Hi guys,
Do you know if AT&T automatically prefers WiFi over 4G? If not, is there a way to set it so that I can save on my 2GB limit imposed by ATT? thanks

Set WiFi sleep policy to "never" - then the only things that will use cell data when you are connected to an access point are market checkins (but not market downloads) and MMS. Maybe not even MMS.
Note that the phone won't automatically connect to open APs that you haven't connected to before.
If you have wifi sleep policy set to "when screen is off", background data will be over the cell connection.

Sorry but I can't find this setting. I'm looking in power saving settings and the only thing i see is turn off wifi when NOT connected with mobile AP. Does mobile access point mean wifi or cell data?

thanks,
just checked and its set to never.
I think you want to control access of data retrieval via cell network, right?
what I did was set the receiver options to airplane mode and then only enable the WiFi. That keeps the cell net from connecting. Also d/l an app to monitor your usage for piece of mind.

If you do that you don't receive any call or sms, no?

With APN On/Off, it's a free app. I turn off the data and can still do everything else. It even has an option to keep MMS enabled
Been having some intermittent trouble with wifi on my verizon sgs3. Sometimes while connected to wifi the connection will drop. If I go into wifi settings, wifi is still on but no access points show except ones that I've previously connected to and "scan" doesn't seem to do anything (not even the little spinning indicator).
If I turn wifi off/on all is well again.
Ideas?

Typical working gs3.
There's a number of threads with WiFi problems and solutions.
Short list
1 update routers firmware
2 no dual encryption
3 some routers with 300 or greater Mbps settings need to be toned down to 150 or less
4 phone likes mixed protocol network over N only.
5 turn off phone power save
6 un check the carrier hot spot notify.
7 un check open wifi notify
8 pick a single band 2.4 or 5ghz. Note that updates with this can temporarily lock in to that frequency and not allow changes.
9. Dial *#0011# menu button, wifi and turn off the power save setting. This has to be done on every boot, and may cancel the display timeout.
10 On 5Ghz don't use DFS channels
BTW Isn't it great to have 35,000 hot spots for wifi that are only useful if you're standing still?

11. YES, lol. I generally turn my wifi off unless i'm planning on being stationary
Thanks for the suggestions!
I am having serious wifi issues on my T-Mobile P769 20f Jellybean which makes wifi pretty much unusable.
I have the following advanced wifi settings:
Keep wifi on during sleep = always
avoid poor connections = disabled
wifi frequency band = auto
When I am connected to wifi it will be for no longer than a few minutes before the connection drops. Sometimes it restarts on its own. Sometimes I need to kick it by toggling wifi on and off.
When I am connected I have piss poor link speed, only 5 mpbs. The connection is very slow. It took me on the order of 5 minutes today to download "wifi analyzer", an app which is less than a megabyte.
When I set wifi frequency band to 5ghz, I don't even see the 5ghz network which my dual band router (Asus rt n66u) has created on a separate SSID altogether. I only see my 2.4ghz network but trying to connect to it by clicking on the name does nothing.
When I am connected to my 2.4ghz network I have changed the ip settings from DHCP to static and that doesn't seem to help as other threads I have read suggest. My connection still frequently drops.
Finally I wish to try changing the wifi power saving setting by dialing *#0011# but that just yields "invalid MMI code".
Does anyone have any ideas? I am at my wits end with this wifi that is unusable and I am currently roaming so cannot turn on my data. It seems to me that this is the infamous Jellybean wifi issue but maybe not.
Any help is appreciated.
Yeah jellybean has a lot of problems, ice has the best Wi-Fi driver. I think wind 21b has good wifi, it's been awhile since I've been on that Rom, so I might be wrong. Maybe we can port the wifi driver from ice to the jellybean, not sure if we can though.

It may sound stupid but have you checked that your router firmware is up to date? Other than that I would try a backup if the problem wasn't pre existing. Last resort reflash it.

I had this problem whenever I have any "battery saving" app running (Battery Saver, Juice Defender, etc.). Turn them off and have my wifi on all day (or maybe using Llama / Tasker to turn wifi off at night) solves my problem.
(April 24th, 2015) After searching for a solution to my wifi dropping I collected a comprehensive list that has helped in one way or another. After seeing similar issues on S5 phones it appears this isn't solely a S6 problem. If you find or have used a method not on the list please report and I'll add it.
Possible fixes for Galaxy S6 WiFi problems:
Factory Reset
“Forgetting” your Wifi Network and Reconnecting
Settings ->Wi-Fi. Hit menu then Advanced. Make sure Keep Wi-Fi on is set to Always.
Settings, more networks, mobile network, uncheck Connection Optimizer
Under the Wi-Fi settings uncheck "Smart Network Switch"
Resetting the Modem/Router
Settings→wifi→WPS Button and same button on modem/router to 'lock on'
Switching from DHCP to Static Connection on Phone
Connect to your router's 2.4GHz band instead of 5GHz
Install a DNS changer app, select primary/secondary servers to Google or yandex.
Changing the Router Bandwidth Settings
Changing the Router’s Broadcast Channel
Adjusting the router security settings to WPA or WPA2
Enable WMM in your router settings
Disable IPV6 in your router settings
Calling your ISP and upgrading to a Higher Bandwidth/Speed
Wipe phone cache
1) Power off the Samsung Galaxy S6
2) Hold the power off, volume up and the home button all at the same time
3) After some seconds, the Galaxy S6 will vibrate once and the recovery mode is started
4) Search for the entry called “wipe cache partition” and start it
5) After a few minutes the process is complete and you can restart the Galaxy S6 with “reboot system now”
Disable phone's wifi power saving mode
1) Open your phone dialer
2) Enter *#0011#
3) Select more (top right)
4) Select WiFi
5) Turn off WiFi power save mode(enabled by default)
6) Exit and hopefully your WiFi connectivity issues will no longer be a problem

(April 11th, 2015) Anyone experiencing wifi dropping out? It seems to happen when I require it, ie browsing themes or downloading apps. It will lose wifi and the lte icon appears and the screen freezes temporarily until wifi is restored. Last night this happened like 6 times one after another which wasd very annoying.
WiFi working petectly fine connected to my as router
Sent from my Samsung Galaxy s6 Edge
Yes, I am having the same issue. WiFi drops out, screen freezes and then WiFi comes back and everything works again :/
It seems to have settled down a little now, only seems to happen when there is quite a bit of WiFi activity.
It kept happening to me while I was downloading a GPS map and also when syncing Spotify.
I am connected to a 5GHz AC router, what sort of connection are you using?
Yes,
My device has also done this also around 4 - 5 times and i was thinking could it be Smart Network Switch which is on for me.
i have also noticed the wi-fi has dropped out for when the phone is asleep and i awake it.

I don't have Smart Network Switch enabled, so it isn't that for me.
My WiFi always stays connected through sleep though.
What sort of connection are you on? G/N/AC/2.4GHz/5GHz?

i am on a 5GHz BT hub 5
My Smart Network Switch is off and I'm in the same room as my router so signal or the setting isn't the issue. Anyone using a Sprint Airsve in-home signal booster?

I'm going to a friend's house later and will see if the same issues occur on his network.
I'll be able to do some tests at work tomorrow.
I haven't had it happen today at all :/
I downloaded Angry Birds Space 3 times this morning and no wifi drops. I was on the road and something locked up where I couldn't swipe between home screens or open the app drawer, noted I had wifi on even though I was in the car outside of a network. Didn't get to test the wifi at my friend's house but just tried downloading AB again and wifi dropped out.
This is getting annoying. Thinking I might see about going in to BB to exchange, this isn't a glitch I can live with or risk being a hardware defect. I plan on contacting Samsung to make sure they make a note, hopefully they are aware of this.
Galaxy S6 (not the edge.) Same issue. Wifi drops. Music stutters. Have to turn wifi off and back on to reconnect. Using Apple airport express.
Same thing here with galaxy s6 edge. Wifi keeps dropping out. Web pages too slow to load.
Will return the phone tomorrow.

Jesus, these phones are gitchy as all hell. I get mine Thursday. Going to mess around with it for a week and if I keep having these same problems I'm just going to return it and move to something else. I've never seen soo many issues with a new phone in both software and hardware.
If anyone can test other wifi networks or exchange phones, please report back with results.
Googling turned up a similar problem people had with the S5, some found fixes while others didn't.

I tried a few of those, others aren't necessary. I did 2 factory resets and the wifi was fine downloading 54 apps but dropped at the last one, and lasted all 55 but dropped later. I'm going in for an exchange tomorrow unless someone posts a magic fix.
The Recomhub website helped me fix my WiFi dropping problem. Thanks for the link, it really solved my issues!
5GHz Network
I've been testing this, because it is really annoying me now.
When I am connected to my 5GHz AC Network at home it drops out and freezes the phone quite a bit.
When I am connected to my 2.4GHz N Network at home, there is never an issue. Wireless actually seems to work better on this network.
So, for me at least, this problem is being caused by the 5GHz networks and switching back to 2.4GHz makes the problem go away.
This is an annoying bug, I have emailed Samsung about it, let's see if anyone replies.
My router is Simultaneous Dual-Band N (2.4 & 5 GHz) so I wonder if that is causing my issues. No idea how to remedy it at the moment.

Mine is too, but I have the ability in the router to separate the two networks, so my 5GHz network has a different SSID than the 2.4GHz one.
I've been connected to the 2.4GHz network all of tonight and done quite a bit of downloading to test it and it hasn't dropped out once, yet on 5GHz it would have done it at least twice already by now.
I cannot replicate this problem at work on the 5GHz Network. It must be something to do with the channels they are set at.
I will try and change some channels on the work network, see if I can get it the same as at home and then test again.
I have a call booked with Samsung who are going to remote my phone, hopefully they can pinpoint something
I can't even connect to my home's 5GHz, the 2.4GHx is what I'm testing.
I went to BB Wednesday and the Samsung rep wasn't aware of any wifi issue or remedies beyond what is mentioned in this thread. Of course I didn't lose wifi the brief time on their wifi network so the guy didn't know what to say other than contact Samsung support.
I tested this at my house last night.
64GB White Edge AT&T on 5.0.2
E3000 router with DDWRT
N700 Router with DDWRT
Both dual band, both running 2.4 and 5 Ghz
Both set to 40 channel width
Both with channels spanned correctly for no overlapping
Never lost connection while downloading and updating all apps throughout about 2 hours of use. Speeds saturated my broadband link (50Mbits/Sec) and never had a problem. However, I don't know about battery drain as I'm brand new and still letting everything settle for another few days before commenting/testing.
I have an issue with wifi notification, not sure if it's hardware or software (that's how EMUI is).
my previous phone always notify me of available wifi networks when I am not connected to one, my HM20P doesn't do that. I literally have to go into Settings - Wireless & Networks - Wifi ...... to see which wifi network is available to log in.
Also, when I press on Wifi in the Notification area, it just toggled Wifi On or Off, doesn't open up Wifi Settings......is that normal?
International model, bought in canada.
