Steam only downloads at around 120Mbps on all of the distros I’ve tried, which are Ubuntu 23.10, Fedora 39, and Manjaro 23.0.4.
The distro sees my 2.5Gb NIC, and the web browser downloads at full speed, but Steam refuses.
I tried everything. Changing servers, installing DNSMASQ, different distros, etc. and nothing fixes it. DNSMASQ did bump up my speed to 300Mbps for a second, but then right back down to 120Mbps.
Upon Googling this, it’s a known issue. A LOT of people have the issue. Some them say DNSMASQ fixes it, others say Valve fixed it years ago, and others, like me, say nothing fixes it, and we move back to Windows where we get 1900Mbps download on Steam.
Everyone who wants to fight me about this, calling me names, all say it’s “an easy fix”, but refuse to tell me until I tell them I am a stupid idiot and apologise for criticizing Linux.
