In order to upgrade your modem, you need to contact the developer and request the new package because there isn't an online resource available for this purpose. After you download the package, right-click on the Computer icon, select Manage and open Device Manager. Expand the Network adapters and Universal Serial Bus controllers lists, locate the MTN modem, right-click on its driver and select Update Driver Software. Use the Browse option to navigate to the downloaded files, select the driver and install it following the on-screen instructions.
