Asus RT-BE88U Review: A Port-Packed Dual-Band Wi-Fi 7 Router for Wired-First Homes
Ten ports including two 10G and an SFP+ cage, a deep feature set and free security, in a dual-band Wi-Fi 7 router that skips the 6 GHz band to hit a friendlier price.
The RT-BE88U is a dual-band Wi-Fi 7 (BE7200) router built around an unusually rich wired port layout: two 10G ports (one RJ45, one SFP+) plus four 2.5G and four Gigabit ports. It targets buyers who care more about multi-gig wired connectivity, a deep AsusWRT feature set and free security than about the 6 GHz band, which this model omits. Owners praise its easy setup, port selection, fast processor and stability, while noting that wireless performance and value are a bit polarizing and that you need some networking know-how to get the most from it. For a wired-first home or small business on a fast plan, it is a capable, no-subscription pick at a lower price than tri-band Asus flagships.

Who is the Asus RT-BE88U for?
The RT-BE88U is a dual-band Wi-Fi 7 router covering 2.4 GHz and 5 GHz, rated BE7200 (up to 7.2 Gbps) with a 2.6 GHz quad-core processor, 2GB of RAM and four external antennas. Crucially, it has no 6 GHz band, so it trades Wi-Fi 7's newest spectrum for a lower price and a standout wired layout. That layout is the headline: ten ports in total, including a 10G RJ45 port, a 10G SFP+ cage, four 2.5G ports and four Gigabit ports, plus USB 3.2. It suits people who wire a lot (NAS, switches, gaming PCs, a small business) and want AsusWRT's depth, VLAN-style network separation, VPN and free AiProtection, rather than buyers chasing the absolute fastest 6 GHz wireless.
What buyers love
The most consistent praise is the port selection and features. Owners repeatedly call out the two 10G ports and the overall high-speed wired layout as rare and valuable, and several use every port for a wired backbone. Setup is described as easy, and long-time Asus owners value the stability, fast processor, generous RAM and the promise of long-term firmware support. The built-in feature suite is a recurring highlight: adaptive QoS for gaming, multiple separate networks for security, a full VPN client and server suite, and free AiProtection security with no subscription. Enthusiasts also appreciate Asuswrt-Merlin firmware support, which several say made their setup rock solid. Many describe strong Wi-Fi coverage for a dual-band router, and buyers upgrading from older Asus models find it a practical, capable all-in-one.
What to know before you buy
The defining trade-off is the missing 6 GHz band: as a dual-band Wi-Fi 7 router, the RT-BE88U cannot use 6 GHz, so buyers who want the fastest, cleanest wireless spectrum (and who have very fast internet and 6 GHz clients) should look at a tri-band model instead. Reception is a little polarizing: reliability is the most-discussed topic and it is mixed, with some owners reporting weak signal or connectivity quirks and a few needing initial configuration time before things settled. Value opinions are divided too, as this is not a cheap router. It also rewards networking knowledge; casual users may not tap its full potential. As with other Asus routers, there is no built-in internet speed test.
Is the Asus RT-BE88U worth it?
For a wired-first home or small business that will actually use its 10G and 2.5G ports and AsusWRT's deeper features, the RT-BE88U offers a lot of connectivity and a free security and VPN toolkit for less than tri-band Wi-Fi 7 flagships, backed by a 3-year warranty. It makes the most sense when you value ports and features over the 6 GHz band, and are comfortable tuning a network. Buyers who want 6 GHz Wi-Fi 7 or a simple plug-and-play experience should weigh those points first.
Frequently asked questions
Does the Asus RT-BE88U have a 6 GHz band?
No. It is a dual-band Wi-Fi 7 router using 2.4 GHz and 5 GHz only. If you specifically want the 6 GHz band, choose a tri-band model.
What wired ports does it have?
Ten in total: one 10G RJ45 port, one 10G SFP+ port, four 2.5G ports and four Gigabit ports, plus a USB 3.2 port. It is one of the most port-rich routers in its class.
Does it require a subscription for security or VPN?
No. Asus includes AiProtection security and a full VPN client and server suite (OpenVPN, WireGuard, PPTP, L2TP/IPSec) at no extra cost.
Can I use it in a mesh network?
Yes. It supports Asus AiMesh, so you can pair it with other AiMesh-compatible Asus units for wider coverage.
Is it a good router for gaming?
It offers adaptive QoS, a gaming port and Asus's gaming acceleration tools, and its strong wired ports suit gaming PCs and consoles, though it lacks the 6 GHz band of higher-end models.
