V.90
Ted Huf
Now that the new V.90 modem standard is out, do we have to wait for our ISP
to upgrade his end? If I am now using X2 and upgrade to V.90 before my ISP
does, how will my connect speeds be effected? In the same vain, what if my
ISP upgrades first?

Basically, yes. Unless your modem and his both support K56flex or both support
X2 (but that's not really a V.90 question).

They might improve, although apparently some folks who have already bought V.90
modems are reporting that things don't work as well as they used to (I'd
encourage you to find and read those threads). If this is true it certainly
wouldn't be by design.

Yes.

Hopefully not at all, but you might well have problems if the client code
is unstable. I strongly advise NOT upgrading until there is a good reason
to do so. "If it's not broke, don't fix it!"

Hopefully not at all, but you might have problems if the server code is
unstable. Pray that your ISP proceeds with great caution.
For that matter you might well have problems with V.90 at both ends of the
connection.

Unless you actually have an option to flash back to older firmware (which
was not provided on Sportster x2 modem updates), you could be stuck with
firmware that does not work as well.
As for x2 improvements, I think it's safe to assume that USR has been
putting all its energy into V.90, not x2, and that V.90 will soon be
touted as the fix for any/all x2 problems. (Likewise the K56 camp.)

Plus there's always the small possibility of "bricking" the modem due to
a failed flash. That happened recently with one Sportster model. I was
flashing my Courier recently only to have the power brownout a couple
minutes after it finished. Was I breathing a sigh of relief! That was
the incentive for me to finally get a UPS. :)

I think those are safe assumptions too.
