How to choose & set up WiFi wireless card for SDconnect C4

This is all about how to use WiFi for MB Star diagnostic using SD connect c4 multiplexer.

Part 1: How to choose Sd connect c4 wireless cards

If I replace or upgrade the PCMCIA wireless card in my SDconnect, do I need to change the driver? If so, does anyone know how?

No, you dont have to, just atheros compatible wifi card is fine.

Netgear WG511T
Netgear WPN511 (several reports)
TP-LINK TL-WN610G
D-Link DWL-G650 (firmware B 2.23 or greater like C series or D series)
Cisco Aironet CB21AG

There are possibly other based on Atheros 5212 that will work but you’re doing this at your own risk If you make it work please report here!

D-link DWL-645
NEC Aterm wl54ag

Well, I can tell you what doesn’t work: Netgear WN511B. This is a RangeMax Wireless-N 2.4GHz 802.11n card that “works with Windows Vista”. Woohoo! (But it doesn’t work with SDconnect C4.)

The card fits, but the C4 mux thinks it’s connected by a LAN cable. The “S” shape for the connection appears, but not the broadcast symbol.

Oh, well, it was on $5 USD from Amazon. Too bad

Part 2: How to setup SDconnect WIFI connection

Click wireless network icon to select “View Available Wireless Network”.

Click “Refresh network list”.

Click “Change advanced settings”.

Select Wireless Network.

Tick on “Use Windows to configure my wireless network setting”.

Click Add.

Enter Network name.

Tick on “Connection even if this network is not broadcasting”.

Cancel tick on “The key is provided for me automatically”.

Tick on “This is a computer-to-computer (ad hoc) network; wireless access points are not used”

Enter network key and confirm it. (network key: 26 a)

Go to Connection and tick on “correct when this internet is in range”, then click OK.

Click OK.

Enter the network key and click Connect.

Click the red circle in the menu bar.

Select Configuration and then click Yes.

Select MUX>> Register/Configure.

Select Encryption: WEP/Hex and enter the key (26 “a”s), then click Start.

Click OK.

Close Administration interface.

And you will see the network set just now is connected.

Done!
