H! I am getting a problem that I use internet through modem. Previously I used it on Windows and it was giving a handsome 500kbps speed. Now I uninstalled the Windows and got Fedora 27. But It is not giving such a speed. It is very slow speed giving of 50kbps-. I checked everything in network setting from Network Icon on windows bar, top of the screen as well as I configured the network through PTCL IP. But all is vain... Please help me troubleshooting this and getting back to my smart download speed.

One of the problems is that gnome software automatically starts downloading updates at startup. This slows my computer and the internet speed for a time after startup.

You could disable it:

Just issue in terminal "sudo dnf update" whenever you want to bring Fedora up to date.

Welcome to ask.fedora! This may or may not be a fedora issue, so let's do a bit of testing to find out. First, open a terminal and run this command:

ping -c 10

When it's done, check to see if there was any packet loss, and what the average time was. Next,

ping -c 10

and again, check the statistics. This will give you two sets of data from locations on opposite sides of North America, and probably across different parts of the backbone. For me, in Southern California, the average time for was 38.696ms, just to give you an idea. Unreasonably long times, or significant packet loss indicates a network issue, that you need to take up with your ISP. If all seems well, we can look further at your computer's config and see what needs tweaking.

You could disable ipv6 in "Wired connected>wired settings", if you still have problems , directly in firefox you could disable ipv6.

  • In the search bar type : about:config
  • search: network.dns.disableIPv6 and change the value to True

I do not know how disable that in chrome, sorry
If you have problems about failed sync when you install programs or update the system by the terminal, or it is very slow in the beginning , you could use the -4 option always to force ipv4, for example:

sudo dnf update -4
sudo dnf install screenfetch -4
