AX3000 vs AX1800 Extender Specs
Speed Rating
The TP-Link RE700X carries an AX3000 rating, while the NETGEAR EAX15 is rated AX1800. This number reflects the combined maximum theoretical throughput across both frequency bands. The AX3000 model lists speeds up to 3 Gbps, split between 2402 Mbps on the 5 GHz band and 574 Mbps on the 2.4 GHz band. The AX1800 model offers lower combined bandwidth, typical for its class. Higher ratings generally support more data-intensive tasks simultaneously. If you stream 4K video or game on multiple devices, the higher throughput of the AX3000 extender provides more headroom. The AX1800 is sufficient for standard browsing and HD streaming but may bottleneck under heavy load.
Wi-Fi Standard
Both the TP-Link RE700X and the NETGEAR EAX15 support the Wi-Fi 6 standard. This means both devices use the same underlying technology for data transmission. Wi-Fi 6 improves efficiency in crowded networks and supports newer devices like AX phones and laptops. Since both units operate on this standard, you get similar benefits regarding latency and connection stability for compatible clients. There is no difference in the core protocol version between these two extenders. You do not need to choose one for better Wi-Fi 6 support over the other. The performance difference comes from their speed ratings and hardware capabilities, not the standard itself.
Frequency Band
Both extenders utilize dual-band connectivity, operating on both 2.4 GHz and 5 GHz frequencies. The 5 GHz band offers faster speeds and less interference, ideal for streaming and gaming. The 2.4 GHz band provides better range and wall penetration, suitable for IoT devices and distant areas. Since both products offer dual-band support, they can broadcast two separate networks or combine them into one SSID. This allows you to connect devices to the band that best suits their needs. Neither product offers tri-band capability. You get identical frequency band options from both the TP-Link and NETGEAR units, ensuring similar flexibility in network setup.
Ethernet Ports
Each extender includes a single Ethernet port for wired connections. The TP-Link RE700X specifies a Gigabit Ethernet port, ensuring high-speed wired connections for devices like desktops or smart TVs. The NETGEAR EAX15 lists one Ethernet port but does not explicitly state the speed rating in the provided data. Assuming standard implementations, it likely supports Gigabit speeds as well. This port allows you to connect wired devices directly to the extender, bypassing wireless limitations. Both units provide the same utility for wired backhaul or device connection. You can attach one wired device to either extender without significant difference in functionality.
Form Factor
The physical design differs significantly between the two models. The NETGEAR EAX15 features a compact wall plug form factor, plugging directly into a wall outlet. This saves desk or shelf space and allows placement in any standard outlet. The TP-Link RE700X is a larger, standalone unit measuring approximately 5.87 inches in length. It requires a dedicated outlet or location but may house more internal components. The NETGEAR design is more discreet and space-efficient. The TP-Link design may offer better heat dissipation due to its larger surface area. Your choice depends on whether you prioritize space saving or potentially more robust hardware.
Which Extender Suits Your Home
Users needing maximum wireless throughput
The TP-Link RE700X offers an AX3000 speed rating with up to 3 Gbps combined throughput. Its four internal amplifiers help reach hard-to-cover areas more effectively than the lower-rated competitor. If you require higher theoretical speeds for bandwidth-heavy tasks, this model provides the superior data transfer capabilities defined by its specifications.
Buyers wanting space-saving wall installation
The NETGEAR EAX15 features a compact wall plug form factor that plugs directly into an outlet. This design saves desk or shelf space, making it ideal for tight corners or hallways. While it has an AX1800 speed rating, its physical footprint and mesh-compatible design suit users prioritizing discreet placement over raw speed.
Those with compatible OneMesh routers
The TP-Link RE700X is explicitly OneMesh compatible, allowing it to create a seamless network with supported routers like the Archer AX21. This ensures you never have to switch networks manually. If your existing setup includes a compatible TP-Link router, this extender integrates directly to provide consistent coverage without manual network switching.

Frequently asked questions
Does an AX3000 extender work with an AX1800 router?
Yes, you can mix these speed ratings. Both devices use the Wi-Fi 6 standard, ensuring backward compatibility. The extender will connect to your router, though the overall network speed may be limited by the slower component. This setup allows you to expand coverage without replacing your existing hardware immediately.
Is AX3000 significantly faster than AX1800 in real use?
The AX3000 rating indicates a higher theoretical maximum throughput. The TP-Link RE700X lists speeds up to 3 Gbps, while the NETGEAR EAX15 offers lower combined bandwidth. In practice, you may see better performance for multiple high-bandwidth devices on the AX3000 model, especially when connecting to the wired port simultaneously.
Which extender is better for a small apartment?
The NETGEAR EAX15 is often better for small spaces due to its wall-plug design. It saves floor space and provides sufficient Wi-Fi 6 coverage for single-room extension. The TP-Link RE700X is larger and may be overkill for small areas, offering more power than a compact apartment typically requires.
Can I connect a gaming console to either extender?
Yes, both extenders include an Ethernet port for wired connections. You can plug a gaming console directly into the port for a stable link. This bypasses wireless interference. The TP-Link RE700X and NETGEAR EAX15 both support this wired backhaul, ensuring consistent latency for online gaming or streaming.
Do I need to buy a new router for AX3000?
No, you do not need a new router. The TP-Link RE700X works with existing routers that support Wi-Fi 6 or earlier standards. It acts as a range extender, not a replacement. Your router handles the main connection while the extender boosts the signal to distant areas of your home.
Is the TP-Link RE700X hard to install?
Installation is straightforward for most users. You plug it into a wall outlet and use the companion app or web interface to connect it to your existing network. The device supports standard Wi-Fi 6 security protocols. You can place it halfway between your router and the dead zone for optimal results.
Does the NETGEAR EAX15 support 5GHz bands?
Yes, the NETGEAR EAX15 is a dual-band device. It operates on both 2.4GHz and 5GHz frequencies. The 5GHz band offers faster speeds for closer devices, while the 2.4GHz band provides better range through walls. This dual-band capability helps balance speed and coverage for different devices in your home.
