Hey guys,
I haven't had any of these problems as of yet with the new firmware. Just wondering; since you discovered that you have been upgraded to the new firmware, have you restored the device to factory defaults yet? I can't guarantee that it will fix your problem, but it's more of a habitual thing for me. Every time I get updated, I restore to factory default settings, and then stick the modem back into bridge mode. It might be superstition, but that's how I've always done things.
