There are only two scenarios that would cause this to happen after a screen replacement.
1. Too much pressure while connecting the connectors, resulting in a cracked solder ball under the Wi-Fi IC. I have never seen this happen.
2. You have put the wrong size screws in the shield (long screw damage) this is the most likely scenario. Check the left bottom screw hole I bet you can see copper.
