Hello. My name is Michael. I can help you with your question.
What is telling you that the wlan card is bad?
If you are getting speeds like 30mbps, then it sounds like it is fine.
The MAC address shouldn't be all zeroes. What device has that mac address?
Thank you. IN that case, Vizio has a fix.
Let me know how you make out with them or if you have any issues contacting them.
