Connecting an External Hard Drive to a Wireless Router

[sp123me]

Hi, I currently own a 1TB Seagate external Hard drive which I want to connect to a modem router

External HDD: Seagate Expansion external Hard drive Seagate Expansion External Drives | Seagate
Router: Netcomm ADSL+2 Wireless N300 Modem Router http://www.tpg.com.au/helpdesk/pppoe...mm_NB_304N.pdf

Which I want to connect together so I can use my External Hard drive as a network storage device in which I can access using several wired/wireless computers

The Wireless router HAS a USB connection point in the back, as well as mentioned on the box of the router "USB port to connect an external Hard drive", but the problem is the instructions are rubbish, and I can't find much info on the router itself, (came together in a bundle with a tpg broadband plan)

Spoiler:

So my question is how do I get it connected?
I have windows 7 on the computers I want to access the HDD

Connect hdd to usb port.

On computer go to "Computer -> Network" and in the list you should have a device listed there with a name "Router" or router model. If there is no authentication you should be able just open it.

It should be listed in computers but might be different for your router. Check router settings.
