretty good start, dont you think?
