Raspberry Pi WiFi Issues

[Shraddha]

Hey everyone,
I’m having some trouble with my Raspberry Pi 4’s WiFi and was hoping someone here might have some advice.
My Pi keeps dropping the WiFi connection or sometimes doesn’t even see the network at all. This happens no matter how close it is to the router or how strong the signal is. Rebooting sometimes helps, but the issue comes back. Ethernet works fine, so it’s definitely a WiFi problem. Could it be a hardware issue? How can I check?

Hello there,

I encountered the same issue with my Raspberry pi 3 and it was solved by following below
Go to the menu options.
Preferences -> Raspberry PI Configuration -> Localisation -> Set WiFi Country.
Set the country
Reboot

Check if this will help you.

A recent software update was made for the Pi4/Pi400 which can dramatically improve performance. In a terminal, type the following commands to update the software:
sudo apt update
sudo apt install firmware-brcm80211
The issue is solved!!!
