Computer hanging when multicasting

[kravicz]

Hi,
Every time Serviio multicasts, my computer freezes for a couple of seconds. I'm able to move the mouse, but when clicking or typing, the action is performed after these seconds. I'm attaching the detailed log.
Funny thing it didn't happen before.

nothing wrong in the log. try to upgrade your network card driver.

I updated the network card driver but the problem continues. I also tried to use just the wired network card and it still happens.
Another doubt, when I use the wireless card and I set my tv to find a dlna server to connect it takes a while to the server to appear (about a minute). When using the wired network, Serviio appears on my tv screen instantaneously as well as the windows media sharing service. Any ideas?
