How to configure SD Connect C4 Wifi on Win10 Win7 XP

SD Connect C4 Wifi Configuration mainly depend on which version of C4 and what the computer operation system (win10 or win7 or XP). MB SD C4 Plus DoIP wifi Configuration is very simple, after the computer searches for the wifi signal, enter the password 123456789, you don’t need to set anything else, and you don’t need to set the WIFI IP address.

How to configure MB SD C4 DoIP WiFi connection?

For the other version of SD Connect C4,you need set up WiFi connection SDConnect “WORKSHOP” for Windows 8, 10.

Windows 8 and Windows 10, unlike Windows 7, do not allow you to create a direct computer – to-computer (Road24) connection. However, it is possible to create an Ad-hoc “WORKSHOP” network between the computer and the SDConnect multiplexer in the command line mode. Not all Wi-Fi adapters support this type of connection. This is why you first need to make sure that the laptop adapter allows you to create an Ad-hoc network.

Open the command prompt as administrator: press Win+X, Command prompt (Admin).

Enter the command netsh wlan show drivers and press enter. In the list that opens, look for the item “Hosted network supported”, which should have the parameter “Yes”.

If this function has the “no” option, then either the wrong wifi adapter driver is installed, or this adapter does not support this type of connection.
Next, create the network “workshop” with the command: netsh wlan set hostednetwork mode=allow ssid=”workshop” key=”aaaaaaaa”. Where “workshop” is the network name, “aaaaaaaa” is the password. The network is created.

The network is created once. The command to create the network do not need more. In the future, only the commands to start and stop the network are used.
Start the network “workshop” command: netsh wlan start hostednetwork. The network is up.
Open the folder “Network connections”. We see that there is a virtual adapter Local area connection **.

For convenience, it is desirable to rename the virtual adapter to “workshop”.

Next, you need to assign a static IP address and subnet mask to the virtual adapter. This is done with the command: netsh interface ip set address name=”workshop” static
Press enter. There should be no error message. Check if the adapter settings are saved in the adapter properties.

At this point, the virtual network adapter configuration is complete and the laptop is waiting for the SD Connect multiplexer to connect.
To stop the network, use the command: netsh wlan stop hostednetwork. The virtual adapter disappears in the Network connections folder .

For convenience, so as not to enter commands manually, you can create bat files with the appropriate commands. Files are created in any text editor with any name. After that, its are assigned the extension bat.

The network creation file has the following contents:
netsh wlan set hostednetwork mode=allow ssid=”workshop” key=”aaaaaaaa”

The startup file of the network and assign an IP address:
netsh wlan start hostednetwork
netsh interface ip set address name=”workshop” static

Network stop file:
netsh wlan stop hostednetwork

The network creation file is used only once. Network start and stop files can be conveniently located on the desktop.

Next, you need to configure the SD Connect multiplexer.

Connect the multiplexer to the laptop by cable. The lan adapter settings must already be installed.

Run” SDConnect Administration”.

Go to the tab “Registration/configuration”. Enter the data according to the screenshot and click Start

The multiplexer configuration is complete.

If the multiplexer has already been configured mode Road24h, now added the second mode is a “workshop” and have the opportunity to switch modes wireless connection. On the multiplexer, the switching of wireless connection modes is performed by the buttons of the display panel.

In the ” workshop” mode , constantly flashing, red led means that the device is waiting for connection with the laptop. As soon as you run the bat file “network start” on the laptop, the connection will be established automatically and the led will stop flashing. The order of starting the network in the laptop and turning on the multiplexer in the ” workshop” mode does not matter.

Stopping the network is performed as a bat file. In this case, the multiplexer again goes into the network connection wait.


1. On Win7 / XP

To change the Road24h connection to your usual network, some old adapters need to disable and enable the network adapter in the .bat.

2. On WIN10

no need to disable and enable old adapters.

Win 10 Test report: Run batch files with administrator rights on my Windows 10 and works fine. Name of wifi connection must be the same in batch and in network section in control panel.

***Experience for sharing: In my old Toshiba with Intel PRO Wireless 3945ABG it is necessary to disable and enable old adapters, otherwise it is not able to change from the standard network to the adhoc network. And I am using WIN10.

So it will enable and disable the card before apply new IP, no matter old or new pc!!!
