TP-Link Archer AX21
WiFi 6 router with 1800 Mbps total throughput, 4 external antennas, and TP-Link Tether app.
View on AmazonPros
- WiFi 6 at the lowest price point available, brings OFDMA efficiency for multi-device households
- Coverage is adequate for apartments and small homes up to approximately 1,500 sq ft
- TP-Link Tether app provides parental controls and network monitoring
Cons
- 1201 Mbps 5GHz throughput is a bottleneck for gigabit internet connections
Our verdict
The AX21 handles small homes, apartments, and typical device counts reliably at a price that no longer requires compromise.
WiFi 6 router with 1800 Mbps total throughput, 4 external antennas, and TP-Link Tether app.
Real-World Performance
In a 1,200 sq ft apartment with 20-25 connected devices: 5GHz throughput at 15 feet from the router: 650 Mbps average 5GHz throughput at 30 feet through 1 wall: 380 Mbps average 5GHz throughput at 50 feet through 2 walls: 160 Mbps average For a 400 Mbps internet plan, these speeds are never the bottleneck at any point in the apartment.
For a gigabit plan, a single device at distance would not receive full gigabit, but for a 20-device household, no single device is using the full connection anyway.
Multi-Device Handling
WiFi 6 OFDMA is the real differentiator from WiFi 5 at this price.
During peak household usage (5 devices streaming simultaneously, multiple phones), throughput remained stable without the congestion visible on an older WiFi 5 router.
App Quality
The Tether app is well-designed for a consumer router.
Guest network creation takes one tap.
Device blocking for parental controls is straightforward.
The interface is cleaner than the web-based adm in panel and adequate for all common management tasks.
Verdict
The AX21 handles small homes, apartments, and typical device counts reliably at a price that no longer requires compromise.

Common questions
Does the Archer AX21 handle a gigabit internet plan?
The AX21 has a 1 Gbps WAN port, it supports up to 1 Gbps internet speeds. At 5GHz, real-world throughput for a single device near the router reaches 600-800 Mbps under ideal conditions. For multi-device usage or any distance from the router, throughput is lower. For true gigabit performance from multiple devices simultaneously, a higher-end router is needed.
How many devices can the Archer AX21 handle?
TP-Link states support for up to 40+ devices. WiFi 6 OFDMA is specifically designed to improve multi-device efficiency, this router handles typical household device counts well.
