I just bought an Asus AX56U because after looking at the supported models for the merlin mod, I was excited to see there is a builtin tool to monitor by IP. Then I saw that this does not work for models newer than AC68. Is this correct? Ive had a couple months that I noticed I almost used all my data allowed by my ISP without penalty. I want to know what device is taking my allotted monthly data. Can I accomplish this on the AX56U with the ASUSWRT merlin mod, or do I need to exchange my router for a different model?
