Question Hotspot not reconnecting after pairing to my car - Google Pixel 6a

Hello everyone. I don't know if anyone is having this kind of issue, but I tried to Google for the answer and it hasn't led me anywhere near an answer. What's happening is this: I'm trying to connect my car's wifi to my phone hotspot for allow the car to go online for maps and stuff. When I connect my car to the phone it works. After just disabling the hotspot and enabling back again the car won't connect automatically to it and I need to put the password back in. With another phone i have this behaviour is not present. Also my other phone connects just fine to the Pixel 6a every time, no issues there. And my car connects to another phone's hotspot just fine reliably every time. I tried looking for MAC randomization, but that option is already disabled by default. Looking into the Android 13 settings for the hotspot I can't find any meaningful setting.
I hope anyone can at least point me into the right direction, thanks!

Do these another phones also have android 13?

No. One it's a Motorola Edge Plus 2022 (Android 12) and the other one is a Huawei P20 Lite (Android 9). Those do not have issues, both connecting to the Pixel hotspot and serving the car with their own hotspots.

I found that there are less hotspot settings in Android 13 compared to Android 12.
Also both my Pixel 6a and the Motorola Edge Plus 2022 have wifi 6 radios and don't have any skins on top of Android that might make work or not work my car.
I was wondering if there's a MAC randomization that can't be disabled on Android 13 when creating an hotspot. That's the only thing I can think might be an issue.

You can easily check this when connected from another phone in its connection settings.
MAC randomization is not relevant when it is not supervised in any way. And it isn't, so the connection should happen. The problem may be at the packet transmission layer. There are different solutions, and perhaps the auto does not cope with new solutions. Do you have the ability to check the firmware date with the auto?

I sure can, but I don't know how fit that into the whole issue. IIRC I updated it not too long ago.

Can't find the firmware version of my car, if that could've made a difference.
Doesn't appear to be any MAC randomization while using the hotspot.

I am getting the same problem whenever i try to connect this to my car.

That shouldn't make a difference, the car should be looking for an SSID, not a BSSID.
In Hotspot settings, have you enabled "Extend compatibility?"

I did, but it didn't change anything. With the option disabled on a Motorola Edge Plus 2022 the car connected anyway and, upon restarting both the car and the hotspot on that phone it picked it up immediately. Which leads me to belive that it's equipped with a 5Ghz wifi. It's a 2021 Toyota Corolla.
I know it shoudn't make a difference, but I can't figure out for the life of me why it refuses to work with my phone. I can't deal with inputting my wifi password each time I hop in the car!

I don't see in the video that any password is needed.
Can you provide a link to the video that explains how to pair with the password?

That's bluetooth pairing. That, at least, works fine. What I'm talking about is wifi connection between the car and the smartphone. The smartphone sets up an hotspot and the car connects to it in order to acess the internet for maps data and apps.
This is the video that shows how to connect to wifi:

[Q] WiFi won't work, no matter what!

Hi,
I've just received my Samsung Focus AT&T Unlocked, everything's look good except WiFi won't work, no matter what I do. I've tried all suggestions posted online..
Did NoDo update
Tried WPA
Tried WPA2
Tried with No Security (Open Network)
Tried the channels 6, 9 and 11
Even reset the Router
Reset the Phone
I'd really appreciate any help, WiFi is a must for me!
Many thanks for your help!
You did NOT provide enough information so we can't help you.
Eg. Does your phone give an error connecting or does it not detect WiFi at all? Does your WiFi works elsewhere such as your office?
Oh sorry.
Phone detects all available networks, but can't join/use them. The error is:
"Connection Unsuccessful - Your phone couldn't reach the WiFi network xyz"
Yes, tried creating a network with my Macbook and joining, but that didn't work either.
Have you tried to connect using Wired connection (when your phone is connected to PC with Zune launched)? I just want to make sure that connecting to internet and getting and IP is not the problem.

Yes, that works. So I turned off 'Data Connection' from settings, connected to PC and opened Zune. I can access internet on the phone, even checked the IP, it seems to be using the PCs connection. Removed the USB cable, and there's no internet.
So yes, that works which confirms that there's physical fault in the phone, just a bug?

I had similar problem with my university wireless connection. After several access with Zune, the problem was fixed. And by the way, it may not be a hardware problem since your device detects the available network.
Perhaps you need to visit a phone shop.

Can you please tell me your router's mode, channel, fragmentation, treshold values. Maybe that'll help.
Anyone? WiFi not working is so annoying!

Try connecting to WiFi at your office or somewhere else.
I also have the Samsung Focus and it won't connect to a certain router no matter how I configuration the router.

Sony Xperia XZ Premium WiFi issue

Is anyone here also experiencing the same problem with me?
I found that from time to time, my XZ Premium losses WiFi connection and can't find any hotspot until I turn on then turn off airplane mode, or just restart.
Here are the screenshots form my S7 edge (SM-G935F) and XZ Premium, they were next to each other and very close to the router.
Please help me, thank you.

are you using 5G? if you are, you need to update the wifi channel and band through your router settings. that's what i did with mine and now i don't have that intermittent wifi connection anymore.

Anyone found a solution for this?
Wifi was spotty before the Android 8 update but now it's almost unusable. Every now and again it will just stop showing wifi connections, toggling wifi on and off might show a connection or 2 but it will either disappear or just say "Disabled" when trying to connect to it. Reboot solves it for a little while.
Usually use 2.4Ghz wifi with a variety of router brands.

Happens here on Android 8 as well, quite annoying to be honest. Sometimes drops the connection for no reason, and then when I click on WiFi settings, it doesn't show any connections till I turn WiFi on and off and even then it'll only show 1 SSID, turning it off for a while longer and then turning it back on brings back the rest of them and then it'll connect, but it's stupid how I have to keep doing this every few hours.
I set my 2.4 and 5 GHz bands to different names and join only the 5 GHz, and I don't get drops. On Oreo rooted.
i have xperia xz premium with Oreo 8.0 I encounter the same problems when I'm connected to my wifi, suddenly the data connection is blocked, and when this happens I have to turn off and on the wifi symbol to restore the connection. I do not understand why this happens. My phone is updated to the 47.1.A.5.51 system with November google patches. My modem is Billion Bipac 7800N
So it seems to be a common issue, anyone know if Sony is aware of it?
Where can we complain? It's their damn top of the range phone and it's most basic function isn't working right.

Do a Google search for WiFi and Oreo and you will see that this is affecting multiple cell phones.
Do they all have the 835 chip in them???
I think it is an Oreo issue.
I have no such problems and I have Oreo and the 835.
Try disabling IPv6 on your router.
This is still OS/firmware issue but this temporally fix the issue

I found the solution:
My network works with two devices:
1 ZTE Router (2.4GHz)
1 D-LINK Repeater (2.4GHz)
In the router my XZ Premium works nicely, in the repeater happen exactly what you said, Connect apperars "no internet" after 1 second and wifi on Smartphone is automatically disabled or wifi stay enabled, but says "disabled" on network.
So.. I checked the wlan settings of the two devices in my network exhaustively item by item and I changed the devices settings about 20 times, I and I found that none of the settings matters (wpa or wep, 5Ghz or 2.4Ghz, Bandwidth 20Mhz or 40Mhz, type of network b / g / n, nor channel 1 to 13) just ignore this.
What REALLY MATTERS is a option in the advanced wlan settings, called "Fragment Threshold" this value was at 500, I changed it to the maximum (2346) and my XZ Premium started the connection instantly. Explaining: increasing this value defined that the packet can be up to 2346 bytes before being fragmented, so we deactivate packet fragmentation, reducing overhead and ensuring the best transmission rate possible, so this option determines the size of the frame.
Put simply: Go to advanced Wlan settings, locate "Fragment Threshold" and change to the highest possible value. That worked for me =)
worked for me
1- turn off wifi in being wifi settings ie where you view your wifi networks
2- select "scanning settings". it will show once you have turned your wifi off
3- turn off wifi and bluetooth scanning
4- go back turn wifi back on and enjoy

Question USB/Bluetooth tethering?

No, not wifi. Apparently I can't do auto wifi tethering in Android 11 (my phone) without root on the phone.
I don't want to have to manually enable hotspot every time I get in the car.
Has anyone figured out a way to get the USB or Bluetooth tethering to work on these units?
My phone says USB tethering enabled. I get the notification in the window shade, but nothing on the unit.
What kind of phone? On my Samsung, I use the Bixby stuff which is like Tasker and Macrodroid. It's built-in so I tried it and works well enough. I have a routine that turns on my Wifi hotspot automatically when the phone connects to my car head unit through Bluetooth. The hotspot automatically shuts of when there have been no device connected for a certain amount of time. I think that's an Android setting.
In another thread, it was suggested that this app was working fine and stable:
Bluetooth Tethering Manager - Apps on Google Play
Sharing the internet connection's never been so easy.
play.google.com
That was for a different head unit. Give it a try and let us know how it works.

Maybe I'm overthinking it then. The hotspot option seems to work on my phone fairly well. I set it to never timeout . Only connect to my cars MAC address.
However when I connect to wifi it turns the hotspot off. So I have to manually re-enable it.
I tried using macrodroid once before to turn hotspot on when Bluetooth connects, but it doesn't seem compatible with Android 11's security setup.. Without root and tasker.
The Bluetooth tether sort of worked initially. Once I got to driving, it kept cutting off and then eventually stopped giving the HU access at all, even though both servers were running on the phone and unit.
The other Bluetooth tether I've tried didn't work at all
@watson540 When I'm modifying the Bixby routine for turning on my phone's hotspot, it doesn't let me do anything with the wifi connection. It thinks they're related somehow and that wifi should be off when the hotspot is on. In any case, I have wifi off on my phone when my head unit is connected to my phone's hotspot. All works fine.

That is default Android (look on Android developer). On a hotspot you create a WiFi hotspot and share via mobile data. That is why you can't use WiFi at the same time.
There are very few phones that really can share the WiFi itself. As such this is logical. If there is WiFi, why can't the other phone connect to that WiFi?
It is designed for places where there is no WiFi, but where at least one phone has mobile data which it can share.
That it works differently on Linux, MacOS, ChromeOS and Windows is something else. These devices mostly don't have mobile data at all as they are not phones.
Yes. A phone only has one wifi chip. It can use it to be a client or a server, but not both at once.
That's why enabling hotspot turns wifi off. Enabling wifi turns hotspot off.
The challenge is.. In Android 11 (without Bixby)... How to enable hotspot through some app. Macrodroid can't do it. The app where you create "flows" isn't capable either. I THINK tasker would do it, but only with root from what I previously read. I can't get root because my bootloader is locked.
That's why I was shooting for Bluetooth or USB tether.
It's frustrating because Bluetooth tether in a baked in option in Android 11,as is USB tether.. But the head unit doesn't recognize it or use it.

Since 4-5 months I have Samsung A52 on Android 11. Macrodroid just works fine with enabling the hotspot when my phone connects to the head unit on bluetooth. No root necessary. Thanks to the mentioning about Bixby a few days ago, I am now doing it with Bixby Routines, using an old unit on the bench as I am still waiting for my new unit for my "new" car.
With regard to bluetooth tethering to this unit. Already in 2015 lbdroid (who goes under at least 5 synonyms) wrote his blutoothTethering apks. It works with installing the app on your phone AND on the unit. See his github and his blogpost. I have used it on my first and second unit, and purely out of laziness I simply used WiFi tethering on my 3rd and 4th unit.
(And yes, blutooth is spelled correct when I refer to his apk).
Okay, so I got USB tethering to work and it's beautiful- but bittersweet...
It ONLY works if you reboot the head unit with the USB cable already plugged in. Once you take the cable out, it won't come back if you plug back in. Only with a reboot does it work
@surfer63 - you're the guru around here. How can a trigger be made to enable this on a plug-in of USB?, Or maybe a constant poll every thirty seconds?

I agree. I believed that it was supposed to work this way where WiFi can't be used while the hotspot is active. However, on my Samsung A51, I can have WiFi and/or mobile data active at the same time as my hotspot. I turn off mobile data and while my phone is connected to my home router through WiFi, I can create a WiFi hotspot. When I've done this, I can still access the internet and my home network from my phone. I have to connect to my 2.4MHz band in order for it to work as a hotspot on my head unit. If I'm connected to the 5MHz band, my phone shows a warning that some clients, that don't support 5MHz, may not be able to connect to the hotspot.
Having the WiFi active while the hotspot is active only causes an issue for me when I'm connected to my home access point. I have a VPN server running on my home router/network. When I VPN from my phone to my home with the WiFi on, I can't access the internet or my home network. I think the routing gets all messed up. In any case, it's not an issue for me...any longer.
I was trying to set up my head unit to access the internet and my home network through the VPN on my phone. I found out that when you use a hot spot (in Android), you cannot access the VPN and the data does not go through the VPN on the hotspot. I don't know why...it may be an Android or a network thing. So, I set up a VPN client on the head unit instead and it connects to my home network fine through the phone hot spot. Now, I just have to figure out how to automatically set up the VPN client on the head unit to automatically connect when it is started and possibly exclude some apps so that the data for those don't go through the VPN.

I never looked into lbroid's code for this blutooth apk, but I suppose it should be possible to add some code to check on the "USB device connected" event, and use that to initialize again. (It would of course also require the request for authorization for that USB event).
Or as a workaround: try it from the other side. Install MacroDroid on your unit. Check if a USB device gets connected and at the same time you have BT connection with your phone, and then start the apk on your unit.
Edit: This might require to first stop the app (if running), pause for a few seconds, and then start the app.

Sorry. You put me totally on the wrong track.
I simply overlooked you were taliking about USB-tethering. The previous posts were about Bluetooth tetering.
So my answer might still be interesting for those who want Bluetooth tetering: See also my github where I rebuilt lbdroid's version (nov 2019) with an apk in the releases section.
Nothing creative. Just a copy with an extended readme.

I'll take either/or
It appears that my phone doesn't start USB tethering until I unlock it anyway. So it may HAVE to be Bluetooth... which is fine
I did try macrodroid on the HU to try and trigger the USB tether action.
I looked into the logcat and saw some tethering events going on when I plugged the cable in. They get shut down for whatever reason.
I was able to bring the usb0 interface up with a simple ifconfig command in terminal, but no way to assign it an ip and routing (dhcpcd or dhclient) -- Android is just so far removed from Linux anymore, it's all handled in JAVA now, so I can't just write a shell script
I'll look into the Bluetooth method again

It looks promising. Doesn't work on this unit though.
I assume it's because fyt 7862 actually has 2 Bluetooth chips, and the first one is disabled. I guess it's spotty? I reckon the app is trying to attach to the primary Bluetooth, which is disabled through the rom?

getDefaultAdapter has been deprecated since jellybean. I'd plug in the appropriate call, but I'm assuming that would just be the beginning of a whole host of other things to rewrite as well.

It was built for Android 5/6.
Since Android 7 and 8, many things have changed. In the access rights area, in the "run as a service" area, etcetera. It might require a complete rewrite.

I've seen it in my convoluted perusing. If you look on 4pda, people there talk about activating one or the other in build.prop or some other system related file.
I've seen what I believe is it in the Android settings (the real settings). It's named "carbt". I managed to connect my phone to it once. I never checked any hardwire IDs to verify it was indeed different, but I swear I've seen it mentioned over there. It's up to 384 pages now, so it's hard to keep up

I just bought a Lenovo M10 3rd gen Tab for my work, on Android 12. The purpose is to create a mobile hotspot, for a sonometer to connect on, in order to be configured.
Problem is that there is no hotspot option in the network configuration.
I also bought a Samsung Tab 7 for my son, Android 12 too, and there is no option for this neither.
As both are version without 4G, it could be considered normal, as you won't have anything to share in the most common usage. But in my case, i just need both devices to connect together, without internet.
I then tried with an old Asus Zen Pad, on Android 5. The option is there and it works well. The devices connect together, and i can access the sonometer web page by browsing to it's IP address.
Then, it seem that the option has been removed since an Android version between 5 and 12.
Did someone face this ? Is there a trick ?

Thanks for your answer.
I tried this kind of app. All had a strange behavior. Some didn't work at all, some other created a network without letting me change the SSID, and/or won't allow connection.
One of them (i don't remember witch one) didn't allow some features arguing that i'm not root. And I don't know how to root this tab...

Since there are two versions for the Lenovo Tab M10 Plus (3rd Gen), Wi-fi only and LTE, then perhaps the manufacturer may have deliberately removed the ability to set up a hotspot. Try connecting some cheap Ethernet network card to USB-C, then you should be able to create a hotspot in the apps I provided above.

I bought a USB-C ethernet card from Lenovo. It's not recognized.

Have you asked the vendor or Leonovo support about the possibility of connecting an ethernet adapter to the device?

Yes, they said that this is not possible. Even if a grayed ethernet configuration is present in the network configuration menu.
I also tried with an other adapter is use with my macbook, but it doesn't work neither.

That is, we have a solution:
On the Lenovo Tab M10 Plus (3rd Gen) tablet with Mediatek MT6769V/CU Helio G80 (12 nm) processor - (Wi-Fi only model) it is not possible to run a wifi hotspot.
Please change the title of the thread, which suggests that it applies to all devices, which is not true.

Since it is known that something does not work and will not work, there is also a solution.

It looks more like a surrender than a solution.

Is your ethernet adapter in it also not working?
According to >this< specification, it has native Wi-Fi Tethering.

No surrender. You will not make a lion out of a cat.
It is common and normal for a manufacturer to block some features in a cheaper variant in order to sell a variant with full functionality (more expensive). The customer has a choice before buying.

The ethernet adapter seems to work, but there is still no option to create a wifi hotspot.

That's how you share your internet connexion from wifi to an other device via ethernet. This is not what i need here.
My need is to create a wifi hotspot where other devices can connect. No one will have access to the internet, but i don't need it.

"Mobile hotspot
Mobile hotspot uses your data plan to create a Wi-Fi network that can be used by multiple devices.
1.
From Settings, tap Connections > Mobile hotspot and tethering > Mobile hotspot.
2.
Tap to turn on Mobile hotspot.
3.
On the devices you want to connect, activate Wi-Fi and select your device’s Mobile hotspot. Enter the Mobile hotspot password to connect.
•
Connected devices are listed under the heading Connected devices."
On the second screen, mobile hotspot : That's exactly what i need. But i don't see that option on my tablet. Probably because it's not a LTE one.
It's the same on the Lenovo. The option exists on the LTE version, but hidden on the wifi only version

Internet WiFi Problem

my chinese tablet with almost stock distribution of android 9 , when it connects to my wifi, it says that the internet is not available, when all the other android and non-android devices connect serenely. This problem only does this tablet on this wifi, it doesn't happen if I connect to different wifi.
Thanks in advance for your attempts to help.

Mismatch in wifi connectivity system. Look for advanced wifi settings, if any, and experiment.
However, much more depends on the router's capabilities. If you don't have access to it, there's nothing you can do about it.
1. Have you tried 'Forget the network' on your tablet?
2. If the issue still exists, you should check the settings of your wireless router. As far as I know, a router may block a device via its mac address.
