DSL-AC51
This year marks the 10th consecutive year that ASUS has won Readers’ Choice Best Wireless Networking Brand. And they’ve managed to increase their lead from 33% for the 2022 Awards to 39% in 2023. It is a stronghold for ASUS as a consumer brand that focuses on performance and adoption of the latest standards, especially with their ROG line of gaming routers.
Today, they’re well known not just for superior wireless performance, but also as one of the few brands that continue to push the latest in standards, security, advanced user customisation and building a robust networking ecosystem through AiMesh functionality to enable compatible ASUS routers to work together in a single SSID.
ASUS’ popularity is most likely due to their focus on powerful hardware with cutting edge networking features across their Wi-Fi 6 range from the flagship ROG Rapture GT-AX11000 to the RT-AX86U.
With 29% of the votes this year, ASUS has now captured this Readers’ Choice award for Best Wireless Networking Brand for seven straight years.
