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

Hello all. I've just purchased a 3G/WAN WI-FI router (TP-Link model TL-MR3420 - link to manufacturer's page). It has an USB port to connect a 3G/4G modem. I tried to connect my P920H (V28b stock ICS - XBSA large partitions) but the router doesn't recognise it. I tried to use an older 3G phone (Sony Ericsson W980) and it works like a charm. In both cases I configured the phones to USB tether with their own configuration options.
Anyone managed to make this work? I believe the router lacks a driver, but I've found no driver for any phone on the manufacturer's page, although I works with the Walkman phone.
Edit: I forgot to mention that all tethering features on my phone works fine. I can turn on my hotspot and I can plug it to a PC's USB port and act like a modem. I just can't do it with my router.
Why I want to do this: Most of you who have nice broadband access may be wondering why I want to use my phone to provide Internet access to my router. Here's why: In the region I live, broadband access is a joke. A miserable 1Mbps insufficcient to watch even the lamest youtube video. But it has no limitations, so it is good for TV upgrades and other connected devices to do their maintenance.
On the other hand, my phone provider has a wonderful coverage around my house, sustaining an average of 3Mbps, reaching 10Mbps late at night. So, when I want a quicker net, like to watch Internet movies or download large files, I used to turn off my router and turn on the phone's hotspot. But even setting its SSID and password identical to the ones on the router, it takes some tweaking on the devices for them to reconnect. It was a nuisance.
With this 3G router, all I would have to do is connect the phone to it and it would switch from WAN to 3G. All I need is a driver that would make it recognize the phone and use it as a modem.
I messed with wifi tethering a bit a while back. Couldn't get it to work. My other phone sees it as a wifi point but won't connect. Something to do with LG not liking tethering I heard. I saw this mod that fixes tethering for some devices but never tried it ( I don't really need tethering). I am curious if it fixes it:

Hello drastic00!
Thank you for your suggestion. I understand that the mod you suggested can have nice effects on slow or even broken tethering.
The problem is that I haven't made myself clear on the first post. I can see it now and I'll edit it right away. The tethering feature on my phone works fine, both WI-FI and USB tethering works. What I need is a USB tethering that makes my router "think" that my phone is actually a 3G USB modem. When I use this feature on a PC, I have to install the drivers. The bad news is that I can't install these drivers on the router.
Okay. I figured if wifi tether isn't working then usb isn't either. So what firmware do you have on which it is working?
There was a small discussion on a thread a month or so ago; it wasn't working for the 4 or so people who posted then...I think we were all on ICS or higher, but not positive. That's when I tried to see if I could get wifi tether to work. I didn't try any usb tethering.
So I guess I am not understanding the advantage of plugging direct to the router. Why not plug the phone to pc (signal in) and the router to pc (signal out)? Because it would be easier to switch from the signal you normally use? This is a new one on me... I have no idea if an ethernet switch would be of use...2 signals in for the router to broadcast and choose which wifi signal on the client end (not sure if your router could do that, just grasping at straws, since I haven't tried anything like this).
It's weird other phones work though, so I am still curious if Crossbreeder mod would do anything. It seems the other phones have a piece of software the O3D does not. Unless the router has drivers installed for those devices by default, which I doubt; you didn't install anything for those to work, they worked out-of-the-box, so to speak, right?
Exactly. Both WIFI and USB tether always worked out of the box for me, with several ROMs, either stock and modded ROMs. Eventualy some modded ROMs did break tether, but usually broke many other things as well Probably too undervolt and/or too overclock among other things I don´t understand.
I remember that discussion about not working tether, but didn´t get involved. It never happened to me. I believe it is more a hardware issue. If it happened to me, the first thing I would do is install the original stock Froyo to be sure if tether didn´t work with the most original firmware.
As to why I want to put my O3D as the Internet provider for my network: I have several devices connected: 3 PCs, 2 Androids, 1 TV and 1 Blu-ray player. The last two are not too easy to make connect to a different WIFI net, even if they have the same SSID and passwords. I used to turn off the router and then turning on the phone´s hotspot. The problem is that almost always several of these devices didn´t realise the switch and kept trying to connect to the unavailable router. The same thing happend when switching from the phone to the router.
Also, I don´t want to buy a 3G modem, because the speed advantage (and low fees) are "connected" to my voice plan. The SIM card is my primary phone number So, I need it to be able to make and receive calls. If I purchase a new SIM card, I would have to cope with two bills. Again, no more advantages.
Breaking news: I just noticed that the Sony Ericsson Walkman phone I am using as a modem only gets 1Mbps download, exactly the speed my provider guarantees. My P920H can get more than 10 Mbps on times, but usually between 3 and 5 Mbps. I believe that V28b stock ICS somehow unlocks some sort of ISP speed limit. Now, more than ever I want to use my phone as a modem on my router.
I’ve received my One on Monday. It’s working very well except it won’t connect to the Wi-Fi network at my work place.
1) The phone connects without problems to my Wi-Fi at home
2) I have the exact same Wi-Fi settings for the work network than the ones on my other android phone which was connecting just fine to this network.
I’ve rooted the phone but otherwise I’ve not changed either the ROM or the kernel.Any idea what might cause this or what I could do to fix it?
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.
Hi,
I have recently (last week) joined the OnePlus party by getting myself the 7 Pro after being with Samsung since the S2 days.
I like the phone but there are a few issues I am having.
The main issue I am having is the Bluetooth Tethering. I need this for when I am in my car (Mercedes use this method for internet connectivity). I switch it on and try to connect but after a while it just tells me that the data connection is temporarily unavailable. My mobile data works fine so I'm assuming that isn't the issue. When I am parked on my drive and in range of my home WiFi and I try and connect the connection is successful. It is as if the phone is blocking the mobile data connection when accessing via bluetooth tethering. This wasn't an issue on my Note 9 using the same SIM.
Does anybody have a fix for this or are having similar issues? If this cannot work then it is a deal breaker for me and I'll be reluctantly returning the phone to Amazon.
On a side note I have even tried changing the dun status via ADB Shell after finding what was supposed fix online but it did not help.
Thanks
I am no Bluetooth expert, and it may not apply here, but there are a number of various Bluetooth settings that can be altered in the Developers setting. Maybe something there can help???
Hi Jaseman,
I shall look into that. Currently doing a full backup of the phone to my PC before doing a downgrade from Android 10 to 9. I'm hearing that 10 is buggy so I'm hoping that is the culprit.
Thank you for your reply.
Hey guys,
So basically I drive a 2016 Volvo V70 (car model not so important tbh) and before I got my Galaxy N20U I used to have an iPhone 8+.
At the time when I connected it to my car's bluetooth system, things used to run quite perfectly when playing music. Using the car's buttons I could rewind and fast-forward songs by pressing and holding in apps like Spotify.
Now with the Galaxy N20U, answering calls works sorta well, and I can skip songs forwards and backwards by short-pressing the car buttons, BUT I can't "slide" or "seek" the tracks, as in fast-forward or backwards, like I used to be able to do with the iPhone. I did all sorts of basic troubleshooting like unpairing and repairing the phone, resetting, trying other music players; but the problem still persists.
I messed around with the bluetooth connection type in Developer Mode settings on the Galaxy, but tbh I don't really understand what the settings mean or which one should be right. I'm not really aware what bluetooth version my car has either, but I think it would be an older version since it's 2014-2016 technology.
How can I fix it or tune the settings of the Galaxy in order to solve this? Or are there any apps I could install which fixes this issue?
Another problem with the Galaxy's BT connection is with my Windows 10 laptop. It's a pretty new laptop (HP Spectre 15 x360 2019) running the latest version of Windows 10.
Basically I did what everyone would do and I linked my Samsung to Windows, so I could have a similar continuity experience like Mac/iPhones have, like having a stable and automatic connection, picking up calls and texts from your laptop, and most importantly that your phone shares hotspot automatically through Bluetooth tethering when you're outside of home.
I tried several things like linking and unlinking through Microsoft's "Link Your Phone", and even tried with Samsung's Dex. I tried with both functions on, or one of them being unlinked.
The problem still persists, that it's not an automated and constant connection between the laptop and the phone, and that especially when it comes to automatic bluetooth tethering; then I always have to do it manually through clicking through several menus on Windows and creating an Access Point connecting to Bluetooth like some sort of a LAN connection. Every single time. And even when this connection is established, I'd see a LAN icon on the status bar (instead of signal bars) and when I expand the menu, it doesn't even list the current connection it is on (like "Samsung bla bla bla: Connected"). Instead I just get nearby WiFi networks and that it's searching. I DO get internet though and it works fine for the most part, but once I leave the room and the phone gets out of the range, or I put the laptop to standby, then I have to repeat the process all over again.
Even when I opt to sharing internet from my phone to the laptop through normal WiFi hotspot, I notice that the connection drops frequently.
To summarize, when it comes to both the car and my laptop, my Galaxy N20U does connect to them and offers the basic functionalities of the BT connection, BUT it misses other basic functionalities and it tends to be a half-baked, unstable connection.
Please help me out with this! Running the latest versions of softwares on all the named devices here.
For now turn off Developer options.
Clear the system cache on the boot menu
Reset network connections.
Pretty harmless and it may fix it...
dont have that problem
