TC70 upgrade to Lollipop WLAN stops working

Hello everyone;

I have a problem with a TC70 device. Once I updated it, the WiFi stopped working. I know it is a knowing issue and I found out a solution to it but the URL is not longer available. Someone knows how to fix this problem? Has Zebra a link to this file?

The old URL is this https://portal.motorolasolutions.com/Support/US-EN/Resolution?solutionId=99267.

As you can see is a link to motorola older repositories.

Thanks in advance!
