Connecting and Sharing
As connecting an external hard disk drive is likely to give you the best results, such a device should probably be the type you use to test the feasibility of using your router as part of a wireless network media storage hub.
Connection should ideally take place while your router is switched off, or else restart the router after your storage device has been connected and powered on. At this stage you will need to return to your computer to check whether or not you can access the data on the drive through the router.
For the best results, begin by opening your router via the web browser, which is typically done by entering http://ROUTERIP. You can find the IP address of your router in Windows by pressing WINDOWS+R, entering cmd and using the ipconfig command -- the router IP address is the one listed as Gateway. After logging into your router, you should find a function that enables sharing of content, so activate this. You may also need to restart your computer.
After setting this up, you should be able to see the new storage on your network. If not, use the standard features of your operating system to add the device as a new drive, assigning it a letter and treating it as a local drive.
With your hard disk drive or other external mass storage device hooked up to your wireless router, you will be able to enjoy the content stored on it from any suitable network-connected device in your home.
