Connection problems (URL not working)
Slow file transfer
Directory not writeable
Forgot access password
'WiFi not connected' error despite active connection
Folder upload not working
URL keeps changing
WiFi File Transfer starts/stops by itself
If the URL provided by the app does not work in the browser of your computer, there's usually some kind of connectivity problem between the Android device and the computer. Please refer to the flowchart below to eliminate the most common culprits. If you're still experiencing the same problem after working through the steps in the flowchart, please take a look at the 'Network problems' section below.
If your browser is still unable to connect to the URL, there may be a problem with the network environment. Common causes include:
- Firewall/Security software on the device blocking incoming network connections
- Certan browser plugins that redirect browser requests
- One of the devices being connected to a VPN
- Improper configuration of multiple routers on the same network
- Improper configuration of device IP and subnet settings, especially when using static IP addresses instead of DHCP
If one of those may apply to you, please don't hesitate to contact us for further assistance.
If you're seeing a license error message inside the app even though you have purchased WiFi File Transfer Pro, please uninstall the app and re-install it from Google Play. This should solve the problem permanently. In case it does not, please don't hesitate to contact us.
Depending on the speed of your WiFi network and your Android device, you should see transfer speeds of 1 to 6 MB/sec. If you're getting significantly less than that, please refer to the flowchart below.
There are two possible reasons for this message:
1) You're inside a system folder that is write-protected by the operating system. Click the 'internal storage' link to change to a writeable user folder.
2) If you're inside a folder that is supposed to be writeable and this message is shown, then the file system of the device has probably stopped functioning properly. A device restart normally fixes this.
If you can no longer remember the access password to the web interface, simply open the settings of the app and enter a new password, or delete the current password from the password field to disable password protection altogether. We strongly recommend setting an access password if you intend to use the app on wifi networks shared with others.
Certain Samsung Galaxy devices running Android 2.3.4 or later have a firmware bug that causes WiFi problems under certain circumstances. These problems include periodic disconnects as well as incorrect reports about the status of the connection. This occurs if your WiFi router gives out DHCP leases that never expire. To solve this problem, open the configuration interface of your WiFi router, open the DHCP settings and set the DHCP lease time to 14 days. After restarting both the router and the Android device, the WiFi connection should be more stable and apps should be able to detect the status reliably.
Browser support for this useful feature is still in its infancy, unfortunately, and at this stage Google Chrome is the only browser that allows entire folder structures to be uploaded. Please note that this is not a restriction imposed by us.
If you would like to transfer entire folders and your current browser does not support this feature, we recommend using Google Chrome.
The URL is the local IP address of your device, and the IP address is assigned to the device by your wifi router when the device connects to the network. Most routers are smart enough to remember devices that have previously been connected to the network and will assign the same IP address when a device connects to the network again, but with other routers the IP address (and as a result the URL provided by the app) changes each time the device connects to the network.
If your router does this and you would like to maintain the same URL, please check the DHCP settings of your router. Most routers have an option to reserve a particular IP address for a particular device. If your router does not have this option, it may help to forward a random unused port to the current IP address of your device. Because the port forward would become useless if the IP address kept changing, a lot of routers will let devices keep the same IP if there is a port forwarded to the device.
This may happen if you have enabled the AutoStart function in the settings of the app. If you wish to disable this feature, tap the 'Home Network' setting and choose 'AutoStart off'. When AutoStart is enabled, the app will start automatically when your Android device connects to the configured home network, and stop automatically when this network is out of range.
