Wifi does not always work on Samsung Origen

[Zach Pfeffer]

I booted up
https://android-build.linaro.org/builds/~linaro-android/origen-ics-gcc46-samsunglt-stable-blob-12.02-release/#build=1
3 times.
I enabled WiFi each time.
It only worked the 3rd time.

[Chengjie HE (chengjie-he)]

I talked with Sangwook on this, here is some update:
1) for origen board, there are two versions, the chipset of ath6kl differs on the two versions. I use the new version, so it will use "hw 2.1.1 fw 3.1.1.609" as its firmware, so could you check which firmware your chipset uses? If you still use the old version of board, I am not sure I am debugging the same issue as yours.
2) here for my board, sometimes you can turn on the wifi, sometimes you can't. Is this the same bug as to your board?

[vishal (vishalbhoj)]

The wifi is not stable on origen build:
https://android-build.linaro.org/builds/~linaro-android/origen-ics-gcc46-samsunglt-stable-blob-12.03-release/#build=5 . works some time and sometimes when we turn on wifi from GUI we see this kernel messges:

[Alexander Sack (asac)]

this should have been forwarded to the origen LT, no?

[Sangwook Lee (sangwook)]

OK, please let me produce this problem and then will update.

[Sangwook Lee (sangwook)]

Turn on/off WLAN looks like:
Turn on WLAN => $ insmod /system/modules/ath6kl.ko
Turn off WLAN => $ rmmod ath6kl

If I repeat the following in adb console,
 $ insmod /system/modules/ath6kl.ko
 & rmmod ath6kl
mostly it works fine.

If I turn off/on WLAN UI, it makes errors:

For example
<4>mmc2: queuing unknown CIS tuple 0x01 (3 bytes)
mmc2: queuing unknown CIS tuple 0x01 (3 bytes)
<4>mmc2: queuing unknown CIS tuple 0x1a (5 bytes)
mmc2: queuing unknown CIS tuple 0x1a (5 bytes)

<6>mmc2: new high speed SDIO card at address 0001
mmc2: new high speed SDIO card at address 0001
<6>mmc2: card 0001 removed
mmc2: card 0001 removed

Last two lines are quite strange
As soon as WLAN is turned on from UI, I guess it doesn't wait till driver is loaded
and then return error. How about the waiting condition till loading driver in platform code ?

Hmm.. let me see more others.

Please ignore the below.
This is a packet error, being flushed out.
ath6kl: tx error, status: 0xffffff83

[Sangwook Lee (sangwook)]

@vishal

I downloaded today's version android ( 28 March 2012) And after building image, I turned on/of UI again.
It seems to works fine. At first glance, there seems to be an blocking mechanism to prievent turning off suddenly
during turning-on process. Please try it with the latest version Linaro Android, let us see it again.

[Chengjie HE (chengjie-he)]

added some delay in HAL to let the module be loaded successfully

[vishal (vishalbhoj)]

Jackh,

Can you point out the change you did ?

Sangwook,

I tried https://android-build.linaro.org/builds/~linaro-android/origen-ics-gcc46-samsunglt-stable-blob/#build=238 . I found that it happens when we turnoff and turn on the wifi quickly . This is a corner case,but once this happens we need to reboot the board to have wifi working.

[Chengjie HE (chengjie-he)]

only one line of code change:

On build:

https://android-build.linaro.org/builds/~linaro-android/origen-ics-gcc47-samsunglt-stable-blob-12.04-release/#build=2

DNS can't be set automatically, thus, the board can't access Internet except manually set DNS server.

Also, the WiFi enabling was failed at the first time, but succeeded after several tries. It means the WiFi enabling doesn't not always work, as this bug title described.

[Zach Pfeffer (pfefferz)]

Based on Botao's description this is still inprogress.

[Zach Pfeffer (pfefferz)]

Moving it off the schedule due to 12.05 priorities and current resource levels.

DNS can't be set up automatically after WiFi connected.

[Sangwook Lee (sangwook)]

@Chenglie, others?

I can see this issue with android tracking branch. DNS is not set up automatically .
Do you have any idea ?

I think what the reporter said is the enable fail bug still exists there.

[Sangwook Lee (sangwook)]

SUMMARY:
In this bug reports, there were two issues:

1) When turning off/ on quickly
  The patch was added in Android platform source code by Chengjie.
  Simple this is to prevent user from pressing quickly untill WLAN is completely loaded.
  This issues has no relation to run-time operation.

2) DNS issues.
 Android platform code have to try DNS setting properly once WLAN is connected to Access Point.

[Botao (botao-sun)]

For Origen, works well on build:

https://android-build.linaro.org/builds/~linaro-android/origen-hangout-demo-12.05-release/#build=1

[Botao (botao-sun)]

For Origen 12.05 release build:

https://android-build.linaro.org/builds/~linaro-android/origen-ics-gcc47-samsunglt-stable-blob-12.05-release/#build=6

The DNS still need to be set manually.

[Annamalai Lakshmanan (annamalai-lakshmanan)]

Hi Sangwook,

Could the DNS setting be automated in Android, So User can be free from setting Config,

Botao,

Your comments on this.

[Sangwook Lee (sangwook)]

@Annamalai
Please look into Android stack related to DNS or DHCP. Android platform must take initiate these connection. It might be related to init xx.rc file or somewhere.

[Annamalai Lakshmanan (annamalai-lakshmanan)]

OK, Thanks!, Shall compare the 1202 Origen Hangout and 1205 to see the init.rc changes, probably something is missing there..

[Botao (botao-sun)]

DNS still need to be manually set on 12.06 RC1 build:

https://android-build.linaro.org/builds/~linaro-android/origen-ics-gcc47-samsunglt-stable-blob-12.06-release/#build=1

[Fathi Boudra (fboudra)]

Closing the initial issue: wifi doesn't always work on Origen.
Separate issue created to track the DNS problem:
