I had this router in early February. Was watching this thread because I was trying to do the exact same thing Paul was. I was trying all these things and couldn't get a solution. Eventually returned it to Best Buy. Still looking for a WiFi 6 solution to this exact problem. Currently using a Netgear Nighthawk r7000 that gets this done right out of the box. Without changing anything. Since this thread went silent I was wondering if the problem was solved and if it was as easy as a update to the routers software. Or if it took a bunch of rules to get it to do what the R7000 does right out of the box.
