Important: After installing this firmware, we strongly recommend performing a factory-default reset to activate every new security adjustment.

Security Enhancements
- Password Policy Upgrade – Minimum 10 characters with at least 1 letter, 1 digit and 1 special symbol, and no consecutive identical characters; hardens defence against brute-force attacks.
- HTTPS on 8443 – Management interface now served over TLS by default.
- UPnP Disabled – Universal Plug and Play starts in the off state for reduced surface exposure.
- AiCloud Authentication Hardening (CWE-287) – Added layered verification.
- Authentication Logic Refactor – Removed redundant code paths for a lean sign-in flow.
- Memory Safety Guard (CWE-476) – Introduced null-reference protections across critical services.
- Enhanced IPsec Parameter Validation – The existing input checks have been hardened.
- Data Exposure Mitigation (CWE-200) – Reinforced controls on sensitive pathways.
- Detailed Audit Trails – Expanded logging within the authentication module.

System Improvements
- System Stability – Reduce reboot occurrences.
- Connection Stability – Core algorithms refined for steadier links.
- Scheduling Accuracy – Timed tasks execute reliably under PPPoE, PPTP and L2TP WAN modes.
- Client List Maintenance – Resolved an issue that prevented offline devices from being removed from the client list

Interesting about the factory reset after update... I assume one can hit the Administration menu, then save a copy of the settings, then restore that once setting up the new router, otherwise this would be a PITA update and then have to reconfigure the router from scratch. I did some AI chats about this if you all are interested, and they recommend the long approach, Ugh... I guess one could try it with a settings restore and then see if you get anything strange, but for me, I usually like the cleanest method for no chance of issues cropping up. Guess I'll take some router screenshots of the menu. If you get the SSIDs, PWs and security settings for the networks the same, all your devices should reconnect without rejoining them. Worth noting that Asus changed the default port the router mgmt page uses to 8443, so you may need to specify :8443 after the URL, change your bookmarks and remove the old auto fill URL from the browser.

That’s a very recent firmware drop (Aug 15, 2025), and it’s an important one for your exact concern about MLO stability. Let’s break it down:

Security Enhancements​

ASUS is clearly hardening the management side — stronger password policy, TLS-only management on port 8443, UPnP default-off, memory safety guards, etc. All good moves for long-term stability/security.

System Improvements (the part that matters for Wi-Fi/MLO)​

• System Stability – Reduce reboot occurrences.
  Early adopters of ASUS Wi-Fi 7 models (BE92U, BE98, etc.) have reported occasional spontaneous reboots. This line suggests ASUS has patched some of that.
• Connection Stability – Core algorithms refined for steadier links.
  This is almost certainly aimed at Wi-Fi 7 and MLO — forum chatter and Reddit posts (as I shared earlier) show people having connection drops, latency spikes, or client disconnects when MLO is on. ASUS seems to be refining the “core algorithms” for link management, which could mean better MLO handshaking and fewer random disconnects.
• Scheduling Accuracy / Client List Maintenance fixes are smaller QoL tweaks, but they also point to ASUS cleaning up router logic that sometimes mis-handled clients (e.g., ghost devices, or failure to refresh MLO/roaming states).

Key Takeaways for You​

• This firmware directly addresses stability, which has been the #1 complaint with MLO in early Wi-Fi 7 firmware.
• A factory reset after flashing is strongly recommended (ASUS is explicit here) — that’s often critical because Wi-Fi 7 and MLO configs may not fully apply on top of older settings.
• If you want to test MLO again after upgrading to Windows 11 24H2, this is the firmware to do it on — it should give you the best shot at a stable experience.

---

If you’d like, I can walk you through a “clean upgrade path” (backup → firmware flash → factory reset → MLO config) so you can maximize stability with your BE200 once you go 24H2. Want me to lay that out step by step?

You said:​

Can I backup my Asus config, upgrade FW, factory reset router, then restore my settings and be right back up and running without having to configure anything?

ChatGPT said:​

Good question — and this is where ASUS gear is a little tricky.

What you​

• You can back up your RT-BE92U configuration (Administration → Restore/Save/Upload Setting → Save setting).
• After flashing the new firmware, you can factory reset, then restore that config file.
• That will technically put your SSIDs, passwords, port forwards, DHCP reservations, etc. back into place without re-entering them manually.

The catch​

ASUS themselves (and many power users on SNBForums/Reddit) warn that restoring an old config after a major firmware base change can reintroduce old bugs or prevent new features (like improved MLO handling) from applying correctly.

• Wi-Fi 7 stacks are still maturing — sometimes the config backup contains legacy flags that don’t map cleanly to the updated firmware.
• That’s why the note in the changelog specifically says “we strongly recommend performing a factory-default reset to activate every new security adjustment.”

Best-practice upgrade path​

Here’s what I’d suggest for your situation (BE200 + Win11 24H2 + MLO testing):

1. Backup your config now (so you don’t lose your SSID/DHCP reservations, etc.).
2. Upgrade firmware to 3.0.0.6.102_38961.
3. Factory reset (hold reset or via GUI).
4. Manually reconfigure key settings(SSID, WPA3, DHCP reservations, MLO toggle, WAN info).
   • This ensures new security/stability code paths are activated cleanly.
   • Painful, but safest.
5. Optional shortcut: if you restore your backup and things seem weird (unstable MLO, ghost clients, odd reboots), wipe again and re-enter by hand. Many users on forums report this solves “mystery bugs.”

---

So: yes, you can restore and be up quickly, but for maximum stability (especially with Wi-Fi 7 + MLO), manual re-entry after reset is strongly recommended.

Do you want me to put together a minimal “settings checklist” (just the must-enter-again stuff) so re-config only takes ~10 minutes instead of redoing every obscure option?

@NismoZ I guess it depends on how complex your settings are. Mine are mostly trivial. If I had a very long way to manually reconfigure, I'd 100% try backup and restore. Worst comes to worse hard reset and manually do it.

There are two pages that pop up in the beginning, one asks if you are older than 16 yo, the other some sort of privacy disclaimer. (I honestly did not read them). I wonder how it affects functionality IF you just flash the update and because of not hard resetting you are not agreeing to those terms...

 

[jzchen]

Sorry I do not have the patience to read through 21 pages of posts!

I had all 4 external antennae straight up like the pictures, only to read through the manual to find that the optimal is to have the two outer antenna at 45 degrees. Does everyone else have them at the "correct angles"?

 

[alba666]

All 4 of mine are vertical.
I tried different positions and it didn’t seem to make any difference.

Ok, I'm up and running on the new firmware. I took the path of screenshotting my menu settings screens in a word document that I could reference upon router reconfiguring after the router FW flash and then factory reset. Went smooth, and pretty quickly; all clients reconnected fine. I have one laptop on 6Ghz that I plan to test later when I update to Win11 24H2 which enables WiFi7 320Mhz channel width on the OS to see what the negotiation link rate might be. Right now, I'm 1.4-1.7Gbps on the negotiated link rate and 1 floor away from the client, which isn't bad for 6Ghz with no MLO. I don't intend to enable MLO and introduce multi band organization yet, I just don't have much that would benefit since the 6Ghz 320Mhz channel width by itself is way faster than I need and I don't have anything struggling at the edge of the network that would benefit from having 2 bands on 5 and 6Ghz that a client can make use of. However, I am looking forward to seeing some folks who can make use of it, telling us if Asus improved the stability and performance of MLO, like they mentioned in the FW notes.

Couple pieces of info for some folks on the upgrade procedure. There was a strange thing on setup, when you move through the first few welcome screen questions and initial config, right after you add your WiFi SSIDs and hit submit, it hangs there for a while and you cannot refresh, so you think that it's stuck. If you wait a while, the router was rebooting during that time and will come back up. Also, word to the wise, UPnP is disabled now from factory for some security reasons. Since there are multiple threads out on Google covering this subject, I'm not going to get into a large discussion on that topic here since it would derail the thread. However, if you don't want to have to set a static IP on a few of your devices like game systems and some other things that need to open ports on demand to fully function, and then create port forwards to those static IPs/MACs, then you need to reenable UPnP once you research the topic and accept what security risk there is. UPnP is one of those things that's made a home network very user-friendly over decades and to turn that off may surprise some folks if their specific UPnP devices do not work correctly.

Environment dependent. There is no universal optimal position.

No, that doesn't change anything, you are copying the old settings then recopying them back. The whole point of this factory reset is to start out new with the new feature set.

 

[jzchen]

FWIW I actually don't ever remember UPnP being defaulted ON, OR to be honest maybe AiProtection is the one advising to turn it OFF which I'm confident it does.

I've just finished updating to the latest firmware (ending in 38961) and I have some notes about it too:
- You now have the option to block internet access for wireless devices. In the past 2 releases, you could only block it for wired devices. I've now happily blocked some "smart" light bulbs from accessing the internet.
- There is a new tab labelled "Game" and gives you access to the "GearUp Console Booster". I don't have a need for it, so have left it off.
- There are now less options under the Wireless: Professional settings to adjust.

Under Firewall, I still can't get the URL Filter to work. There are a couple of sites that I'd like to block, but in the 3 firmware releases that I have had this router, the feature hasn't worked.
Anyone been able to get this working?
I've done all the obvious things and it worked on my recently retired RT-AC68U. (Obvious = Feature is Enabled and the entries are in the Deny List ).
I haven't yet enabled the Parental Filter, since I started using this device. I'm waiting for it to stabilise a bit before I switch some of the extra features on. (Note about stability, although I have a customised/non-standard configuration, I've been lucky and it has run stable without any issues or restarts for the past 2 firmware releases. First one was for just over 30d and the last one was about 45d.)

Thanks,
GJ
