Model: Archer BE800
Hardware Version: V1
Firmware Version: 1.2.3 Build 20250314 rel.45415(4155)
Just bought the BE800. On initial setup, Wi-Fi 6 was available. Connected to this. It automatically updated to the latest firmware and then I noticed the WiFi 6 connection disappeared (contrary to the patch notes).
Rolled back to
| Archer BE800(US)_V1.6_1.2.1 Build 20250108 |

as I saw someone else had a similar issue. Things worked fine.
When I try updating to 1.2.3 again, Wifi 6 disappears, speeds drop. Interestingly, MLO still connects to 5ghz and 6ghz but speeds are 200mbps slower.
As per previous suggestions:
Please test the speed at the same node and the same location for comparison:
1. Fixed 5G channel to 36, channel width to 80Mhz, and test the speed of 5Ghz alone;
2. Fixed 6G channel to 69 (PSC), Mode to 802.11BE, channel width is 320Mhz,and test the speed of 6Ghz alone.
DId this, no change.
1. Did you test the specific speed when the problem occurred?
Yes, MLO dropped from 950 to 700, 5ghz dropped from 900 to around 600
2. What clients did you test the speed?
Desktop PC with MSI Herald-Be Wifi device, S25 Ultra
3. Which specific bands have the speed reduction problem?
6ghz disappeared, MLO still showed 5+6ghz but speed dropped from 950 to 700 max
QoS was turned off.
Tried another firmware update to the latest version. No bueno, speeds dropped and wifi 6 disappeared.
Thanks!
