This seems like a power or SD card problem.
What are you using for a power supply?
What kind of SD card are you using?
Try writing a Raspbian image
to an SD card with Etcher
, then adding a wpa_supplicant.conf file to the small FAT32 "boot" partition before using the card in your Pi4. Do not extract the image from the .zip archive before writing, Etcher will do that for you. If you receive any errors during card creation, verify the SHA256 hash sum of your downloaded Raspbian .zip file.
The wpa_supplicant.conf file should contain the following information.
Code: Select all
Edit country=, ssid= and psk= with your information and save the file.
Use the 2 letter country abbreviation in CAPS.
Use a pure text editor (like Notepad++) to edit the file (not a word processor).
With that file in the small FAT32 "boot" partition of the Raspbian imaged card, WiFi should connect when you boot up.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
