Wifi has not been connected to userspace on the snowball. Wifi has not been tested yet on the july-ALK3.0 and On V3 boards, this is not possible because of a HW problem.

[Mathieu Poirier (mathieu.poirier-deactivatedaccount)]

Setting target for 11.11 since V5 boards should arrive soon.

Same issue is observed with iMX53 Hardware(Rev G) with build:

Logcat message says: Wifi driver loading failed.

Issue still observed on Snowball Hw(V5) in build:
https://android-build.linaro.org/builds/~linaro-android/staging-snowball-11.10-release/
build 1

Updating Bug thread to have latest info on this bug.

[Bernhard Rosenkraenzer (berolinux)]

iMX53 doesn't have wlan hardware, so this is expected - unless you're using a USB wlan stick or something (which we AFAIK don't support for now)

[Fathi Boudra (fboudra)]

Set the bug to invalid for FSL LT as i.MX53 doesn't have wlan.
@Abhishek: QA test should be set to N/A for the boards that doesn't have the hardware out of the box.

"WiFI settings" UI option is not available under Settings->Wireless and networks in ICS release:
https://android-build.linaro.org/builds/~linaro-android/staging-snowball-11.12-release/#build=1

[Abhishek Paliwal (abhishek-paliwal)]

WiFI still not working on Snowball ICS releases, tested on:
https://android-build.linaro.org/builds/~linaro-android/staging-snowball/#build=90

[Patrik Ryd (patrik-ryd)]

Still valid for https://android-build.linaro.org/builds/~linaro-android/staging-snowball-11.12-release/#build=4

Not possible to enable wifi in settings menu.

[Riku Voipio (riku-voipio)]

Wifi sees my networks but with poor signal quality, and is unable to associate. perhaps an antenna is needed?

Chances are it is the antenna. You are talking about Ubuntu.. not
Android ... right?

Linaro Android tree (stable-android-ux500-3.0-mali-v9) is not in sync with igloo's tree (stable-ubuntu-ux500-3.0). Some critical patches, which detect wlan/bt chip revision and do platform initialization are missing.

[Mathieu Poirier (mathieu.poirier-deactivatedaccount)]

This is interesting Amit. The androidization process was hard on the BT code and I wouldn't be surprised that some got munged in the process. I you find missing patches apply them - otherwise I'll look into it upon my return.

[Amit Pundir (pundiramit)]

I have got WiFi working from command line on ICS using wireless-tools but I don't have a mini-A USB adapter so can't test/fix it from UI.

[Amit Pundir (pundiramit)]

Now got WiFi working on ICS from command line through wpa_supplicant.

It is a bit tricky. Android makes use of SIOCSIWPRIV private ioctls which are not implemented by cw1200 driver. So, I'm not using wpa_supplicant_8 that got shipped with ICS.

There is a workaround available for wpa_supplicant_6 shipped with Gingerbread which implements these private ioctls locally https://gitorious.org/picopc-android-gingerbread/external-wpa_supplicant_6/commit/5f5c50d722eedaedd75c1698b79f464310ce6478?format=patch. I tested that and it works fine for us. For the time being we can stick to this until we patch wpa_supplicant_8 with private ioctl support.

[Amit Pundir (pundiramit)]

Got WiFi working on ICS from GUI.

It is not a release material yet. Still got some major issues:
1. hciattach which fails to power up BT/WLAN chip like 3/5 times.
2. Wireless settings Activity/Window is missing. It doesn't come up. logcat shows some gles(mali) failures while rendering Settings window.
3. Frequent connection drops. Which could probably be because of Station Antenna or AP issues.

[Anmar Oueja (anmar)]

igloocommunity-maintainers team: Anybody can help Amit P. fix up his issues in comment #23?

[Amit Pundir (pundiramit)]

http://review.android.git.linaro.org/#change,1378

wlan/bt drivers fail to power-up the chip sometimes(1/5 times roughly), so we can't enable wlan in that case. We can take that up in the form of another bug.

Also I see frequent re-connections happening at my end (because of poor connection status in ICS, though router is just next to the board) but that may also happening because I don't have antenna attached to snowball as Mathieu pointed out to me once.

[Amit Pundir (pundiramit)]

Marking this bug closed/fixed, since we integrated wlan in landing-snowball which solves this particular bug.

There is one major bug left in wlan bringup on ICS but that I'm going to take up separately here https://bugs.launchpad.net/linaro-android/+bug/918643

[Anmar Oueja (anmar)]

Mathieu: Please test in the 2012.01 rc build and update the bug accordingly.

[Paul Larson (pwlars)]

I don't think this is really valid in ubuntu, or at least not any more? I have wireless enabled by default with snowball on ubuntu, though there are other issues with it, it can be made to work. please reopen if there's something I'm missing here
