4 QUICK CYBERSECURITY STEPS EVERYONE MUST TAKE RIGHT NOW

1. Your old router is easier to hack

Your router may be doing a fine job keeping you connected to the internet, but is it keeping you safe? The latest security standard is WPA-3, released back in 2018. Any router that uses WPA-2 encryption needs to be replaced.

Run an encryption check on your router. Go to your router’s admin menu. Under the Wireless or Security menu, you’ll see the encryption status. Need help? Tap or click for the steps to do this on my site.

If your router is not WPA3 compatible, WPA2-PSK AES is the next most secure option. It’s also a sign you need to get a new router. I’ll tell you how to select the best router below.

2. You’re missing out

When buying a router, you might as well future-proof your network. More and more devices support Wi-Fi 6, but that doesn’t mean a thing if your router doesn’t.

Wi-Fi 6 significantly improves two critical categories: speed and range.

Homes with a lot of connected technology — phones, computers, smart TVs, printers, smart speakers, and smart home devices — put a definite strain on a network. Wi-Fi 6 routers can easily handle 50 devices or more.

There’s something even better than Wi-Fi 6, though not many devices can utilize it yet. Wi-Fi 6 uses the 2.4 GHz and 5 GHz bands, while Wi-Fi 6e operates on the 6 GHz band. You’ll find this tech built into many mesh networks.

3. Your signal is weak in certain spots

Your home should have a consistent, speedy network. A single router works fine for small spaces, but what about multiple rooms and floors?

Mesh networks are more popular and affordable than ever. Rather than relying on one router, a mesh network adds satellite modules around your home, blanketing the entire area with coverage.

These systems usually come in sets of two or more units that work together. As far as your gadgets are concerned, the Wi-Fi mesh is one big continuous network that eliminates poor coverage, dead spots, and buffering.

4. Your devices need more juice

How old is your router? Routers that only support 2.4 GHz frequencies are dinosaurs.

Single-band routers only utilize the 2.4 GHz band and one wireless signal.

Dual-band routers use 2.4 and 5 GHz bands to transmit two simultaneous wireless signals, providing better performance.

Tri-band routers typically have 2.4 and 5 GHz bands and an additional 5 or 6 GHz band to transmit three total wireless signals.

Single-band routers need to be replaced. A dual-band router that supports 2.4 and 5 GHz will do the job for homes with less than five connected devices. Get a tri-band router that supports three signals for homes with more than five connected devices.

5. How to choose a new router

I always get requests from folks looking for help choosing a router. It's tough if you have no idea what to look for. There are pages for sale on Amazon with prices ranging from $20 to over $1,000.
