Upgraded to SSDR 2.0 yesterday, and successfully registered, but was running an Apple Airport that was a bit flaky. Decided to upgrade to a LINKSYS AC5400, which has UPNP, and is the very latest technology. Now SSDR says it successfully registered, but both TCP and UDP say "FAIL". I have a feeling that I should UNREGISTER and then REREGISTER to solve this. Comments?
Somehow, the radio is telling the Flex server that is is on the wrong subnet. I just have one router here, and the COMPUTER is on 192.168.1.116, but the RADIO is reporting that it is on 192.168.7.53. That is on the wrong subnet. The computer is talking to the radio, but when I try to use Smartlink, i guess that the Smartlink server thinks the radio is on a nonexistent subnet.
To answer the thread title question, the only problem that would be fixed by unregistering/re-registering the radio is with which account to associate the radio. This is completely separate from connection issues which is what the Test button gives some visibility. Connection issues usually point to network related issues that must be resolved in your local network configuration (radio side network, not the client side remote network).
