6400 losing connection

Alan C

About once or twice a day SmartSDR loses connection with the 6400. I'm not doing anything, just  listening to 40 meters. It's the same LAN setup (four port switch) I had with my 6300. The 6300 never lost connection.

Look at your task manager under performance and watch the graph of the CPU utilization. If it hits 100% for a little bit. since it cant communicate it will loose the connection. If you have a separate graphics card less of a problem but have seen this happen. The graphics uses a lot of resources. More panadapters open the more the screen is constantly updated. Chrome kills my resources too. my video interface is onboard, not the best. SmartSDR seems to be more like a gaming computer than just internet and email. My computer is a Dell Laptop Inspiron I5 3210M processor with *GB of RAMM. I have to be careful what I have up on the screen or it runs out of CPU and disconnects the radio.

Bill, thanks for the suggestions. I did have FireFox open - and yes it takes it's share of the CPU resource. Graphics is built-in. At your suggestion I looked at Task Manager - CPU usage and it's just 6% total. However, Memory is at 51%!. Perhaps I should upgrade the 8GB to 16...

My ram always run around 4 out of the 8 gb I have. Probably not an issue. 6% is great. maybe a router issue. do you run direct computer to radio. If not may want to try that. I find that figuring what it take to reproduce the problem is 90% of the work.

Well, it's still losing connection. Lost connection twice this morning while doing nothing except receive.  I've rebooted the radio and the computer a couple of times - no change.

I've never hooked the radio up to the computer directly - hook it up to the LAN port, then?

Another thing you might check is under Device Manager.  Make sure that your LAN card is not set to "green" mode that turns it off when the system doesn't see a lot of activity.  Every once in a while, Windows 10 updates my system and sets my LAN card and other subsystems to green mode.  #$%^ tree huggers!

Alan, when you get the disconnect, what actions do you take to reconnect?  Just restart SmartSDR or do you have to shut down the radio.  If the later, does a short press of the power button shut the radio down?

Alan C

I just re-start SmartSDR. (Yes, a short press of the power button does shut it down nicely - I did that four days ago, and am leaving it on).

Turns out, it has worked perfectly for 4 straight days (leaving it on).

Restarting SmartSDR and reconnecting to the radio is usually indicative of a network issue where the client (SmartSDR) did not receive the keepalive packets from the radio for a period of time an initiated a disconnect.
