Android Auto using WiFi - Samsung Galaxy Note 20 Ultra Questions & Answers

I am using my Note 20 with my Android Auto WiFi. I am having a unique issue / warning upon connecting to my head unit. When I connect to my head unit I get the warning from my phone, "Internet may not be available......." and I have 2 options, either Keep Wi-Fi connection or Disconnect.
Obviously if I disconnect then I am no longer connected to my cars head unit.
If I click keep connection that is where it gets weird. Under Advanced WiFi I DO have switch to mobile data turned on, I also DO have Mobile data on and my head unit DOES show up under Network exceptions.........
All the above SOUNDS like it would be the right thing.... HOWEVER, when I do that, I have NO DATA at all and obviously it does NOT work.
IF when the warning comes up i just IGNORE it or hit the HOME button and it goes away. WiFi stays connected, DATA stays connected and EVERYTHING works RIGHT!!!! However.... I am tired of having to do that every time I connect. I am sure there is something that I am missing, so I figured that I would ask the smart people. Thanks in advance.

Do you have tethering on?

Nope, no tethering on

Problems with BT, AS, and WiFi while connected to 3G

I've been triying to figure this out for awhile but here's the basics of what's going on:
I have a Japanese HTC Touch Pro, (and yes EVERYTHING is in Japanese, but this doesn't really bother me.) We don't have MMS over here, so we use a constant 3G connection and mopera U to push email to the phone.
So, when i'm in my Comm Manager I have a Data connection on as well as the phone connection.
If I try to turn on my WiFi it will turn off after 3 seconds (just enables it and disables it)
If I try to use my bluetooth connection, same thing (enables BT, then turns it off again)
If I connect my phone to my PC via USB it will try to connect at first, but will suddenly disconnect after a few seconds.
Well, I figgured out that Active Sync won't allow the connection while the phone portion is turned on. Easy enough, I turn my phone into flight mode and it connects just fine and syncs. While this is a tad retarded, I will accept it.
However, In order to get bluetooth to work, i need to disable the 3G connection. Now.. here's what I don't like:
I *HAVE* to have my data connection for email/internet or anything. But, the phone will only seem to allow either the Data connection through the 3G OR bluetooth/wifi, not both.
Now, if I have BT enabled first, then try to establish the data connection I get an error telling me it cannot connect to the 3G network, same effect though, it will try.. just won't allow it.
What really makes me mad is i'm not wanting to have it networked to anything, I just wanna pair it with a headset so I can listen to the mp3 player while on the train and send out emails from my phone.
I tried calling HTC (good help that was) about it, and they suggested hard reseting the phone, soft reset, ect ect.. There's not really a problem, i'm sure there's just a setting somewhere to allow the multiple connections at one.
Does anyone know of any tricks or ANYTHING I can do so I can use my phone the way it was intended?
Did you ever find an answer to this? I am having a similar problem with my Fuze. When bluetooth is enabled, eventually the phone begins to refuse to open a data connection. :-(
No, i never found an answer. I'm not tech savvy enough to find it out.
But its REALLY annoying. I just want to use my USB headset, not connect bluetooth to any network or route messages that way.
Not sure if this is the fix to your problem, but this helped me when Wifi kept turning off, its a setting in WinMoDevCenter, it stops all data connections when connected to sync
in WinMoDevCentre go to Mobile Device settings -> Connection Settings -> Allow Data connections (last check box)
after that i was able to use wifi while plugged in just fine

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.

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.

tethering problem, wifi connection constantly going on and off

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.

Androud 7.0 Bluetooth Keeps Disconnecting - How To Fix?

LG G6 on Android 7.0 ( I suspect this issue is not specific to this phone.) This happened to me like a year ago. Bluetooth in my car kept disconnecting and it had to do with me turning on some sort of feature where the phone keeps scanning for nearby Wi-Fi networks to notify me about. Of course as you drive your car around it periodically picks up a strong enough (nearby) networks. But I think it was doing it even without notifying me on the screen. Anyway, the setting was sort of buried but I eventually found where to turn it off and the bluetooth disconnect stopped.
So I replaced my phone with a new G6 because I switched providers from a GSM to a CDMA provider. I restored my apps and everything was working but then something changed and it started happening again. So I backed up the apps, factory reset, and restored just my bare minimum apps. Worked fine again. I didn't really add any apps that would affect this type of thing and then today I went for a walk and listened to an Audible book for about 45 min. Returned back and disconnected the headphone. About an hour later reconnected them and started listening to music and it started happening again. I have Wi-Fi Notification and Show Wi-Fi popup disabled in Advanced Wi-Fi and when this was happening driving around I can confirm Wi-Fi was turned off (I have a Llama event that automatically turned Wi-Fi off when I connect to my care Bluetooth)
Any ideas what is causing this issue?
I believe I determined the problem. I have a Pebble 2 watch. It was disconnected and while playing music over bluetooth, I went to reconnect it and for the first time I saw some message about allowing the app to turn on bluetooth (even though it was already on.) I enabled it and immediately lost my speaker bluetooth connection. So my guess is my watch app was repeatedly trying to connect to the watch every couple of minutes or so and each time that is what would cause the other bluetooth connection to disconnect. Maybe if I go into the watch app permissions and disable bluetooth toggle permissions that will prevent it from doing it when the watch is disconnected.

Wi-Fi dies when using bluetooth to listen to audio?

This is my second phone to have this problem. First was my old S4, now my S7 has the same problem. Basically, I want to watch YouTube or Netflix on my phone over Wi-Fi, and I want to listen to it on a bluetooth headset. But after a few minutes of watching/listening, my Wi-Fi connection always dies, I get that little exclamation point next to the Wi-Fi symbol in my notification panel, and the only way to fix it is to turn off Wi-Fi and turn it back on. It'll work for another couple minutes, then die again and need to be reset. Bluetooth stays connected the whole time and never drops. It's just the Wi-Fi that gets dropped. If I turn Bluetooth off and just listen via phone speaker or wired headphones, no problem, Wi-Fi can cruise all day.
The research I've done suggested that 2.4GHz might be causing a problem, but my network is 5GHz. Another suggestion was to switch the phone to a static IP address, that didn't help. I'd also read that Android has problems with IPv6, so I went to disable that in my router and discovered that it's never been on.
So, I found three solutions on my own, and none of them worked. Now it's time to reach out to the brain trust here. Does anyone have any idea what might be the problem? Vanilla S7, no root or ROMs. Thanks!

Have you tried the usual first step in troubleshooting, have you tried booting to recovery and wiping the cache partition?
You can also try flashing the stock firmware for your model number via Odin.
