The maintenance and service guide for 8200 convertible shows Wi-Fi part 538048-001 on page 21

Please confirm you have a PCIe card with two antennas sticking out the back of your PC.

The driver download page for your system list a Jan 16, 2015 driver for the Ralink 802.11n which is an old card (win7 win8)

Before installing or downloading anything please bring up the device manager and look for your wlan or wi-fi card and see if you can find the manufacturer and spot any errors.  If Ralink shows up and errors are indicated then try the above driver

For example, my "killer wifi" is a Qualcomm Atheros and driver version and date are shown.

Some 8200 are custom and you might have a different WiFi card than that listed by that manual.

If you have that old Ralink you might want to consider replacing it with a newer WiFI that supports 5ghz band and also does bluetooth.
