Since the 1.2.1 upgrade i have had continual wifi disconnection issues on devices all over the house. The hard line connection remains stable even when thr wifi is not.
@jwagman1 When this happens, how did you recover the Wi-Fi connection on the devices? Do you need to restart the BE800? How many wireless devices are affected?

Wifi 7 was great before thr upgrade, now it struggles to get above 700mbps upload when it was st 1600 before. Download speeds remain stable.
Which devices are connecting to the 6G network? Could you please check the link speed on the devices connected to the 6G network after updating to version 1.2.1?

MLO- I don't know why this is even an option on this router. It has never worked correctly and consistently has speeds that are half of what I get on the wifi 7 band even when standing 2ft from the router.
Please try disabling the 2.4G network on the MLO Network and then check again if the speed will be improved.

I sure hope a firmware upgrade to fix these issues is going to be released soon. We are pretty screwed since we cannot downgrade from 1.2.1, which I would go back if I could. This latest firmware did more harm than good. I hope the next firmware doesn't take another 6 months!
I will check with the development to see if they can provide firmware to help downgrade to the previous 1.1.x version for you. Alternatively, you may try the firmware recovery as per this FAQ.

The describe wifi performance are totaly in line with my initial review, wifi is far less performant on 1.21 than it was on 1.1.6. I also tried to switch to access point mode to see if this is related to routing but wif performance are the same between the 2 modes ... Also tried to disable easymesh or not no impact. I'm not using MLO, using split network band performance drop is on both 5ghz and 6Ghz I'm not testing 2.4Ghz bit it is on. I only have wifi lan activated no iot no guest

Hi @Kevin_Z,
I have exactly the same problem as the one described by jwagman1.
I have two BE800s, each firmware version is v1.2.1 and v1.1.6.
Only BE800 with v1.2.1 has disconnection and low throughput issue, there was no issue before upgrade the firmware.
As far as I know, I can't downgrade back v1.1.6, but no longer use with this firmware issue.
Is there really no other way to downgrade the FW version?
Thanks.

I have three links connected, right now sitting 2m next to the BE550, the BE800 ist on floort above me.
Link Speed 229Mbs, BW 20MHz.
MLO Network does not seem to be a really Mesh network as 6G connection and 2.4/5Ghz Smart Wifi has higher
When my Smartphone is next to the BE800 I have 2 Links connected.
The same applies for my computer which has Wifi 7 Qualcomm network adapter (using Linux). Bad MLO Network Link Speed next to BE550 and better but no good MLO Network Link speed next to the BE800.

@Postponed1 If you're experiencing the same issue as described by jwagman1, could you please check my suggestions to him and let me know more details? We will investigate further and help you out.
The 1.2.x is not allowed to be downgraded to the previous 1.1.x version. However, you may try the method 2 in this FAQ.

According to 5Guru's testing results in this thread, I believe the Samsung S25 ultra may only support 2.4GHz + 5GHz or 2.4GHz + 6GHz, it doesn't support 2.4GHz + 5GHz + 6GHz. I would suggest verifying this with Samsung support.

@Kevin_Z I think the S25 is using 3 Band MLO but only connects 2 bands at one time.
What you can see here: The BE550 is only 2m away but the phone is stuck to the BE800 which is far away. Is this a normal behavior of a mesh network?

You may be correct. The S25 Ultra supports tri-band MLO but can only connect to two bands at a time.
From the screenshot, it appears that when you're 2 meters away from the BE550, the 2.4G signal from the MLO network on the BE800 is still strong enough to allow a connection. This isn't related to mesh or roaming, as EasyMesh only functions between the main networks, not the MLO network. Since your phone is connected to the MLO network of the BE800 and the signal is still visible, it won't disconnect to switch to the BE550.
I suggest disabling the 2.4G band for the MLO Network on the BE800 and then checking if the phone connects to the BE550 when you are nearby.
