Is it possible to use a router to connect and transfer data between devices?

You can transfer files between any of the devices like Android, Windows Pc..etc.

You can directly use LAN cable as well but with router you can send and receive files with all computers connected to the router.

Use ftp server,homegroup,local file sharing on windows for file transfer.

STEPS:

Connect the devices to the router through LAN/ Wi-Fi

Windows:

Using folder sharing files can be transferred between two PC's.

PC 1/ Source computer

1. Select the folder/drive to be shared
2. Press alt + enter for properties window
3. Go to sharing tab and select advanced sharing
4. Select the check box "share this folder"
5. Press OK and close the properties window

PC 2

1. Press win + E to open explorer
2. Right click -> Add network location -> Next

Enter the address of PC1 in the following format

\\••••••••••••••\sharedFolderName

Examples:

\\192.168.1.156\Users

Here 192.168.1.156 is IP address of shared PC and Users is the shared folder

Find IP address:

1. Press win+ R, type cmd & press enter
2. Type ipconfig & press enter
3. Find the address corresponding to the connection being used

Windows to Windows can be done without router and just with a single Ethernet cable. This is faster than the former method
