8.5/10
The ASUS RT-BE58U is a dual-band BE3600 Wi-Fi 7 router with one 2.5Gbps port, four external aerials and ASUS's AiMesh and security tools. It suits homes with fast fibre that want a full feature set at a modest price.
One 2.5Gbps WAN/LAN port for full-fibre plans above 1Gbps
AiMesh lets you add other ASUS routers as nodes
Network security, parental controls and a separate IoT network included free
USB port for storage or a mobile tethering backup
Keep in mind
Only one 2.5Gbps port, so wired devices share gigabit LAN sockets
No 6GHz band
ASUS's app has many settings and takes longer to learn than TP-Link's

About the ASUS RT-BE58U
The RT-BE58U is a dual-band Wi-Fi 7 (802.11be) router rated at BE3600. ASUS quotes up to 2882Mbps on 5GHz and 688Mbps on 2.4GHz, from four external antennas arranged 2x2 on each band. There is no 6GHz radio. It supports 160MHz channels, MLO and 4K-QAM, and it also works with older Wi-Fi 6, 5 and 4 devices.
Wired connections are one 2.5G WAN/LAN port, one 1G WAN/LAN port and three 1G LAN ports. A single USB 3.2 Gen 1 port handles storage or a 4G/5G mobile tethering backup. The router has a 2.0GHz quad-core processor, 1GB RAM and 256MB flash. It has no built-in modem, so it needs a fibre ONT or a separate modem from your provider. It can run as a router, access point or media bridge.
The software is the main draw. AiProtection Pro and ASUS Network Security are included without a subscription, along with parental controls, age-based profiles and scheduling. Smart Home Master can create separate IoT, Kids and VPN networks. WireGuard and OpenVPN are supported, and AiMesh lets you add other ASUS routers as nodes under one network name. Setup runs through the ASUS Router app or a browser. In the box: the router, an Ethernet cable, a power adapter, a quick start guide and a warranty card.
What owners report about the ASUS RT-BE58U
Owner feedback for this exact model is thin on UK sites, so this draws mainly on a Finnish retailer's reviews and a few forum threads. Owners like the speed against older routers and ISP-supplied boxes, and they describe the connection as stable. Setup through the app is called easy, and range is judged fine for a typical flat or house.
The complaints are fairly consistent. Some owners have had devices drop off until the router is restarted. The web interface looks dated to some, and parts of the app feel unfinished. Range falls away outdoors and in outbuildings. A few dislike the look, and wish it came in white.
Independent testers add that the 2.4GHz range is modest and that the settings are deeply nested in the app. Anyone hoping to flash OpenWrt should know a forum thread suggests it is unlikely to be supported, because of the Broadcom chipset. That is one user's view, not an official position.
Who the ASUS RT-BE58U suits
It suits a small to medium home with a full-fibre line, a few dozen devices and an interest in parental controls, a separate IoT network or a VPN. The 2.5Gbps WAN port handles plans above 1Gbps, and AiMesh is useful if you already own ASUS routers. Testers found it fast enough for most homes.
Look elsewhere if you have several wired devices that need multi-gig speeds, since only one port is 2.5Gbps. The TP-Link Archer BE550 or MERCUSYS MR47BE add a 6GHz band and more 2.5Gbps ports. The TP-Link Archer BE3600 has 2.5Gbps WAN and LAN ports, and the ASUS RT-BE86U is the stronger choice for larger homes. On copper broadband (VDSL), the AVM FRITZ!Box 7530 AX UK has a modem built in.
Questions about the ASUS RT-BE58U
Is the ASUS RT-BE58U a good router?
Yes, for most homes. Expert Reviews found it fast enough for home use and praised its full firmware, though it noted faster Wi-Fi 7 routers exist and that it has no 6GHz band.
Is the ASUS RT-BE58U a modem?
No. It has no built-in modem, so it connects to your fibre ONT or a separate modem. It can use a USB 4G/5G device as a backup connection.
Are ASUS routers better than TP-Link?
Not across the board. ASUS tends to offer more settings and free security tools, while TP-Link's app is simpler to learn. The RT-BE58U follows that pattern, with its app taking longer to get used to.
How do I set up my ASUS RT-BE58U router?
Connect the 2.5G port to your ONT or modem, power it on, then open the ASUS Router app or the browser interface. Expert Reviews found the app detected the router wirelessly and prompted for a network name and security settings, then the router rebooted.
Can I run OpenWrt on the ASUS RT-BE58U?
Probably not. One OpenWrt forum user expects it will never be supported because of the Broadcom chipset, though this is an opinion rather than an official statement.

Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 19 models for this guide before settling on these ten.
Brands can't pay to be included or to move up. We last checked these picks in November 2026.
