I recently received my Raspberry Pi and i've just updated and upgraded the os and now the wifi doesn't work anymore. It says there is no wifi interface, its like wifi doesn't exist any more on the device. Any ideas? Should i just get a fresh version of raspbian and install it?
If you're having trouble with WiFi after updating your Raspberry Pi OS, the best solution is to download the latest version of Raspberry Pi OS from the Raspberry Pi website and install it on your device. This will ensure that you have the latest drivers and firmware for your device, which will help ensure that your WiFi connection is working properly.
You can download the latest version of Raspberry Pi OS from: https://www.raspberrypi.org/downloads/raspberry-pi-os/
Once you've downloaded the latest version, you can install it on your device using the instructions on the Raspberry Pi website.
You could also try extracting the latest drivers from the latest version of Raspberry Pi OS, but this could be more time consuming and potentially lead to more issues.
