Yeaaaa, all the DPC line hides the log. I guess Cox loads a config that disables it. ::grumble:: In their defense though, the way the firmware is set up, they can either block almost everything, or give you full admin control. There is not the normal user middle ground. And since they didn't want people messing around with different freq locks on the different channel bands and messing with their traffic management system, they locked it. Thats one story anyway. Others say they had too many reports of people posting logs online with their personal MAC addresses. I don't really buy that, because why just that one modem?
Anyway, yes, if you have someone on the inside, have them check your logs and signal history. Also have them check your street for any trends of the T3 errors. Even if not relevant with your current problem, its good to track down anyway.
