Can't connect to my NAS LS-CH anymore

[Lagartija]

Hi,
I can't see /find or connect to my NAS anymore,
i tried,
"connect to server"+smb://IP adress,
NAS Navigator 2 can't see it,
IP address in the browser can't connect
reboot- the Link station....
Nothing....

IMAC/ Mac OS 10.11.6
IP adress 192.168.1.2
Router 192.168.1.1 Huawei DN82455X6
connected via LAN/ethernet

LS-CH used to be 192.168.1.15

Everything was working fine for ages but since I changed my router, nothing....
Is there a way i could just try an connect the Link station directly to the mac via ethernet, i just need to back up some files ( i tried sharing but doesn't seemed to work too...)

Thanks for your help,
Cheers
