Internet not accessible if Mini is connected

[rstory]

I'm having a weird issue that just popped up about 2 weeks ago and I can't think of anything I changed that would affect it.

The issue is whenever I connect my Mini to my network, everything works fine and it is able to browse the web as well as all the other devices on connected to my network. AFter about 10 minutes, I can no longer access any web pages on the Mini or any of the other devices. If I don't connect the Mini, my internet stays available continuously.

The weird part is that the other devices still show that they have an internet connection. The Windows 7 machine shows it can access the internet. It seems that I'm still getting notifications on my iPad/iPhone, but no browsing capability. If I do a trace route or ping it is going through as if the internet connection was fine.

Anyone ever run into this before? I've tried creating a new network location and resetting some of the network settings, but nothing has worked yet.

When the issue happened, what are the traceroute/ping results?

Mac mini ping to router?
Mac mini ping to internet address? apple.com or 17.142.160.59
PC ping to router?
PC ping to internet address? apple.com or 17.142.160.59

If the ping results are okay, try entering 17.142.160.59 in the browser address bar and see if it loads the apple website OK.

If yes, you may have an issue with DNS.

Check your router DNS setting, use Google's Public DNS: 8.8.8.8, 8.8.4.4 and see if it works better.

If yes, your ISP needs to fix their DNS servers.

Do you have an online backup on the Mini or something else running that could consume tons of bandwidth? Torrents, etc.?

I thought it was a bandwidth issue, but I turned everything off and it still occurred.

It does appear to be a DNS issue. I changed to the servers given below and I've been running fine for an hour now. We'll see what happens.
