Hello, I'm new to Linux and recently installed Linux Mint 22.1 XFCE on an old notebook. At first, Wi-Fi works — it finds networks and connects normally.
But after a few minutes, the connection drops. When that happens, the computer doesn't detect any Wi-Fi networks at all.
Sometimes, if I restart the computer, it starts working again and networks appear. But then the Wi-Fi disconnects again after a while, and networks disappear once more.
Wired internet works fine.
