Hi,
We’re not entirely sure how their testing was conducted.
After an initial discussion with our R&D team, we can confirm that the BE9300 and BE3600 (as well as other upcoming Wi-Fi 7 products) support STR-MLMR, meaning they can transmit data simultaneously across multiple bands.
When connecting a supported device to the router, the driver information indicates this:
(My phone only supports Wi-Fi 7 on 2.4GHz and 5GHz, so it only shows two bands.)
You can also perform a simple speed test using a device that supports MLO + STR-MLMR. You should see that the wlan02 (2.4GHz), wlan12 (5GHz), and wlan22 (6GHz) interfaces are transmitting data simultaneously.
Please make sure the phone has successfully negotiated and decided to transmit data across all bands; otherwise, you will only see traffic increasing on some of the interfaces.
(The number of RX/Tx packets and bytes will increase.)
ifconfig wlan02 && ifconfig wlan12 && ifconfig wlan22
