Smartlink test fails revisited


Good day, all and thanks for your patience with an old issue.

I was required to reset my cable modem and wireless router for an isp issue. After the reset, I port forwarded ports 4993 and 4994 to my Flex internal ip. All flex functions are good with wired and wifi connections within my network. I have been unable to reestablish Smartlink service on either my Maestro or SmartSDR ios. I have unregistered and reregistered my Smartlink account and have logged out and back in successfully. However, the Smartlink test continues to fail.

It appears that I may have something missing in the modem/router reset.

Suggestions appreciated.

73, Bob, KN4HH

    The way I fixed mine. I turned on UPnP in the router.

    I would recommend going back to Section 9 of the SmartSDR manual and walking through all the steps. After a reset, there is no guarantee that the radio IP address is the same. You do not have to create a new SmartLink account or logging in or out. It is rebooting the radio that normally resolves things.

    If your cable modem supports uPNP and it is enabled, doing a full reboot on the radio will cause the radio to send the commands to the router for the correct settings.

    If you must do a manual setup, then you will have to review all the settings on the Router and make sure it forwards to the right IP address for the radio.

    We do recommend leaving uPNP enabled on your router and then if you have any issue, usually rebooting the radio and router solves everything.

    This video goes through your situation.

    Thanks Mike and Ed. I needed the networking 101 you provided, Mike. I had two settings to adjust. I did not properly assign the forwarded ports. I had UDP and TCP ports reversed. Also, I had to assign a static ip address for the radio. All is well.

    Many thanks for this valuable Community.
