this was driving me nuts - the same old problem after upgrade to 1.02.21 - unable to access “network shares” folders on my NAS (it was fine on Windows 7 PC - but no use to me). Also accessing Media Servers worked fine (with DLNA turned on on the NAS, or with Twonky - but I don’t like either of those as it has to re-index new content.)
I tried various things - factory reset in the options, clearing old logon info etc.
I had my USB stick with old firmware to hand and was just about to roll back when I thought about pressing the reset button on the side of the box.
That has done the trick (for me at least).
After that, the first attempted connection to “Network Shares”, selecting my NAS, prompted me for a username and password - and now it connects fine.
Of course it has buggered up my thumbnails but…
I hope this helps - in fact I created an account here just to help out the frustrated others.
Reset factory setting (no joy)
Pressed the hardware reset.
Reselected Video > Network Shares
Input username and password for NAS.
Bingo! :smileyvery-happy: :smileyvery-happy:
