Work in Progress! I will add more content as soon as I get around to doing more tests. It isn't easy to do as I have a full-time job.
MLO or Multi-Link Operation is a technology introduced with WiFi 7 that allows a Multi-Link Device (MLD) to connect to 2 or more frequency bands simultaneously. A MLD can be your Laptop, Phone, Tablet or even a Mesh-Network Node.
Please also read this amazing Paper from Intel about WiFi 6E and WiFi 7 (Including MLO): Intel - PDF - wi-fi-tutorial-long.pdf
There are multiple different ways a MLO-Connection can be established with. The best one is E-MLMR (Enhanced MultiLinkMultiRadio) which is, at the time of writing this (September 2025), not supported by many STAs yet.
In this Section, I will note down my detailed knowledge and insight I have gained into MLO with my experimentation.

To learn more about the Capabilities of a connected Client or of the AP itself, you can open an SSH-Connection to the AP and use Linux-Commands. I have compiled a short list of commands to see certain Information thats important for my use-case:
wlanconfig <interface> list - shows all connected Stations connected to the PHY and lists a lot of information about the connection such as TX/RX Rate, Power-Save state, SNR, TX-PWR of STA, PHY-Mode and much more.iwconfig - lists all PHYs, their TX-PWR, SSID & MAC, Frequency and some more./bin/fanctrl_wrapper.sh - Lists the Temperature and if the Fan is running. I never heard the fan spin up except on boot. Even though the AP is hovering around 86°C which is very toasty for an AP.
