i appreciate your help. all the settings u had is rly bad on me. with that kind of settings on my router it probably will drop within a couple minutes of youtube streaming. there are so many mixed results within rt-n56u owners out there. may i know which version u r running though? i always have the full version instead of micro, because i use transmission and media server almost 24/7. one user named 'Flak' did mention about the full version never worked so well for him/her and installed micro version instead.
I build my own firmware so I can cut out the features I don't need (IPTV, IPV6, Media server etc). If you are interested in doing so yourself use the following guide.
