Best WiFi Extenders Summary

Extenders vs. Alternatives

Extenders are generally not recommended for optimal performance. Hardwiring an Access Point is preferred for maintaining performance.
An alternative to extend WiFi is using a WiFi Router in bridge mode, effectively turning it into an extender.

Kivaj RangeMax Pro Booster: User pointed out using this booster with 1200mbps.
TP-Link RE-650: This extender received praise for its performance with dual-band wireless and high transfer rates.
TP-Link EAP610: Recommended over extenders due to being an Access Point with better performance.
TP-Link OneMesh Devices: Perfect for a TP-Link router, highly recommended for home users.
Netgear Nighthawk AC1900 Router: User praised it for reliable service.
Ubiquiti: Suggested for enterprise-level performance.

Ethernet cables are highly recommended for optimal performance.
MoCA adapters can be a good solution for superior connectivity via coaxial cables.
Mesh networks are a better alternative to extenders for better signal quality.
Powerline adapters can be considered, but may have sporadic connection issues based on electrical wiring.

Setting up a secondary Access Point hardwired to the main router for better signal.
Considering higher-gain antennas for routers to improve signal strength.
Orbi Mesh systems and high-end Mesh routers are praised for reliability and good coverage.
For practical setups in apartments or specific scenarios, WiFi extenders can provide decent results.

The consensus is to prioritize solutions such as hardwiring, MoCA, mesh networks, and access points over traditional WiFi extenders.
The choice of product and solution depends on individual needs, infrastructure, and budget constraints.
