SmartSDR 2.3.9 Network Disconnect

Mike VE3CKO

Hi Lloyd, one thing I forgot to mention in the email is to ask if each Ubiquity radio is grounded at the radio. The purpose of the ground is to discharge any build up of static electricity, yes it does happen. 1's and 0's get confused, cats and dogs start dating, it gets messy.

Lloyd, what frequency range does the Ubiqity router operate in? I’m wondering if, being in a marina environment, it might get overwhelmed with occasional radar signals? The same way slower/older WiFi routers can be impacted by microwave ovens or such nearby. Just a thought.

It's on ch 160 --5800 Mhz, John.
I'm trying to get Ubiquity's Airview to work to look at the spectrum. Problem is it's legacy software and I haven't found a computer to run it on.

Cheers!

Maybe out in left field... I, too, had a “disconnect” problem with my 6600 as soon as I got it. Random intervals, no seeming common factor. Turns out that the RCA plug I used for remote on/off was flakey. The rig would be commanded off (and lose connection to the PC) if the dogs barked too loud or the temperature changed. Replacing the connector (or disabling remote on/off) fixed the problem. Took me months of looking in the wrong direction before the light came on! On the plus side, I am VERY sure about my LAN and data cabling.

Weird...… George did your screen say connection lost or did radio turn off?

Got a “connection lost” message. Had the front panel “waves” turned off, so didn’t immediately recognize the radio turning off, which it did after a few seconds.

I took your advice, George, and removed the USB/solid state relay device from the server to the rear connection on the Flex 6500.  Once restarted, the radio ran fine in remote for four days. 

After the latest crash, the same behavior occurred.  The SmartSDR program was not able to communicate with the Flex.  However, the listing in the opening dialog box did show the radio present. 

  

Therefore, the Flex is able to broadcast its presence on my VPN network, but not able to pass data packets to my end of the connection and the SSDR program.  

I know if I go the the server site and use the front panel power on toggle switch, all will be good again.

I should have reported this earlier, but I have apparently solved my disconnect problem by eliminating a reserved address for the 6700 in the router and just letting DHCP assign one. I also changed my lease time from 120 minutes to 48 hours. I am not sure which change fixed the problem, but at least it is fixed!!!

Ed, 

Glad you found your issue with the network drops on your network.   Router reservations normally are not a bad thing,  I normally will leave the radio in DHCP mode, but use the router or DHCP server reservation to assign the unique IP address to the radio MAC address.  Extending the lease time is not a bad ideal also. 

Enjoy,
