No, nothing seems to have improved overall. After I left it to run untouched for a hour I checked and it's not showing NAS devices again. I then shut every device off and rebooted router, NAS then one wired computer and my idea of the default ip range doesn't seem to have fixed this problem. With only the router, Diskstation NAS and a wired computer and still the wired Diskstation shows up as a media device but not a NAS that can be used. I can log into the Diskstation UI through it's ip address and access the same NAS on my iPhone via wifi. Nothing changed as I turned on a wifi laptop, wired printer and another older NAS by LaCie that also used to be visible but doesn't stay visible. I'm out of ideas. Too bad cause I like Dlink stuff but this isn't fixable IMO. I'm far from being a network expert and would welcome other ideas but I got to get something that works soon. Thanks
