Network Problems

[IanCardiff]

My Samsung  49 UMU6400Q  TV connects to the internet but does not find any other network devices, which it previously found and other Samsung TV's I have find. At the moment the TV is on a wired connection, but I have tried it on Wireless and get the same result...it connects to the internet but does not find other network devices  i.e. my NAS drives.

Any suggestions?

I have restarted everything several times

I have now solved this problem by renaming the tv name without any special characters in it like @, " or anything like that or just use simple alphabet to rename it. 
Also unplugging the TV from power for 30 seconds seemed to help.
