I upgraded from Fedora 29 to 30. I'm facing a very annoying network issue on Fedora 30: extreme inconsistency on connection speed! My internet connection is relatively fast: I can download files approximately ~10MB/s. One example is Fedora 30 ISO (1.8G) in ~3 minutes. wget https://download.fedoraproject.org/pub/fedora/linux/releases/30/Workstation/x86_64/iso/Fedora-Workstation-Live-x86_64-30-1.2.iso If I run speedtest-cli this is what I get: Retrieving speedtest.net configuration... Testing from COPEL Telecom (138.204.24.191)... Retrieving speedtest.net server list... Selecting best server based on ping... Hosted by COPEL TELECOM (Curitiba) [10.42 km]: 8.223 ms Testing download speed................................................................................ Download: 102.58 Mbit/s Testing upload speed.................................................................................................... Upload: 105.77 Mbit/s Not bad at all. So far so good. However, for the majority of the websites out there, I can not even get 10% of that... that's pretty strange. For the below links I'm getting something around ~100KB/s to ~300KB/s. Yes, extremely slow! Examples: wget http://mirror.nl.leaseweb.net/speedtest/1000mb.bin wget https://github.com/torvalds/linux/archive/master.zip wget https://gitlab.com/inkscape/inkscape/-/archive/master/inkscape-master.zip 1) I tested the very same links links on the other servers I have, and they downloaded even +10MB/s. Super fast. Links are good. 2) The incredible thing is that I live loaded Fedora's 27/28/29 and I could get the super fast result: +10MB/s. Super fast. My network board is working well. By the way, if it was not working well, the Fedora ISO described above would not download at ~10MB/s.

Why few websites Fedora 30 downloads extremely fast and for other websites Fedora 30 is sooooo slow?
Can you please attach a packet capture of a slow download? First few seconds are enough. What is the output of: ip l; ip a; ip r; ip n ?
Uhmm, there are many other people complaining about the very same issue. I'm closing this ticket and any additional report/information should be posted in #1627816. Bug 1627816 - 1Gb/s ethernet port is configured as 10Mb/s port on many different laptops, network-scripts work well https://bugzilla.redhat.com/show_bug.cgi?id=1627816 Thanks for your support Beniamino. *** This bug has been marked as a duplicate of bug 1627816 ***
