WWAN card keeps disappearing from available networks list


My problem is with a GOBI 4000 Sierra WWAN card.

It is installed and activated just fine and works whenever I choose to connect to it.

The problem is that (see screenshots) whenever the computer goes to Sleep and then awakes back up, the "View Available Wireless Networks" list no longer shows the WWAN card as an option to connect.

To resolve the issue, I go to my network adapters and disable/re-enable the Sierra card.

Immediately after that it shows back up in the list of available wireless networks and I can connect.

So how do I solve this problem of it disappearing like that after the laptop Sleeps or sits in Hibernation for an extended period of time?

Thanks for your help.

In device manager->properties for the device is there a power tab? Something like "allow windows to turn off this device to save power" you can uncheck?

I took some screen shots of the device in devicemanager. There is nothing as simple as a check box for that option unfortunately.

I took some screen shots to show the Sierra WWAN card in device manager and the available tabs.

There is this "power data" variable that looks interesting but may be nothing.

Thanks for looking. (see attached)

Usually there is a tab called power if the driver supports it, so looking for better drivers would be my first step.

This one is even newer, it says win8 32bit but those always work on win7

This looks like a newer firmware for the device:

This didn't resolve the "exact" problem, but it is a solution. I say it didn't resolve the exact problem because I still have issues with the adapter not displaying in available networks after coming back from Sleep mode.


This documentation "ReadMe.txt" file on the link you provided did give some insight to an alternative way to control the connection.

By using ThinkPad Access Manager I am now able to just right click the access manager application (in the task bar area) and select to connect to Verizon using the WWAN card.

This is not the exact method I wanted but it works and it's easy and I think my user will be happy with this solution.


- If you use ThinkVantage Access Connections, the following software must be

  [Windows 7]

  - ThinkVantage Access Connections for Windows 7
      version 5.52 or higher
  - ThinkPad Power Management Driver for Windows 98 SE/Me/2000/XP/Vista/7
      version 1.62 or higher
  - Hotkey Features Integration for Windows 7/Vista/XP/2000
      version 3.50.0000 or higher.

Thanks for your help.
