Subject: Re: Sbhacker Cable Modems at PLUG HackFest RoundUp
Ok I have a stock surfboard. I already have most of the diags, (Save
upstream power level). Now - it would be cool to walk the tree, that I
will admit. As far as increased speed.... Well, I would like to know
how that is obtained unless you are by passing an artificial lock set
by the ISP - unfortunately that is not my case - I get crap speed no
matter what package I am on.
