The antenna connections for the Wi-Fi cards can loosen up and may cause unstable connections. To fix this, locate the Wi-Fi card on the motherboard and push down on the antenna connections on the card.

If the Wi-Fi issues still persist, then Wi-Fi card may be broken. This will require a replacement of the card. A repair guide can be found here (Repair guide is work in progress).
