@Pankajuuuuu Not sure if you've read, but I've already done that..

@Harutolist

@Joseph-TP Well, i installed the beta firmware and these are the results- Qos set to 300 mbps down and 150 mbps up(since that's my actual bandwidth from isp), not sure what I'm doing wrong..

@Joseph-TP Will this work if I've upgraded to the latest official firmware that is available on the website for the EU version, v1.5.5?

@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...
