I recently had issues reinstalling drivers for my Verizon 1x-EVDO embedded modem in my Lenovo Thinkpad X60, Sierra Wirelsss MC5720 Modem, couldn’t find much help, eventually found one messageboard that helped me out. Thus, I post my discoveries in hopes to help the next one out there. Pass it on, right?
So my issue – I reinstalled Windows Vista and was able to get every driver for my system installed without issues from the Lenovo driver website. However, for the life of me, I couldn’t get Windows to accept the driver location of Lenovo’s recommended driver download for the Sierra modem, thus rendering Access Connections and Verizon’s EZAccess programs useless. Well here’s how.
- Download Sierra Driver: This is the driver file I used, downloaded and used as of this posting. There may be a more recent version on Lenovo’s website – Sierra Wireless MC5720 Driver – MC5720AC.MSI
- Don’t install the MSI file!! Just download it and save it to your desktop.
- Use a program such as Universal Extractor to extract all of the contained files from within the MSI file. .MSI files are essentially a type of .ZIP or .TAR file in that they are a container for multiple files.
- Once all of the files are extracted, go to your Device Manager and right-click on the Sierra Wireless MC5720 that is listed under the Unknown Devices and choose Update Driver.
- At the prompt, tell Windows to look in the folder of the extracted files from the .MSI file
- Success! Once the primary driver is installed, there will be four or five other network device and comm port drivers that can be installed the exact same way.
