The Archer BE900 is the far more powerful radio: a quad-band Wi-Fi 7 flagship with a dedicated 6 GHz band, twelve internal antennas, dual 10G ports and an SFP+ cage, all of which dwarf the dual-band RT-BE86U's single 10G port. The RT-BE86U answers with AsusWRT's enthusiast toolkit, including a command line interface the Archer BE900 does not offer. Go with the Asus RT-BE86U for an affordable, well-rated router with a 10G port and deep configurability, or the TP-Link Archer BE900 if maximum Wi-Fi 7 airtime and a 6 GHz band matter more than price.
