Linux/WL1831MOD: Bad WiFi performance

Part Number: WL1831MOD
Other Parts Discussed in Thread: AM3354

Tool/software: Linux

Hi,

I am using R8.5 with Linux kernel 3.14.49 (Arago distribution, daisy branch).

When running iperf for UDP, I was getting below results:

root@am335x-evm:~# ./iperf -s -B 192.168.43.116 -i1 -u

As you can see, it is not acceptable to have such performance.

Then I created a new wl18xx-conf.bin using configure-device.sh, which gave me slightly better results in term of less drop percentage but throughput is still bad

We have single 2.4GHz antenna on board.

My question is how can I improve the WiFi performance ?

Please don't suggest update to R8.6 as I can't because of various reasons. I am pretty sure R8.5 is not that bad and many users are still using it.

Regards

    To add more info, if I use hotspot functionality of the module, then I get far better results:

    Ankur ,
    Are you running your tests in controlled environment / RF chamber or open air ? Multiple factors can effect throughput - air traffic , RF performance of Device under test , Host speed etc. What Host are you using ? Did you do RF characterization on your product ?

    Thanks

    Hi Saurabh,

    I am doing these tests in open air and I understand multiple factors can be affecting the performance.

    But I have made sure using WiFi analyser that open air environment is not that hostile to have such poor results. It is much more closer to normal home/office environment with few AP's in range.

    I am running iperf server on an AM3354 based product running at 800MHz with Linux kernel 3.14.49

    I didn't do any RF characterization on product, can you please tell me what to do and how to do ? And I will share results

    thanks

    Hi Saurabh,

    Did you find anything wrong in the wl18xx-conf.bin dump ?

    Hi Ankur,

    Since you are using a very old version of WiLink8 driver , some differences in wlconf dump are expected . I noticed trace loss and other values ( picked from INI ) are different . I am assuming you are using TI module and matching INI - correct ? I know you don't want to update to latest driver , but it is highly recommended . Regardless you need to ensure RF on your board is ok - you may consult following PLT tests to check if radio is working as expected : http://processors.wiki.ti.com/index.php/WL18xx_TX_Testing
