I’d just updated an old Dell laptop with the latest version of Linux Mint. But the Wi-Fi reception was poor and didn’t connect if I moved it more than a few meters from the router.
Time to pull it apart.
The plate at the top of the keyboard comes off (there is a small recess on the right to lift it with a screwdriver). A couple of screws later and the keyboard comes out revealing the Wi-Fi daughter board. There were two connections that go into the screen hinge as the antenna.
One of these connections wasn’t quite right so I put it back in. Then a quick reboot and a connection was possible from the other side of the room:
Happy dayz. As to the root cause of all of this? It was probably one of my previous efforts of pulling the laptop apart and bumping the cable 😦
