We've had some issues with TSR-310s and Ruckus APs that manifested as the TSR-310 being unresponsive and then randomly "catching up" on all the missed presses.
Your description sounds more like what happens when something isn't right with Authentication/SSL/SetCSAuthentication. Does the TSR's IP Table show online?
The bit about using a IP-ID from a TSW makes me doubt the relevance of my issues. Is the .sgd the program is referencing what is loaded on the TSR?
