Archer BE550 Pro - Random Reboots / Instability Due to MLO
I wanted to make this post here to help anyone else out with the BE550 Pro router. YMMV, of course, but this worked for me.
TLDR; If experiencing random reboots/instability with this router, disable MLO. It's been completely stable for me ever since.
I was frustrated with this router frequently dropping internet, causing all my SSIDs to drop for several minutes at a time. I had to either wait for it to recover on its own, or forcibly reboot the router to get it to recover.
This was completely unacceptable, especially while working from home. After many hours of troubleshooting, I discovered that MLO was the culprit of the problem.
My current theory is that the MLO software on this router is still buggy, as this variant of router hasn’t received a firmware update since December 2024.
PS. Not to mention, MLO is essentially without any real benefits right now for everyday client devices.

Hello @linkuser8282 ,
Welcome to our community.
Are the MLO SSID and the main network SSID the same? Is only the wireless device disconnecting? Which client devices are involved?
Please go to the firmware update page to check for new firmware.
We recommend sending an email to forumsupport.usa@tp-link.com with the following information:

No, separate SSID for MLO, the main network, and an IoT network
All SSIDs would crash (disconnected all devices, no SSID broadcast visible) along with Ethernet connectivity until the router either recovered on its own or I would manually reboot it.
Client devices involved were an extremely typical mixture of WiFi 4-7 devices.
WiFi 7 devices were connected to the MLO SSID only and consisted of a few iPhone 16/17 Pros
along with a FastConnect 7800 PCIe WiFi card.
I am running version 1.1.1 of firmware, which is the latest for this device/HW version (December 2024 last firmware update in US).
This post was meant to be a PSA for anyone else with this router that may happen to experience the same issues as me. The router is working just dandy now with MLO disabled and I’m happy with that. I do not wish to hand over my logs at this time for review, especially as the router is stable now and any potential gains to be had with MLO in a router to client real world scenario are negligible.

@linkuser8282 I'm running this newer version and build, and my WiFi just dropped today... poof. This router is just a month old. After trying a reboot twice, I finally had to factory reset and set up the whole thing again. Should I send this back or just shut off the MLO? This is a newer version and it's still an issue indicating it's not likely to ever be fixed. I thought the MLO would be handy when I go out to the yard and my 5G fades, thought the phone could then pick up the 2.4 seamlessly. I've never had a router just stop broadcasting like this before and all the networks disappear.

Today I was connected to the MLO WiFi network and all of a sudden all of the WiFi signals disappeared. Tried rebooting but none of the WiFi networks would show up. I had to do a factory reset and completely set up the router again.

That’s ultimately your decision to return or not. I thought no MLO would be a deal breaker for me, but personally, even with MLO enabled (and when the router cooperated) I found basically zero real world benefit for my client devices.
For your usecase described below, I suggest to disable MLO and set the primary SSID 2.4/5g/6g network name the same so your phone will automatically switch.
Then put your slower devices, IoT devices, etc. on the respective IoT/Guest Networks as necessary.
At the end of the day, I figured why go through the hassle of exchanging/returning a router because of one feature, which in real world testing provided no noticeable benefit..
I’d be curious if disabling MLO also fixes your issue. If you try this, would you kindly report back your findings?
