If you get issues with tomatousb (as I did) give dd-wrt a try I have had no issues with my ttv and inet since moving from tomatousb to dd-wrt. I have the rt-n16 as well and I was having issues with my recordings and Inet speeds. when I had 2 or 3 recordings set my Inet would drop altogether and the video on the recordings was choppy.
SVN revision 19519 mega you will need to throw this batch of code into the command section and save startup: iptables -t nat -A POSTROUTING -j MASQUERADE insmod ebtables insmod ebtable_filter insmod ebt_pkttype ebtables -A FORWARD -o "eth1" --pkttype-type multicast -j DROP ebtables -A OUTPUT -o "eth1" --pkttype-type multicast -j DROP
under security--> firewall make sure filter multicast and Filter WAN NAT Redirection are NOT checked. after this you should have smooth sailing.
