So, I'm guessing that there might be something in the hardware or software that causes the issue, and the fault lies with the game for creating the issue. I would understand if I experienced the disconnections on the PS3 and the other PC, but I do not. So, there's something about the game that doesn't like something about my PC, but I don't know what it is.
Let's put the shoe on the other foot. I've only ever seen the 90k error once, and that was while I had the game windowed and... posting to the tech forum about something else. The 90K error as far as I'm concerned means the connection has been lost from the server's end. Now as to why this is, I theorize has more to do with occasionally getting a crash instead. The occasional crash went away after updating the network drivers and leaving MSI Afterburner, ASUS GPU Tweak unloaded (these are tools that utilize Rivatuner Statistics Server.) Now the only difference with my setup and a lot of other setups is that I have an Intel Ethernet I217-V network adapter built into the Motherboard as it's not a cheap motherboard. It's also set to Jumbo Packets enabled because I have other GigE devices, and they route through an Apple Time Capsule before going to a SMC Cable Modem.

For the "entire network" to collapse, means UPnP is disabled or broken and the ports are unable to be forwarded resulting in the software filewall on these devices to become overloaded and, crash.

Now I would normally chalk up every single 90k error to this problem, except, again I don't have the problem, I have not set forwarding rules on my ISP's SMC modem, and the Apple Time Capsule is operating as a Switch, not a Router.

So how do you fix it?
1) Buy a high end router, network cards, etc so this problem doesn't exist in the first place
2) Update the firmware, and drivers on your networking devices, if your ISP hands out low-end router/modems this is a lot more likely to be the culprit. ISP's are terrible for updating firmware.
3) Try your same computer at someone else's house.

It's all a matter of eliminating the problem, and it usually goes like this:
1. Reinstall Windows
2. Install stock drivers, try game
3. Install updated drivers, try game
4. Replace suspect hardware, with stock drivers, try game
5. Replace suspect hardware, update drivers, try game
6. Update firmware on networking devices, reset to factory settings
7. Replace networking devices (routers and cables), reset to factory settings
8. Have ISP replace the premises gear, update firmware if possible, reset to factory settings

Having exhausted all of those options, the problem is not within your control.

SE can't fix something that isn't within their control either. I don't see 600,000 reports of connectivity problems, I see dozens. So you're not a majority having problems, but you're still having problems due to reasons that SE probably doesn't have enough feedback about.
