I updated my AT&T Galaxy S3 to Android 4.3 a few weeks ago.
Ever since then, I routinely get a notification that says "Your Internet Connection is Unstable".
It seems to happen each time I turn my bluetooth connection on.
Phone on > connected to my home wifi (2.4 gHz) > bluetooth is off > turn bluetooth on > get the "internet connection unstable" message.
If I keep my bluetooth off, then I never get this notification.
I have already wiped the cache partition as noted from thread http://forum.xda-developers.com/showthread.php?t=2484032
Has anybody else noticed this "coincidence"?
Blooth Drivers
I think BlueThooth Driver Or Wifi Drivers Are Not Perfectly Installed ..
Or Check By Connecting To Other Wifi Networks.
Press Thanks If i Helped
FIXED
Here's what I did:
My router is an ASUS RT66U and I was connected to the 2.4 gHz band. There is a setting called "b/g protection". I turned this off and my phone no longer shows this notification when I turn on bluetooth.
Ultimately, I ended up using the 5 gHz band on the router because it seems that the 2.4 gHz causes some interference with the bluetooth because they both share that 2.4 gHz band.

U Mean when u off bluetooth the unstable notification automatically goes...

When I had my EVO 4G I had no WIFI issues at home or work. When I got the EVO 3D I had serious issues with WIFI (at home only) and I kept blaming the phone. Well after turning some options off (like turbo boost) and playing with bandwidth settings) EVO 3D became solid.
Now EVO 4G LTE is having WIFI issues. I had started a thread using 2.4Ghz for WIFI which was a huge help. But it's still not quite right. You can see it frequently flipping between WIFI and 3G. The phone again works fine at work. If I have to I'll buy the same wifi routers I have at work.
So I started digging into Router settings again and noticed this "WIFI Coexistence" option (which was set as disabled).
So I researched it on the dd-wrt.com web site (the open source I run on my router and found some interesting info).
I think this may have something to do with some folks issues.
It may also account for why some people say they have no problem and others do.
Even when you swap your phone your Bluetooth devices might choose a different channel when you pair it and have less conflicts. On old WIndows phones even when you unpaired it, it would cache the old channel and use it again if you repaired it.
I'm going try this option and try running with bluetooth off and see if it's more stable.
I have had bluetooth issues as well. Mainly after a call, the would disconnect from headset and headset could not reconnect without toggling bluetooth on the phone or headset (or both).
This is a copy of what I found on dd-wrt.com
==================================
I found a clear answer on TomatoUSB's website:
Bluetooth Coexistence
An 802.11 device and Bluetooth can interfere with each other when the 802.11 device operates on the 2.4 GHz band. All Bluetooth devices operate at the 2.4 GHz band. If you experience wireless disconnects, decreased range or speed, and other connectivity issues when you turn on some of your Bluetooth devices, try to change this option to "Enable" (this will make the router and Bluetooth device to take turns in using the spectrum for communication) or "Preemption" (the router will inform the Bluetooth device about the channel it is operating on, and the Bluetooth device can preemptively disable communication on the respective Bluetooth channels).
Please note that this option requires your Bluetooth device to "cooperate". If the Bluetooth device doesn't implement the coexistence techniques, using this option will have no effect.
I'm 99.99% sure it's bluetooth causes WIFI issues for me.
If your having WIFI issues (which interferes with 3G as well) and you normally keep bluetooth on.
Try as simple experiment leaving bluetooth off (I know you should not have to).
I left mine off today and data was flawless.
Switching between 3G and WIFI was instant and smooth.
When I wake it I see it jumping around between 3G and WIFI.
This phone uses a Qualcomm bluetooth stack and EVO 3D and EVO 4G used broadcomm.
I never even thought to consider bluetooth.
Bluetooth has been bumpier on this phone as well.
If I leave WIFI off, bluetooth runs perfect.
I need more data though to sort this out.
I always leave Bluetooth off when at home, its only on when my phone is in the car dock. But I still couldn't even get through a speed test without wifi disconnecting completely and the test failing.
Ironically, I do not have a single drop out when at work, only at home.
I set Bluetooth Coexistence in my router's settings to Preemptive and so far (5 minutes) so good (I do have other bluetooth devices in the house).
Will report back after further testing.
Oddly, no other devices in my house have ever had this problem, so there is still something funky with the new Evo. But luckily with all these software fixes having varying success with people, it doesn't look like a hardware issue.
Still not a single drop out that I've noticed.
I'll know for sure in the morning. My Titanium Backups to dropbox have failed every.single.night with this phone due to wifi dropping connection in the middle of the upload. We'll see if they complete tonight.
Looking positive.

Awesome. Thanks for the update.
I agree it's odd this Device is stirring up the issues.
But it could be something as dumb as they scan for available bluetooth channels in a different order and tend to hit channels that conflict with WIFI.
Most WIFI I think is on channel 11. I have mine on channel 11 as it seems teh best compromise for the many WIFI devices I have so I didn't want to change it.
So folks migh thave more flexibilty, and just changing WIFI channel can make quite a change.
I'll have to check work, what channel it's on. I'm pretty sure it's not on channel 11 because we have multiple access points and we wanted teh channel non overlapping. So we have them set at both end of teh range if I recall.
That could be a hint as well.

I think you're onto something... If I leave the house and wifi sticks on, then I normally have to reboot phone before I can connect to wifi again. Simply toggling wifi off and on doesn't work.
So on a whim, I turned off bluetooth. Then turned wifi off and back on, and bam! Connected! Hmmmm....
Now with reference to co-existence, that can't be the "fix" because not everyone has access to their router settings (such as at work, hotels, malls, etc.)
WiFi works perfect Bluetooth on the otherhand, haven't tested. But I'm sure works just as fine

After I selected 5Ghz only, the option to select the wifi frequency band is no longer there?? Help!!
These are the default options which are supposed to be available :
Network notification: By default, when Wi-Fi is on, you receive notifications in the Status bar when your device detects an open Wi-Fi network. Uncheck this option to turn off notifications
Avoid poor connections: Check to automatically avoid using networks with a low-quality or intermittent Internet connection. <- this one as well!
Keep Wi-Fi during sleep: To conserve mobile data usage, your device stays connected to Wi-Fi when the screen goes to sleep.
Touch this option to change this default behavior: either to stay connected to Wi-Fi only when the device is connected to a charger (when battery life isn't a problem), or never to
Stay connected to Wi-Fi during sleep. The latter choice is likely to increase mobile data usage. You may want to revisit this setting if you receive a notification that you're approaching your specified mobile data limit.
Wi-Fi frequency band: Specify Automatic, 5 GHz, or 2.4 GHz frequency bands <-- this option is missing
Any ideas? Thanks!
Also, it's not just my default 2.4GHz band missing, even the neighbors. There were more than 10 when I scanned for them previously
Same problem here
I have the same problem on my Galaxy SIII... I chose to disable the 5Ghz band (2.4 only) in an attempt to suss out the problems with my phones wifi connectivity. I duly forgot about the setting until recently.
Between then and now - there was an update to my phone (which I did apply) - and now the advanced menu for Wifi does not contain an option to choose the Wifi Frequency Band... I've tried looking for 3rd party tools that allow you to set this - but haven't found any yet...
I'm on Android v. 4.0.4 with T-Mobile. Does anyone know how to set the frequency band back to Auto?
Much appreciated!!

Have you done a factory reset? If not, go to your recovery and delete cache and data. There are no other options if you don't root that comes to my mind.

Twice, but it didn't help.
I seem to be getting the same sort of wifi issues as previously stated elsewhere in this forum. I cannot hold a wifi connection on the 2.4ghz band fro more than 20s before its dissociated (ie i still have full connection to the router (3 bars) but cannot get through to the internet). This happens no matter what router i am connected to, whether its at home or at work.
I have tried:
[*]Setting the Wifi optimization checkbox off. No difference
[*]Avoid poor connections is off. No difference.
[*]Stamina mode is off. No difference.
[*]Keep Wifi on during sleep is set to Always. No difference.
[*]Sleep timeout to 30mins. No difference.
[*]I have factory reset the phone. No difference.
[*]Repaired the phone firmware with PC Companion. No difference.
I have also check to see if it is my router at home. I have switched between every channel available which made no difference. Security is Wpa/Wpa2 PSK AES which makes no difference. I only have the 2.4ghz available on that router at home (same at work).
My Note 3 and HTC One connect to both routers with no problems at all and do not drop out. Same goes with Sony Vaio Laptop.
I have installed Wifi Fixer on my Z2 to see if it can alleviate the problem and it does somewhat. instead of manually having to turn on and off the wifi toggle to reestablish a connection, the Wifi Fixer does it for me.Approx. every 20-30s in its log it will show the phone "dissociating" from the router, and the the app tries to "reassociate" the connection.
I can connect through wifi transfer to my Note 3 without issue, and the same goes for my TV, so it cant be a hardware fault, as the connection is still excellent strength for both (as well as the router, tested with Wifi Analyzer). This is a very frustrating problem as it makes watching youtube movies impossible, and hotspotting, skype calls, etc.....
And dont even get me started on the bluetooth dropouts. I am disconnected from a bluetooth connection every 66-70s without fail no matter what i try. No issues with my Note 3 and HTC One in the exact same conditions. It will disconnect then reconnect straight away with a delay of about 3 seconds, which makes calls and listening to music a VERY unpleasant experience.
Any ideas on how to fix this? I love everything else on this phone but this wifi/bluetooth connection issue is making it unusable. :crying:
I am on the .55 baseband version if that helps anyone
(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'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.

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

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'm running into an issue with my watch receiving notifications over wifi at my workplace. We have two wireless networks: one 2.4 Ghz and the other 5 Ghz. I have my phone currently on the 5 Ghz network with my watch set to Automatic. I have noticed that whenever I'm out of bluetooth range, my watch shows that it's lost connection with the phone. From what I know (and have double-checked), the watch should still be able to get notifications from the phone via wifi. But that's not what's happening. Is it because the Zenwatch 2 isn't compatible with the 5 Ghz band or am I missing something? If it's not, can I add the 2.4 Ghz network to my phone in the hopes that the watch will connect to the 2.4 Ghz network while the phone stays on the 5 Ghz network?
Answer from Android Optimizer:
I have a dual band network at home, and my watch seems to have no problems working while connected to the 5ghz band. If you go into the Advanced section of Wifi settings on your watch confirm that your watch is getting an IP address and Mac address while connected to the 5ghz. Open Android Wear on your phone, and send test notifications from the three dot area to your watch and confirm that it receives those notifications. Open ZenWatch Manager on your phone and confirm that it is reporting the same information as your watch (ex: watch battery %, etc). If all that checks out then something other than the Wifi network band is likely interfering with you receiving your notifications.
Nope. Only 2.4GHz.
My home has 2.4GHz and 5.0GHz but the watch. Can connect 2.4GHz. And I do believe in view of battery life... It tends to disconnect from Wi-Fi. Even if it's Automatic...
