Wifi low signal

[itihashero]

My laptop since it's motherboard was repaired.... While using wifi it automatically has very low signal of wifi and the application I am using also hangs... For example: if I am using Chrome and the laptop suddenly gets weak signal Chrome also hangs with the whole laptop... And its the laptop o lyrics that gets weak signal from time to time whereas other mobile phones are perfectly working
