if disabling the wifi somehow gets the connection to work, IP connectivity shouldn't have anything to do with it and it shouldn't have anything to do with DNS/IPs/Gateways/port forwarding/etc... and the fact that some of the hashrate gets registered using ethernet, it means the ip connectivity exists enough to transmit information to the pool, which means the ports/gateways/etc all should be fine.
This is pretty much my assumption as well.
If it is a verizon router, you should have access to the cts setting (or you should, I know I see it on mine...) after going to 'wireless settings' at the top, go to 'advanced security settings' on the left, and then at the bottom click 'other advanced wireless options'
This gets you access to the transmit power/cts setting/etc... but its possible you have an older firmware or an older UI on your router... teamviewer might be best to troubleshoot this. (in which case, try updating the firmware under the 'advanced' menu)
Although, again, I would think getting the same exact model router as the other guy would fix the situation (if the issues are identical)
EDIT: There is also a 'Wireless QOS' area that you could mess with as well... not sure if you modified the main QOS settings, or the wireless QOS settings, but on my verizon router they are separate. (*The Wireless QOS settings are off of the same page with the CTS setting - at the bottom under the "WMM settings" link)
EDIT #2: (now that I have access to my verizon router - screenshot

EDIT #3: modified due to my misunderstanding of the initial setup
I appreciate the screenshot, I'm not sure how but I missed the 'other advanced wireless options' link at the bottom of that page until now. Seems like a strange place to put it based on how the rest of the UI is laid out. Unfortunately CTS (both cts-only and rts-cts) mode didn't make a difference. I tried lowering the RTS threshold in conjunction with this also without success.
I previously modified the main QOS page, which had a section for wireless. I don't see a wirless QOS section on the page with the CTS settings. I promise I looked thoroughly this time
As I read it his blades are all wired to a switch which is wired to the router. The wireless is just for his non-mining wireless devices, right? What does it say on your router info page that lists all attached devices and their ip addresses?
This is correct. I have a few roommates who's PCs connect wirelessly, as well as cell phones, tablets, etc.
Also, try upgrading firmware on router.
Firmware is up to date.

Haha, thanks for the laugh.
I ordered the other router, and had it shipped overnight so it'll be here today, the 24th, and hopefully that works around the issue and gets the blades up and running. Thanks for all the suggestions and input so far.
