"The bug that Tether changes to router device names do not take effect" on A7 is also on A9
You recently released a new firmware (version 1.1.2) for Archer A7s to that, in the release notes, "Fixed the bug that the Tether changes to router device names did not take effect" - I wanted to publicly announce this same bug effect ALL A9's I've ever purchased, and the fix needs to be applied to this firmware as well.
