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

so do not write speed. it is not clear that it is the bytes or bits.

This is exactly the bits as you may guess. If Speediest on the wafer showed 50MB / s, I'm not looking at your wire on a wafer vary.
And yet, yes, this is clearly 802.11n, because, as noted correctlydima8389 in this case the question is not about connection speed and data transfer speed, since the measurement is made using SpeedTest and 802.11g longer 22-25 Mb / s will not pass overhead on large overhead and error correction

Be kind enough to install from the Market (free) programku WiFi Analyzer, there select the tab "the AP list" and place a screenshot pliz. We'll see at what frequency the phone is connected.
Well, just the same, if possible, a screenshot with the speed of runoff WiFi settings.

I do not believe that the phone can be different!

Absolutely right in the hole !!! And while all are silent about the speed of incoming traffic from the provider ...))))) And there is not always the speed of which they claim. And then the whole discussion is direct divorced. I understand discuss operating speed via GSM channel. And then-then what to discuss? Each has its own speed provider. Each router is a limit speed. We're about the firmware SGS III or talking about surfing speeds via Wi-Fi ?????

Tell me honestly, are you so often exchange large files with your household and the provider of the server name to the handheld? file size of 1 GB, even on the standard G shaken for 5 minutes, for any problems to be solved on the PDA, this is not enough ???? I do not understand...

What a stupid assaults? Speed ​​is necessary in the first place because sometimes we have to shift data from a home computer, and too lazy to stick wires and secondly because this mode works with all the other cheaper devaysa and would have on such an expensive toy to work.

And in my opinion this is outright rudeness. The problem is clearly widespread, and it is associated with SGS 3, for exactly the same hands, all other devices in N mode work. So I would ask the filter market.

Also as there are different. The manufacturer is not obliged to do absolutely all phones are the same and depending on the situation without warning can collect them from a variety of components. Open at least a branch chambers, where there is information about two completely different camera modules installed in sgs3 without any dependence.
And specifically on the Wi-Fi I lpisal in discussing a long time ago that I personally endured nandroid backup sgs3 from one to another, exactly the same, with the same firmware and other things. Thereafter vayfay was constantly losing signal. And in what he did not take a backup from another sgs3 - everything works and vayfay not. We had to do a reset and customize the new one.

IP TV, movies with networked storage, torrent. Ftp server from the phone. That's what. Sin to use such power only to send text messages and photos. I personally have long ago moved to the N, and I do not like that the phone does not work correctly in this range. So discussion of this issue is overdue. A long supported providers such rate, at least in our city (Krasnoyarsk).

pANd4, Thanks for the screenshots!
But it is clear that the compound is at 5GHz.
And it is possible to convert the router to 2.4GHz and have the same operation?
I would argue that in the 2.4 GHz band has N rises.

Well, why not? I have a router dir-300 only supports 2.4 GHz but the phone with firmware runs LFB c it perfectly.

Exposure withWikipedia:

... The frequency range and operating restrictions vary across countries. In many European countries are allowed two additional channels, which are banned in the United States; In Japan, there is another channel in the top of the range, while other countries, such as Spain, prohibit the use of low-frequency channel. Moreover, some countries, such as Russia, Belarus and Italy, require the registration of all Wi-Fi networks, working outdoors, or require registration of Wi-Fi-operator.

Not your case?

pANd4, Thank you for the screenshots.
I sprinkle my head with ashes.
Now certainly I can not understand anything. To my DIR-615 access point (2.4GHz only) to connect to the N range GALAXY NOTE and laptop without problems.
A SGS III only G, in the N range is simply not connected. Although the network sees.

How to check, WiFi module is a cost? There are some prog?

Probably really need to create a thread for WiFi.

about wifi / N and LFB
those who say that they have such a bunch of work, you do not stock the core, right?
if there is a stock kernel and csc LFB LFB is no wifi / N will not, it is such a "feature" of the firmware
and run to change the phone is not necessary, it is not a marriage, and the router also does not need to break, you just need to wait for a new firmware :)
