Turning DLNA on makes devices loose Internet and hard drive access.

I have WNR3500Lv2 running "Tomato by Shibby for WNR3500Lv2 v111 (All In One) 111-AIO" firmware with usb hard drive connected to it.

From time to time when DLNA is turned on various devices connected to the router (TV, home theater, PC) loose access to the Internet as well as access to the usb hard drive connected to the router (accessed through SAMBA). It seems it happens more often whenever DLNA is being actually used (watching video from the hard drive on TV).

Does anyoneone have the same issue?

Any ideas how to fix/prevent this?
