Mike, Nope, 5100 and 5150 are docsis 2.0 only. They'll still "work", just only at 15mb/s and down (unless they figure out a 2.5 hack or some such). Docsis 3.0 is its own new beast all together. Another round of modems for everyone! At least for 3.0 goodness. -mb On Wed, 2009-07-29 at 08:09 -0400, mike havens wrote: > will the sb5100 still be usable? > > On Tue, Jul 28, 2009 at 11:31 PM, Michael Butash > wrote: > David, > > No, sorry to say, but you can't upgrade via firmware.
