Android wifi function can not pass netperf test

[charleshuang]

Target O/S: Android

Target Software Package: android_jb4.2.2_1.0.0

Wifi module: intel 4965AGN

We use netperf to measure the performance of wifi function.

And set 500 times continuously and interval of 10 seconds each,but every time it fails

According to test log, the error always occurred while measuring TCP transmission

Could you help to solve this issue?

hi Daniel,

Can you please provide Android log(adb logcat -v time) and kernel log during netpert TCP testing? The attached netperf log only shows TCP/UDP test result, no help to find the cause. Thanks.

hi Charles,

I get no useful information from the log. I think the problem might be related with the configuration of INTEL WiFi driver, like power saving mode. Would you look for the support from INTEL?

I can dig into INTEL driver but I need the environment. Can I know if this module can use in i.MX6 SabreSD? If so, can you lend me the module and the related source code? Thanks,

Regards,

Max
