Asus RP‑AX58
$4 under your budget
The best value in Wi-Fi 6 extenders — 115 ft of range, the longest any lab tested, for less than the top pick and with AiMesh for Asus routers.

■ The catch — co-equal billing, always
Its edge is range, not speed. Peak throughput trails the RE715X (~250 vs 300+ Mbps in BroadbandNow's tests), and the AiMesh roaming that makes it shine only works with an Asus router — pair it with another brand and you get a separate network name.
Dealbreaker? Runner-up №1 (RE715X) is faster for ~$4 more ↓
■ Every product has a catch. Verdicts that hide it are how bad buys happen.
Runners-up — if your needs differ
Adjacent verdicts — same method
Traps — this verdict avoids
The bandwidth tax
A single-radio extender receives and rebroadcasts on the same band, so it halves the bandwidth at your device. A mesh system with dedicated backhaul avoids it but costs 2-4x more — Ethernet or a backhaul-band model (EAX80) is the cheaper fix.
Wi-Fi 7 without a Wi-Fi 7 router
The RE655BE's 720 Mbps headline only lands on a Wi-Fi 7 router. Paired with a Wi-Fi 6 router it drops to Wi-Fi 6 speeds, so the ~$180 buys nothing over an $80 Wi-Fi 6 extender.
Mismatched brands split your network
OneMesh, AiMesh, and Smart Roaming only roam seamlessly with a same-brand router. Pair an extender with another brand and you get a separate SSID you switch between by hand.
