Wifi Keeps Dropping - Galaxy S III Q&A, Help & Troubleshooting

Connected to home network, I keep the wifi on my S3 on all the time and it seems to be connected (from the icon in the top bar) but there is no data connectivity.
I have to manually switch wifi off then back on for the internet connection to start working again. This is the case after waking the phone up, and also just when the wifi has been on for longer than a few minutes even when the phone is in use.
Keep Wifi on during sleep is set to ALWAYS.
Does anyone know if this is a common s3 problem or is it specific to my device, and are there any fixes?
Thank you.

WiFi issue on my Hero...

Hello everybody!
Someone of you has noticed a poor WiFi reception on Hero?
I'm experiencing a poor WiFi reception in my house when Hero is connect to internet thru an access point.
What happen is that after WiFi connection has been established the phone tends to loose it and restart connection thru GSM/3G link.
That happen also if phone stay in the same place without moving around and also when phone is close to access point location.
Any idea about way to solve the problem?
Regards.

Just an upgrade on issue...
If I turn off data connection thru GSM/3G and switch on WiFi seem that WiFi connection is stable so maybe issue come when both data connection are enabled...
Anyway is annoying shout down each time data connection on GSM/3D and power on WiFi!
Regards.
i believe wifi goes idle when not in use. so it connect to 3g or edge. However there is an app if not various in the market already to help keep wifi always on..
Do a search for wifi and see for yourself.

Thanks for suggestion!
At now I've solved turning off GSM/3G data connection when I'm at home anyway I guess that WiFi reception sometimes go away due to issue of the phone or maybe as way to save battery...
when that happen phone stay unconnected so I guess that should be better if I will check for apps that keep WiFi connection always working!

when the device goes into standby, the wifi is turned off to save battery poweer, and it will go back to 3G.
go into the wifi settings, press menu and select advanced.
select the timeout options
set to never and it will not turn off when in standby.
problem solved and you shouldn't have to turn off Mobile data, although with the settings widget on your homescreen turning mobile data off off each time is hardly going to ruin your life. in fact i tend to do this anyway, just cos i have spent too many years with windows mobile....
Here's an annoying bug I've found tho - on TMob UK
If I send an MMS from home, wifi on, it sits there, and doesn't send the message. Until I turn off wifi and 3G kicks in again.
Now I know for a fact that on my Magic, it was able to turn on 3g/HSPDA to send the message all by itself. Might have a look in thodse advanced settings tho to see if there is something I can do.. Not a biggie, just a bit of an annoyance.

I too, have been doing a search on Forums all over Google looking for a resolution to this.
I have noticed if Wi-Fi is enabled I am unable to send or receive MMS messages.
It is an annoyance having to turn Wi-Fi off each time also I am never to know if someone has tried to send a message in the first place.
Currently using T-Mobile G2 (rooted with MCR Rom 2.8) on T-Mobile UK

Wifi switching itself off

HI all i have a G2 Touch unlocked running Modaco's latest rom and i cannot get the wifi to stay on longer than about 5 seconds. It does search and find networks and i have managed to put in the key for my orange box but in settings/wireless controls/wifi the box stays ticked and underneath the words WIFI it says disconnected. Ive gone to advanced and told it to never switch from wifi and this is remembered but as i said it lasts all of 5 seconds then disconnects and i have only once seen the wifi icon in the task bar once for 5 secs then it went !! Any advice would be much appreciated thanks.
Maybe the signal's too weak and it looses connection?
No it doenst actually ever connect, the wifi program on the phone cuts out way before it ever finds a connection.
Just making sure you've done this:
Go to Settings -> Wireless Settings -> Wi-Fi settings -> Add WiFi network. Then enter the SSID and necessary security information. After all that turn WI-FI on
Thats what i do still just cuts off after maybe 5 secs !! I give up looks like i have a Hero that doesnt like wifi
Hmm, it seems that I had a similar issue, but I had enabled the Y5-Battery Saver and it continuously switched off my WIFI when I was in place where I had not been connected before. Just wondering if you have enabled the same app...

No i havent, but thanks for the suggestion

[Q] Mobile data network doesn't disconect when on WiFi

3 out of 4 times my phone fails to disconnect the mobile data network when I connect to WiFi. This is draining my battery unnecessarily.
What could be causing this unless I can fix it so it is automatic I will have to stop using wifi so it doesn't waste power keeping both connections going.
I am running a 2.3.6 rom.
Do you toggle the connections or just enable/disable WiFi? When you enable WiFi and connects, does the 3G icon (the two arrows) appear next to the WiFi icon?
my phone does both I have a program that shuts it completely off when I go to work then back on when i get home based on time.the rest of the time it is on even if I go away which then it just disconnects but wifi is still on.
I have not paid enough attention to when it happens but when it does I have both the wifi icon and the data arrows at the same time.

I believe that the wifi driver is screwed up

if you 'long press' on the connection and tell it to 'forget', then you can 'do over / re-acquire'....
But nothing is showing up in range to connect to in the first place

darn, well then all i got is 're-install'. . . has the wonderful titanium back up - saved all your stuff ?
What I find that works is to cycle the wifi on and off a few times and each time you do go into setting for wifi and search for networks and eventually it shows back up. Just one of the uncommon bugs that happens at times. It will reshow back up.
I have found that if you launch WFI Analyzer when the WFI won't connect, and cycle the Off and then back On while Analyzer is running, it seems to make the WFI work again.

Problems when connected to WIFI

Does anyone else have problems when connected to wifi.
I find that my G-talk and DeskSMS just dont seem to work if I am connected to my home Wifi, and whilst I have AYCE data plan I would much prefer to use wifi when at home as I know Three can be buggers for traffic shaping.
Can you browse the web when connected to the wifi? Or is it just the 2 applications that don't work?
I think it just just background functions and refresh. Anything I do proactively works, so web browsing, or choosing to use g-talk or gmail. As soon as the phone is idle connected to wifi these things just dont seem to connect any more.
THough strangely they do when on 3g. Is off.
try to go into dialer and type *#0011* then press the menu key and select wifi. Poke the button under wifi power saving mode and press the back key multiple times.

i presume that is the same as going to advanced settings of wifi to check that wifi is always on even when the screen is off, correct?
My settings are that Wifi should be kept on during sleep so not sure it is this.
Is very annoying, if I want to use my computer to send texts I have to have wifi switched off on my phone.
The annoying thing is I cannot help escaping the feeling like it is some little, easily solveable thing. Grrr!
