Update Drivers of your ZTE EV-DO Modem in Vista and Windows 7 for better Speed

win7_box_image Recently i wrote a post as how i acquired my EVDO and Tips and tricks to get better speed ,  but later i realized that i am getting better speeds on my brothers laptop running on Vista where mine is on Windows 7 ultimate. The ZTE modem provided by BSNL comes with no software update for Windows 7 , but we can do that manually.

Steps to Update EVDO Drivers in Windows 7 System :

  1. Right click My Computer.
  2. Click on properties and then select Device Manager from top left
  3. In Device manager view open Ports (COM & LPT)
  4. In the dropdown list select ZTE Diagnostic Ports
  5. Right click and select Update Driver Software
  6. Choose Update from the Internet.
  7. Now click on “Modems” in Device manager.
  8. Then again select “ZTE USB Modem” and Right click and go to it’s properties, and repeat the Automatic Update process which we did previously with the Diagnostic Interface driver.
  9. Wait for the update and upon completion restart your pc for the changes to take place.
