I just upgraded from 25 Mbps to 75/75 and found that my downloads started failing reliably. I also notice that when I stream video content (e.g. NASATV) it hangs MUCH more regularly after only a few seconds.
When I use the various speed test tools, It often tells me I have ~75 Mbps up and down, but often times it times out as well.
As if the speed is there for a moment, then something drops out.
Have others experienced that upgrading FIOS has reduced quality?
NOTE: I have an updated wireless router. I have seen this on the wireless and wired connections.
