[SOLVED] Network disconnects while playing

Hi all.
I have a problem that started happening a few days ago, and so far I couldn't find a solution online.
This is my setup:
Router: Bewan iBox C5200 (http://www.bewan.eu/produit.php?page=produit&parm1=bw-iboxc5200)
PC: LG laptop
TV: Samsung UE37C5100 connected via LAN to a different router
Different router: Linksys WRT54GL with custom firmware by DD-WRT which enables it to be in client mode.

So the streaming process is like this: PC <wifi> Bewan router <wifi> Linksys router <lan> TV
This worked perfectly for about a month - I could watch full length movies in 1080p without giving it a second thought.
Last week I started to get during random intervals, but always while watching a movie, a message on the TV: "Network disconnected".
The message disappears after few seconds, and then it send me back to the folder I played the movie from.
I can immediately play the same file again or any other - but the problem still occurs.
I should mention the length or the format of the file makes no difference.

Attached is a LOG snapshot in DEBUG mode during one of these errors.
Can anyone help me? This drives me nuts!

Thanks in advance,
Shai.

you're going through 2 wifi networks, there is a possibility of connection problems. Possibly you're sharing the same wifi channel with neighbours?

I'll try to change the channel and let you know if it helps

try to google for tools that will scan your wifi neighborhood and tell you which channels are less used

Well, after few hours of movie watching - I can gladly declare that changing channel (from Automatic to 9) worked!
Thanks a lot, I really appreciate your help
