ReadyNAS Duo DLNA server = crap (or am I wrong?)

I Also own a readynas duo, i had twonky installed and the dlna server, i usually stream media from an xbox 360, i had to wait at least 5 minutes each time for the Readynas duo to be detected in the source list (sometimes it didnt even appear). i have to say i think all slow detecting and dissapearing problems comes from using cheap routers provided by the ISP. i recently bought Linksys E4200-EW Wireless-N 450 Mbit Router Simultan Dual Band and all this problems are gone. now the twonky media server is always there when i see the source list! try testing with other routers, connecting the server directly to try to isolate the problem.
