Youtube Constantly Buffering: Wired and Wireless, Please Help

Question

Hi All,
Hoping someone can shed some light on my issue.  I have a FIOS triple play bundle with 35/35 speeds.  When I run a speed test I typically see 42/38.  The problem starts when I go to watch Youtube videos on any of my 3 consoles.  I have an Xbox, PS3 and a Wii U.  The xbox and the ps3 are both hardwired into the router and the Wii U is wireless.  The problem I run into is that Youtube will constantly buffer almost all the time and render the video unwatchable unless you like a white circle constantly running on your screen.  This happens on all 3 consoles 9 times out of 10.  The strange part is that I log onto my PC, which is hooked wirelessly and I can watch Youtube videos without any sort of trouble.  Both Netflix and HBO GO and other video applications seem to be unaffected on all 3 consoles.  I run into the same problem on my cellphone as well while I have that connected wirelessly where I cannot watch the Youtube videos without constant streaming.  I understand that Verizon doesn't stand behind wireless speeds but the Wii U is not 12 inches below the router and I have trouble on my cell phone within 10 feet and have clear line of sight.  I have called Verizon and they ran me through a speed test and since I was getting higher speeds then what I pay for there is really nothing that they can do.  Any help or suggestions would be wonderful.  Thanks in advance.
I have the MI424WR-GEN3I router and it is running firmware 40.20.1.
Quick Edit: just tried to watch a Youtube video on my PC which usually works the best, and I am not even able to start a video at 360P quality.  I just ran 2 speed tests and receieved 43/29. 
Edit: This can be closed, I just noticed there were 2 posts on the front page about this very same issue.  I give up on watching youtube then I guess.

Some folks have blocked a couple offending youtube cache servers and because it routes them to better ones, or directly to youtube instead and there have been mixed results but I think a majority of people have enjoyed better speeds on youtube because of it.
