Yes — that’s normal when the camera is acting as the Wi‑Fi hotspot. Your phone can only use one Wi‑Fi connection at a time, so when it joins the GoPro’s network, it leaves your normal internet Wi‑Fi. Since the GoPro network is only for camera control/file transfer and doesn’t provide internet access, the phone reports “no internet.”

To use internet again, disconnect the phone from the GoPro’s Wi‑Fi and reconnect to a normal network or mobile data.

This behavior is common with cameras that create their own Wi‑Fi network. Some cameras also support an “infrastructure mode,” where both the camera and phone connect through an existing Wi‑Fi network, which can allow app control without losing internet. If your setup is using the GoPro’s direct Wi‑Fi connection, though, losing internet access on that Wi‑Fi connection is expected.
