This seems to be an issue for Asus. It is really surprising that, as but 1 example, most of the RT-AX58U variants are all on different GPL bases if I am looking at this correctly. 5 code bases for 7 routers which use the same basic PCB and chipset. That is a really expensive way to develop and maintain software.I imagine you are still waiting for the GPL code.
