The TP-Link RE220 WiFi Extender supports both 2.4GHz and 5GHz frequencies. Based on the manufacturer's description, it can hit speeds of up to 300Mbps on the 2.4GHz band and 433Mbps on the 5GHz band, giving you a combined total of around 750Mbps. This makes it quite versatile for different tasks, from browsing the web to streaming HD videos.

One thing to keep in mind is that the RE220 creates separate extended networks for each band, usually adding 'EXT' to your original network name. This means you might need to switch between these extended networks and your main one as you move around your house. Our research shows that some people find this a bit inconvenient.

For example, one person mentioned that they had to manually switch networks to keep a strong connection, which wasn’t as smooth as they hoped.

Even with the manual switching, a lot of folks still find the TP-Link RE220 improves their WiFi coverage effectively. Setting it up is pretty straightforward, especially with the TP-Link Tether app that guides you through the process. According to our data, most people notice a big improvement in WiFi coverage, particularly in areas that were previously dead zones.

So, if you need to extend your WiFi range on both 2.4GHz and 5GHz bands and don’t mind the occasional manual switch between networks, the TP-Link RE220 is a solid choice. It's easy to set up and can help get rid of those pesky dead zones in your home.

The TP-Link RE220 WiFi Extender can handle up to 32 devices at once, including any main or guest networks you set up.

According to the manufacturer's description, you can use the Tether app to easily manage these connections and tweak settings like guest networks.

From what we've found, most folks agree it's pretty easy to set up and does a solid job at boosting your WiFi coverage.

Yes, the TP-Link RE220 works with most routers.

Here's the deal though: it creates a new network with a different name, typically adding ‘_EXT’ to your original network name (like ‘HomeWiFi_EXT’). So, you’ll need to switch to this new network for the best performance, which can be a bit inconvenient.

According to our research, this is just how the TP-Link RE220 (AC750) operates. It extends your WiFi signal by making a separate network rather than seamlessly expanding your current one under the same name. Thus, your devices need to jump over to the extended network when you're farther from the main router.

If you prefer a setup where your devices automatically switch to the strongest signal without you doing anything, you might want to look into mesh WiFi systems or WiFi extenders that support OneMesh technology.

The TP-Link RE220 is OneMesh compatible, but you'll need a matching TP-Link router like the Archer A7 to create a unified network with a single name.

So, in short, the TP-Link RE220 does a solid job extending WiFi coverage, but just know that it usually means connecting to a new network name for the best signal.

For a smoother experience, OneMesh-compatible devices or mesh networks could be better options.
