SunSDR2PRO "Stuck" on default IP address 13 Nov 2021 05:03 #1

Not sure what has happened, but my SUNSDR2PRO seems to be "Stuck" on the default IP address. I Have attempted to change,to 192.168.0.200 without success. The Software indicates my new address in both in the ip display and on the expert tab. When setting on the expert tab it does display my new address, However, when I shut it down and then reconnect, the software still displays the new settings, But "Discover" remains at the default. I cannot connect to the radio. I have tried a reset of the radio with no joy. Any suggestions will be helpful! Thanks, Paul K9BOJ

If you cannot connect to the radio, it might be because the IP has in fact changed, to a different subnet that your current subnet mask does not allow you to reach. You may have to adjust your subnet mask to allow discovery - maybe 255.255.0.0 in the TCP/IP settings.

What is your local machine IP and subnet? Assuming that you were able to discover the radio previously, you might have been on the 192.168.16.xxx IP pool and/or your subnet mask was at least 255.255.0.0 to allow that discovery. If your subnet mask was 255.255.255.0 and you changed from the radio from 192.168.16.200 to 192.168.0.200, your local machine may no longer be able to see that new IP because it resides on a different subnet.

Thanks for the suggestion. I should have thought of that as I was an IT manager for 20 years. Funny how much you forget after 5 years retired! :) 73, Paul

Posting a "solution" to the "Stuck" default address in a SunSDR2Pro. As I mentioned in a previous post, I was suddenly unable to change the IP address of the transceiver to 192.186.0.200. A simple solution was suggested to simply open the address Mask which allows more access to the network. From my workstation at 192.168.0.119 and Mask at 255.255.0.0, I was now able to flawlessly open the transceiver that remains at the default address of 192.168.16.200. A simple solution to a perplexing problem. I am now on the air with both EESDR2 and EESDR3 Beta with no problems. Good luck to all. Hope this suggestion is of use to you'all. Paul K9BOJ :D :D

Here is a safer solution than weakening the subnet mask. It is applicable to my situation where a cheap subrouter was introduced in order that my Flex would play well with my other rigs. See the attached diagram of my shack topology. I merely changed the LAN addresses of the subrouter to 192.168.16.xxx with the standard subnet mask of 255.255.255.0.

Sub router or switch?
A Sub router is an absolutely bad idea.
Your drawing shows a switch - which is the normal practice.

Right Double NATing is a very poor thing to do
