The previous thread this is closed but I still have a network problem.
Today, suddenly the network on Manjaro slowed down. I have 3 machines: 1 Desktop, 2 Laptops. All of these machines have same problems. So I guess it is not a driver issue.
When I connect to a cellular hotspot, it works fine. But It might be not a router issue. The same network under the router, Other OS are working fine: iOS, macOS, Windows 10.
Windows 10 is even same machine on the desktop.
I thought it is Manjaro issue because all of the machine that has problem are installed Manjaro. So I removed Manjaro and installed Arch Linux, but there is same problem. Live boot mode was fine, but installed Arch has same problem.
I already tried both NetworkManager and dhcpcd but not helped.
Sorry for my poor and ugly English. But anyone can help?
