Hello professor and classmates. On my home network I use WPA3. Its the newest security standard, and honestly, it makes life easier because I dont have to worry as much about someone sneaking onto my network. The big win with WPA3 is that it encrypts everything better than the older stuff, so your data, like passwords, photos, and whatever youre streaming, is way safer. Plus, it helps protect even if someone tries to guess your password. The downside? Some older devices dont support it, so occasionally you have to fall back on WPA2, which isnt as strong but still decent.

To really harden my network, I do a couple of things. First, I change the default router username and password. Youd be shocked how many people never do this, defaults are basically an open door for hackers. Then I turn on MAC address filtering, so only devices I approve can connect. Its not perfect, but its an extra barrier. I also hide my network name by disabling SSID broadcasting, so it doesnt show up in the usual Wi-Fi list, makes it less tempting for random people to try to connect.

All together, its like putting a strong lock on your door, adding a deadbolt, and then putting up a private property sign. It doesnt make it impossible for someone determined, but it definitely makes it harder for casual intruders. Your Wi-Fi and devices feel a lot safer that way. Some routers let you limit the number of devices connected at one time. This isnt perfect, but it helps you notice if an unknown device connects.

Hello class,

At home I use WPA2/WPA3 mixed mode on my Wi-Fi. Id rather use WPA3 only, because it is the newer and stronger option, but real life is different than the textbook. In my house there are phones, TVs, game systems, and random smart devices, and not all of them always work right with WPA3 only. So mixed mode is kind of the middle ground. WPA3 is better for security, but WPA2 is still around because a lot of older stuff still needs it. The good part is it gives me stronger protection while still letting everything connect. The bad part is if older devices are still using WPA2, then the network is not as locked down as it could be. The FTC says WPA3 is the newer and better option, but WPA2 is still acceptable for home use if that is what your gear supports.

For me, home network security is not just about setting a password and forgetting it. Im a retired Marine, and I look at it like home security in general: the front door matters, but so do the windows and side doors. One way I harden my network is changing the default router admin login and making sure the Wi-Fi password is strong and different. That matters because if somebody gets into the router settings, they can mess with the whole network, not just the Wi-Fi password. Another thing is keeping the router firmware updated. That part is easy to ignore, but it matters because updates fix known security problems. FTC and CISA both recommend changing default settings and keeping router software up to date.

Another two good ways to harden a home wireless network are turning off WPS and using a guest network. WPS is convenient, but it can weaken security. A guest network helps because it keeps visitors or smart home stuff away from your main devices like your laptop, phone, or anything with personal info on it. That makes sense to me because a lot of weak points in a home network are not the main computer anymore, it is the extra devices people forget about. The FTC also recommends turning off features like WPS and setting up a guest network for better separation.

Overall, I think the best answer is layered security. Use WPA3 if your stuff can handle it. If not, WPA2/WPA3 mixed mode is still solid. Then back it up with stronger passwords, firmware updates, WPS turned off, and a guest network.
