Wi-Fi 5 vs Wi-Fi 6 Extender
Wi-Fi standard
The TP-Link Dual-Band WiFi 6 Extender (RE505X) uses the newer Wi-Fi 6 standard. This technology manages multiple devices more efficiently, reducing congestion in busy homes. The TP-Link AC1750 Dual-Band Wi-Fi Extender (RE450) relies on the older Wi-Fi 5 standard. While Wi-Fi 5 remains reliable for basic tasks, it lacks the advanced efficiency features of Wi-Fi 6. If you have many smart devices, the newer standard offers better performance. The RE505X provides a modern foundation for current networking demands.
Speed rating
Speed ratings differ between these two extenders. The AC1750 model boasts a combined speed of up to 1750 Mbps, split between 450 Mbps on the 2.4 GHz band and 1300 Mbps on the 5 GHz band. The RE505X offers a combined speed of up to 1.5 Gbps, with 300 Mbps on 2.4 GHz and 1201 Mbps on 5 GHz. The AC1750 has a slightly higher theoretical maximum on the 5 GHz band. However, the RE505X balances its bandwidth differently. Both provide ample speed for most home internet connections.
Coverage area
Coverage specifications are explicitly stated for the AC1750 extender. It claims to boost Wi-Fi coverage up to 2000 square feet. The data for the RE505X does not list a specific square footage rating. We cannot verify the exact coverage area for the RE505X from the provided specifications. Both units use external antennas to help spread the signal. You should place the AC1750 where it can effectively cover your target space based on its stated limit. The RE505X coverage depends on your specific environment.
Device capacity
The AC1750 extender specifies it can connect up to 32 devices simultaneously. This capacity covers most typical households with phones, laptops, and smart home gadgets. The RE505X data does not provide a specific number for maximum device connections. It mentions connecting more devices to your network, but lacks a hard limit. For users with exactly 32 devices, the AC1750 offers a clear specification. For smaller setups, both units should handle the load without issue. The lack of data for the RE505X makes direct comparison difficult here.
Physical dimensions
Size matters for placement near outlets. The AC1750 measures 6.4 inches in width, 3 inches in length, and 2.6 inches in height. It weighs 12.3 ounces. The RE505X is narrower at 2.48 inches wide, but taller at 6.23 inches high and deeper at 3.83 inches long. It is lighter at 8 ounces. The AC1750 has a wider footprint, which might block adjacent outlets. The RE505X is taller and slimmer. You need to check your outlet spacing to see which form factor fits your home better.
Compatibility features
The RE505X highlights OneMesh compatibility, allowing it to create a seamless network with compatible routers like the Archer A7. This feature helps you avoid switching networks manually. The AC1750 data does not mention OneMesh or specific mesh compatibility features. It notes compatibility with any router, gateway, or access point. The RE505X offers a specific ecosystem advantage for TP-Link router users. If you use a compatible router, the OneMesh feature simplifies your setup. Otherwise, both work as standard extenders.
Choose the right extender for your needs
User needing maximum coverage area
The TP-Link AC1750 Extender covers up to 2000 square feet. It connects up to 32 devices and offers 1750Mbps total speed. The three external antennas help boost signal strength across larger spaces. If you have a bigger home or many connected gadgets, this model provides the wider range you require.
Gamer or streamer wanting lower latency
The TP-Link Dual-Band WiFi 6 Extender uses the newer Wi-Fi 6 standard. This technology manages multiple devices more efficiently, reducing congestion. It supports speeds up to 1.5 Gbps. If you stream video or play games, the improved efficiency and higher speed rating help keep your connection smooth and responsive.
Person with compact living space
The TP-Link Dual-Band WiFi 6 Extender is smaller and lighter. It measures 6.23 inches in height and weighs only 8 ounces. This compact size fits easily into tight spots without taking up much room. If you have limited space for networking gear, this unit is a discreet and efficient choice.
