Hi all! New around here. I have just set up my rt-ax86u pro as a router to my modem. I can connect to both 2.4 ghz and 5 ghz on my phone (iphone 11) and on my desktop pc which has wifi 6 supported mobo. Both my phone and the desktop were next to the router when I did the tests. When I speedtest on my phone with 5 ghz, I get the expected speed 700mpbs out of 1000mpbs which is great for me. On the other hand, When I do the same test on my desktop pc, all I can get is 10 mbps download and 0 upload speed which is supposed to be 50 mbps. However, the internet speed on my desktop is all fine while surfing or watching videos on the internet.The results are great when I test the speed on asus router with merlin firmware. I couldn't find any answers for this problem. Can anyone help me with the issue, please? Thanks in advance.
