Message-ID: <CAOQ4uxi1+yUAkqriUhKMMgnjLvBN1xW7RwpO+h8E1+MesfkFkQ@mail.gmail.com> Date: Thu, 24 Nov 2011 12:24:36 +0200 From: Amir Goldstein <amir73il@...il.com> To: "Alex Van't Hof" <alexvh@...columbia.edu> Cc: Ext4 Developers List <linux-ext4@...r.kernel.org> Subject: wifi issues workaround Hi Alex, After 2 days of no wifi issues on my beta device, Ziv has configured a gmail account on my device and that has changes everything. >From that point, like QA has repeatedly reported, device has woke up from sleep mode in endless scanning... or obtaining IP.. states and to get out of this loop required either: 1. switch persona 2. connect USB 3. enable/disable wifi I concluded that the issue was created by gmail changing the default wifi sleep policy and verified that by applying a workaround - setting wifi sleep policy on both personas to never. Since I did that (and Ziv too), I have no more wifi issues. I've instructed Dror to resolve the "agent always connected" issue by taking a wifilock on both personas and that should also resolve the wifi connectivity issues. The remaining question is: Given that your wifi sharing code doesn't work well when the 2 personas are using a different "state machine" (i.e. never sleep or sleep when screen is off), do you see any clear and immediate bug in your code that should be fixed as well? Thanks, Amir. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
