Reader Question:
“Hi Wally, Hello, and with all my respect, I ask for your help, I have a problem and I can not solve it, indeed since last week I tried to. connect my 3G usb key in my PC dell to connect but i can no longer and when i consulted the device manager this is what it ‘s showing me and the error that occurs in all the drivers that have a yellow triangle is the error 10 I need your urgent help please. (pictures attached)” – O. Aloui., France

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: 3G internet USB devices (dongles) can be very convenient. However, there are times when they don’t work. It can be very annoying to see a problem like this especially at a time when customer support may not be able to help you. e.g. the holidays.

Don’t worry though. If the error can be fixed from your side, then we will try to help you get your internet back right now. Let’s get started!

This problem is usually caused by driver issues or damage to the 3G USB device.


Here are some ways to fix a problematic 3G USB dongle:

Uninstall And Then Reinstall The 3G USB’s Driver

If the problem was the driver, then you can it by uninstalling and then reinstalling the driver.

Press the Windows Key and type programs.

Select Add or Remove Programs or Programs and Features from the list as shown below.

Remove The Driver From Device Manager

If the driver was not available here, then you can remove it from Device Manager. Press the Windows Key and type device manager to search for it. Click Device Manager from the list of search results.

In the Device Manager window, look for the 3G USB device. Right-click it and click Uninstall to remove it.

Read The Manual of The Device

If you don’t have the paper manual anymore, then you can download the manual from the internet. You can do this by searching for the exact make and model of the device and the keyword manual.

e.g. “Huawei 38372 Manual”

3G USB -- Make and Model - Internet USB - small - Windows Wally

Open the manual and look for troubleshooting instructions. Are there any instructions in there about the lights of the device? The manual should help you understand what’s really happening.

Contact The Internet Service Provider For Further Assistance

Call your internet service provider’s Helpline number and explain the problem so that they can assist you.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
