I have a question about how often the time is synchronized when a WP7611 with R16 is used. I noted that after about a week, the time on the modem had drifted about 2 minutes into the future. Does the time only synchronize at startup, or did the network time drift? I had rebooted before and noted that drift was still there. But upon reboot today, I noted that the network time had corrected itself to match NTP servers. Thanks!
