Re: [vox-tech] my hub just died

Wasn't someone going to setup the voxtech return address correctly?  What
happened?

Anyways...

Yeah, around 100Mb/sec.

Well, ... yes.  But, the fat-telephone like connectors are categorized
into several categories.  Category 3 (Cat3) is good enough for 10baseT, I
think.  10BaseT uses only four lines out of the eight on the Cat3 cable, I
think (send, receive, ground, and... something else).  Because it doesn't
use all the lines, you can deliver two 10baseT transmissions on a single
Cat5 cable using a splitter (maybe you can with a Cat3 cable also, but I'm
not sure).

100baseT also uses the fat-telephone like connectors, but it must be
Cat5.  100baseT uses 6 lines of the 8, I think, and cannot be
splitted.  Or at least that's my understanding.

Approximately, yes.

Yes, it does matter.  My terrible hub, for example, can only do 100baseT
(100Mb/sec).  10baseT doesn't work.

I saw 100/10 dual speed hub at Fry's for $30 something... I think
$35... maybe $39.99...
