Thanks for the info.
I've seen that site before so I might check it out.
My router/modem has a log. Its loaded with errors I can't interpret. I
googled a portion of it and landed on TWC forums.
Missing BP Configuration Setting TLV

-p/1016
Didn't see much of an answer.
Hopefully it's a temporary thing as it just started. I don't think it's a
problem on my end, maybe, but doubt it. I'll give it another day or so.
Thanks!!
