One thing to try is turn off and disconnect power from your router (allow to exist in this state for at least 15 seconds). Also while the router is down, shut down/power down (or turn wifi off) on you laptop/computer and the camera. Connect power to your router and turn it on. Allow the router to reboot. (Watch your phone or other device to see when it has wifi signal again.) Then power up or turn wifi back on on your laptop/computer and the camera. Sometimes asynchronous encryption keys mean wifi devices lose touch with each other. Resets like this usually enable them to find one another again. Most often with older equipment, but just thought I'd throw this out there in case it helps.
