Below are the most common questions
concerning V.90.
Check here frequently to see if any new solutions arise.
-
What kind of performance can you expect with
V.90?
-
How do I upgrade my modem to V.90?
-
What is the basic requirement that is needed
to upgrade to V.90 standard?
-
How do I update my K56-Flex or X2 modem to run V.90?
-
Will I be able to connect to IOLS at V.90
speed?
-
Will upgrading to V.90 make my X2 modem
K56-Flex-compatible or make my K56-flex modem X2-compatible?
-
If I upgraded my K56-Flex to V.90, will i still be
able to connect to K56-Flex modems at 56K speeds?
-
I upgraded my modem to V.90 or I bought a modem that
is V.90 compatible, but it does not connect at V.90?
-
My V.90 modem will not connect at all with IOLS.
-
The computer you
dialed is not answering...
-
I am getting disconnected from the server
after a few minutes?
With a reasonably good
phone line and if you live within 3 1/2 miles from your central office
(local phone company building), you should get connect speeds between
40K and 53K. Some lines have impairments on them, like digital pads or
robbed bit signaling (RBS), which decreases the highest achievable
speeds. However, if you are getting pretty good V34 connections, you
should be able to significantly benefit from a V90 modem.
Please contact the
manufacturer of either your PC, Mac or modem and ask for an update or
upgrade. In most case it's as simple as a download. For a list of manufacturers or vendors please
click here.
1. Flash upgradeable
firmware. Please check with your hardware vendor.
2. Most vendors have promised to deliver software upgrades for
V.90Flex.
For most modems, simply
download the flash utility software and upgrade. Other modems may
vary. You may have to confirm if your modem vendor has a V.90 upgrade
for your modem.
If you've connected to
IOLS using K56Flex, you should be able to connect to V.90 speed once
you upgrade your modem to V.90.
No. V.90, K56 and X2 are 3
distinct protocols.
If I
upgraded my K56-Flex to V.90, will I still be able to connect to
K56-Flex modems at 56K speeds?
It depends on the EPROM in
the model as sufficient memory space to hold codes for both modulation
(K56 and V.90).Please check with your model vendor.
When people run into this
problem, they usually assume that either their modem doesn't work, or
our modems don't work. Neither is necessarily true. When your modem
first attempts to connect with us, (this is when you hear the initial
tones), our servers then determine your baud rate. Under ideal
circumstances (meaning that the modem has a clean connection with us),
your V.90 modem will connect with us between 40K and 53K. If you're
getting speeds under 40K then you may want to consider the integrity
of your phone line (Read FAQ, "What kind
of performance can you expect with V.90?"). If you're more
than 4 miles away from your local provider, you may not be getting the
integrity our servers need to establish anything over 40K. In this
case, contact your local provider and ask them to test your lines and
how they function with a data connection. Another possible solution is
to download the latest firmware that the manufacturer distributes via
the manufacturer's home page. These simple installs should increase
your speeds.
Find the error message you
received below. Then follow the steps given to solve the problem.
Error 629
This generally means that
you are not entering a user name or password that is understood by our
servers.
All Platforms: re-type the
user name and password in the script or the Connect to screen
in Windows. This will reset the script and most of the time fixes the
629 problem.
You may be cancelled from
the ISP or the password or user name has changed. Call tech support
for more information.
The computer you
dialed is not answering...
-
Always retry your
connection when you first get this error. In most cases your modem
simply does not connect right the first time.
-
There might be busy
signals - To find out, manually dial the local number to see if
you hear a busy signal or related. If not, retry your call.
-
There may be a problem
with connection integrity. If our server cannot define your modem,
it will disconnect you. This may be caused by your line integrity,
or common V.90 issues. If so, a temporary solution that we find
useful is to use two commas at the end of the local number.
This will connect you at a lower speed, but at the same time, gain
the integrity needed to stay online.
-
In rare cases, we
found that it might be handy to re-install your TCP/IP protocol if
you are using Windows. Browse our tech support pages to see how
this is done.
The only permanent
solution that we've found was to upgrade your Dial-Up Networking
to version 1.2. This has been proven to prevent
disconnects. Please go to http://windowsupdate.microsoft.com
and perform all critical updates recommended by the online utility
provided by Microsoft.
