The ASUS RT-BE82U Spends Its Wi-Fi 7 Budget on Ports

ASUS gives the RT-BE82U one 2.5G WAN port and four 2.5G LAN ports, per its spec sheet, and the manual lists them in rear-panel order: WAN, LAN 1 to 4, the USB 3.2 Gen 1 port, power input, power button, reset and WPS. There is no built-in modem, so it sits behind a fiber terminal or a cable modem.

A fiber or cable plan faster than a gigabit reaches the router through the WAN port at up to 2.5 Gbps. Inside the house, a NAS, a desktop with a 2.5G adapter and a second ASUS router for AiMesh can each take their own multi-gig socket, with no switch in between.

Five multi-gig sockets in one box is the point of this router. ASUS's own RT-BE92U goes further with a 10G WAN port, which a plan above 2.5 Gbps would need.

ASUS rates the 5 GHz radio at up to 5,764 Mbps and the 2.4 GHz radio at 688 Mbps, and the BE6500 name is the two added together. The 5 GHz figure needs four streams on a 160 MHz channel. Two-stream laptop and phone cards top out at half of it, so the extra streams pay off when several devices share the radio at once.

Without a 6 GHz radio there are no 320 MHz channels, which Wi-Fi 7 allows only in that band. ASUS lists dual-band Multi-Link Operation, which it describes as combining and switching between the 2.4 and 5 GHz bands.

A large or multi-level home may need a second AiMesh router, since one dual-band unit has to reach every floor on its own.

ASUS has published eight firmware builds for the RT-BE82U since March 2025, five of them in the last 12 months, according to its support page. The newest, 3.0.0.6.102_39446, is dated September 22, 2026, and its notes list a long run of security fixes, from the web interface to AiCloud and AiMesh.

Advisories dated October 1 and October 7 then disclosed six router vulnerabilities whose records cover the 3.0.0.6.102 branch this router runs. ASUS has not said which build fixes which flaw, and CISA recorded no known exploitation. Four of the six need someone already signed in as the administrator, so a strong admin password and remote web access left off close most of the gap.

The spec sheet lists AiProtection (malicious site blocking, two-way intrusion prevention, infected-device blocking), parental controls and WireGuard, OpenVPN and IPsec VPN servers. ASUS's material on the Best Buy listing says they come with no trial or subscription.

ASUS lists Dual WAN and automatic 4G or 5G tethering through the USB port, so a phone plugged into the router can take over as a failover line when the fixed connection drops.

The same port shares a drive over Samba or FTP and runs a media server. Time Machine is on the feature list too, but ASUS's spec page warns that from macOS 26 on, Time Machine can't create new backups on USB storage. Drives already set up for it keep working.
