Maestro Randomly Restarting
My Maestro running SmartSDR v1.9.13 has been randomly restarting. It doesn't completely restart, but the screen goes blank except for the slice A & B headers at the top, which are without any information. I hear my 6500 click as the relays change or dropout, whatever they do. After a few moments the Maestro comes back online all by itself. Typically when it does the frequencies aren't where I had them before the incident occurred and the display type changes, but other than that it is like it never happened.
Anybody else having this issue?

I do not see this behavior on the Maestro. I would suggest using a known good 12 V-DC supply and direct Ethernet direct. If the misbehavior is still present it's time to open a ticket.

The Ethernet connection should be able to drop out completely off and on and not cause a reboot or crash. Mine has crashed a few times using 1.9.13 doing the exact same thing as yours Moose. It doesn't go back to the previous location because I believe like regular Windows, it wasn't able to save this information prior to crashing. Yesterday it ran all day flawlessly, go figure.
Another issue I've had, that I only bring up here in case there is a commom cause, is that the DAX connection will drop out with no warning or error message. I only notice because the digital mode program I'm using stops receiving and the received signal level bottoms out but it usually takes me several minutes to notice this has happened. Restarting DAX fixes the issue.

This is the first time I have seen the restarting issue. I was using a battery when it happened on mine. If you go to the menu and then network at the bottom of the screen you will see the network statistics. I usually don't have many dropped packets but I had a lot yesterday and several times the green bars went to red and I had a lot of audio drops. I rarely had this happen in the past but this happened every few minutes yesterday, along with the Maestro restarting twice. I'm not sure if it has anything to do with the newest software but this is the first time I have used the Maestro since updating the software and I never had these issues before.

The only device intermediate of the two was a gigabit switch. Dudley advised that I replace it with a 100Mb switch. His explanation was that the 6300, when connected to the gigabit unit, auto detects the faster device and can produce so much data that, on occasion, it can overwhelm the switch creating a log jam and therefore latency and disconnect from the Maestro.
This advice seems counter intuitive to me but I followed his suggestion last week and put in a D-Link DES-1105 100Mb IP switch. Only the Maestro, 6300 and one network cable connect to this switch. The rest of my gigabit network remains as it was. So far it's six days later and I've had 100% up time with 24/7 power on.
Dudley also had some suggestions for gigabit switch models that would do better with the 6300 than mine did but I've lost track of the models as I had this slower unit on the shelf.

What can be done to keep this from happening?
73 Chris AK4SK
My 6300 & Maestro never reconnected on their own. Sometimes a crash would go over night and then I'd finally start things up again in the morning. These crashes were particularly frustrating when they occurred durring a QSO, which happened often until I got a handle on how to restart for the maximum trouble free result.
If I only restarted the Maestro, things would be fine for a few hours to maybe a full day. It didn't take long for me to learn that restarting both the 6300 and the Maestro would often result in several days of trouble free operation. The difference restarting both was obvious in the resulting time before the next crash occurred.
I've never had this happen when using my PC or Windows tablet and SSDR. Only when the Maestro is in use.

After reading about the switches, I realized that I did recently add a new switch to my wireless access point. I unplugged the 6700 from the switch and plugged it into one of the empty ports on my Netgear access point and ran the Maestro for about an hour. I only had a handful of packet drops so I think my problem could have been the switch. I will run the Maestro some more this weekend to see if that fixes the reboot problem.

Is there a way to completely reset or reload the firmware for the radio similar to reformatting a computer hard drive and loading everything fresh? Would that help?
73 Chris AK4SK
It is not a complete "wipe to the bare metal and start over" type reset, but it clears the databases and restores most of the default settings.
Chris,
Apparently if the radio disconnects it will reboot. Mine just now said on an Ethernet connection it could not find the radio (****??) even though it's been running fine all day, then the timer counted down and the Maestro rebooted to the "Select a Version" screen.
People can blame the network all they want, on Ethernet with no latency issues there is no excuse for the Maestro to lose connection to the radio unless either the radio or the Maestro started having internal networking issues or a firmware issue?
I powered the 6300 down and also powered down the Maestro and let them sit for 5 minutes.
They powered back up fine, so I'll let them run the rest of the day and we'll see.The other issue that seems strange is that some switches work and others don't. If the Maestro is adhering to standard Ethernet protocol, it should work with ANY switch that also adheres to those standards. I've run hundreds of devices off of 100/1000 switches and have never come across a device that would not work properly due to the switch being used.
There must be something that I just don't understand here.....
