Problem on wifi - Samsung Galaxy S7 Edge Questions and Answers

Hello everybody!!
I have a problem with my S7 edge...
When i turn on the wifi my S7 edge connect to my wifi and after 1minutes my phone lose the wifi...And after 5-10seconde my phone find the wifi
When i go to the menu wifi i see on my wifi" Internet not available"
I try on my computer and other phone and the wifi work....
What is the problem??Software problem or hardware problem?
Please don't say me it's a hardware problem
My 4g works good!!
Thank you so much

It could be a problem with your WiFi access point. I know some Broadcom chipsets can crash when certain devices try to connect over 802.11g. If you have a wireless N 5 Ghz radio, you could try to connect to that SSID instead. I have a router that started having constant WiFi crashes when I got my new phone, but I just had to get on the 5 Ghz SSID and it stopped crashing.

Thansk for the answer !! it's work

Does X10 have week signal reception or it's my idea?
When I 'm at home I have different signal sign on my laptop and X10. Sometimes it even disconnect while laptop connection works fine.

ICS WiFi Issue: Possible Fix?

I updated my UK Galaxy Note on Vodafone, yesterday. Immediately encountered a WiFi issue. The connection to my wireless router kept disconnecting then connecting, but sometimes didn't actually even connect. I changed the WiFi frequency band setting (Settings>Wi-Fi>Advanced>Wi-Fi frequency band) from "Auto" to "2.4 GHz only" and this seems to have fixed it. It seems like common sense, but I thought I'd post it anyway as people are having issues with their WiFi on ICS.

I had a similar problem. I have a cisco linsys router.
Anyway I flashed the latest modem LR1 using PC odin (modem.bin) and things seem better so far.....

Changing Wi-Fi frequency band) from "Auto" to "2.4 GHz only" didn't fix it for me. Strangest thing is i have no problem with wifi at work while it doesn't work at home wifi. Notebooks get connected to internet at home with no problems when my Note connects wifi but only connects to internet for few secs after first time it gets connected. Then it loses connection to internet even though it still shows up wifi is connected. Any clue on that ?
I've noticed I've been having 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.
Has anybody got any information about this problem? Been experiencing similar problems?
Thanks!

[Q] WIFI Issue...

Hello all!
I have started having some strange wifi issues with my S4.
It seems different to the "usual" WIFI problem others are having. In their case their wifi keeps not turning on, dropping out etc.
In my case, my wifi is working and the phone keeps being connected to the WIFI; it shows up in the router devices list, i can 192.168.1.XXX the router form the S4, but there is no internet connection...
This started with the MGA firmware, and it happens when I come back home, and the phone logs back into the wifi network. Meanwhile an ipad is connected to the same WIFI net and is happily working without interruptions, which makes me believe the fault is with the S4..
After a half hour or so, the S4 suddenly is happily accessing the internet again.
I even flashed the wifi fix patch but no help....
I have a suspicion it might be a dhcp issue, but I've set the routers to assign the same ip to the S4 everytime.
Any ideas?

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.

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

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
