said by swintec:I have that same firmware and it has been working perfect since March or April when I activated it. Our of curiosity, does your modem show any upstream bonding?
Looking at the admin menus, I think the answer to your question is no .. there's only one upstream channel bonded (#4) .. where there are 4 channels in the downstream "bonding" table.
Got TWC coming out in a few hours. Hope they find something, or I'll need to return this modem, get a new one.
