Problem:
I've been having packet loss for the past week. This appears to be large packets sent in any consistent pattern.
For example:
Running something like:
ping -l 8192 -t usatoday.com
Would return a time out every few lines. I'm also seeing games flash warnings of packet loss.
My steps taken so far:
Replaced the ISP supplied modem with a purchased private modem.
Had the ISP technician replace all wire ends and check for ingress
Swapped to a different separate wireless adapter
Swapped to another previously working operating system
Updated the drivers for my wireless adapter
Ran the above batch statement on a different computer to replicate the same results
The only remaining option I can think of now is that the cabling within my walls has deteriorated. I've attached my network information in the text file.
Can anyone perhaps point me into the right direction here? Any additional obvious troubleshooting steps I've perhaps missed?

I suggest that you disable that setting in your Realtek adapter configuration properties settings. If that doesn't work, you'll have to also login in directly to your Wi-Fi router as an Admin user through your directly connected computer, such as a laptop. You can also use the computer in question to change that setting in your router; save that setting and reboot your router. When you are logged into the Admin utility of the router, it's also good practice to make a backup of your router's config (.cfg) file to your computer desktop or external media such as a flash drive or a Cloud account such as OneDrive or Dropbox. 
Not guaranteed of course, but as it appears you are using a laptop, some wireless adapter drivers have had issue with the simultaneous use of both IPv4 and IPv6 addressing schemes as mentioned. This has been well documented on the Internet going back to 2009 when Win7 computers (and W8.x computers) first came out. It's often seen in laptops with built-in wireless adapters as well as G and N routers. I've only seen it a few times on AC routers.
The moral of this story is, that people try to save money by cutting corners and buying their own Network equipment when the ISPs have thousands of man-hours spent analyzing the intricacies of all the Modems available on the market to make them work with their networks. So, when a home user tries to circumvent that, and save a few dollars, they often fail because they think that a Modem is a Modem is a Modem, right? 
At that point, replace the router with a brand new one. That would then fix the problem there. 
but the current paradigm of the ICANN is certainly not going to change anytime soon. I think that he needs to try some more of the suggestions I gave him in my post above, such as taking his computer to a friend's or neighbor's house or even to a public site such as a Starbucks or an Internet Cafe and run his test. Nothing he's provided us has shown packet loss, but you mentioned MTU size; if he has changed the default MTU size in his Router, that could be causing fragmented or misformed packets.
