How to fix the error Configuration timeout for Ezlink on the Foscam App?

Overview: Setting up a camera with the Foscam app for a wireless network involves connecting a cellphone to the same wireless network. Normally during this process, the login information for the wireless network is sent to the camera and the camera logs into the network at the end of the procedure. Once completed, the camera is listed as one of the devices available to access from the app.
If something goes wrong with the procedure a user may encounter the error message “Sorry, your camera has failed to be added, Configuration time out for Ezlink.”  
To correct this error message, follow the steps below.
Step 1: Perform a hard reset of the camera to make sure the camera is in Ezlink mode and you will hear camera saying "ready for WiFi configuration" if your camera has built-in micphone and speaker.
Step 2: Confirm that the cellphone is connected to the same wireless network that the camera is supposed to be connected to.
• Note: Disabling cellular data may make the configuration process easier to perform.
Step 3: Verify the frequency band of the wireless network is 2.4 GHz if your camera only supports 2.4GHz wireless. If your camera supports dual-band wireless, your cellphone can connect to either 2.4GHz or 5.0GHz wireless.
Step 4: During the setup process, please maintain a distance between the phone, camera, and wireless network around 2-5 meters (6-15 feet.) 
• The camera can be placed in the place intended for installation after the network configuration steps are completed.
Step 5: Confirm the password for the wireless network has been properly input into the configuration settings of the Foscam App.
• The use of special characters for the wireless network password may cause connection difficulties. If there are repeated problems being encountered with a password using special characters @()*^&*(&*^% consider changing the wireless password to something containing letters and numbers only..
• NOTE: In the event the password is changed for the wireless network all devices that were connected to that network will need to have their password information updated to connect in the future.
Step 6: Check to see if the MAC ID filter is enabled on the router.
• If the MAC ID filter is enabled only the devices authorized to be connected to the router have access to the network.
• The work around is to temporarily disable the filter to allow the camera to connect. Once the camera is connected add it’s wireless MAC ID to the filter and re-enable the filter.
Step 7: Check to see if the router is running the latest firmware update.
• Visit the Support page for the wireless router at the manufacturers web site. Some earlier versions of firmware and some routers may prevent the wireless procedure from sending the login information to the camera. 
• Some routers may block this process and a different means of sending the login information to the camera will need to be implemented.
Step 8: If all the above steps fail connect the camera with an Ethernet cable to the router so it can access the wired network. 
• Allow the camera to establish a connection to the network via the Ethernet cable.
• Add the camera to the Foscam App, once added navigate through the app and setup the camera for a wireless network using the app.
• Download our Quick Reference Guide for your camera for this alternative setup process for the camera to connect to the network. Once the camera is setup with the login information for this network it will not have to be done unless a notable change to the network occurs or a new router is installed in the future. (New network password, new network name, etc.)
