(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.
`````If smart network switch is enabled, your device will be connected to a mobile network automatically when the Wi-Fi connection is unstable. `````

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?

Liksys E4200 802 11 N router

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.
