Before the Upgrade
(1) Please be sure you have read the Beta Test Agreement before upgrading the pre-release firmware!
(2) For the sake of insurance, it's always recommended to save a copy of the router Backup Config file before upgrading or downgrading.
(3) You may follow the guide to upgrade the firmware of your router. How to Upgrade the Firmware on the TP-Link Wi-Fi Routers.
(4) This pre-release firmware for Archer BE800 V1 can be applied to all versions (EU/US/JP/TW/etc.).
(5) This version of software can be degraded to the previous version.
(6) To use the new 3-band MLO connection, both the router and client device must support Wi-Fi 7 and 3-band MLO. Please note that most Wi-Fi 7 smartphones and network adapters may only support 2.4GHz + 5GHz or 2.4GHz + 6GHz when connecting to the MLO Network.

Thank you very much for the detailed information.
I remember you're connecting a BE550 to the BE800 via EasyMesh Ethernet Backhaul, could you please confirm how many EasyMesh devices are connected to the network (excluding the BE800)? What are they?
Also, are you using the USB sharing feature on the BE800? Is there a USB drive or HDD plugged into its USB port?

There are one main router (BE800) and 3 easymesh satellites in my network via EasyMesh Ethernet Backhaul. The other two are old wifi 6 routers (Arcadyan Boost 2.0). The olde routers work superisely well with BE800. No any disconnection. I will replace them with wifi 6e or 7 extenders later if both BE800 and BE550 settle down well n my network.
No I am not usring or share any USB drive or HDD.

Got it.
Could you remove the two old Wi-Fi 6 routers (Arcadyan Boost 2.0) from the BE800 network and leave only the BE550 to see if the web UI displays properly? I understand this may be inconvenient, but we want to determine if the issue is caused by multiple EasyMesh nodes.
If that is not convenient, that's fine. We've passed your feedback to the relevant team, and they will try to figure it out.
If they need more details, they may contact you via your registered email. Thank you.

I disconnected two old routers. I restarted 4 times. The Web UI was fully loaded every time. It looks the multiple EasyMesh routers cause the issue.
I also found that once I conneected either of the old routers back into the mesh network, all my Iot devices would incorrectly turn into wired clients under the older router in both WEB UI and Tether. In reality, only the main router BE800 boradcasts the IOT ssid, and all the iots are wirelessly connected to the IOT ssid only. Both old routers are set as agent mode in the settings.

@JFDSD Thank you very much for the tests. We will soon investigate this further.

Could you please confirm the sentence in yellow? It seems the old wifi 6 routers are not from TP-Link and I assume they are not manageable by the TP-Link web UI or through the Tether App. Or you're talking about the web UI and Tether app when logging into the BE800?

When I re-connected the old routers back into the mesh network, both Tplink Web UI and Tether (logged into BE800) would incorrectly show my iot devices are Ethernet wired to my old router. All my iots were actually wirelessly connected to BE800 only.

Thank you very much for all the details.
Regarding the web UI display issue with all three satellite EasyMesh nodes connected to the BE800, can the issue be reproduced consistently? Our engineering team would like to investigate further and may need to collaborate with you.
If possible, we'll contact you via your registered email to discuss this further.

Yes. The issue is reproducible. I would say 50% chance of recurrence.
Sure, they can contact me through email.

Hello Kevin. I found a new bug.
On my BE800 device, stop showing my DNS name from TP-LINK, which I provided before.

Also, I can't add any more new dynamic DNS for my USB storage for FTP. (but the old one still works, and I can log in to my FTP by DNS name even if it does not show up lol)

@Kevin_Z - I'm not sure if anyone else is seeing this, but I'm experiencing an oddities where none of my wireless devies are connecting to 5Ghz except for any devices connected to MLO.
