[RESOLVED] RE655BE (EU) Stability issues when MLO is active
Update: The latest beta firmware (20250619-rel21989) has finally fixed the issue. An official firmware will be released with the fix. Cheers!
Hello,
I set the RE655BE (EU) up as AP mode.
Configured OFDMA on all bands, and MU-MIMO where possible (5 & 6). These settings can only be set on the web interface, not the app for some reason.
I set everything as Wifi7 WPA3 (or WPA2/WPA3), disabled WPS (though the AP is still signaling the WPS tag on the 2.4 and 5 bands for some reason), put bandwidth for every band to their respective maximum (40, 160, 320), and set the lowest channel on all bands.
I haven't tried EasyMesh, as I have no other EasyMesh devices. The router has wifi completely turned off, so the RE655BE is the only networking device emitting wifi in my home's network.
It's rock solid, and the signal is great even though I have a TON of neighbors and office wifi signals around me (it's a high density mixed-use apartment neighborhood).
Buuut... If I turn on MLO, even though I only have one device using it, stability breaks. It happens more often when my MLO smartphone is far away from the AP. After a while, all wifi goes offline (including non-MLO). OFDMA and MU-MIMO don't change how often it crashes. The AP is still accessible from ethernet, but no wifi available whatsoever.
When wifi was down, I logged into the AP using ethernet, and did a small test: I changed configurations on MLO, and also on different bands (because that triggers a wifi network restart), but it didn't make wifi work again. I have to reboot it to make wifi work again.
So... In summary, if you disable MLO, the RE655BE is a rock solid device.
But MLO is just a no-go for now.
Hoping that you will fix MLO sooner than later.
Cheers!

The link you provided takes me to "Business Product Support", is that correct? So email Support.SMB@tp-link.com? If you want me to send it there I can, but this isn't for business.
That didn't really make sense to me, so I submitted a "Email Support" request through https://www.tp-link.com/us/support/contact-technical-support/#E-mail-Support I tried attaching the device backup, but I'm not sure if it properly attached to the support request as it may only allow pictures such as jpg, png, pdf, etc.
Thanks,
Aaron

Hi@apreslin,
You should select 'Home Product Support'.
However, no worries, if you attach the forum ID and model number along with the issue details, the local support will review the case history here.

No issues with MLO on my 3 x RE655BE in AP mode and with seperate wifi bands configured, however I'm using 3 pin (UK) version running firmware 1.0.7 build 20250205 releasel 32897.

@PindDK Have you tried coming in and out of wifi range with any MLO device?
That's what triggers instability on my RE655BE.

No issues going out of range and then re-entering on any MLO device.
I assume you're now using the latest official 1.0.7 firmware instead of 1.0.4?

Oh dear...I think I might also be experiencing the same. Today none of my clients were connecting to one of my RE655BE units. So I've now turned off MLO and also 6ghz wifi on all 3 units to see if this fixes it.

@PindDK In my case, having MLO on is not the issue, the issue is having clients connected to MLO (but yeah, in your case, by turning off MLO you'll make sure the AP is stable). I'd say that there's no reason to turn off the 6 GHz band.
I do have good news:
I just installed a beta firmware that's just a few hours old, did some tests where all previous versions used to fail almost instantly and... it held on!
So it's a very good sign.
I'll keep you posted in a week or so to confirm if it's still finally stable or not.
Cheers!

Hi@PindDK,
Thank you for reporting your issue to our community.
Is one of your RE655BEs experiencing client disconnection? Are the other two RE655BEs abnormal?
In addition, can you provide your network topology, such as:
ISP modem—router—3-RE655BE )))((( client devices
(Note: — stands for wired connection,)))((( stands for wireless connection )

Thanks, I have updated to the beta firmware, we'll take some time to see if the stability/connectivity issue is resolved.
As far as the secondary issue of WPS staying enabled on 2.4GHz and 5GHz even though it's set to be disabled, right off the bat I can see there is no change with that issue.
