Question about TP-Link Deco X50-5G (1-pack)

Yes, a pure bridge mode is possible so that you can leave the WiFi to your ASUS Mesh. The Deco X50-5G supports bridge mode, in which it acts purely as a modem and does not perform any mesh or router functions. Note that in bridge mode, no mesh functionality with other Deco devices and no firmware updates are possible. It is important to note that this function is primarily available for hardware version V1 with firmware 1.1.5; there is currently no clear support or date for Bridge Mode for the V2 version.
