Ummm yea! That comment reminds me about all of the V.90 modem woes
I was experiencing awhile back.
I had an older Zoom 56k modem that seemed to work just fine with my _old_
ISP. Then I changed ISPs, and I started to see frequent problems. Some-
times the modem would just seem to take a little nap for about 30 seconds
or so. (Perhaps it was doing that retraining/renegotiation thing. I'm
not sure.) But other times, I would just abruptly lose carrier for no
apparent reason. (This was an external modem, so I could watch the
various LEDs.)
Of course, at first I blamed my new ISP. I figured that _they_ were doing
something wrong because the modem had woked just fine with my prior ISP.
So I called them up and started giving their tech support folks a hard
time... in a friendly way of course. :-)
The only idea/theory/suggestion that they came up with was that I must
have a modem with Rockwell 56K chipset in it, and they said that they
had had a number of problems with people using Rockwell-based modems
because (they alleged) the Rockwell chipset was less than perfect, and
because it didn't play well with the Lucent-chipset-based stuff that
they had in their Portmasters.
OK, so I run down to the local computer store and I'm looking for a
_new_ V.90 modem with a *Lucent* chipset. The only one they had was
a newer version of the same bloody Zoom modem I already have. Now I
already don't like Zoom, because their tech support sucks, but I buy
one of these new Zoom modems with the Lucent chipset anyway.
Result: I have _never_ had a single problem since.
The only problem I have now is finding the time to list the old (Rockwell-
based) modem on eBay. :-)
P.S. Please DO NOT flame me for any of the above. I most definitely
DO NOT own stock in either Lucent or Rockwell, and I would be the first
one to admit that I have absolutely NO IDEA for sure what exactly was
causing my earlier problems with the Rockwell-based Zoom modem. For
all I know, it was working fine and I just had it configured wrong.
I'm just telling the story, as it happened.
P.P.S. More info:
Model # of old modem: Zoom 2849
Model # of new modem: Zoom 2949L
