Wifi Extender and ReadyShare

[optheatre]

Wifi Ext WN3000RPv3

Router DGN2200

I've recently got an extender which works really well at extending the signal but I can't access any files on the USB ReadyShare Drive attached to the router.

I can't find anywhere where it says you can't do this but neither can I find anywhere claiming you can so thanks for any help at all!

How do you access the files?

The extender shouldn't be preventing you from accessing it.

I access it via a shortcut on my Windows 7 desktop which works fine if connected directly to the router (and in near proximity) but if I use the same shortcut when connected via the extender then I get a popup saying 'Network Error' 'Windows cannot access \\READYSHARE\USB_Storage'.
