Question Network issues - cannot connect to network

I'm running fedora 20 on two boxes in my house. They are hardlined to my netgear 5 port unmanaged switch that is connected to my UVerse router/wifi/modem. I can pull an IP on both systems and ping even while the symptoms are presenting themselves. Both systems use Chrome.

What happens is that when a webpage is trying to be loaded, (most times this happens reliably is right after boot) The page either says that it can't be loaded or images on the page dont load _or_ it spins for a looong time before being able to load it. (looong == minutes).

Nothing that I can see is logged in messages. And to the best of my knowledge the window's installations on these machines don't have this issue (though they have many more and I am working on testing this for sure now.)

What do?!? I'm not good with networking lol. SO this is about as far as I can take this one myself. Are there any known issues that i'm unaware of?

Thanks all

Are the F20 boxes VMs running underneath windows? If this is the case is it something to do with the network settings on the VMs?

Nah. They're just dual booting. Nothing fancy like VMs

Re: Network issues - cannot connect to network

Check your DNS. If the DNS is lame then this will happen.
# cat /etc/resolv.conf
# dig @dnsipaddress www.google.com

DNS! Why didn't I think of that?! Thanks I'll check when I get home. I forgot to leave the system on so ssh won't be a thing... Incidentally, I thought in fed 20 we didn't use resolve.conf anymore for some reason. Stupid me. lol

tl;dr - will check when I get home

Re: Network issues - cannot connect to network

Here's what I've got. Ran this while the issue was happening. In fact facebook is still spinning to load...

I used Google's famous 1.1.1.1 DNs for the dig test.

Re: Network issues - cannot connect to network

I had a similar problem. The problem lies with your IPv6 configuration. Try going to about:config of your firefox browser and set network.dns.disableIPV6 to true. Restart your browser and facebook should open fine.

Edit -
If this doesn't work for you then please post results of ifconfig of both the machines. I want to know the mtu value set there.
