S8 Internet connection may not be available issue

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.

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

Autoconnecting to cellular phone Wifi

My android head unit doesn't seem to be able to autouconnect to wifi. Here is my settings:
I use an iPhone iOS 13.1 with bluetooth connection. That works fine as its autoconnects when turning on the head unit. To engagen the phones Wifi I have to toggle the "hot spot on /off " on the phone as the head unit will not fint it otherwise.
As I understand the Iphone doesn't seem to be able to connect as the hot spot setting changes to off in the same time the Iphone autoconnects to a Wifi-network.
Any workarounds?
Im thankful for all suggestions.
Greetings from Sweden

From what I understand, an iPhone needs to be on the WiFi Hotspot screen to be able to allow other devices to connect.
I'm sure it's a security thing. However, it is annoying if you're trying to use the device as a hotspot. Android doesn't behave in this way.
I'm not an iPhone expert so maybe others will have another idea. My thought is to either purchase a dedicated hotspot (they make some that are also OBD readers, offer keyless entry, etc) or switch to an Android device.

iMars Model: A75789 (8227L) WiFi Random Mac Address?

Hi All, I recently bought an iMars A75789 (8227L) from Banggood, All works fine so far except the WiFi has an issue, the MAC address changes every time the head unit is power cycled, the first 3 out of 6 sets of double characters seem to remain the same while the rest changes on power cycle, has anyone had the same issue and been able to fix it or somehow turn off MAC Address Randomization? would be grateful for any help as its a pain to try and tether my phone using it as a WiFi hotspot and entering the mac address every time.
Thankyou.
Video showing mac address changes: https://youtu.be/DqrkLLvzKvQ

Hi, I have the same issue with this variant from Aliexpress. I have inquire help and they replied that they can't change this. I have searched everywhere and it seems this is something implemented in the OS and there is no option to turn this off. It appears that since Android 8, integrator's and implement the random mac address to their devices. this feature make it safer for devices when they are connected to publics WIFI by being hard to trace.
This was a issue for me because I am controlling the internet access with Circle and brought up an new device each time my car was starting and then return home. So It brings a list of a tons of the same device with different mac address.
what I have done is to add an older router in my garage with a different WIFI and keep mu head unit insulated to my controlled WIFI. since then no more WIFI spoofing!

WiFi Connected No Internet

Hi,
I have a Eincar head unit and it was working perfectly fine. Yesterday I turned it on and I can't connect to the internet. It says it's connected to my wifi hotspot but no internet. I've tried everything and still nothing. It's not my hotspot because I'm within reach of my home wifi network and I still get no internet. Also do you know of any modded firmware I could use on my unit?
QuadCore-R16
6.0.1
5.3.19-7-42-656201-170225
v7.3.1_20170113.134439_YHT1
Thanks,

New scenario
Today when I went to turn on the EINCR 10" display unit in my other car I have the same thing, it says "connected no internet". What are the odds it happens to 2 different radios and nothing has changed on my hotspot or router.
It's weird that I can download from the play store and use Pandora.
Anybody else experience this?

Have you found out what to do?

Why not connect via Bluetooth to internet? Is for me the better approach.

Android stereo WiFi issues.

Hi after much reading and searching I have still not come up with a proper answer and was wondering if anybody here may be able to help me? My issue is WiFi connection on my xtrons headunit (probably been discussed a million times) I have been able to use WiFi both with 4G google and tethered to iPhone but this will only work maybe 1/100 times, now the unit will show many networks but neither my phone or dongle?? So therefore I cannot connect?
When my networks are shown it just cycles between connecting and authenticating and will not connect.
If I reboot everything it may connect once but then back to same problem. Such a shame as the unit is best used with full internet connection. As I say when it has connected it has been great but only works for short period then will show networks but will not connect. Any help would be amazing. Thanks in advance.
