HELP: Unstable Connection

[boultonclr]

We have been unable to have trust worthy internet connection for the past two months.  I was wondering if anyone has had the same issue.  To began it started out with a connection problem that I couldn't fix through the normal means.  After calling Verizon they sent us a new modem, a d-link 2750b.  We have been still facing the issue where our internet light on the modem will go off and will not come back until turning the modem off and back on, mean while we have no connection (without losing sync).  Now this isn't a problem that much but when it can happen like 10 times in an hour its quite annoying.  I have called back many times to get it fixed but with no luck.  The computers used one runs on vista and the other is on windows 8, both wirelessly, running with a Ethernet hasn't made a difference either.  If I run the diagnostics tools on the modem page the vista fails the ping test with 100% loss and the windows 8 fails the ARP test even if we are connected at that exact moment to the internet.  There are filters where there needs to be and none when there shouldn't, the configuration of the modem is also good, and according to the many tech's that have come the numbers all look good.

Now if I run the internet dianostic tool while I have connection it might show up all good or it may be bouncing back and forth between these two error messages causing the connection to be slow:

This also tells me the problem is not fixed because soon enough when the internet light goes out I get the following message from the tool:
