I paid for the app on Google Play store, but the app is not installed

One of the frequent questions we get on our support channel is the issue with Payments on Google Play store. Our WiFi Pro FTP Server is one of the top paid apps in Tools category and some users have faced issues with getting the app on Google Play store. Users in India opting for UPI payments typically face this issue. The payment transaction completes successfully and user’s money (Rs. 10) is debited from their bank account, but the transaction fails at Google’s end and the user does not get the app. This leads to a frustrating user experience and unfortunately most users think that the app developer is withholding the money. This is not true. All payments on Google Play store are handled by Google and the developers get paid mid of next month with amount accrued over the previous month.

If you face this above issue and could not get the app after money is debited (via UPI payment), please wait for a few hours. Google will auto refund your amount in a few hours (sometimes this may take 1 business day). Post that try installing the app again.

WiFi FTP Server keeps changing IP Address

One of the frequent complaints/suggestions we get about our WiFi FTP Server (pro) app is about the change in IP address of the server. We wanted to clarify a few points about IP address, how it is controlled, and what role (if any) the app plays in managing the IP address. We also have a few suggestions on what you could do assign a fixed/static IP address.

Every device connected to a WiFi network (using TCP/IP stack) would be assigned an IP address by the DHCP Server. In a typical home WiFi network, the DHCP server resides in the WiFi router. Most WiFi router DHCP servers are configured to assign a dynamic IP address to each device connected to the router. Depending on the DHCP server settings, the IP address may change at periodic intervals. Once an IP address is assigned to a mobile device, all apps using the WiFi network interface use the same IP address. This IP address assignment is not controlled by the WiFi FTP Server app or any such similar app.

When the IP address of the mobile device changes, users will have to change the IP address in the FTP clients they are using (ex: Windows Explorer, FileZilla etc…). We recognise that changing IP address in the client is inconvenient and frustrating to users. Here are some ways to avoid this issue and have a fixed/static IP address for the mobile device

  • If you are using a WiFi router and connect your mobile device and PC to the same WiFi router, go to the WiFi router’s admin page, locate the DHCP server settings and assign a static IP address to your mobile device. The location of DHCP server varies by WiFi router (and its manufacturer). Following is a screenshot of the DHCP Server from the admin page of TP-Link AC1200 router

Locate your device from the DHCP client list, note down the MAC address of your device and then assign a fixed IP address to that device from the “Address Reservation” section.

  • If you are using Windows 10 PC/Laptop Hotspot feature to create a WiFi network between the mobile device and your PC, then follow the steps in the below video to try and assign a static IP address from the Android mobile device
  • If you are using Android WiFi tethering (Mobile hotspot) to create a WiFi network and connect to this network from your PC, then the IP address assigned by the Android hotspot is 192.168.43.1. However, some Realme/Redmi devices assignin random IP address when a mobile hotspot is created. This is specific to a few Android device manufacturers and there is no solution to this problem. The IP address will change every time the hotspot is changed. Future versions of the WiFi FTP Server app will display the IP adress/FTP URL as a QR code to help users scan the QR code from the client.
