tethering problem, wifi connection constantly going on and off - Samsung Galaxy S8+ Questions & Answers

My work network went down earlier so i thought i would just tether the laptop to my S8 over wifi and use my 4g connection instead. But the laptop constantly connects then disconnects about 2 seconds later, over and over again (I can see it in the hotspot settings on the phone thta it appears as a connected device then vanishes immediately after). Tried turning hotspot on and off again on the phone, made no difference. Normal wifi use on my phone seems ok, its just this wifi hotspot that doesnt seem to work properly. Using exynos version on AQDD.

I'm having the same problem tethering my s8 to my android head unit. I connected to my tv box just fine, but I see the same cycle as you when I try to connect to my HU. I previously connected my S6 to the HU with no issues. The only thing I can think of is I used Smart Switch to copy everything from my S6 to S8 and it copied tethering settings as well and maybe that messed something up. I've changed the network name and password but that didn't help.

I finally got mine to work. I changed the security setting to open, and it connected. I then turned on only allowed devices and added the mac address of the head unit.

G1 won't connect to wifi

So I just rooted my phone today at my friend's house, I used his wifi just fine, no hickups. I don't have a service plan at the moment, so the only way I'm even using it is over wifi. Well when I got home, I tried connecting to my wpa2 secured network and I can't connect. What happens is the phone recognizes my network, I put in the passkey and it just sits and does nothing. I connected to it before I rooted my phone (and then this started happening once I changed some settings, but I figured it'd be a moot issue once I rooted.)
So far I can't get it to connect.
Any ideas as to what's going on?

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

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.

I had similar issue with my aTab Phone 4 and TP-Link TL-WR941ND (OpenWRT)
After disabling WMM capability in the router the problem disappeared!

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.

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.

Oneplus one: Connected but, no internet

Hello everybody,
I am using an oneplus one running cm-13.0-20160316-SNAPSHOT-ZNH0EAO1QB-bacon and the kernel provided by cyanogen, and I am using xposed. My wifi had been working fine all day but when I went to work and got back I had the following problems: It would connect just fine but there would be an exclamation mark besides the wifi-logo on the statusbar. And inside the wifi-settings there would be text under the wifi I was connected with, stating: Connected, but no internet. This is what I tried up untill now:
-Turning modem/router on and off
-"Rebooting" my TP-link modem using their website
-Switching to cm-nightlies
-Switched to an older lollipop backup
-After that I dirty-flashed the stable cm13 release without installing xposed
I heard some people on the internet saying that there could be a problem with my kernel, but I haven't tried anything with that yet. My worst fear is that it would be a hardware problem related to the fact that I led my phone fall about two months ago. My screen had to be replaced but the sim-tray is still broken. I still need to replace that. Also the grill that is on the top off the top bezel of the phone went off, I think that it's the mic for calls, but I don't know for sure. I am really anxious about this, please help me.
UPDATE;
This seems to be a problem related to my home wifi, because other wifi's work just fine. Too bad that my knowledge in this field is very lacking...
Did you finally find a solution? I have the same problem, only at home and only with my phone (no problem with my computer)...
go into you router settings and change your wireless setting to the following:
wireless channel - 10
wireless mode - 802.11 b/g/n
if the above wireless mode dont work, try the other modes. usually this is set at auto and may confuse wifi on phones
I'm having the exact same problem. WiFi at home works great with PC+Win10, but I can't manage to make it work on the OPO.
It says "connected with no internet" or "connected" but then I can't navigate, and also the device appear as not connected on the router admin page.
WiFi on the OPO works fine at work or other places. I really have no idea why this is happening. I'll try to flash an update.

Portable hotspot issues with car wifi

Hi,
I've joined this forum to try and get some help with this along with any future issues as it looks like there's a smart bunch of people on here...
Please do move this to the appropriate area if I've put it in the wrong place.
I have a Samsung Galaxy S7 on a UK 'Three' contract.
However I recently bought a new car which has a WLAN feature - basically what it does is connects to your phone's portable hotspot, then broadcasts that internet connection on it's own in-car hotspot for passengers to connect to.
The benefit (because at first glance you think "why bother - why not just connect those devices straight to the phone's hotspot?") is that once the car connects to your phone's hotspot it uses the car's antenna to receive data etc which means you get a stronger and more consistent data connection.
So, the issue:
My portable hotspot works fine when connecting a device such as laptop/iPad etc directly to the phone.
However when I connect the car to my personal hotspot, and then a device to the car, it all connects up okay but I get errors on the end-user device saying that there's no internet connection.
I have done quite a lot of testing with this - for example in the following situations it works perfectly for the end-user devices - just never with my S7!!
- Connecting the car to my girlfriend's iPhone SE hotspot (on the same network)
- Connecting the car to my friend's S7 (on the same network?!!)**
- Connecting the car to my home WiFi whilst on the drive
**Interestingly, my friend's S7 was bought separately so had a pure Samsung build on it - mine came from Three so had a load of Three crap on it.
So, to tackle that, yesterday I did a cache wipe and factory data reset, then entered download mode and using Odin, loaded on the latest version of Nougat including all the new BL/AP/CP/CSC files.
Then me and my friend swapped SIM cards to see if that could be the issue, we tried using both phones. None of it worked, and now even his phone with his SIM card in it (which previously worked) no longer works with the car's WLAN.
It still doesn't work and it's driving me mad
Today I'm going to try messing with APN settings because I've read that changing the APN type to just "default" has solved some similar issues to this but without the 'middle-man' car in the middle.
I've also called Three and asked them to send me a replacement SIM card.
I'm sure it is NOT the car that's the issue, as it has worked fine on some devices.
I'm sure it is NOT the Three network that's the issue, as it has worked on 2 other devices on that network.
I suspect it's either some sort of config that needs changing, or the hardware of the phone is faulty.
I have a "remote management session" with Samsung support later today, but I don't expect them to be able to help with this remotely
Any thoughts or ideas here would be greatly appreciated, I'm sorry I've written so much but wanted to include all the info.
Thanks, Andrew

Hotspot connects but no internet on other device

Anyone else experience this? I'm using Straight Talk/Verizon SIM. Trying to connect an S7 to setup as backup phone, cannot get any internet etc. Works fine when on home wifi. Do I need to root and edit my buildprop? Straight Talk allows tethering
I have/had this this issue with my joying Android car deck and my 6t, and now my 7pro.. So if I just turn on hotspot, and connect to the deck, it showed as connected, but isn't actually.. 6t was the same way, but on the deck, in wifi settings if I turn wifi off, and allow it to reconnect to the 7pro, it will then work.. that's the process for me every time.. but it only will connect if I let it try once, turn that wifi off on the device I'm trying to connect to, and then turn wifi back in. I leave the 7pro hotspot on the entire time.
