Dual-Band 802.11ac Wireless and Coverage
The Archer A7 runs two separate radios. The 5 GHz band uses 802.11ac, the Wi-Fi 5 standard, and is where phones, laptops and streaming boxes get their best speed near the router. The 2.4 GHz band uses 802.11b/g/n, reaching further and passing through walls more easily, but at far lower speeds and in a band shared with neighbours' networks, Bluetooth and microwave ovens. TP-Link rates coverage at up to 2,500 sq ft, and one owner in a house about that size found the signal robust in every room, while another now reaches the edge of the back yard. Speed and signal strength divide opinion more than coverage does, which is typical: the same router can feel fast in the living room and sluggish two floors away, particularly on 2.4 GHz. One owner recommends turning beamforming off, after finding it reduced throughput in their home; it is a setting worth trying both ways if speeds disappoint. Placement matters more than any setting, so put the router high and central, not in a cabinet or behind a TV.
