Dual-band AC750 router for home use

The TP-Link Archer C20 delivers simultaneous 2.4 GHz 300Mbps and 5 GHz 433Mbps connections for 733Mbps total bandwidth. It supports Wi-Fi 5 and IPv6 for modern home networks. Three external antennas provide omnidirectional coverage across typical living spaces. It suits households needing basic wireless access for browsing and streaming.

Simple browser or app setup with WPS

Configuration uses a web interface or the Tether app on Windows, Mac, Linux or UNIX systems. A WPS button allows quick device pairing without password entry. The router requires an existing cable, DSL or fibre modem for internet access. Only 10/100M Ethernet ports are provided, limiting wired throughput to 100Mbps. No USB storage or printer sharing is supported despite the USB 2.0 interface.

Steady throughput on both bands under load

The 2x2 MIMO design maintains stable links during sustained transfers on either frequency. Receiver sensitivity figures show consistent performance at various modulation rates up to VHT80 MCS9. Transmitted power stays within CE limits of 20 dBm on 2.4 GHz and 23 dBm on 5 GHz. The 9V 0.6A supply handles continuous operation without thermal throttling.

Questions about this item

How can I confirm the Archer C20 is broadcasting both the 2.4 GHz and 5 GHz bands after setup?

Log into the web interface or Tether app and verify that the 2.4 GHz radio shows up to 300 Mbps and the 5 GHz radio shows up to 433 Mbps with both SSIDs active.

What comes in the box with the Archer C20 and what must I provide myself?

The package includes the router, three external antennas, a 9 V / 0.6 A power adapter and an Ethernet cable; you must supply a cable, DSL or fibre modem and an active internet subscription.

The specs list AC750 with 300 Mbps on 2.4 GHz and 433 Mbps on 5 GHz — which version should I choose?

There is only one hardware version of the Archer C20 AC750; the dual-band rates of 300 Mbps and 433 Mbps are fixed, so no capacity choice is required.
