I am using SM-N950F, rooted with SuperSU.. I am having WIFI connection issue since I have updated t OREO..
After few minutes my connections show Exclamation mark and "Internet mignt not be available" message..
There is nothing wrong with my router as is it working fine on other devices.. and it was working fine with Nougat..
Please anyone help me with this issue..
I have the same issue. Not found a solution yet.
It's annoying. I'm on unlocked btu btw
I have the same issue after the Oreo update... It worked for weeks after the update, and suddenly I am experiencing the same "internet might not be available" issue. It affects Play Store too, I am unable to download or update apps, they get stuck on "Downloading" and eventually fail.
It is very annoying. I hope someone has some way to fix this or some explanation at least...
My N950F is not rooted, I am using the XEF official ROM.
I've been having the very same issues, no matter which Oreo released I've used, hard resets make no difference either.
The only way I've been able to get around this is by setting the router to use TKIP instead of AES, it seems this is the issue as even when tethering (which creates a hotspot using AES too) the connected device drops connectivity too.
So in summary, try changing your routers encryption method to TKIP, it's not as secure as AES but at this stage, it seems to be the only solution I can find.
Same issue it's annoying and killing my battery
I had the same issue and was a problem with one modem, not with my phone, because at work the wifi sucked, drops, low speed etc etc, but back home everything was great (even faster than Nougat)
What I did was to change the wifi security settings, Encryption algorithm was "AES only", change it to "TKIP/AES" and the problema is gone.
Have you tried wiping the Cache Partition in Recovery Mode? If that doesn't work then I would recommend that you try a Hard Factory Reset

I have a Samsung Galaxy S Vibrant device and a strange Wi-Fi connection problem.
It seems that the WiFi conneciton is being lost intermitently with no apparent reason. I ping the device, most of the time there is a 'Request timed out' and only sometimes a 'Reply from <address>'.
On the device side the connection behaves erratically as well, sometimes there is connection but most of the times there isn't. The strange thing is that under device's Settings->Wireless and network->wi-Fi settings the connection's status is "Connected" all of the time, signal strength is excellent, link speed is 54Mbps.
I had this issue on a native 2.1 Samsung Galaxy S Vibrant install, then decided to flash a custom 2.2 ROM hoping to end the mistery. The new custom ROM is an Axura21VE.zip and the WiFi connection problem is exaclty the same as before.
Does anyone have the same WIFi issue as I have? And yes, I did a search before posting this. In fact, I searched for several weeks and saw many SGS Wi-Fi problems being reported but either they are different or they are similar to mine with no solution. Since I need a stable Internet connection on the device for app development, next logical step would be looking at reverse USB tethering. Yet decided to post here before giving up on Wi-Fi.
For the record, the Wi-Fi acces point is under my control, i have a ASUS P5B-MX/WiFi i946GZ motherboard, windows XP sp3. I tried, I think,
every possible combination of Wi-Fi settings available. The only client device I have at home is SGS. At the office network, SGS is having the same
Wi-Fi issues, while a HTC Desire and many laptops don't.
here is what I just found out: if I do a constant ping form the device to google.com for example, then the conenciton is maintained all right. So, should I constantly ping something to maintain a decent connection? Is there a setting or something in Android OS I am missing?
I had this exact problem - changed my router and it works perfect now. Really weird and not an ideal solution but worked for me so far (touch wood!). Try playing about with your wifi config maybe, change encryption, channel etc. Good luck.
Hi, I'm having the same problem on my Galaxy S i9000 on Darkyy's v7.8. I never used to have this problem until I flashed the second to last release. The device says I'm connected to the network but I can't get any internet access. I tried reflashing my official firmware DXJPA, but I still no joy. I'm not really sure what to do.
YES... i have been searching for days. I feel I may have a similar issue. im connected, speed good, IP there.. no data, browser just hangs. seems to happen less in stock. (Rogers captivate, P10.1) also WiFi manager reads my WiFi channel off by 2!! so im set to use ch 9 on the router and WiFi manager on the captivate says its broadcasting on ch 7?? any ideas? ping to infinity??
side note: this happens on all routers and all roms. other galaxys on my network read proper ch... GF's Iphone see the right channel?? HELP..
I'm also having these problems, reposting my reply from another forum:
Just wanted to chime in that I am also having these problems with my samsung vibrant. Seems to only happen from my work router but happens very consistently. Wifi will work immediately after setting it up but after a short time period will stop working completely. It will say it is still on wifi but will in fact have no access to the local network or the internet. Stopping/restarting the wifi connection doesn't fix it. The router has to be manually 'forgotten' and then re-added for it to begin working again. (Update: sometimes this does not work either, in fact).
This is with a 2wire modem (standard issue by at&t) using WEP security in 802.11b/g mode.
Some people recommended switching from 201.11b/g to pure 201.11g. I tried this with no luck. It was also recommended to try to app 'wifi fixer'. This also did nothing to solve the problem. Given that it is my work router, I don't want to go changing the encryption and other crazy things as I'm not the only person using this router and it would break the connection for others.
MRSizzle in another thread (which xda isn't allowing my to link to) seemed to accurately describe the problem as such:
"It appears to be a driver issue with the Samsung base OS drivers in the phone. Possibly sleep policy is not operating correctly and the wifi radio is being disabled by the hardware and is not being controlled correctly by the software so the WiFI icon still appeers to indicate the phone is connected. Also the wifi signal is not being correctly reported. the signal appears to be attenuated more than it really is."
This description would line up with the OP's reports that repeated pinging will keep the connection alive.

Anyone figure this out? I'm trying to use the Web Desktop app but can't because I can't even establish a connection with my phone!
Hi friends,
I have similar problem, but at first I easilly connected to Internet, but now I can connect to my WI-FI but no internet connection. I am not sure but maybe this has occur after updating to Android 2.2.
Any suggestion?
Thanks in advance.
explanation and apology
I was wrong in my assumption that it's an Android device problem. The problem was in the Asus motherboards embedded Wi-Fi access point. I bought a separate Wi-Fi router and now everything works like a charm.
Since a few days I'm running the ICS stockrom on an unrooted Note. Before on the GB I was have not the best reception with Wifi, but it was working. Now, with ICS, my Wifi is connecting/disconnecting/connecting/and so on within a matter of seconds. I'm experiencing this on multiple Wifi networks. Therefore I would say it does not concern the settings of my Wifi network, also I'm practically sitting on the router (channel, reception can't be issue).
I've installed ICS via Kies and have done an additional factory reset today.
Does anybody know what could be the cause of this? And, more important, how to solve it?

Others have had similar issues - try reflashing the same modem from here:
http://forum.xda-developers.com/showthread.php?t=1645202
I found that wi-fi and data both worked better after flashing the modem a second time.
Thank you very much it seems to be working!!
I had to look to find out how to get the phone in download mode, but got it.
Sad to say I did an unneeded factory reset this morning, but yeah it is working now!
I've been also noticing momentary WiFi disconnections ever since I upgraded to ICS.
I'm using MyPhoneExplorer to transfer files wirelessly to the device (not via USB), and ever since ICS it has became an unreliable way to transfer files. If I transfer a big file most chances are that the WiFi connection will drop during the transfer, causing it to fail.
The connection is restored immediately but then I have to restart the transfer process as it halts when the connection fails.
I have excellent signal level (physically located close to the Access Point), I tried flashing the latest modem firmware (XXLR1) - twice, I've set "2.4GHz only" in the WiFi advanced settings, all to no avail: I still get these connection drops.
The same setup (phone, access point, etc) has all been working well in the past with GB. Now with stock ICS it performs poorly.
Has anybody got any information about this problem? Been experiencing similar problems?
Thanks!
I've been getting this issue too but it seems to only be with our virgin router, all other devices connected to it are fine although the signal is a bit crap on them to its at least stable
I tried the modem flash etc but no improvement, I'm pretty sure its the ****e virgin router

At my side it seems to be working better now, steps I've taken (in this order):
1. Flashing new modem
2. Enter fixed IP address for my home Wifi
3. At Settings->Wifi->Advanced->Leave Wifi on when enabled
Especially the last seems to have done me good. I have it working in combination with BatteryFu so it does not consume my complete battery.

Well, the AP that I had problems with is a relatively recent D-Link 802.11n router. Nevertheless, I tried connecting with an old Cisco 802.11g router, and lo and behold - connection is now stable.
So, looks like there is indeed some interoperability problems but I won't dismiss this as a "****e <X-company> router" - as the same router is working well with other clients, and moreover, was working well with this phone when it was running an older GB firmware.
My conclusion is that apparently somebody at Samsung / Google has broken the Wi-Fi drivers, interoperability-wise.

You probably mean leav wifi on when screen is off? My phone is already set this way... Anyhow, thanks, but it looks like this is a problem with a specific router as I wrote in the first part of this message.
After updating my S6012 aka Samsung Galaxy Music Duos to JB by looking at this guide..
http://forum.xda-developers.com/showthread.php?t=2415442
My phone networks 3g and WiFi have lags..
In WiFi mode it connects but network is not found..
In 3g mode it takes so long to on even www.google.com..
Anyone else have same problems??
First time i did it worked fine then few days ago i sent the phone into bootloop and then did it second time two days ago..
Please help..
Did you factory reset after the install?
verify the connection first
Well i didnt factory reset and i use the WiFi network for some time now on my laptop without problems..
Now WiFi works for few seconds before it shows no connection.. It downloaded a 1.1mb file before the message came..
Any ideas why it is doing so??
Is it any settings or is it any root app??
Want fix soon as i need my android for mobile forum using..
I've found that many OTA updates cause weird issues if you don't reset afterwards, especially Samsungs. What did you do to make it go into a bootloop the other day? Is it all wifi networks that are having issues or just at home? Have you tried forgetting the network and relogging back into it and / or resetting the modem and the router if it is only at home? It doesn't matter if every other device is working, resets can often help if you have narrowed it down to just 1 network. As far as the 3G, it's hard to say. The modem/baseband also updated and not every version works best in every region. It's possible you might see if there is another version of 4.1.2 that would have a different modem to flash.
i tried activating softkeys in my rom by editing build.prop..
tried forgetting and relogging..
strange thing is 3g network lags less..
it's as if it is getting better as days pass by from flashing..
Working
I updated My ROM to CM10.1.3 by Alonso..
Now everything is perfect..
Hello,
I recently flashed .575 on my Z3C, now WiFi connection is unstable, disconnects after a while. The consequence is that updates do not work correctly, file transfers through WiFi are often interrupted. Did any one notice the same behavior? Any fixes (tried different AP and to reflash the FW)...
Thx
Problem persists in 23.5.A.1.291
Similar issue here
I also have problems with the latest 23.5.A.1.291 firmware. There are two problems in fact, sometimes it disconnects and can't reconnect anymore without rebooting and the other is that, while it still seems connected to wifi, it's effectively offline as internet doesn't work anymore, after a while it starts working again.
It's a pity because the Z3C was the device with the best wifi and coverage that I've ever tried with the previous Lollipop. I partially resolved the problem, meaning that it happens less, changing a few parameters into the router, disabling every possible feature, still isn't completely resolved...

I'm not OP, however I tried that setting but it didn't improve much. After all, DHCP is a protocol which should be used only at connection startup theoretically
I also have the same issue, however installing Auto Wifi Manager seems to have helped -

Already tried but it didn't helped. As for the issue, for me it disconnects and reconnects instantly even with full signal every 5-10 min. So it does not eat my mobile data however every lengthy file transfert by wifi might be interrupted.
Tried different channels, 2.4ghz, 5 GHz on two different routers at home, on several public Wi-Fi AP, behavior is still the same.
If screen is on the connection stays but is sometimes interrupted and reconnects directly. If screen is off Wi-Fi gets cut for 2-5 min then reconnects (according to logcat, might be Doze? Wi-Fi is set to be always on). Tried also a full reset of radio settings.
Solution
Does not work unfortunately.
I might have a good news for you guys. I think I finally managed to solve the issue:
1) Download a Lollipop FTF
2) Open flashtool in Flashmode for this FTF and exclude everything except packages beginning with AMSS* (it will not alter any data on the phone and it's very quick, also does not need to regenerate the dalvik cache)
3) Flash
-> You just replaced the baseband / modem with the Lollipop one. Tested briefly on mine and so far no disconnections
Same problem here, after update to .575, and .291 didn't help.
Sometimes when I open WiFi networks phone doesn't find any network at all. Also bluetooh is acting weird sometimes (disconnects, can't turn on).
Tried with DHCP and clearing radio settings, and even downgrading to 23.4.A.1.264 and 23.1.A.1.28, didn't helped.
May be it is hardware related... I am on 4.4.4 and have same issues. On some routers better, on some worse. Also sometimes works ok for long time, next day same place disconnecting...
In my case, everything was OK until upgrade to MM

For me downgrading to Lollipop 23.4.A.1.264 solved the issue but as soon as I install Marshmallow, even a clean install by PC Companion the problem reappears. So I will stay on Lollipop for now, it also has Stanima
I think something is wrong with the way Marshmallow manages the WiFi connection

you're right. but luckily this problem can be solved! go to Developer options in Settings and check "Use legacy DHCP client". then reboot your device - problem solved!

Is anyone else experiencing wifi issues? Meaning, when I turn my wifi on I cannot access most data related apps. If I turn it off everything works just fine. Yes, my access points at work/home are top notch and working just fine (network engineer here). I am simply wondering if it is isolated to just my Note 8.

Mine also has wifi issues. Seems nothing gets thru with 2.4 or 5ghz. Signal is strong but no data. But it seem to happen after I restored with Smart Switch. I just factory reset the phone due to this wifi issue. After reset, wifi works fine, downloading playstore updates, samsung updates, etc. After restore it seems to cut out randomly...
edit:
just found this article, https://www.gottabemobile.com/common-galaxy-note-8-problems-how-to-fix-them/ and it mentioned smarts switch restore might cause wifi problems. Solution was to forget and re-connect. That seem to have fixed it for me, at least for now.
