@Joseph-TP btw, my network is this one: isp modem -> wireless router -> devices

@Joseph-TP I have v1.0 of the archer ax53, with firmware version v1.5.4. And here are the screenshots with qos and without qos. The difference is huge. I am on a 300 mbps download and 150 mbps upload...

@Pankajuuuuu I have the same problem, except that i use EU version of the router, still v1 firmware hardware version tho, but yeah
