Troubleshooting • Raspberry Pi 3B v1.2 wifi not working

Hi and thanks for reading!

TL;DR: I may have fried the wifi chip of my Pi, but I don't know if it may be a router issue?

So I just flashed a new image onto my Raspberry Pi 3B v1.2 (32-bit lite to be exact) to clean stuff up and get a fresh start. But now it won't connect to wifi!

I had been able to connect to wifi before, but a few minutes prior, I had tried to install a touchscreen display. However the Pi was still on, and I think the DSI pins may have touched the wrong touchscreen pins. The red power LED went off, but once I installed the display right, it came back on. Everything looked good. This is when I flashed the new image. Then I tried to run but I got a bunch of warnings that the URLs it was trying to pull from gave temporary failures.

However, when running , the wifi IP address does not show up in the wlan0 section. I've inserted my correct wifi SSID and password into , but it just errors out. I'm 99.99% sure I have the right SSID and password. When using , I get no results. returns nothing, and wifi isn't blocked. The wpa_supplicant file contains the correct country code, SSID, and password of my network. Running returns no errors, and I'm fairly certain the driver is loaded. Again, this is a brand-new image from the official imager. The wifi didn't work on a previous image, either. returns wlan0, if i remember correctly. Pinging google.com gives a "temporary failure."

What do you think is the issue? Could it be router-related or is my wifi chip cooked?
Thanks!
