ASUS RT-AX86U vs TP-Link Archer AX21

Both are real gaming router options from our gaming routers guide. Specs below are taken from each product's own listing — we don't run benchmarks or invent performance numbers.

ASUS RT-AX86U

WiFi 6 router with a dedicated gaming port, mobile game mode and port forwarding tools for prioritizing game traffic.

Specs

WiFi 6 (AX5700), dual band
2.5G WAN/LAN port
Dedicated gaming port
Mobile Game Mode
Port forwarding tools
AiMesh compatible

✓ Best for

Busy households where game traffic competes with streaming/downloads — the QoS and gaming port exist specifically for prioritisation.

⚠ The tradeoff

None of this beats a wired Ethernet run for latency. If you can run a cable to your gaming PC, that matters far more than the router tier.

TP-Link Archer AX21

Budget-friendly WiFi 6 dual-band router — a solid entry point if you mainly need better coverage and multi-device handling.

Specs

WiFi 6 (AX1800), dual band
Gigabit ports
EasyMesh compatible
Works with Alexa
4 antennas

✓ Best for

Upgrading from an old WiFi 5 router — the biggest gain is handling many connected devices at once, not raw peak speed.

⚠ The tradeoff

No 2.5G port and fewer gaming-specific QoS tools than higher-tier routers. Fine for typical broadband speeds.
