ASUS RT-AX55 (WiFi 6/Standalone Router/Budget Dual-Band/AX1800/AiMesh Compatible) Review
ASUS RT-AX55 budget dual-band WiFi 6 router with AX1800 speed class and AiMesh compatibility for future expansion.
RT-AX55 is ASUS's entry point into WiFi 6, and it's honest about what it is: a small apartment or single-floor router that happens to support the newer standard's efficiency gains without the price of a flagship. The real long-game value is AiMesh compatibility — buy one now, add a second AiMesh-compatible ASUS unit later if the space grows, without replacing what you already own.
Who It's Built For
Apartment dwellers and small households wanting an affordable entry into WiFi 6, with the option to mesh-expand later.
Comparison to Alternatives
Against the TP-Link Archer AX21, RT-AX55 sits in the same budget WiFi 6 tier, with ASUS's AiMesh expandability as the main long-term differentiator over TP-Link's OneMesh. Compared to ASUS's own RT-AX86U Pro, RT-AX55 gives up gaming features and raw throughput for a substantially lower price suited to smaller spaces.
