TEW-443PI does not work

3 posts in this topic

Recommended Posts

Hi I want to use the Trendnet TEW-443PI wireless card, but it does not work.

I found this in the web but how can I finde out the device and vendor id ??? is this the Mac adress ?


I have TEW-443PI, and it works perfectly out of the box. You should edit /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortAtheros5424.kext/Contents/Info.plist with your device and vendor ID to have support.

This card does work perfectly and you dont need any extra LAN cards. I'm posting this so people can refer back as I cant find the answer anywhere on GOOGLE.


My Device ID is [168c:0013]

1. Install Mac OS X with no extra network drivers.

2. Open Utilities -> Directory Utility and press the lock button (type password)

3. Edit -> Enable Root User (type a password you will remember)
