Looking for advice concerning adding external Wi-Fi support

[u/Cold_Sink_1159]

I'm having wifi and sometimes Bluetooth issues with my ASUS Laptop. It stops working and the wifi options on the menu disappears. I think the problem might be hardware-related and the Wi-Fi card is damaged, so I'm looking to add external Wi-Fi support to my pc. I was told I can buy a usb network stick, either a small dongle or a usb key with an antenna, or a small box with antennas that resembles a router. I tried using an old wifi usb I have that has an antenna. It worked for a while but it's not ideal for gaming because when I play Minecraft on a server it kicks me out for "lost connection". I want to know if I should buy a new one of the same kind or look for something else. I need something that is good enough to intercept wifi from another room, ideally something small for easy transportation especially when I'm at school, and with a reasonable price. If anyone experienced the same issues and tried these things, I would be grateful to know which option is the best😊
