Tethering wifi will not work after updating (ota) android 7 - Galaxy S6 Q&A, Help & Troubleshooting

Hi,
I suggest that before the update worked perfectly.
After updating the wifi tethering does not work anymore.
In practice, the other device connects but does not navigate.
I noticed that with tethering connected and connected device if I disconnect the data and reconnect them, the connected device navigates but no longer surf the phone.
To be able to surf the phone I have to disable the router and disconnect and reconnect the data.
It's as if either surfing one or the other.
I have already reset my factory data.
My sim has no tethering block.
I've already tried to change APN (default - default,dun - default,supl,dun).
The same problem also in safe mode.
Can someone help me?
Thanks

Nobody? :crying:

Data Connection is still used when connected to WiFi!

I've just been charged £400 by Orange for exceeding my Data limit of 1GB , watching You tube video's but whilst connected to WiFi.
I did a few tests using www.showip.net and found that when you connect to WiFi your connection is still rooted through your data connection, so your download limit is being sucked away when you are thinking your safe as your connected to your WiFi connection.
You actually have to manually disconnect your data connection, then connect to WiFi, your data connection doesn't automatically disable itself when you connect to WiFi.
This seems like a major bug to me and I can't see this documented by HTC or Windows Mobile
Is this a know "issue" and is there a fix?
Regards
You do not need to pay them anything,just go to your local citizens advise bureau or trading standards..
In order to prevent using 'data' connection you have to disable it with a third party app ,such as data disconnect,even then you have to manually disable it in the connections centre,if you disable it in the connections centre and do not use an app such as 'data disconnect' it will still connect..
Therefore it is a fault with the device..
Sorry to bump an old thread, but I just discovered this issue. Which app will automatically disable 3G when I'm connected to WiFi? I always thought if you were connected to wifi your data would not get used? Guess I was wrong :S

Install Android Data n wifi works like a charm...
In windows, i've seen Wifi-on-demand once installed,starts the data automatically when wifi is lost,but data stays on even when wifi is reconnected.I guess there is no solution for this yet....

CHTS switches Gprs off, if Wifi is connected. Also you can disable gprs Data totally.
At best you make a home profile, which disable gprs totally and only if you really want to use gprs, you switch to another profile, which allows it.

[Q] wifi not working on GB 2.3.4

I am not able to browse on wifi network. Wifi toggles to on position, can scan the network but not connecting
My phone is running on stock Indian ROM 1.52.720.3 with S-off and rest everything stock, "NOT ROOTED"
Till 2 days back it was working fine and i could use the wifi network
Now most of the time it does not connect to the wifi network, it keeps scanning, detects the network, attempts to connect and finally says disconnected.
Sometimes it connects, i can see the assigned IP but not able to browse the internet or use the android market.
However internet pass through option is working when plugged in USB
I am able to connect my laptop to the wifi network and use the internet, so my network is fine.
I spoke to the customer care, they told me to do a factory reset from Bootloader option...I did the factory reset but still wifi not working
Any help please

I haven't had that issue with the stock ROM, and but it has come up with some modified ROMs. The solution has been to scan for the network, and attempt to connect and then disconnect & forget the network. Rescan and connect worked perfectly after that.
Worth a shot.

Wifi stops working after being left for a while (still connected)

Having an issue with the Tab 2 where you go to pick it up and start browsing after it has been sitting around a while (not sure if the time matters, but it seems like after sitting for most of the day) and the wifi is still connected, but nothing works than needs data. It acts like it would if you had not internet connection. Toggling the wifi off and on will fix the issue and notificaitons and emails start pouring in.
Anyone else have this problem? I found a similar issue on the 7.7 forums but nobody reported a solution and I am not even sure if it would have worked on the Tab 2 anyways. I am thinking about making a script that toggles the wifi automatically if it detects it can't connect to the internet. But that is a little ridiculous needing to do that. It shouldn't be losing connection in the first place.
Hi Pirate
it's a bit depending on the ROM you have installed - but since Android 4 you have a quite reliable setting. The default behavior of Android devices is to deactivate the wifi connection when it goes to sleep.
Some ROMs don't recognize the disconnection and the switch/button still shows "Wifi on" although disconnected.
First step: go to settings / wifi settings, hit the menu button (top right three dots) and check the advanced settings.
Somewhat like "Keep WLAN active in standby" - set this to always.
That should solve it already under android 4.x
If this doesn't help, look into Play Store - search for "wifi keep alive". But for the SGT 2 you shouldn't need it
Greetz - Chris
It was already set to "Always" so I don't think that will help. I will look at that app to see what it does.

wifi turns off when not in use to save battery. I think it might be a default even if you have it set to always on.

The problem is that it never comes back on. Well it shows the wifi icon and the signal and everything but it just doesn't have any data connection. Any apps that use data act like wifi is off. The only way to get it to start working again is to toggle wifi or reboot. I also forgot to mention it is the stock ROM, only rooted. It got the OTA a few days ago too and it has happened since then.
You're not alone

It's the same effing stuff people suggest to every wifi glitch out there.
To people who think it's due to the wifi sleep policy: although I've set it to always, why would wifi not resume, after screen is turned on? It's not the wifi that gets disconnected, it's the internet (or the download speed) that stops working.
To people who suggest it's a power saving feature under low battery conditions: Sorry, I've tested it while charging and with full battery.
To people with the above two arguments: Connection to some routers works perfect with the phone. Like when I turn on the hotspot on another phone, the wifi works great. Also, wifi on the other phone from the same source (laptop used as internet access point) works well.
To people who suggest resetting the router or wifi on phone: The internet does start working again, but only for a few minutes. Even if the screen is turned on, the internet may stop working mid-download.
The actual situation is that the phone disconnects from the internet, but keeps showing a connection to wifi. Like I used connectify hotspot to create an access point, and after a few minutes, the phone moved from "connected clients" list to the "previously connected clients", even as the phone showed connected to wifi with even the download arrows blinking, but no internet (or download speed). This only happens with certain sources (of wifi). And other phones may work well with the same source.
I have tried (several times and in different orders and permutations) the following to no effect:
1. Resetting the router.
2. Resetting the wifi on laptop.
3. Resetting the wifi on phone.
4. Restarting the phone and laptop.
5. Static IPs, gateways and DNSs. (Even though the problem was not with connecting to wifi and even internet works momentarily after resetting wifi).
6. Turning off items controlling wireless network in wireless connection properties.
7. Turning off firewall.
Waiting for a savior.
I know this isn't super helpful but I had the same bug you describe on the previous version of carbon. When I updated to the latest it seems to have stopped.

Same issue. also using connectify and also tried all things you have described. If you find any solution please let me know.
I had the same problem on my Huawei Honor. You need to set static IP in wifi settings (when connecting to AP, press "show advanced settings").
Mine settings were:
IP adress: 192.168.1.75 (make sure other devices are not connected with this IP)
Gateway: 192.168.1.254 (it could be different. Use the same as you're using to connect to your router)
Network prefix length: 24
DNS 1: 8.8.8.8
DNS 2: 4.4.4.4
No option for static IP in connectify

There is no option in connectify for static IP and in USB wifi dongle also there is no option to set static IP.
Help!

1. I have had the exact same issue for (atleast) the past 2 years. Have survived by repeatedly turning wifi on and off.
2. I too use connectify. This issue doesnt seem to happen on every wifi connection (just like your case). Even more specifically, it seems to happen ONLY when I connect my phone to the hotspot created via my laptop (connectify).
3. Even when the internet is actually working, some apps do not seem to recognise that(take some time to realize it is working), while others are able to connect instantly. Specifially, whatsapp is unable to send/receive messages for about 1-2 mins, after which I receive a whole bunch of messages at once.
This does not seem to be an issue due to connectify as well. I have tried creating a hotspot from my laptop without using connectify as well, but unfortunately, nothing changed. Further, this does not happen when my phone connects to a hotspot created via connectify by some other pc. The wifi and internet work perfectly fine when connected to a hotspot created via my friends computer.
Further, this problem happens only when a mobile connects to the hotspot. Doesn't occur when another laptop/PC connects (not sure about tablets).
I have looked into every nook and cranny on the internet, explored every forum for any working solution, but have been unsuccessful. In fact, this is the first place where I saw the exact same problem as mine, and was wondering if you have found any solution to it .

I'm having the exact same prob on my ZTE Grand x V 970
It started when i had kitkat and i couldnt even "fix it" restarting the wifi, i had to reset the phone in order to have my wifi work for like 2-5 mins and then stops recieving data, tried to reconnect and stays on turning on wifi.. Now i changed to the stock Rom and the problem is still there but at least now i can "fix it" restarting the wifi connection until certain point.
Issue sharing internet with Connectify from PC
Go to:
Control Panel\Network and Internet\Network and Sharing Center
On the left column, click on CHANGE ADAPTER SETTINGS.
You should be in: Control Panel\Network and Internet\Network Connections by now.
Then click on: Microsoft Virtual Miniport Adapter and click on Properties, then click on the 'Configure' button in the 'Networking' tab. From this window, go to the 'Power Management' tab and uncheck 'Allow the computer to turn off this device to save power'.
This works for me. Try this out
If this doesn't work further, you can try out mHotspot for the same purpose.
I've had the same issue, with the wifi saying it's connected even though it isn't.
This thread is 4 years old and this issue still hasn't been fixed. What a shame.
Same issue here on OnePlus 3 even after factory reset.
I have this same problem after the security patch Mid March to Jan 1, 2019. The WIFI doesn't show in the top status bar, but toggling wifi off/on fixes it till the next overnight. I did make one change to my wireless about that same time and that was moving the min connect speed from 6Mbps to 12Mbps to help with bandwidth issues being cause by devices using low speeds and having several SSID broadcast. My S7 and Tab A both work fine - so I think it was something in the security patch.

[Q] USB Tethering without data connection

Hi,
Using Android 4.0.4 on an AT&T Samsung Galaxy Note (SGH-I717).
I'm trying to set up a simple network between a computer and the android. This is because the android will access a web page on the computer. Unfortunately I don't have the option of rooting the phone. I've been trying to get USB tethering enabled without a SIM card or wifi connection but it always bugs me with a message "Insert SIM card to access network services". I've tried a couple of apps that try to enable it for you (Tether It, Tasker), but they do not work.
I note that tethering will work if you start with WiFi connected to an access point, enable tethering, then disconnect WiFi, but that's not good enough here because I may not have anything to connect to. I need to just be able to hit a button somewhere and have it work with no data connection.
Is this generally possible (even by writing an app)?
As an alternative, I know I can do a hotspot without data connection via "Hotspot Control", but it does not stay connected reliably (it may drop out after about 2 hours and this must run unattended). I think the unreliability is either the fault of the phone or the app. I haven't found any other hotspot apps that work without data.
I'm also aware that there are USB-powered WiFi routers that can be used but I'd like to look into USB tethering and android hotspots first.
Any ideas?
Thanks

Can't Connect to a Certain Wi-Fi Access Point, but can others

Just bought this Moto G Fast phone today, brand new, and I'm having issues connecting to Wi-Fi. Whenever I attempt to connect to a Xfinity Wi-Fi access point, it attempts to connect and tells me sign-in is required. I get to the screen where I enter in the username and password, but it then disconnects me from the access point, and takes me off the sign-in page before I can enter in the information. This happens in an endless loop. Never staying connected for more than a few seconds before it disconnects and reconnects.
I tried doing a factory reset multiple times.
I tried forgetting all wi-fi networks.
I have tried resetting the wi-fi, Bluetooth, and wireless network settings.
I tried doing a hardware Wi-Fi test, and get the green check mark.
I tried turning off my phone, waiting for thirty seconds, and turning back on my phone with the issue still existing.
I have tried resetting my phone multiple times.
I have removed my SIM card and reinserted it.
I can use my computer to connect to this Xfinity Wi-Fi access point, and then use my computer as Wi-Fi hotspot. My phone is then able to connect to my computer to access Wi-Fi to this Xfinity Wi-Fi hotspot indirectly. It however cannot connect directly to it by itself.
I'm able to connect to other Wi-Fi access points without issues, it's just Xfinity Wi-Fi access point near my home that I can no longer connect to. My computer however is able to connect to this same exact Xfinity Wi-Fi access point without issue. The connection from my computer to the Xfinity Wi-Fi access point is stable, I'm able to watch YouTube videos etc on it. However for whatever reason, sitting at the SAME exact desk my computer is at with my phone, my phone isn't able to maintain a constant connection for more than a few seconds.
I don't have physical access to the router.
Thanks for any help! I have the feeling I should just return the phone, but I don't want to pay the $49 restock fee, and this seems to be a software issue, and not a hardware issue, so I'm not sure anything is wrong with the device from a hardware perspective.
