What the differences mean

Wi-Fi bands

The Asus RT-BE88U is dual-band, 2.4 GHz plus one 5 GHz radio, with no 6 GHz at all. The TP-Link Archer BE900 adds a second 5 GHz radio and a 6 GHz band, so it has more airtime to spread devices across. If you have 6 GHz laptops and phones, that is the difference you would feel.

Peak wireless speed

The TP-Link Archer BE900 is rated at 24.4 Gbps and the Asus RT-BE88U at 7.2 Gbps. Those are combined figures across bands, not what one device gets, but they show the BE900 is the flagship radio of the pair.

Wired ports

The Asus RT-BE88U has ten LAN ports, including a 10G RJ45, a 10G SFP+ and four 2.5G. The TP-Link Archer BE900 has eight, with two 10G RJ45, an SFP+ and four 2.5G. For a rack of NAS boxes and switches, the extra LAN count on the Asus goes further.

WAN redundancy

The Asus RT-BE88U lists multi-WAN and WAN failover, so a second internet line can take over when the first drops. The TP-Link Archer BE900 lists neither, so it suits a single connection.

Management tools

The Asus RT-BE88U has a command line and Time Machine backup support. The TP-Link Archer BE900 has neither and is managed through the web page and app, which is simpler for a household and thinner for a tinkerer.

What owners say

Owners of both routers talk about the same two things: multi-gig wired ports that make them a good match for a fast plan or a NAS, and a mixed record on reliability. Asus RT-BE88U owners single out the port layout, easy setup, free AiProtection security with no subscription and Asuswrt-Merlin firmware support, while some report weak signal or connectivity quirks and say value is divided. TP-Link Archer BE900 owners single out coverage that reaches dead zones in larger multi-story homes, app setup that takes minutes and the separate IoT network, while a vocal minority describe random disconnects or a reboot cycle that survives a factory reset. They also note there is no command line, no speed test and no multi-WAN on the TP-Link.
