Since the USB port isn't activated on my BGW320-505, how does one setup network storage ?

There are many Ethernet enabled NAS devices that you just connect to an Ethernet port on the BGW320 or anywhere on the local LAN or even Wi-Fi. I would personally skip Wi-Fi for a NAS device but they exist.

A quick google or Amazon search should find you a wide range of price / feature choices.

Western digital makes Ethernet storage devices I got a 6 terabyte device for 99 bucks 

why is the USB port not enabled to plug in any storage,.? can att tech support help enable it?

why not?, is the question,. is there any specific reason when the router comes with USB.. its all about giving the best features to the customers,. have them avail the best of the best in technology,. isnt it?

It’s for programming from the factory

Constructive, since you mentioned "Western digital makes Ethernet storage devices I got a 6 terabyte device for 99 bucks "...can you share the model # ?  Everything I find is much more than that.

Unless you've already had a NAS setup then the HDDs are cheap.

Thanks !

I got it on sale at Best Buy a couple weeks before Xmas 

CONSTRUCTIVE:  You said that the USB port is for "programming from the factory".  The manual describes it as a "USB 2.0" port but it does not say "Don't touch!  This is just for factory updates, you (Edited per community guidelines)."   Nearly every router I've had in the past provided USB attached storage from the router.   Seems AT&T is in the business of not giving a rats rear about its customers since (1) they didn't require Humax to post a note on this in their manual about this inactive port, and (2) it's employees can post to this forum a note that clearly shows disdain for AT&T customers.

You are welcome to try to use the USB port but it will not work for your purpose of attaching a USB Storage device, a USB printer or any other consumer USB product.

You just need a Storage device that connects to a computer and share from there or grab a Storage device that is a NAS and has an Ethernet port and software that provides a web interface for example.

Here are a couple of options from Bestbuy.com

Dave - thanks for the kind note.  I have been using a Western Digital external USB3 drive for quite some time both as attached storage to a former Netgear router and currently as a network shared drive on my current PC.  I was hoping to move it from my PC to the router as I had done in the past, but the USB2.0 port on the supplied Humax router unfortunately will not provide that functionality, at least not as one would suspect.  Thanks again.
