S8 Internet connection may not be available issue - Samsung Galaxy S8 Questions and Answers

Just got the S8 and I have 3 Wi-Fi access points at home to cover the whole house. My S8 has been registered with the passwords for all of the APs but it continually rejects the connections with an exclamation mark after the WiFi icon having connected and then shown a message that the Internet connection may not be available. The Internet connection is available as other devices are connected and using it perfectly. If I switch the Wi-Fi on and off and reboot the S8 the issue corrects itself but I should not have to go through that nonsense every time I come home and want to use my Wi-Fi. I have explored the advanced options on the connection settings and they appear to be quite limited (DHCP Etc). Is there some way to solve this issue? I have no problem with other android devices connecting to the same hotspots. Any ideas that might lead to a solution would be appreciated.

I had this problem when i first got my s8 from vodafone but when i got this latest update it's been good no issues with internet anymore.

I have this problem as well with my S8 from Verizon. Worked flawlessly for a week and them today I get this error. Very frustrating. I know the SMG955U from Verizon is already unlocked but is there any way to put the International ROM on the phone seeing that the Verizon and the International are the same?
I've tried all the resets etc and the WiFi connects but I get the 'Internet connection may not be available' message.

Update 27/04/2017
Thanks for the reply. My S8 developed some interesting issues including the switching on of 'do not disturb' mode intermittently and along with the Wi-Fi issue the mobile data was failing in areas where a full 4G signal was present. Rebooting, resetting etc did not resolve the issue and I returned the phone to CPW for advice. The staff at the Glasgow store wasted no time and exchanged it on the spot after some negotiation with their technical service centre. Full marks to CPW for the prompt service and I can report that all of the previous issues have now been resolved with the replacement handset. I thought it worthwhile to post this information so that others who experience similar issues may be able to get a similar resolution.

Poor WIFI performance
I also have issues with the wifi of the phone, /i will get the terminal replace some time today or next week.
1. WIFI keeps disconnecting, actually it's flapping connct&disconnect for 5-10 min until it finally connects, on this matter I have seen on the acces point that it tried to allocate an ip from an unknown without asking DHCP server for an IP renew it actually tries to alocate itself the last known ip, and clearly disconnects because of lack of internet access, this happens normally as power saving mode is on, disabeling power saving and assigning a static ip on the phone seems to resolve the issue.
2. poor wifi signal... no fix for this thus far
- i have 580Mbps speed connection on my S5 and only 120-240Mbps on my S8, steaming not working and connection in general very bad, time ots and stuf, although I position myself at 10cm away from the wifi router antenas i only get 540Mbps signal, although I have an AC1750 router , s5 gets 840 in the same spot... I think the modem(that is part of the Exynos chipset) does not work wekll with Atheros based AP´s , I have an Archer C7 with 2.4ghz QCA9558 chipset capable of 450 Mbps theoretical speed, but only uses 2 antenas as s8 only has 2 from my knowledge and reaches a max of 140Mbps(should of connected at 300Mbps at 10cm in theory ) with the s8 and QCA9880-BR4A on the 5ghz side of things with a theoretical speed of 1300Mbps should work at 866 with the S8 because of the 2 antenas of the S8.

phone changed 90% of problems fixed
Hello, just got my phone replaced, tha new unit has way better wifi signal considering I hace atheros router and the phone has broadcom 43xx chipset... worth considerign changing to a broadcom router...

Hi,
I have found a solution to this problem.
1. GO to wifi settings
2. Forget the wifi network
3. CONNECT AGAIN BUT BEFORE CONNECTING GO TO ADVANCED OPTIONS AND CHOOSE STATIC INSTEAD OF AUtOMATIC. Enter in the ip address etc and connect.( It requires to be entered manually) Problem will be solved.

Change the DNS...
Hi there..
I had just the same problem with s8 plus and s7 edge(after updating to android 7.0), it kept saying "internet may not be available", I changed the DNS to 8.8.8.8 and tue problem solved. Go to SETTINGS》WIFI》SSID》MANGE NETWORK》change the IP SETTINGS to STATIC》then change the DNS1 to 8.8.8.8 hit save and you are good to go.
Sorry if there are any mistakes. I am new to XDA and not good in english.

I have same problem and it is very annoying. I got 2 S8 plus and both have the problem.
There are 3 WIFI Router that covers my house. I have problems saying internet might not be available every time I connect. This is very annoying. Other Phones in the house like Iphone do not have the problem.
What I noticed is that the IP range of my router is:
192.168.1.1
But my S8 says he is connected but the IP is
192.168.0.100
Anyone have same problem?
Thanks!

I found a quick work around on how to fix this temporarily until Samsung issues a patch.
just turn off 5ghz SSID broadcasting and you should be ok for now.
here is a quick how to video i made on just in case.
https://youtu.be/Nu5FjDPLn-M

I'm having a very similar problem with my home WiFi and my Verizon S8+ I bought from Samsung's website. I've tried switching from DHCP to static and entering all my info. No luck. I've also switched my dns1 to 8.8.8.8 and dns2 to 8.8.4.4, and my WiFi router is set to 2.4ghz only. No success in resolving the issue. Currently my phone will show the "internet may not be available" with the added exclaimation point for a few minutes when first connected, then the exclaimation goes away and I'll have regular full speed internet for around 25-45 seconds before it goes back to a non-internet state. Any suggestions?

Try changing in your router the security setting. If your using WPA2 AES/TKIP, change to just WPA2 TKIP and see if this works for you...
I was having the same exact issue for months. I changed to TKIP only and have been rock solid ever since. No more ! at all... I'm gonna switch to just AES today and see how that works.

Changed to WPA2-AES and within the hour had ! back and no internet. Went back to TKIP and rock solid again. Looks like a possible bug with AES to me. Sticking with wpa2-tkip setting for now.

I'm having this same exact issue.
Anyone who knows what to look for to fix this, what info or files do you need from me? I'm at the end of my tether with this ****

I am having the exact same issue on my galaxy tab s2, even on the replacement. Due to the being such an intermittent problem, it wouldn't do it when Samsung support checked it out...
This happens on both 2.4 ghz and 5 ghz frequency for me. I've tried downloading a wifi fixer, I've reset network settings, and turned off nearby device scanning. I've also tried doing what a forum suggested by changing the ip settings from dhcp to static but it wouldn't connect to wifi at all. Not sure what else to try...
I read that it may be due to nougat 7.0 software. I was suggested by Samsung to first put the tablet on safe mode (this disables third party apps, and would reveil if an app was causing the problem) but the problem still persists. Also did a hard reset on the first tablet I had but it still done the same problem...

I always thought that this was a is problem in 7.0, and was addressed in 7.1. Hopefully, when the next major update comes out, this issue will be resolved.

Oh come on Samsung!
It's been 4 months since the first post and still no solution.
And it's a basic wifi connection!
Internet may not be available! = Samsung may not be available

Heya all. First post I guess
Edit: Gah it was the second. I have to controll myself better and not spam.
So I had the same problem and tried more or less all.
My "solution" was to disable the firewall on the router which means some settings/security there was triggered. My guess is that it's the "Smart Network connection" that trigger it if the phone have both poor Wi-Fi and 4G. It then jumps back and forward = firewall detect strange behaviour and block. That's why there are so many strange "fix" related to the router - hidden network - no security - disable 5Ghz and so on.
Can someone please test asap as I have a plan But if it's not this to test

Wi-fi not working

After connecting to 3 different wireless connections and none of then working, I'm concluded that my wifi isn't working.
I go to settings and check wifi on, it finds the network, connects, but I lose my entire data connection for the duration wifi is turned on!
Is anyone else having this problem?
Sent from my Samsung Vibrant
I'm having the same issues with the wifi. I downloaded wifi analyzer to make sure I was on a good channel. Set it to the best channel and my signal strength is 100%. I will be able to connect for a little bit but for some reason it goes in and out, connection unsuccessful, yada yada yada. I messed with all the troubleshooting solutions for my router (dgl-4300) but nothing works. If anyone can reply with a fix or point me in the right direction, that would be greatly appreciated.
Same Issues
Any help is greatly appreciated. Data working fine when on 3G but Wifi = no data. Connection is fine, IP is fine.
UPDATE: It's working again on my home WIFI. Will have to see if it's just an "at work" issue. Hopefully IT can assist.
Same problem with Verizon MiFi
I have had ZERO problems connecting to the Linksys access points we have setup at my home and my office, but recently my work provided me with a Verizon MiFi (as well as an iPad - don't hate ) and I've had MANY issues trying to get my Vibrant to consistently connect to the MiFi.
My iPad, Motorola Droid, and Laptop have no issues connecting to the MiFi.
On my Vibrant I'm running the 2.1 stock ROM with root & the latest ClockWork recovery.
It will "connect" to the MiFi (I use quotes because I can't really tell - it AT LEAST receives an IP). But I'm unable to send and receive data. I can't even browse to the MiFi's internal configuration page .
To FINALLY get it to connect consistently I have to do some kind of random combo toggling the wifi off and back on and then turning the MiFi off and back on and it will EVENTUALLY connect and stay connected with data flowing freely.
I've customized my configuration a little bit on the MiFi so I'm going to reset it back to factory and not change the config to see if it makes a difference - because at lunch I was able to connect to my boss' MiFi with no problem. I'm thinking it may either be the phone or the mifi...
I've connected to about 10 different wireless networks with NO issues, at all. The connectivity is actually much better than my G1/Nexus.
HOWEVER, last night at a bar I was connected to their wifi, strong signal, but I was not able to use Data. I was in a very poor reception area for T-Mobile... don't think that could be an issue, bit the other places I use wi-fi that is not the case.
I just chalked it up as a fluke and moved on. Not sure what was wrong.
I had this happen to me today. I just rebooted and it went away. Toggling wifi didn't help, but I only tried it once. The phone reboots so quick I figured I'd give it a try.
I have set the phone up manually with static ip. Seems like its a problem with the dhcp.

Major WiFi connection issue

Hi
I've had a search in the forums but haven't seen any other posts re. this but wondered if anyone had any ideas?!
Basically I'm having problems connecting to some networks with my Tab 10.1 (stock, updated OTA to the latest TouchWiz UX last week).
I first had a problem last week when I took the device into work - there's an 802.1x EAP network there but it wouldn't even show up in the network list. My SGS2 connects to it without an issue.
Then when I got home tonight (after happily using it at my parents' house during the day) I found it wouldn't connect to my home WiFi (hidden SSID, WPA2). It had connected to this network fine in the past, but now was just sitting showing it as 'not in range' network. At first I thought it might be a router issue (it used to be a little flaky), but then I saw that my iPod and SGS2 were both connecting and working on it without a hitch.
I couldn't see the network at all in WiFi Analyzer (similarly to at work), although it was showing my neighbours' WiFi networks fine. I tried deleting the saved entry and telling the router to broadcast the SSID but it still wouldn't work.
I then put on my WiFi hotspot on my SGS2 (also a previously remembered connection) and it worked absolutely fine!
Does anyone have any ideas where to go next apart from doing a full reset? (which although not the end of the world would be quite a pain).
Thanks for any suggestions/tips!
OK, bit the bullet and restore my device to factory settings - it STILL can't see my home WiFi, despite my SGS2, laptop and iPod all connecting to it fine. It is however showing up two networks belonging to neighbours and also my SGS2 if I put it in WiFi hotspot mode!
Any suggestions folks??
Sounds like a route issue, did you reboot the router? Is the router on a channel below 12?
Hi thanks for the reply!
I actually just spotted a post at http://www.thegalaxytabforum.com/index.php?/topic/5511-my-wifi-no-longer-works/ with the same issue.
It looks like Samsung have mucked something up when they made the Touchwiz UX update - it now blocks WiFi channels 12 upwards, when the old stock Honeycomb firmware didn't do this. I'd moved my router onto 13 to reduce congestion and I guess the work one must be on 12/13 too.
I can see from the table at http://en.wikipedia.org/wiki/List_of_WLAN_channels that 12/13 are only allowed under low-power conditions in the USA, but this isn't the case elsewhere so they shouldn't have locked it down outside of the USA.
This also happend to me

As I had setup an additional router in my house (with assigned a high numbered -or so i thought- fixed IP address) for some reason my main router tryied unseccesfully to assign the same IP to my SGT as the router. This had obviously conflicts and could not log in.
Went into the router eliminated the fixed IP address and voilá! it got working again, all IP a dinamic!!

G2 Verizon - Wifi Won't Connect

Has anyone had any issues connecting to Wifi networks on their G2s? I got the verizon version on Saturday and haven't been able to get the phone working on 2 different wifi networks. I can connect to the wifi network just fine, but I can't access the internet at all. I can confirm that other devices are able to connect no problem.
Curious if anyone has some thoughts on how to potentially fix this. If not, will be heading back to Verizon to get a new one. Thanks in advance for the help.

I have the AT&T G2 version , it will connect to any wireless router but the connection will last 5 seconds then no internet, this is totally unacceptable I upgraded from the G-Pro and may go back as that never had this issue, I did read LG had a similar problem with the Nexus 4 and Optimus G
Mine works fine. I have a VZW G2 and an ATT G2 connected on the same router. It connects to both G and N networks.
No issues with my Verizon G2.

Did you try rebooting your router? I see this at home with the families iOS devices a lot, especially after heavy data traffic. I'll turn off the router for a couple hours or overnight and the next day all is well. Router is open, no encryption.

I have the exact same problem. It will sometimes transfer some data using browsers, but nothing on facebook, pandora, or the play store it will say connection lost or not data connection.
My wife has the same phone and it works no problem and also the laptop. Must be a dud wifi radio or something like that. Mine is going back to the store tomorrow.

Are you trying to use adblock by any chance? I was and it was causing the same issue you have. I uninstalled it and changed my proxy settings back to none and wifi is working great now.
Just received my LG G2 White brand new from T-Mobile about 2 hours ago. After many attempts to troubleshoot the issue it all failed. The problem is Wifi will connect to router and even work but after 30 seconds the connection goes down. The actual Wifi signal shows connected but no internet it gets stock. We tried resetting the phone and toggling with different features but still it did the same thing. T-Mobile is the worst they were trying to have me ship the phone back and leave me phone less for days. I complained and they are sending another one overnight but have charged me for the phone on my account. Mind you I've had months of bad service, after all I think I got a defective phone. I've read some other people having the same issue with other carriers. If I get another one with the same issue I'm jumping boat. If anyone knows of a work around let me know. I tried 2 different routers same issues connects then it randomly disconnects and stops downloading or transferring data.
Reset Phone - didn't work
Turned off mobile data - didn't work
Turned off wifi sleep - didn't work
I'm on Verizon. I have trouble with initial connection to wi-fi. It says obtaining IP address for a very long time. Even if I have a very strong signal. It takes about five minutes. It eventually connects and works fine. Then next time I try to connect to that router it works fine. It's only the first time I try to connect to a new router.
I just got this phone over the weekend and I was also having trouble connecting to my home wifi.
It would stay connected for 30 seconds or a couple of minutes then disconnect however the entire time the status under the Wi-Fi settings page says Connected even though I couldn't access the internet or the admin page of the router. Frustrating. If I turned off the mobile data, the wifi, the phone, the router, or some other unknown combination of events it would then reconnect again for another 30 seconds to a couple of minutes.
I called Verizon, they told me to take the phone back since I was within my 14 days. I did this and was optimistic. Then the new phone immediately experienced the same issue.
I did some more research, changed my router from 20 mhz channel width to auto 20/40 mhz. Not sure why it was set to just 20. I thought that would fix it. Nope.
I tried to set my phone to use a static IP, that didn't work either.
Then last night I tried the WPS Push Button option instead of using a password. This method worked and my phone stayed connected. I haven't had a chance to repeat my steps to verify it works again but wondering how other people are connecting, password, wps push button, wps pin? WPS is not my preferred option due to the security risks but just trying to track down what works and what doesn't.
I am able to connect at work just fine using a password.
I'm having a similar problem - my work network has no problem connecting while my home network almost never works with this phone (~25% of the time, other devices have no problem). Occasionally, resetting the phone or just turning on-and-off WiFi fixes the problem, but more often I just give up and use 4G. Anyway, if anyone finds a solution, please post! This is such a standard feature that should really work out of the box.
In case it helps, my home network uses "WPA/WPA2 PSK" security and my work connects to "802.1x EAP" security - also I'm not adverse to changing the security options if it fixes the problem.
Thanks! Nick
After reading more on this, I've decided this issue is router related not phone related.
I discovered my router reached end of life in April of this year is no longer receiving firmware updates. Newer versions of my router have received multiple updates since then.
I will be buying a new router. I report back on if it works.
I really don't think it is "router related" as all my other devices work as expected with my router. A new router may fix the problem, but I'm pretty sure the phone's WiFi is buggy and not the router..
Sent from my VS980 4G using XDA Premium 4 mobile app
In my situation it really appears to be how my router is handling the connection when I connect with a password since I can connect with limited security.
Does your router have a firmware update available for it? If so, have you applied it?
Received my new to me router yesterday with updated firmware as of 10/7/13.
My phone was connected for a few hours last night and I have not had any problems today. I'll report back if I start experiencing any issues but getting rid of my old, end of life router and replacing it with a newer router worked for me.
I did not buy a brand new router either. I went with a cradlepoint mbr95 which has been on the market for awhile and has already had a few firmware updates.
Check you wireless security settings
Had a similar issue to this and it seemingly was resolved when I moved the wireless router security over from WPA/WPA2 personal to WPA2 personal only. The phone found the WAP and connected right away. I tried to reproduce the behavior but alas I have not been able to do so. Perhaps this will help others.
hi guys
i found the problem
it happens just when you disable auto update in "settings>general>about phone>update center>software update>check automatically"

Note 3 (SM-N900V) won't connect to 5GHz 802.11ac

Hi,
My rooted Verizon Samsung Galaxy Note 3 (SM-N900V) running the stock KitKat 4.4.2 stopped connecting to 5GHz 802.11ac AP's. I first noticed it at a friends house, then again at home. I can connect to 2.4GHz 802.11ac, 802.11n & 802.11g just fine. When I try to connect, it says "Connecting" for a second or two, then drops to "Saved, secure" with no other errors or messages. Once it's saved, pressing "Connect" doesn't seem to do anything.
My home AP is a TP-Link Archer C9 running the latest firmware. The 2.4GHz & 5GHz bands have different SSID's. I read about issues with Samsung devices & 5GHz channels so I tried changing it from auto to 44 to 36 to no avail. Note that both of my Samsung Tab S 8.4's and my wife's Note 3 (same model & OS) along with all my laptops can connect to the 5GHz frequency just fine. I run a separate DHCP server and tried manually removing the entry for my Note 3 to no avail.
In the Wifi Advanced settings, I have "Passpoint" off and "Auto network switch" unchecked.
I also read about disable Wifi Power Saving Mode by dialing *#0011# but dialing that only brings me to a Verizon error message.
I tried using the app Wifi Connection Manager to wipe all the wifi connections (the "Fix Wi-Fi Problems" option) but that didn't help.
Next I'll try to see if I can figure out how to use logcat to get some sort of error message.
After many hours of reading about similar issues, I've run out of options to try short of factory wiping which I'd prefer to avoid. I'd be grateful for any other suggestions.
Thanks!

Next I'll try to see if I can figure out how to use logcat to get some sort of error message.
After many hours of reading about similar issues, I've run out of options to try short of factory wiping which I'd prefer to avoid. I'd be grateful for any other suggestions.
Thanks!

It could simply be a lousy antenna connection or that your 5GHz radio died. I presume you see the 5GHz SSID when searching.. so the radio itself is probably ok.
Take the back off your phone, using s jewlers screwdriver, check the screws around the outside edge on the back if the phone. If any are loose, that can cause reception issues. Do not overtighten! Just make sure they're firm and not loose.

Hi donc113,
Thanks for the reply.
After powering off, I removed the rear cover & battery and made sure all 12 screws were nice and snug but not overtightened. I also loosened and retightened the one next to the SD card slot since some diagrams indicate the wifi antennas are located there. As an aside, do you know what the "L" and "R" labels are next to round buttons on either side of the SD card? I haven't found any documentation on that yet.
Unfortunately, it didn't help. The SSID shows with a strong signal but still won't connect. This might be the issue, though, because the 5GHz SSID drops to no signal every now and then but that's inconsistent.
I'll try to figure out to use logcat to see if I can find an error but let me know if you or anyone else can think of other things to try.
Thanks!

No idea on the buttons, on mine there are are just brown 'fillers' in them.

Ok.. Found the info on the buttons, they are covers for connectors, i presume for testing purposes.

Mine recently had the issue as well (I have an Archer TP-Link C5). After testing wifi and seeing I still used the 5G at work, hard and soft rebooting my Ubiquity Uni-Fi AC AP, and even double checking with the WiFi Analyzer app, I finally went into the router to check if maybe the MAC was no longer registered. Ultimately, I thought to just unbind the phone and re-enable it. I only got as far as to unbind the IP (there is a checkbox in 'IP & MAC Binding' -> 'Binding Settings') and suddenly it connected and is working again. So, if you happen to have bound a static IP to the MAC address, uncheck that box and it magically works again. The IP stays the same between connections so I guess it is not super important.
Just an idea.
EDIT:
Okay, turns out the issue resolves around the fact that you have a conflicting IP address on your network and the phone software decides to disable the connection rather than obtain a new IP. I found the best way to resolve this is to set all my major devices with an address assignment on the network (you can find this under DHCP -> Address Reservation).
So, though related, the above issue turned out only a temporary fix. My phone was trying to get the same IP as my Ubiquity AP despite the MAC binding for the AP.

Galaxy Tab A 8-inch (SM-T350) Wifi/internet issues

Hi everyone!
Recently, I bought my mother a Galaxy Tab A 8-inch device (Model Number SM-T350) and it theres an issue where the device seems to be connected to her Wifi network, but after a while, she is not able to browse the internet or use Viber. The Wifi Network shows connected. But after a specific time, when she needs to use Viber, she cannot connect to the internet even though the network is connected to her Wifi network.
Its not only Viber, but she cannot browse the internet using Firefox or the native browser.
The only way to resolve this is by turning ON/OFF the Wifi.
We tried a number of things like Setting the Sleep options to Never disconnect from Wifi, resetting the router, and so forth...
I tried updating the device but it seems like that this unit only goes up to Android 6.0..1. There is no security software that I know of installed on the device either. I checked the router settings as well and all devices going through that router are not Blacklisted. So all devices can pass or connect to the network. No MAC address filtering turned ON, it is OFF. But these settings are irrelevant to the issue in question, as the device Wifi shows status as Connected...
This is quite a "PITTY" situation as her Viber contacts cannot even call her either because of this issue.
To recap or to sum it up on the issue, is that after a while the internet does not seem to work on the device even though its connected to her Wifi network.
My mother does not have any other devices at her home.
I wonder if this is an Android bug or there is an issue with our router?
The router in question is a Cisco WRVS4400N if this helps.
Thanks
Bump. I have the same issue with my Tab A 6.

How old is there router
I have a similar problem with the Samsung Galaxy tablet a. My version is SM-T350. When I 1st got it a few years ago, everything worked great and I was able to connect to the Wi-Fi no problem. However, I believe that was after an update, the tab A will no longer connect to the Internet in less it is sitting right next to the router. Even this can be sketchy. It has to be within 2" to connect. I don't think it has anything to do with the router, but something with the internal Wi-Fi. I was thinking before when I wouldn't be able to connect it I had to select WEP instead of WPA
