I have a problem streaming FUll HD movies via WiFi maybe you can help me to debug this.
If I stream this via wired connection the movie is played quite ok.
The wired config is like this:
laptop (gigabit wired) ---Routerboard RB250GS managed Gigabit 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/Android phone/Iphone4 (same movie) (wifi connection) --- same 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 following pic) - my AP is on channel 10 http://img502.imageshack.us/img502/4447/crowdwifi.
- the router ?
- TV Ethernet port
- or something else ?
Any idea how do debug this ?
By the way the Full HD movie has 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)
