I'm having some networking problems that I can't figure out. I had Ubuntu 16.04 with these problems and just upgraded to Ubuntu 18.04 and they are persisting. The upgrade kept hanging (installing from Ubuntu Live ISO image on both USB and DVD). In the end I did the minimal install to finally get through. Unfortunately, after upgrading i found that my networking problems persisted.
I have multiple devices connected to my router. They are all working fine before and after a reboot. But, my Ubuntu machine continues to have problems.
Here is a summary of symptoms that I'm seeing.
I can browse the internet just fine. I'm writing this post from Firefox on the machine in question. I've loaded a large number of pages just fine.
sudo apt-get update
also works fine.sudo apt-get install vim -y

Eventually (after a long time... 5 minutes?) I'll getIgn:1 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 vim-runtime all 2:8.0.1453-1ubuntu1
and more of these if I wait long enough. What's odd is I can use firefox to connect to

just fine.Opening Software & Updates and using the automatic Select Best Server option eventually fails saying

My ISP is comcast. I ran this speedtest. I get great download speed results but the upload speed test completely fails and doesn't even give a result stating the test failed.
As I mentioned, I was seeing similar problems like this before the upgrade from 16.04 to 18.04. I did not keep as detailed of notes from before the upgrade... I had been wanting to upgrade for a while and naively hoped that a clean install would automagically fix things...
This machine is connected through a 100Mb/s hard wired connection. Wireless is completely off.
I'm stumped...

It's been stuck now for over 5 minutes...wget
? I'm trying to determine whether this is a general network problem, a problem only existing outside firefox or a problem accessing this specific host or network.
