Wi-Fi speed classiThe maker's class name, e.g. BE19000 or AXE11000. It adds up the top link rates of all radios. No single device reaches it. A Wi-Fi 6E class starts with AXE, also when the maker writes AX, so eero's AX5400 is AXE5400. The class is not the model number, so GL.iNet's GL-AXT1800 is AX1800.

AC12001Maker product pagetp-link.com/us/home-networking/wifi-router/archer-a54Read 15 October 2026WiFi Speeds: AC1200, 5 GHz 867 Mbps (802.11ac) and 2.4 GHz 300 Mbps (802.11n).

Source1Maker product pagetp-link.com/us/home-networking/wifi-router/archer-a54Read 15 October 2026The page prints rates but no stream counts per band or channel widths. 300 Mbps is the 802.11n rate of 2 streams at 40 MHz and 867 Mbps is the 802.11ac rate of 2 streams at 80 MHz. The MU-MIMO text speaks of two simultaneous data streams. The reception sensitivity list names 11n HT40 and 11ac VHT80 channels. The 2.4 GHz radio is Wi-Fi 4 (802.11n) and the 5 GHz radio is Wi-Fi 5 (802.11ac). These values are worked out from the published rates and are not printed by the maker as stream counts.

Wi-Fi featuresiFeatures the maker names for the product. Band steering puts all bands under one network name and moves devices between them, e.g. Smart Connect. Band steering over only some of the bands, such as 2.4 and 5 GHz on a tri-band router, counts. AFC is Automated Frequency Coordination, which allows standard power on 6 GHz.
