Give me a better understanding if tranfering photo to a cell phone or to a destop computer or to a laptop computer or tablet.
The idea of wifi LAN is that in a certain place the connection between camera and any device is between router and devices are using the same router in any local area network. If you move to another place, you must do wifi LAN of that place. A new connection must be made. I suggested to rename the camera because the default camera is already used, but sometimes it worked. When the camera is moved to a different place, camera gives a different SSID and password ( correct me if i am wrong ) or I have noticed that SSID and key after one month or more is changed ( pentax camera ) at least one or two character/s is changed. See at the camera the recent SSID and password to be entered in a new location to your device.
There is also a big change if the device wfi LAN is in another country.
