Can you test with a Lan Cable plugged directly from the radio to the computer and no switch?

Yes, re start your network, and restart the radio and computer to make sure everything is in sink. There are no known issues with this update that would cause this.

Unless you try some of the suggestions offered it is very hard to help you.
The health bars on the bottem of the screen must be green.

You have not restarted your router, radio, and computer?
Connecting as you are you should see all green,,marginal can have dropouts

To the contrary, I did all of that re-initializing .  Are you looking at the photos I posted. I am experiencing ZERO dropouts. I have 5 green bars with Excellent network status. I trust you grasp what I am stating. Thank you.

Bob K8RC

The FIRST photo you listed had YELLOW bars.
Congratulations on fixing your problem.

Bob: Now I grasp what you were referring to. I did not see that I was experiencing a network latency problem.  Thanks for giving me the heads up on the bars.
I made the following changes. I originally had the Ethernet cable from the 6600 to teh Cisco SG 200-08P Gigabit smart switch. The switch had an Ethernet cable feeding it from the router. Then a third ethernet cable went to the network Ethernet input of the computer. I first had the 6600 cable go directly into the computer network input. I restarted everything. The problem took about 5 minutes to occur. After reading some of the replies, I next decided to eliminate the Cisco switch completely. Fortunately, my computer has TWO network ethernet inputs.  I connected an Ethernet cable directly from the router to the computer.  So in summary, there is a direct connection from the 6600 to the computer and another direct connection from the router to the computer. As I write this post, SmartSDR is running and it shows 5 green bars. That is excellent! The black bar problem is not occurring. Bob, thanks kindly for your assistance.

 Hi ... Sky ... Do you have a name or a Callsign?

There are a few things that make this happen, in order of likelyhood.

• LAN cables - yes, they go bad and I had 1 just last week that was causing CW skimmer to crash.  This was the cable between the radio and the switch.  I could recreate it at will and I posted online regarding it.  Sounds like you tried that and replaced them with new.  That is the easy stuff to try
• The switch - Some switches work better than other - this is why we do the computer NIC cable to Radio test.  If that fails we are down to 2 parts
• The NIC card on the radio and the NIC card on the computer.

NIC cards on computers can be  problematic (speaking from a professional career in data backup) and you radio will likely stress your computer NIC card more than anything else as we are now talking real time streaming data and we notice drop outs that are very short, and hence the black bars and loss of signal.  With that in mind, can you check the following:

• make sure the drivers on your NIC card are fully up to date - you can do this in device manager
• When the drop outs happen, can you watch the CPU monitor in task manager?  We want to make sure the computer is not 'resource bound' and it doesn't have something else steeling cycles that is causing it not to be able to service the data from the NIC card
• Turn off your AntiVirus as AV is very very resource heavy - we want to do this as a test to eliminate being resource bound - Google DPC Latency testing 
• How much  memory on the computer?  Are you using more memory that  physically installed?
• How old is the computer hardware, and the reason I ask this is that if the harddrive is old (great than 3 years), the harddrive might be failing and in a constant state of repair.  When this happens, you can see the computer do a big slow down as the hard drive isn't available to do things 
• Lastly, defective NIC on the radio.  I haven't see one yet.

Based all I have read so far, it looks like your PC is resource bound.  That is where I would focus based on everything else I have seen so far.
