Wi-Fi repeaters are a very interesting complement to extend Wi-Fi coverage in our home easily. If with our main Wi-Fi router it is not enough to have coverage throughout our home, Wi-Fi amplifiers are the cheapest and most effective device you can buy to complement it with your router. There are a large number of Wi-Fi repeater models with different technical characteristics, the main manufacturers of Wi-Fi amplifiers are D-Link, NETGEAR, AVM FRITZ !, ASUS, TP-Link among other manufacturers.
To choose a good Wi-Fi repeater or amplifier, we must look at several very important aspects:
- Wi-Fi version and Wi-Fi class : To have the best wireless performance, you need to have a current Wi-Fi standard, the latest wireless standard is Wi-Fi 6 (also known as Wi-Fi AX), However, today there are very few Wi-Fi repeaters with the latest standard, so the most normal thing is to find amplifiers with Wi-Fi 5, in addition, these equipment are cheaper than the newer ones. The most important thing is the kind of Wi-Fi that a Wi-Fi repeater has, that is, the combined speed of the different Wi-Fi frequency bands. The higher the Wi-Fi class number (for example, AC3000), the higher overall performance we will get on the Wi-Fi network.
- Dedicated trunk link : Wi-Fi repeaters that are simultaneous triple band, allow configuring a 5GHz frequency band specifically for interconnection with the router. This is essential to achieve the best wireless performance, and also wired, since the dedicated frequency band is not shared with customers and we will achieve higher Wi-Fi speeds.
- Roaming Wi-Fi and band steering : Currently there are Wi-Fi repeaters that integrate perfectly with routers from the same manufacturer, to have Wi-Fi roaming and band steering, as if it were a complete Wi-Fi Mesh system. D-Link, ASUS and AVM FRITZ! They just have repeaters with this feature, then we have NETGEAR that has the 802.11k standard and it does not matter what router you use.
- Ethernet ports : if the Wi-Fi repeaters incorporate one or more Gigabit Ethernet ports, it means that their firmware allows them to also be used as APs, and even connect it to the main router via cable to have Wi-Fi roaming and band-steering with better performance wireless Wi-Fi. High-end Wi-Fi repeaters typically incorporate 2 or more Gigabit Ethernet ports.
- Firmware : Firmware is always the brain of the Wi-Fi repeater, having optimized firmware on a Wi-Fi amplifier is essential, but it is also very important that they have a large number of configuration options. For example, we can configure the trunks specifically, activate the Cross-band to get more Wi-Fi performance in certain scenarios, and even activate the Wi-Fi networks of guests, Wi-Fi programmer and many other configuration options that we can perform. . The most important thing currently for repeater firmwares is whether they allow Wi-Fi roaming and band-steering.
