How can I fix my WiFi connection problem?

[AC Question]

I just had my samsung galaxy s4 screen repaired and ever since I have had trouble with connecting to my WiFi, keeps dropping out.
Any ideas what it might be?

Welcome to Android Central! Perhaps the wi-fi antenna was damaged, or a connection loosened, during the screen replacement. Can you take it back to the shop where you had it fixed?
