Hello @Joseg235
Thank you for reaching out to us and welcome to the TP-Link community.
As you can find on the product firmware page, the firmware version for Archer AX73 V2 is newer than the one for V1 which added the Bandwidth Control feature already.
Here I will take the global website as an example to show you how to check the firmware version differences. Generally, if the build number of the specific firmware version is newer, it would include the enhancements or bug fixes mentioned in the previous. The firmware version 220121 for V1 has added the Bandwidth Control feature, so the newer 220524 for V2 would also include the enhancements.
