Good that you are making the backup, but ...
If memory serves, the OS reload would only help if you weren't getting any Live service at all. Typically, the problem you describe is at most handled by the reboot to drums trick. What I'm wondering is where you are, and whether your local 'cell' service conditions are degrading.
When you view the cell connection menu (Main Screen, R arrow, R arrow, Status & Information, Version Information, Network ), what are you seeing for signal strength where you are? How many of the 5 bars are showing blue, and are you waiting a long time between "Connecting" and "Connected"? We need to find out whether the problem is your unit, the TT server, or local connectivity issues. For now, I'd hold off on that OS reload business.
