Do you want to use CamRanger on an existing Wifi Network? The bridging features only works with CamRanger firmware 6 and up and the CamRanger app 2.0 and up. Refer to the Firmware Update section of the User Manual for further details about the firmware update. By clicking on the Connection/Network tab within the CamRanger Settings, the following will appear in the drop-down. The network setting allows the user to be connected to the CamRanger and an additional Internet network simultaneously. Previously when using the CamRanger, the iOS device could only be connected to the CamRanger WiFi network, making it so the user could not use any other network when the CamRanger was in use. Note that connection to an additional network may slow down the performance of the CamRanger.
To join an existing network, first connect to the CamRanger network from within the iOS settings and then start the CamRanger app. Select the ‘Settings’ button from within the CamRanger app and click on the ‘View/Edit’ tab. A dialog will appear listing any networks that the CamRanger sees. One can join a particular network by selecting the network of interest and then entering the password if necessary. The CamRanger will then attempt to join that network. Note that while connecting to the additional network the CamRanger network will momentarily disconnect. One should join the additional network before starting a CamRanger session, if attempted to do so during a session, this may disrupt the current session. The CamRanger cannot bridge with hidden Internet networks. Once one has connected to an additional network, this network will automatically be saved in the CamRanger settings. The additional networks will be listed at the bottom of the network dialog, “Known CamRanger Networks,” and can be accessed within the ‘View/Edit’ tab, within the ‘Connection/Network’ tab, found in the CamRanger ‘Settings’. 
Whenever the CamRanger is turned on, the CamRanger will attempt to join any of the known networks on the “Known CamRanger Networks” dialog list. If multiple networks are within range, it will join the network with the strongest signal. Networks can be added or deleted by selecting the ‘Edit’ button, found next to the “Known CamRanger Network” list. If one does not want the CamRanger to join to any networks on this list, it is recommended to delete them from the list. When the CamRanger is bridged to another network it provides two modes of operation. A device can connect to the CamRanger when that device is connected to either the CamRanger or bridged network. If the CamRanger is bridged to an Internet connected network, devices on the CamRanger network will be able to access the Internet. NOTE: If the CamRanger is not able to join a network, such as due to invalid password, it is possible that CamRanger does not create it its own network and the WiFi light will be off. If this occurs, power on the CamRanger on where it cannot access the bridged network or temporarily turn off the bridged network. Source: CamRanger
