WIFI Routing of External HDD

i wish to connect my External Hard Disk (1TB) to a wifi router which would allow me to access files wirelessly using my Samsung Tab 2.
please inform me if the purpose would be solved by using iBall Baton iB-WRR300N, if not pls suggest which router should i buy. i need the router for personal use and not commercial, hence pls suggest an inexpensive one
