Readynas Duo V2 issue - RAIDar constant blue light #23802186

Hi all,

hoping to get some guidance - although i have a very basic understanding of tech talk!

I have a readynas duo V2 hooked up to a TP Link modem and my samsung smart TV.

I have had the above up and running smoothly for 2 years, however late last week i noticed the connection really slowing down to the point where now i can no longer connect to my NAS through either the ip address in chrome or through the network drive that i mapped.

RAIDar still picks up the readynas, however on the left hand side is a constant blue light (not flashing). Info bar quotes "File system check, 100%"

I have tried OS-reinstall but to no avail...

I also have getflix set up, however this shouldnt be an issue i am led to believe (?!) it was all running smoothly for months like this.

any tips would be really great!

cheers
