PLEASE HELP !!!!
I purchased a lot of pi3's 25 of them for a project I want to do and it was a great deal. The problem is the wifi is not working and I've spent hours trying to figure it out. I have been through too many pages to even know where I have been basic things I've tried
apt-get update
apt-get upgrade
rpi-update
formatting and reinstalling noobs numerous times
different pi units
differents sd cards (new and used)
a working sd card out of my personal pi in the hardware I bought


please need some serious help, Im pulling out my hair trying to figure this out

What does 'dmesg' have to say about it? Are you installing Raspbian light or the full version?

The problem is the wifi is not working

What does that mean, precisely?

Do you see the network configuration icon at the top right of the GUI Desktop? (Usually two opposing up/down arrows) Does that give you the option of entering your WiFi credentials?

Do your credentials fail? Is there anything about the WiFi network that could explain this? (Have you asked the Network Administrator?)

rpi-update is probably not going to be part of the solution, and for consistency it would be better if your fault-finding was done on a standard current release of Raspbian, as installed by the current version of the NOOBS Installer.
