wireshark only shows youtube app packets for smartphones.

edit

Hello guys, I have a TP Link archer c50 wifi router. My desktop is connected via rj45 cable with router. I also have a laptop which has Realtek 8821CE wifi adapter. The problem is wireshark doesn't detects any packets which are passing through smartphones web browser. If i filter by ip source it shows nothing for smartphones but when i open ''youtube app'' it shows some activity. But i want to capture those packets which are passing through web browse. Can any one help me out here?
