[QUOTE="Lotsofjazz, post: 361346, member: 64243"] Dear all, Since a week I have a network attached storage device, Revoltec Alu Guard LAN with 1500Gb harddisk (XFS formatted, whatever that is, the only way to get full access and large file storage capability over the network). I have attached it to my Modem/router (Fritzbox 7170 Wlan fon) using the RJ45 Lan port, the main HTPC is connected using wireless lan 54G++ using a FritzStick at the HTPC side (should be capable of 125Mbit/sec, better then 10 base 100 wired LAN). I tried to play a HD movie yesterday from the Revoltec, but that doesnt work as I expected, checked with shift-1: A lot of stutter and jitter, framerate of about zero, couple thousand jitter, hundreds of dropped frames. I checked the wireless connection while "playing" the movie and found out traffic was about 6 to 8MB/sec, while throughput was 54MB/sec.. Throughput is allways at 54 even with no network activity, so it seems the WLAN capability is not fully used at all. Playing the movie at the HTPC itself it plays smooth, so it must be the network settings. Anybody here who has a working 54G (or 54G++ at 125Mb/s) Wlan working with HD movies? and if so, what are your settings at the router side and HTPC side? Any advise or tips are appreciated. Thanks! Lots UPDATE: I did some up and download testing.. First I cant get it to screem at 125 Mbit a second, however the monitor says it is at its max, which is 54Mbit/sec.. but also the windows network monitor just sees 54Mbit/sec.... I tried to use the same file just downloading, and then it goes much faster, somewhere around 20Mbit/sec while I was downloading something from the internet the same time. doing an upload, the download speed decreases to somewhere around 10 to 15 and is not so constant anymore, it goes up and down between 10 and 20. None the less it is much higher then what I saw during playing the HD movie (MKV btw). So my conclusion is that the network bandwidth/speed is actually more then adequate but there is something not right at the receiving end or the player (mediaportal?), like a buffer is not large enough or something. I have looked everywhere, but everything seems to be at its max for WLAN. So if anybody knows where to look. Any help is appreciated. Thanks. Another Update: Now I tested with a DVD rip (the usual DVD format with VIDEO TS directory and a couple of IFO, VOB files and such) Works perfectly!! Watching the Fritzlan stick monitor, it shows that there must be some kind of buffer because it goes up and down all the time from zero to sometimes 18Mbit/sec.. looks like a sharp sinus curve. So question is why doesnt it work this way with other formats.. I guess the WMM is doing its job here. I will try with some Windows Media HD Video's tomorrow, I think that should work as well beacause these are also managed by the WMM is my guess.. but we will see. [/QUOTE]
