samsung bd c6800 keeps disconnecting - tried all solutions

Hi - i'm new to the forums, but i've read a lot of posts here. my blu ray player (using player C/D profile) keeps disconnecting from Serviio. starts playing a movie fine but randomly (sometimes 1 minute, sometimes 5 minutes) into the movie says device disconnected. I have no such issues on my Samsung TV (using generic profile).

I have a Netgear wireless router WGR614v10. and Serviio is running on a MAC OSX.
player IP is 192.168.2.58
MAC IP (Serviio) is 192.168.2.51

I had my blu ray on wireless, and now tried with wired connection - still the same issue. I have already reserved the IP address on my router for the player & the MAC. but no luck i would really appreciate if someone could help out...

i do not have eyeconnect (never had) or hamachi

thanks a lot!
