8.31 driver - Procomp laptops & desktops driver download. may be offered by Microsoft Windows Update or supplied by system manufacturer. The 8.31 driver was a special build for an Agere customer that fixes an obscure problem not likely to be encountered by most users. Because this driver did not undergo the testing normally done with general driver releases, Agere is not making this a general release and it won't appear at Modemsite. So, why is it on Windows Update? [When a driver is submitted to Microsoft's WHQL for testing and driver signature, the submitter indicates whether the driver is to be made available via Windows update.] Should you upgrade to 8.31? [It's safer to stay with 8.30.]

Windows Update - Caution! As of 7-Oct-03, the Microsoft Windows Update site may offer version 8.30. In Mar-03, Microsoft added driver version 8.27 to Windows Update for XP. 8.27 is a special build that ISG Driver Download for Windows 102. disables V.92 and V.44 to prevent a rare compatibility issue that will be addressed in a later release. This isn't a good choice for anyone wanting to use 'the latest and greatest'. XP users may find this driver automatically installed depending upon Windows Update settings! Also see: 22-Mar-03 V.92 News.

The latest version may not work as well as older versions for some people. Use the version that's best for you & archive your current version. If you are getting 28.8k or lower connects with old driver, the new driver might give you a big boost -or- it might cause you to get an even lower connect rate. If you get a lower connect with the latest driver, see Trouble with the LTon this page, the Troubleshooting Page, or revert back to the older driver you were using before the update. The handshake sound has changed with version 5.49.

Note: With driver version 5.44 & higher, the .inf file renames the modem from'LT Win Modem' to 'Lucent Win Modem'. If your modem is renamed, you will need toadjust Dial-Up Networking connections.

* - The 6.04 (and 8.12) generic, as well as some vendor-specific downloads are available from the Windows Update Site for WindowsXP. If you have XP and a Microsoft-recognized LT modem, the Windows Update Site should allow you to download these drivers when you scan for updates. If you are not running XP, it appears to be impossible to get this update from Microsoft - see the 16-Feb-02 Latest Update. (The package is available as a zipped file from Modemsite.com's Premium Access Content.) The driver package does not include support for Win9x, or NT. See THIS PAGE for more information.
