EDIT: A Firmware update has been released for the modem. More Details Here

I own the D-Link DWM-156 modem, which worked well with Windows 7, Windows 8.1 and, up until now, Windows 10. My 3G connection serves as a backup connection – I use it when the WiFi at my place is extremely slow (we have 2Mbps uncapped ADSL which is shared with other students), or when I feel like playing some computer games online. It was late September when I started noticing my modem does not work with Windows 10 – I get a warning message saying the application (D-Link Connection Manager) has been blocked for my protection. My User Account Control always stays off (its the first thing I turn off when I install windows – that UAC message box annoys me).

While I appreciate Windows 10, taking extra steps in ensuring the software that runs on my computer can be trusted, I am annoyed my 3G modem doesn’t work, the usual way – I do not want to spend money on another 3G modem, when LTE is going to launch in the next couple of months (or years, if Cell C covers my area last).

I have tried this online guide, which supposedly addresses the issue: http://www.ibtimes.co.uk/windows-10-how-fix-this-app-has-been-blocked-your-protection-error-1516240 

I followed the steps and it did not resolve the problem. I did a bit of Googling, and apparently, D-Link’s code signing keys were leaked. Would Microsoft be blocking all software that uses the “leaked” data? That I am not sure of. What I find works each time, is if I run the application at “Admin” level, through command prompt (wish there was a way of creating some script which does the entire process).

The first thing to do, is to right click the start icon, and select “Command Prompt (Admin)” – this launches Command Prompt, at an Administrator Level.

Right click the start button, and select Command Prompt (Admin).
Right click the start button, and select Command Prompt (Admin).

The next thing you need to do, is to find where you have the D-Link software installed. The software I have is “D-Link Connection Manager” and it is installed under: C:\Program Files (x86)\D-Link Connection Manager (This location may differ depending on your PC configuration). After you have found the install location, go to command prompt and type “cd C:\Program Files(x86)\D-Link Connection Manager“. This will change the directory to where the application is installed.

The last step would be to launch the application from Command Prompt (at Admin Level). If you go back to the place where you have the D-Link software installed, you should find an .exe file – that is the what you will launch from Command prompt. In my case, the name of the file is WirelessModem 

After locating the name of the application, go back to Command Prompt and type: WirelessModem.exe and hit enter. After a few seconds, the application should launch. This is what works for me every time.

I really hope the guys at D-Link attend to this issue, if they are at fault. I really don’t want to spend money on another 3G modem… I am waiting for LTE after all 😀
