Macbook cannot detect D-Link DWM-156(A7) USB modem after upgrading to OS X Yosemite ver 10.10

Have you checked for new software from D-Link?

I figured it out!

I had the same problem with the dongle sent to me by Telkom South Africa.

Mine was D-Link Model: DWM-157. Here's how I fixed it.

I basically flashed or updated the firmware on the dongle to the latest one I got from the D-Link website.

1. You need access to a PC (Windows computer).

2. Go to: http://www.dlink.com/uk/en/support/product/dwm-157-3g-hspa-plus-usb-adapter

3. Scroll down and download firmware version 4.5.4.7

4. Once download is complete, move over to your windows PC. Plug in the D-Link USB dongle.

5. Run the firmware update on the Windows PC while the USB Dongle is plugged, Follow the prompts, it takes a little while, sometimes it seems like it is stuck but be patient. Once its done it will ask you to press any key to continue.

6. After the install, pull out the dongle and plug it back in, sometimes the device installation prompt will appear. If so, rerun the device installation again. Wait for all the drivers to install. If not open d-link connection manager on your windows PC and test if it is able to make a connection to the internet. If the test was successful go to #7 below.

7. Go to your Mac. Uninstall the current D-Link connection manager your have.

8. Plug the USB Dongle back, the installation prompt will pop up again.

9. Go through the installation steps and a prompt will pop up asking you to restart, restart your machine.

10. Run D-Link connection manager and you can now get to the connection screen. Wait a while for network to be found.

11. Click connect.

12. Come back here and tell us if this worked for you. It certainly worked for me.

Worked like a dream. Thank you so much!!

Unfortunately even after installing new firmware according to instructions above my Dlink DWM 157 can not connect to the internet. Everything works on Windows PC. When I try connect on macbook I receive such message: "Network connection, the connection failed because you have not entered a telephone number".

Thanks in advance

i tried all of your steps but when i try it on the macbook finally it shows that installation failed. I have a macbook pro retina 2014, D link DWM 157.

Work like a charm.

I'd like to provide some details as below:

I'd stuck at "no usb modem connected" message for 2 days, and unfortunately to me that my other pc has just been upgrade to Windows 10, which doesn't work with D-link 156. After getting the idea of upgrading firmware, I've tried few time and the computer saids: "no USB COM detected".

After few times failed, I started thinking that the issue caused by Windows 10, it somehow prevent Dlink driver to be installed.

My next step: bring the PC back to W7 (luckily I have a liteon, just took me 1hr to fully deploy W7). The new firmware upgrading program work successful.

The USB went back to my Macbook, it still doesn't work 😟

I uninstall the previous D-link connection manager, reinstall. Woohoo!!!! The connection window popping up, deadly happy.

So, in short the steps are:

- Get the latest firmware from Dlink home page.

- Try to find a PC with Windows 7 (the firmware upgrading program doesnt work on Windows 10). Make the USB dongle upgraded.

- Uninstall Dlink connection manager (if you already installed it).

- Reinstall the connection manager.

- Enjoy it.

Below is my result:
