I did have to start the counter over again due to requirement to boot into other operating system yesterday. Have had no issues in the last week with DNS resolution (the problem I was having prior to NIC upgrade).
Going to try to go two weeks without restarting, for any reason.

john@debian:~$ uptime
18:47:28 up 1 day, 4:13, 2 users, load average: 0.28, 0.14, 0.09

So, in conclusion, and to sum up as briefly as possible, in my opinion, it was the network interface that was causing the DNS resolution problem. And it was fixed with Trieudoahong's suggestion to upgrade the NIC. I haven't had any DNS resolution problems in over 12 days, and I think it is safe to say that this problem has been solved by upgrading to an Intel NIC expansion card.
So much for my conclusion, as foregone as it were.
Consider this: so, some time ago I hastily concluded that my problem was solved by virtue of a NIC upgrade. It turns out, that even though I upgraded my NIC, which at that time seemed to be the resolution of my DNS lookup issues, that the NIC upgrade was only a step in the right direction. Without getting bogged down in too many details, I migrated over from using the Chrome browser(due to Flash format issues), to using the Chromium browser. From the time I upgraded my NIC until the time I stopped using Chrome and started using Chromium, my DNS issues had disappeared. However, when I started using Chromium browser, my DNS lookup issues returned. The good news, and showing that persistence pays, is that I finally found a clean and quick, uncluttered, instruction to use non-default DNS servers at:
Note, this is for Debian Linux, and after all the time, treasure, and effort I have put into this, one thing I have learned is that Debian Linux is slightly particular about this, but the above linked is tailored just for Debian Linux!
I am returning this thread to "Unsolved" status, and will be resuming my previous practice to running the "uptime" program every so often to let you know how progress is moving along.
As a baseline, I will post the current uptime below.

I have had to reboot once here lately. But, as of today, and projecting current computer use, I do not foresee a reboot for at least a little while. Current uptime states are as follows:
Code:
john@debian:~$ date
Sun Sep 28 17:11:33 MDT 2014
john@debian:~$ uptime
17:11:35 up 7 days, 21:45, 2 users, load average: 0.35, 0.65, 0.57

I think I am going to try maintaining an system up status continuously for a couple of more weeks, with status posted here. And then if it goes as planned (no breaks in status continuously up), I will probably close the thread as solved. The latest statistic is posted here.
Code:
john@debian:~$ date
Sat Oct 4 15:00:41 MDT 2014
john@debian:~$ uptime
15:00:42 up 13 days, 19:34, 2 users, load average: 0.19, 0.09, 0.12

By the way, I am not using Google Chrome nor Chromium currently, due to unresolvable issues regarding Flash. Using Iceweasel, Debian's brand of Firefox. I have no clue as to whether it has anything to do with my success thus far, but I thought I should mention it.

Reason: Addendum
I think, for the purpose of thoroughness in testing the current network situation/behavior, I am going to keep this uptime thing going for a little more than one more month. After that, I am thinking I should probably go ahead and boot Windoze to run the updater in that environment. At any rate, here are the current stats:
Code:
john@debian:~$ date
Sat Oct 18 16:32:47 MDT 2014
john@debian:~$ uptime
16:32:49 up 27 days, 21:06, 2 users, load average: 1.07, 1.01, 1.00

I had to reboot due to a computer program failure.
I have probably done enough for this thread though, so I am going to hopefully post the uptime stats for the last time for this thread, and mark it as "Solved".
Code:
john@debian:~$ date
Sun Oct 19 14:28:54 MDT 2014
john@debian:~$ uptime
14:28:56 up 1:55, 2 users, load average: 0.05, 0.14, 0.18

If I get a recurrence of the original problem, I will open the thread back up and resume contributing to it.
