Something is wrong in this fair land of ours (and I'm not taliking politics).
My FIOS speed has dramatically declined. I can't figure this out. It apparently is fine for a short burst, but then it just goes to heck in a handbasket.
Here is a representative result from speedtest.net, run on a computer that has been optimized for FIOS and is connected to my FIOS router via Ethernet

The funny thing is that repeatedly, when I run it, the speed test starts out very well, but suddenly, in the download phase, speed just take a nosedive..
See the graph just below the speed dial. in the next image. This is the exact speed test that I posted the results of here as well. 
So, is it time to call Verizon Tech support?
