Lags over wifi

[geostant]

I'm streaming over my wifi at home, it's a N connection (150mb)
to my xbox at the living room.

The files are MKV 720p with external subtitle files (probably transcoding ?)

I've a pretty strong computer :
i7-3820
16GB Ram
Windows is sitting on SSD drive
and GTX580 or maybe 570...

Still, the video starts to run,
it goes smooth for approx 10 seconds and than start to lag and freeze frequently
like it buffering again and again.

My wifi coverage at my PC is at max,
a software called INSSIDER for wifi analyzing says that I'm all well with my wifi connection.

I tried to decrease the quality of the video stream (media device > xbox 360 > video bitrate) all the way to the minimum and the video sure looks very bad but it still lag.


Suggestions ?
I would love to wire my connection but it's impossible as it's a rented house and the living room is on the other side of the house.


Thanks

Try using powerline plugs instead as I was having a similar problem with my Wifi and it solved the problem. Make sure they are suitable for HD streaming.

Actually I did
I got D-Link powerline AV 500
but the power lines of this house are pretty bad
I had only 35mb connection and was worse than the wifi

I don't have another outlets to swap with and I had to go thru a power split as the TV and the XBOX need power too :(

If you have a dual band router, then try using the 5GHz band rather than the 2.4GHz band. The 5GHz band may provide better streaming performance and have less interference from other devices in your home. Many Mezzmo users have reported better wireless streaming performance when using the 5GHz band. Consult your router's and devices' documentation for the recommended 5GHz configuration.

Also, when streaming a video and it's stuttering/freezing, go to Mezzmo and check the Transcoding pane. If you see your video listed there and marked in red, then the reason for the stuttering is transcoding on-the-fly is too slow. You should pre-transcode your video first and then stream it. That may fix the stuttering.

I've done extensive testing with streaming over Wi-Fi. I agree that moving to the 5GHz band will help. I am able to stream reliably up to about 25Mbs with most normal Wi-FI N band adapters in the 5GHz band. Beyond that I had to go to an HD optimized wireless device which had large buffers and minimal jitter. The Netgear WNCE4004 is the only device I have found where I can stream full Blu-Ray (40Mbs) speeds with no drops. With the WNCE4004 I am able to run a full 100Mbs file copy job, while streaming a video with Mezzmo above 30Mbs. I did that s a stress test just to prove how much buffering and throughput it has. I use a WNCE-4004 daily and never have any dropouts.

Excellent information as usual, jbinkley60. Thanks for sharing it.

hi,

one month ago I start have lags to. I didn't changed NOTHING anywhere, but now sometimes I get lags. I can't found solution yet, because, one day I can't watch movies, second day the same movie works without problem. My wifi works on 300 Mbps.

P.S. of course, I testing only transcoded files!

The next time your video lags/stutters, go to your PC and check the Transcoding pane in Mezzmo. If you video is listed there and is marked in red, then transcoding is too slow for real-time playback. In this case, you should pre-transcode your video before streaming it (see http://forum.conceiva.com/showthread.php/6025-Tutorial-Pre-transcoding-Files). If it is not marked red, then check the performance of your wireless network. It is likely that your signal strength is not optimal or other devices are interfering with wireless between your PC and DLNA device(s). See this FAQ for other possible reasons for stuttering - http://forum.conceiva.com/showthread.php/6538-Tutorial-How-to-reduce-excessive-stuttering-or-buffering-when-streaming-videos.

Paul, I wrote, what I testing with transcoded files! Signal strenght like always was, not maximum, it's in middle. But two, three month ago everuthing worked.

Sorry for the misunderstanding. It's best we see a set of logs. Turn on logging (see http://forum.conceiva.com/showthread.php/419-FAQ-How-to-turn-on-diagnostic-logging) and restart your Mezzmo server. Reproduce the stuttering problem on your DLNA device and then stop your Mezzmo server and exit Mezzmo. Zip up all the logs and email them to us at support [at] conceiva [dot] com. Also in your email, include the FFmpeg information for the already transcoded file. To get this, right-click on the video and click 'Properties'. On the Properties dialog, go to the Transcoding tab and select the transcoded file and click 'Get FFmpeg information'.

I found a problem, that was not mezzmo problem. I just moved my router to room whre is baby camera, which works in 2.4 GZ like my router. When camera works, sometimes (not always) cameras frequency cross with router frequency, then movie start lag. Just need to turn-off camera, and that's all.
