Since I replaced the screen to my LG G2 I have had a low wifi signal, how could this have happened?

Replaced LG G2 Screen and Now Have Low Wifi Signal

After replacing the screen I am getting low wifi signal. Whereas I would initially get full bars in my room, I am only getting one bar. Does anyone know what could have possibly gone wrong, or where the wifi detector within the phone is?

Check the cable going from the motherboard to the antenna. You may have pinched it or disconnected it. (The "wifi detector" is part of the motherboard.)
