It takes my computer a long time to establish connections with websites

Question

dnf --enablerepo=centos-openstack-wallaby -y upgrade CentOS-8 - Ceph Nautilus 63 B/s | 38 B 00:00 Error: Failed to download metadata for repo 'centos-ceph-nautilus': Cannot prepare internal mirrorlist: No URLs in mirrorlist

This sounds like a nameserver issue. Think about what happens when you request a domain:

1) You request a port at a domain (some website)

2) It checks it DNS cache for the correct address.

3) If not found it queries the DNS server defined in your interfaces. ( I would assume this is your problem here )

4) DNS server repsonds with correct IP and you query the site.

I would bet your DNS server is set to localhost, and its taking a long time to find an authoritative server.

Try setting your DNS server to 8.8.8.8 (Googles DNS) and you should find your answer.

I found that (with Firefox) going to settings - advanced - network, setting it to no proxy did the trick. FAST TO FIND AND LOAD PAGES NOW.

Going to have to do some more trouble shooting on your end to narrow this down. First, I would see if other computers on your network have the same issue. Try to isolate where the problem is and work from there.

Oh right, I forgot to mention that this only occurs on a desktop connected to the router using a Cat6 wire. All of my other devices work fine.

I recently switched ISPs and one of the boxes in our house was behaving poorly. Poked around and discovered that at some point I had set the nameserver address for that box to something other than the ISP's default (which was being flaky off and on). Switched it back to default and things were much better. (Note that you override name servers on a connection basis, meaning that a wired connection may work and a WiFi connection fail, or vice-versa.)

Oddly enough, I switched my DNS server from Google's server to Dyn's server and my connection became a bit faster (I was using Google's before). However, there's still a 2-5 second delay about half the time.

Find your ISPs DNS servers and use those instead. It will be a little better
