How We Ranked the 5 Best Secure Routers

The oldest and slowest of the bands on a router is the 2.4 GHz band, but it sticks around for a reason. Generally speaking, while this band features the slowest available speeds and has the lowest bandwidth, but also reaches out the furthest. It’s not the best band to connect to connect if you need high speeds, but if you just need to be connected for light browsing or anything that’s low bandwidth, it works. Alternatively, if you own a lot of old devices, this band may be the only band they can “see” and therefore, use.

Given the age of the band, top speeds on 2.4 GHz cap out very quickly. We recommend a speed of at least 50 Mbits/s, but if you aren’t really going to be using this band for anything other than checking web pages, you can go lower. It’s worth noting, though, that this might lead to a more frustrating and laggier time on modern sites with lots of scripting and high-quality images.

The much faster 5 GHz band offers up much greater bandwidth and is much, much better at meeting high-speed demands. Streaming high-quality video, using streaming services, gaming, downloading large files and games – the 5 GHz band is what makes all of these activities quick and bearable. It reaches a lower range than the 2.4 GHz band, but it’s also much faster, so you’ll use it more, especially on newer devices that actually support the band.

Given how much you’ll be using this band, we recommend a speed of at least 200 Mbits/s to ensure you’re able to enjoy streaming and gaming on at least a few devices simultaneously. Any lower and you start to run into real bottleneck concerns, such as endless buffering, lagging, or drops in connection.

Router range is exactly what the name suggests: how far can you get from the router before you start experiencing issues with your connection? The complicating factor is the simple fact that range depends on the band you’re using. 2.4 GHz is a band that offers greater range, so it gives tests results that show a greater range than tests that use the 5 GHz band. In general, our research found most publications used the 5 GHz band, so our recommendations are based on that.

As such, we recommend your router have a range of at least 50 ft. This gives you a good “bubble” around the router that you can connect to, but it’s important to know that things like the walls in your home can cause issues. Thicker walls block more signal, thinner walls block less. Some materials will also do a better job than others will at stopping signal, so if you see a router with a range of 65 ft, know that it might not reach that far in your home. It could reach further – or not nearly as far. This is also why you get dead zones in your home – it’s a matter of geometry and materials.

On a router, latency refers to how long it takes for the router to send out and receive a signal. The longer it takes, the more delay there is between you sending and receiving data, which can introduce lag in video games and also makes video conferencing harder since the person you’re speaking with now has to contend with your delay and vice versa. If you’ve ever spent a call talking over someone because you don’t know they started talking a second ago, that’s latency.

For that reason, we recommend a latency below 40 ms. As low as you can get it is obviously preferable, but latency is another aspect of your internet connection that is hard to manage. Latency differs to every single place you connect to, and every ISP has its own latency they “add” because you have to connect to their service too. Latency creeps in from your ISP, from the site you’re requesting data from, from your router, and from your own onboard Wi-Fi antenna – and that’s just to name a few sources. If you’re gaming, you also have a delay introduced by your connection to game servers and the delay that exists on a hardware level when you input commands.
