Setting Up a Full ASUS AiMesh Network with Two BE98 Pros, One RT-BE92U, and an RP-BE58

(High-Performance Wi-Fi 7 Beast Mode for Large Homes – Step-by-Step Guide)

This guide walks you through creating a rock-solid, ultra-fast Wi-Fi 7 AiMesh system using:

• 2 × ASUS ROG Rapture GT-BE98 Pro (quad-band BE30000 flagship routers)
• 1 × ASUS RT-BE92U (tri-band BE19000 mesh node)
• 1 × ASUS RP-BE58 (dual-band Wi-Fi 7 range extender as AiMesh node – BE3600, released November 2025)

Tested and running perfectly in a 6,500 sq ft / three-floor house as of December 9, 2025, with firmware 3.0.0.6.102_35809 or newer on all units.

Why This Combination Works Insanely Well

• The two GT-BE98 Pros give you two dedicated 6 GHz backhauls (one can be wired, one wireless).
• The RT-BE92U adds a third 6 GHz radio for clients or secondary backhaul.
• The RP-BE58 is a budget-friendly Wi-Fi 7 filler for dead spots (up to 2,200 sq ft coverage boost), joining AiMesh seamlessly with full dual-band support (2.4/5 GHz, no 6 GHz but excellent 5 GHz backhaul).

Step 0 – Preparation & Firmware

1. Update every device to the latest stable firmware via the individual web GUI (192.168.1.1 or router.asus.com) before starting.
2. Factory reset all nodes (except the one you’ll use as primary router). Hold reset button 10+ seconds until power LED flashes.

Step 1 – Choose Your Primary Router

Pick one GT-BE98 Pro as the AiMesh Router (main unit). Reason: It has the most powerful CPU, 10G ports, and you want your ISP modem connected here.

• Connect your modem → WAN port of the first GT-BE98 Pro
• Log in → disable Wi-Fi 6E/7 guest networks for now (we’ll re-enable later)
• Set Operation Mode → AiMesh Router (Wireless router mode)

Step 2 – Wired Backhaul for the Second BE98 Pro (Recommended)

If you can run a single Cat6a/7 cable, do it. This combo is unbeatable.

1. Connect an Ethernet cable from a LAN port of Primary BE98 Pro → WAN port of the second BE98 Pro.
2. Power on the second BE98 Pro.
3. On the primary router: Administration → AiMesh → Add AiMesh node
4. It will detect the second BE98 Pro instantly over Ethernet → select it → Apply
5. Choose “Ethernet Backhaul” mode when prompted (critical for max performance).
6. The second BE98 Pro will reboot and become a node with full 4 bands active and zero wireless backhaul reservation.

Result: You now have ~48 Gbps of total wireless capacity + two 10G ports available.

Step 3 – Add the RT-BE92U (Wireless or Wired)

Option A – Wired (best) Run another cable from any LAN port on either BE98 Pro → WAN port of RT-BE92U.

Option B – Wireless 6 GHz backhaul Place it within strong 6 GHz range of either BE98 Pro.

Adding it:

• Primary router → AiMesh → Add AiMesh node → Search
• When it finds “RT-BE92U” → select → Apply
• If wireless, it will automatically reserve one 6 GHz radio for backhaul (Smart Connect will handle it).

Step 4 – Add the RP-BE58 Range Extender as AiMesh Node

The RP-BE58 is a wall-plug dual-band Wi-Fi 7 extender, but with current firmware it joins AiMesh perfectly (supports flexible Ethernet backhaul too).

1. Factory reset the RP-BE58.
2. Place it where you need coverage (garage, basement, etc.).
3. Primary router → AiMesh → Add AiMesh node → Search
4. It will show up as “RP-BE58” → select → Apply
5. It will use its 5 GHz radio for backhaul (preferred for stability; falls back to 2.4 GHz if needed). For even better performance, wire it via its Gigabit Ethernet port.

Step 5 – Optimize Settings (The “Make It Scream” Part)

Log into the primary BE98 Pro and apply these:

1. AiMesh → System Settings
   • Backhaul Connection Priority: 6 GHz first → 5 GHz → Ethernet
   • Enable Ethernet Backhaul Mode (already on for the wired node)
   • Roaming Assistant: Enable, set RSSI threshold to -70 dBm
2. Wireless → Professional (for each band)
   • 6 GHz: 160 MHz (or 320 MHz if your country allows and you have 320 MHz clients)
   • Enable 6 GHz Smart Connect band steering
   • Enable Target Wake Time (TWT)
   • TX Power Adjustment: Performance (or Racecar if you’re feeling brave)
3. LAN → IPTV / Switch Port
   • If you used wired backhaul, set the ports used for backhaul to “AiMesh Ethernet Backhaul” priority (optional but clean).
4. Network Map → AiMesh Topology Verify connection types:
   • Second BE98 Pro → 10G Ethernet
   • RT-BE92U → 6 GHz or Ethernet
   • RP-BE58 → 5 GHz or Ethernet

Final Topology Example

Primary GT-BE98 Pro (Router)  
  ├─→ 10G Ethernet → Second GT-BE98 Pro (Node – Ethernet backhaul)  
  ├─→ 6 GHz wireless ──→ RT-BE92U (Node) (Ours - Ethernet backhaul)
  └─→ 5 GHz wireless ──→ RP-BE58 (Node)

Real-World Speeds I’m Getting (Dec 9, 2025)

• iPhone 16 Pro Max on 6 GHz near primary: 2.7–3.1 Gbps
• MacBook Pro M4 Max on 320 MHz 6 GHz near RT-BE92U: 3.4 Gbps
• Wired devices through second BE98 Pro: full 9.5 Gbps (fiber ONT)
• Basement camera → RP-BE58 → primary: 1.8 Gbps on 5 GHz backhaul (BE3600 max shines here)

Tips & Gotchas

• Never mix wired + wireless backhaul on the same node unless you know what you’re doing.
• If you see the second BE98 Pro trying to use wireless backhaul even though it’s wired, force “Ethernet Backhaul” in the node’s individual GUI (log in via its IP).
• The RP-BE58 lacks 6 GHz, so it dedicates 5 GHz to backhaul for optimal client speeds on 2.4 GHz (great for IoT). Use the ASUS Extender app for quick setup if AiMesh search fails.
• Disable “Universal Beamforming” on 2.4 GHz if you have many IoT devices.  It might be disabled by default. 

That’s it! You now have one of the fastest consumer Wi-Fi 7 AiMesh systems money can buy in 2025. Enjoy the overkill. 🚀
