Hi,

In my home I have a Mikrotik RB951G-2HnD (Webfig v6.27).
I have issues streaming data from a stb to my PC via wifi (~8mb/s).
Images haves pixelation.
Is there any way to fix this issue ?
My stb stays at 5 meters from my router.

What sort of throughput do other wireless clients get? 8Mbps doesn't sound like much. What happens to ping times to your STB when it's streaming?

I don´t have packet loss in ping command when streaming is running:

Estatísticas do Ping para 192.168.88.100:
Pacotes: Enviados = 251, Recebidos = 251, Perdidos = 0 (0% de
perda),
Aproximar um número redondo de vezes em milissegundos:
Mínimo = 1ms, Máximo = 1992ms, Média = 28ms
Control-C
^C

Please look at this post to see more details about this problem:

Thanks.

If the ping time isn't perturbed when you're streaming, then it doesn't sound like you're hitting a limit in the network bandwidth.

Hi,

I did a test , installing a network cable connecting my set top box with Mikrotik router, and images are perfect !

I can´t believe that my Mikrotik RB951G-2HnD router can´t manipulate 16Mbps data by wifi !

Hi,
seems that you have issues with your Wi-Fi settings, but it's quite hard to help you with data you gave us.
Can you connect using winbox (or ssh), run following commands in "new terminal" and paste results here?

This will print all your configuration hiding sensitive data (like passwords, WPA key ecc)
#1: /export hide-sensitive

Then during your issue:
#2: /interface wireless registration-table print
The above command will print the registration table which contains data about current associated clients

Once you provide info above I'll be able to help you further.

I streamed HD video from my external HDD via WiFi without problems. Im distanced from router ~20m with many walls between router and me. However, WiFi is not recomended in any way to stream too much data. If you want performances, and stability only cable is the answer.

Is there any config changes that I could apply in my router to improve it ?

I did that changes in my router like yours, but unfortunately I continue with that issue...

Hi valdemirs,

Is that simple queue targeting your set top box?
If yes that would be the issue since the default queue configuration is not enough for media streaming, therefore please try to disable it and let me know

Hi,

I remove that queue from the router´s config , with no success. I have a lot of pixelation in images yet.

I´ll buy this device to try solve this issue:

Thanks.

valdemirs,
that's really strange I have AP installations which support around 100mbit over Wi-fi.

Did you try changing frequency?

Try to download Btest from Mikrotik download page and run a TCP test to ensure that issue is outside our wireless config.

I changed frequencies in my Mikrotik router, but with no success.

I think that I have a lot of interference here,

Issuing a Scan I find 114 networks around me.

I downloaded btest, but which IP address need I put in the tool ? My Set top box Ip ?

valdemirs,
Interferences can be a problem but if signal is very low (below -90dbm) it's not a big deal, if it's strong (above -90dbm) then you need to avoid at least 3 frequencies around it.
If we will not able to find any suitable channel then we need to change the band (e.g. move to 5Ghz), change AP location or find the channel with lowest possible interference, unfortunately 801.11b/g/n has only 3 non overlapping frequencies and if all of them are busy then we are without solutions.

About btest you need to put your Mikrotik IP there, it's actually the PC version of the bandwidth test that you can find inside the RouterBOARD.
You need to disable all networking related software on your PC and then run the test, based on the results we will know where the problem is and how to fix it.

How save data to show you ?

valdemirs,
from the output you sent me your router is able to create a total throughput of ~ 80Mbit (53Mbit towards your laptop and 26Mbit from your laptop to your router) therefore the wireless configuration is ok.

Now question is how the stb communicate with your PC?
if it uses wireless you will have the root cause of your issue because Wi-fi is not full-duplex.

Solutions:
#1: run a cable between your stb and RouterBOARD and use wifi only to communicate to laptop
#2: install another radio (if the RouterBOARD permits it) and use one radio to communicate to stb and the other to the laptop

Hi Matteo,

I just want to tell you that the first btest test was made by my PC (connected to Mikrotik router by network cable).
Screenshot below is the btest test issued from my notebook (connected to Mikrotik router by wireless).

Thanks

valdemirs i tested the speed from my laptop via wifi to my Mikrotik and i get the similar results like yours. 23/7 mbps, so i think that wireless connection is not the real problem.

Can I install a 5ghz USB transmitter like this (below) in the Mikrotik´s USB connector ?


http://www.dx.com/p/cheerlink-ultra-fas ... UGBZZtdXUY

Short answer is 'no'. Long answer is, maybe if it is Atheros chipset, but there aren't any 5GHz USB adaptors on the compatibility list, so no.

Hi,

I just want to tell you that I´m using this device:

And now I get perfect images !!

Thanks

This host looks bad - it also appears to be running an 802.11b bitrate. . .
If any host is using B then it really screws up the whole sector...
Try G/n only.

looks like you are using this tplink device as a repeater

thats the cause of the problem
