So after all the time spent trying to resolve this Netflix connectivity issue with my Sony BX59, and spending hours with Sony, Netflix, ActionTec and Verizon support whom, by the way all fingerpoint to each other as being "their fault", I finally resorted to searching for different Mfg of BluRay players exhibiting similar issues. Lo and behold I found a number of Samsung BluRay players having similar issues however it wasn't until I found Xbox users complaining as well.
Briefly, this connectivity to Netflix issue began in Mid-November. Up until then, I had no problems. According to ActionTec, Version 40.21.10.2 firmware was released at the end of October. I don't exactly know when my Router was updated but I assume it was around November.
To resolve the connectivity issue, I had to change the MTU settings (Broadband connection). The factory default was set on "Automatic" and 1500. When I changed the setting to "Manual" and reduced the number to 1492, Netflix was able to connect. I changed the setting several times to verify repeatablilty of success/failure. I was able to arrive at 1492 by starting at 1499 and incrementally reduced the number by one until I could get repeatable results. The question remains however is "why"? Is there something in the new Firmware? I don't know much about the advance settings however today when I tried to connect to Netflix, it failed. I logged onto the router and found my MTU settings had reverted back to 1500. So, if anyone has an opportunity to view the routers advance settings in the connection properties, Is "Auto Detection" related to the MTU Settings e.g. when auto detection is "on", will it change the MTU settings or is this related to something different.
Again, I still don't know the root cause but my fingers are starting to point at Verizon or ActionTec because the firmware had been the most recent change when my issue occured.
