Hi,

Currently I have an ordinary (not managed) D-Link Gigabit switch (small for home - 5 ports) but for some reason is not capable to handle Full HD streaming. Tough is labeled as gigabit switch so in theory it should handle it without any issue but it doesn't.
The streamed movie is played with interruptions.

For instant I have a Full HD movie with the following specs:
- Video (1920x1080p Data rate 13619kbps, Total bitrate 13680kbps, Frame rate 23 frames/secons)
- Audio (Bit rate 61kbps , 1 channel, 44Khz audio sample)

Is RB250GS capable to handle streaming like this ?

any switch can stream a hd, you have another problem

I'm streaming from a laptop (Gigabit Ethernet port) --- > Gigabit switch ---> TV (Ethernet port) , the laptop and TV are getting their IP from a router with 100Mbps ports - where do you think the problem might be ?
If I stream HD (720p) everything is fine ... there are no interruptions.

I am streaming, a full hd 1080p from a laptop (gigabit) -> gigabit switch (RB250GS) -> rb433 wifi bridge 802.11n -> rb433 -> TV (ethernet)
everything works fine! the switch is not you problem!

Ok then, any clue what the issue might be ?

Ok for those who told me that 'something else is the problem' without telling what ...
I've replaced the switch today with RB250GS and the problem went away ... playing the exact same movie for 5 minutes was played fine with just a few interruptions where with previous switch I got interruptions every 5 seconds ...

The config is now like this:
laptop (gigabit wired) ---RB250GS switch ---- Buffalo WZR-HP-G300NH DD-WRT router (Gigabit ports) --- TV (wired)

So the 5 minutes FULL HD movie was streamed with very little interruptions.

Now the issue is playing the same movie via wifi :

laptop/phone (wifi connection) --- DD-WRT (router) (wifi 802.11n with HT20 or HT40) --- TV (wired)

The movie is played with interruptions, plays fine for a minute or so, then is played with interruptions every 3 seconds (like is buffering or something or I don't know) .

I was wondering what the issue is:
- the crowd APs from my area (please see the attached pic) - AP is on channel 10
- the router ? (if so, I was wondering if a Routerboard WiFi router will do better ?)

Any idea how do debug this ?

offtopic: what's the program that makes that nice graph?

Another good one is WiFi Analyzer on Android

Give as much info as you can, or it is very hard to help you, perhaps you should also write to mikrotik as normis mentioned, perhaps they could diagnose that much better than we customers can do
