I have Asus rog Zephyrus gu502gw. I had to fresh install Windows. After that all Asus preinstalled content got removed (not that I wanted them anyway). My internet download speed got very poor, but upload speed is fine. I tried tweaking wifi router settings (changing channels etc) but without any luck. I also updated Intel wireless driver to the lastest version. I 100% know that it's not a hardware issue, I checked the packet loss and etc. How could I fix this? Answers would be much appreciated!
