Important: Solution Wi-Fi problems, which with some SIM cards refuses to connect to the access points in the 802.11n standard and 5GHz frequency.

Due to an error in translation, Wi-fi settings in "Do not disconnect from the wi-fi in sleep mode" is recommended to use the "Always".

In my experience:
As for "always" and "never."

In "Always" Wi Fi is constantly active. When I get to the house, the body in sleep mode connect to my point automatically. Connection occurs even if I had previously been in the 3G internet mode.

In the "Never" after locking Wi Fi phone still works for some time (about 15 minutes after falling asleep). Only then Wi Fi is turned off. Apparently this is done in order to avoid constant on / off Wi Fi during a short sleep. If the device is in the mobile Internet, he turns instead of Wi Fi after 15 minutes of waiting in the sleep mode.

Many of us have to solve certain problems with the power on the phone. Despite claims by some users that the wifi does not affect the phone's power consumption, I can say with confidence that the wifi module really much spending our battery. The phone's settings tab has a "Wifi", press the left soft key, turn on the "Advanced" tab, then under "do not disconnect from wifi" select "never". (Some firmware must be selected "always") After selecting the item, the wifi module will be switched off automatically 15 minutes after switching the phone to sleep mode. However, some applications do not give the phone from going to sleep, and therefore enabled wifi module clock. These programs include "OpenID", "Classmates", "Mail" (Mail), "Viber", etc. To be able to transfer the phone to sleep mode you need to enter in the settings and remove the check mark in paragraphs notification. In particular, in paragraphs "Push-notification", "Manner", "alert", "Wifi - policies standby", etc. Do not declare that discovered America, a lot about it and so know, but when faced the problem in the search for applications that do not allow to go into sleep mode wifi module, no one could help me.

For those who have problems with wi-fi on firmware 4.1.2

This question has acquired this unit with it, as it turned out later, not Robit wafer. I have made a custom request, such as the start, connected to the network, normally a couple of minutes and off. Although the wi-fi works, sees the network and connect can not until you turn off and turn it, and then all over again. There are suspicions in the module was replaced for a bunch of firmware, various fixes applied. Who has any ideas? Already nerves not enough .. And just maybe an hour to work out, or may immediately shut down.

Maybe someone will come in handy.
On tefone sgs3, in the latest official firmware, does not want to see the 14 wifi channel.
I tried everything - I was recording in build.prop, changed com.android.providers.settings / settings.db
Nothing helped. The channel is empty, do not see anything.

Helped edit the file /system/etc/wifi/nvram_net.txt
The line "ccode =" put the value of JP

Reserve, turn off, turn on wifi.
14 channel appears.

Tell me what it means to "Sign-in required" appears in the list of wifi networks is on my access point? When connected, is connected, then the login window will appear prompting you to select a browser. I'm canceling because just open the browser. After that wifi works a few minutes after going off from the access point and then 'Sign-in required ". So it can be repeated many times, until you get bored. Previously, this was not happened suddenly. Another tablet android 4.4 works fine with this point and the other device with wifi.

Interesting problem was, it seemed that with Wi-Fi
Nullify an old smartphone to firmware 4.1.2, insert a SIM card has not yet managed. But I managed to replace the files in the folder, and even started to think about resoldering chip ...
But it was guilty obnovlyalka firmware! because of it, when you turn on Wi-Fi and the advent of the Internet, smart phone would start reloading, and it happens to turn off the Wi-Fi!
If you stop the Update (stupidly regular means), the smart phone for a long time working with the Internet. However, after some time (maybe one day), this stuff is restarted and reset continuing): NeRutovy firewall does not help ...
