Looking for the best choice of router I can buy in Canada

Hi, I would like to buy a router which can achieve creating multiple wifi each with different name, mac address, and IP. I tried on the Asus RT-AC3100 and it starts to have problem with 2 wifi on 2.4G network. Not to mention that once I choose random mac address it just disconnect from internet.

I did some research and it is because of the broadcom chip? So I hope some beautiful souls here can help me with a recommendation. I've already brought a Xiaomi Redmi AX6000 which I think can do it, but the shipping takes a month. I want to buy one which can achieve the same thing that I can buy today. Budge is under 1000 usd. Thanks in advanced!
