You haven't set the WiFi country, as indicated in one of the first replies to your post. Please do so before configuring WiFi - https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md.

Welcome to this forum. Please provide us with the information that is asked for in https://retropie.org.uk/forum/topic/3/read-this-first.

something seems off aobut Williamsmith007's reply, should it be flagged as spam?

@nastytone also you can use raspi-config to setup wifi I believe.

Thank you Mitu, and Herb. I have ordered a wifi dongle.

@ballboff I tried what you mentioned but nothing shows up but the same 2 options:
0
H hidden ESSID

I honestly don't think its something that simple. I logged in to my router to see if it would even pick up the Pi, unfortunately it's not.
Thanks for your input, I appreciate ALL the help I can get.

Thanks buddy
after checking again i saw the power supply was spitting out 4.3V+- so the wifi dongle was not powering properly.
I feel really dumb.

'power supply is now in trash'

@Dominus

Ha! Isn't that always the way it goes. I briefly looked for an iPhone equivalent, but didn't see anything off hand.
