I'm looking forward to buying a wireless router with a USB port, so that I can share my 1 TB external Hard Drive over Wi-Fi among my devices.
I came across one such router, TP-Link 3G/4G Wireless N router TL-MR3420.
The specifications say that it has a USB port for connecting a 3G/4G USB modem which is fine.
But in case I connect an external hard drive or a pen drive to the router instead of a USB modem, will I able to share the drive contents over Wi-Fi, as routers with USB ports but no support for USB modems do?
If yes, does it mean that all similar routers(with USB modem support) support file sharing too?
I know this is a basic question but I'm confused since no where on the site file sharing is mentioned and I'd like to know for sure before investing in it.
