FiOS Internet

[#1]

Hi, I am hoping someone might have experience with this, just installed dlink powerline adapters, they are connecting, I am able to get emails, all lights are green on both adapters, web pages load fine speed is amazingly fast.   I have quantum fios I think 75/35

The problem I am having is the computer loses connection when for example I go to a site like speedtest.net or even downloading podcasts, after a few seconds the network icon on in the task bar goes to a triangle with exclamation point and I lose the internet. It starts to download but then it stops. It also seems like it disconnects when I turn on a wireless device like an ipod.  I know the powerline is not wireless but does the connection somehow get bumped when another device accesses the internet? It happens no matter what computer is plugged in to the adapter, even when I move the adapter to another room on a laptop. 

I have to keep disabling the network adapter and re-enabling the network adapter to get it to work.  It loses connection to the router also, I don't get to 192.168.1.1

 I updated the network adapter, turned the router on and off, rebooted and ran some command prompts to flush dns still no joy.  It will work fine all day if I am just searching the web or getting emails but when it requires a longer time access on a website it goes down. 

Any suggestions on how to fix this?

Thanks in advance

What model of Dlink adapters, or adapter package?

It may be that the buffers in the adapters, just will not handle continuous FiOS speeds.

If you just purchased them, you may want to try a different vendor or or newer model?

This could be caused by having too many devices connected to the same circuit that either end of the power line converters are connected. Are both ends of the power line converter connected directly to the wall? They should not be connected via a power strip and too many power strips on the same circuit is a problem (in some cases one could be too many).
