Hi,
I have changed from my aged Galaxy S9+ to the brandnew S23 Ultra. I am using extensively the S23 Ultra as an AccessPoint. - as I did with the S9+ before - perfectly working - without any troublei n more than 5 years.
Besides that Selinux is taking a lot of (network) functionalities from TERMUX which I was used to before, I am totally disapointed in addition by some S23 Ultra (Android ?) inconveniences:
Supposed the S23 Ultra (shortly S23U) is spanning an AdHoc WiFi for 2 ESP32 MCs and two (old) S9+ Galaxy Smartphones and my Notebook. All nodes are visible with their MACs and IP numbers in the extended S23U Hotspot config menue - so far so good!
Internet Access is given! Of course they are fully accessible by the S23u+.
BUT ...
1. inconvenience: The last two IP network portions of the Hotspot are not static any more. Example - the address is generated exemplarily as 192.168.xxx.yyy, whereas xxx and yyy are given randomly after activating the S23U Hotspot functionality - it is not static defined any more, as it was the behavior before in the Galaxy S9+ world (always 192.168.43.0/24 or 192.168.60.0/24).
2. inconvenience: I am using extensively openSHH. Logging into the S23U from my Notebook via winscp works perfectly. But the two S9+ are not accessible any more via openSSH from my notebook.
Also the nmap view initiated on each S9+ only lists the S23U IP address (and their own adddress), but not the addresses of the other nodes - (although they are fully accessible from the S23U). Internet Access of the 2 S9+ via S23U (as hotSpot) is fine!
And now the most crazy magic:
Sometimes the restrictions of the 2nd inconvenience are totally gone ... all works fine - alle 5 nodes in the network can see and access eachother ... !!!
Then I can login via winscp into each S9+ .... and also do see the IoT devices and my notebook via nmap being processed on the two s9+ ...
For me this seems to be a temporary (random) HotSpot routing problem in the S23U (or in the latest Android version?) ?
Or is this a (known) bug or a "sophisticated" feature of the S23U programmers in order to annoy Android or S23U Users?
And why did this crazy programmers change form the static subnetwork adresses now to random network numbers philosophy ? What shall the benefit be ....?
Or ist the 2. inconvenience a further side effect of the well known Wifi problems of the S23U which pops up everywhere in the Internet criticisms?
What do you think? Have you made similar experiences, please ?
Any hint, any advice, any link, ... is pretty much appreciated!
Thanks very much for reading.

It could be related to android version and Samsung decided to leave as it is. You can report it via Samsung members application with these examples you have provided. I'm pretty sure you will get some kind of response.

Hi,
when my G5 (H850) has booted every thing works as expected for about 1/2 to 1 hour. At first I've noticed that PlayStore did not load some and then no pictures but installing (downloading) apps still worked. All browsers (FF, Chrome, etc.) stop working. No connection. Twitter does not load pictures. After an unspecified time (from about 5 minutes to 1-2 hours up to 12 or more hours) everything works again just to stop working after a while. When I reboot every thing works immediately.
My network is IPv4/IPv6 dual stack. Perhaps this is a side effect of my dual stack set up. Are there any known problems with IPv6 (and/or dual stack, WIFI) on the G5?
As a test I will create a separate VLAN and SSID with IPv4 only just to find out if IPv6 is the problem. If I find IPv6 is the problem the next question is if the G5 has IPv6 issues or my network set up is faulty. The second option seems to be unlikely IMHO as all other devices (computers, Samsung tablets and phones, LG tablets and phones, iPhones) work as expected.
Any hints and suggestions welcome.
TIA
IPv6 causes issues in a LOT of cases in my experience, and not with any specific device. I've given up and just disabled it on my whole home network. It's the networking of the future and the future is not today
Pretty strange statement for 2016 after about 20 years IPv6. IETF stated that when they talk about IP then IPv6 is ment and IPv4 is no longer actively worked on. There is no alternative to IPv6.

Hi,
I am just a Android user, but I believe my observations and questions are interesting and relevant to people in this forum.
I use a Samsung Galaxy A3 (2017) and wanted to use one of the many VLC remote control apps towards my Ubuntu computer that has a Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (Lite-on). Unfortunately none of them worked. All had network issues. I tried different ports and also used several browsers to access the http server of vlc directly, but even the browser had issues: it basically kept synchronised for 4 or 5 seconds, then lost synch and recovered only after roughly 15 seconds just to loose synch again after 4 or 5 seconds.
I checked the TCP connection. It did not break down. However, every 4th or 5th GET request got delayed by around 14 seconds.
I digged into it and found out that the A3 sends a TDLS Setup Request to the QCA9565, gets a TDSL Setup Response and then sends a TDLS Setup Confirm which is replied by the QCA9565 with a TDLS Teardown. After that, the connection between the two hosts is dead for about 14 seconds.
Other hosts in the network did not have such issues, but as far as I can see, they are also not using TDSL. So I suspect that some issues with TDLS between my Samsung A3 and my Ubuntu machine regularly interrupt the local WiFi connection between the two.
So now my question: Is it somehow possible to disable TDLS on my Android phone? Or are there any vlc remote apps around that somehow suppress TDLS for such local WiFi communcation?
Thanks
Michael
Hi all
I've setup VPn tunnels to my office on my S9+. I've setup a PPTP from the built in client and IPsec and SSL from the Fortinet Client and none of them are working.
I'm sure that authentications are correct as I use same settings on my laptop running windows 10 and on a iPhone 7 plus.
Anyone with the same problem?
This might not help you exactly but there seems to be an issue with the stock ROM and VPNs. Adguard, which blocks ads via VPN, was also having the same issue and the devs have reported it to Samsung from what I understand. The fix will probably come during a later update since VPN issues are a bigndeal, especially for people who need to use their devices in a corporate environment.
My VPNs include one PPTP and one IPSec/PSK, and they both connect without issues on four different Verizon S9+ phones.

Hi
same here . It's little different for me
PPTP work with S9 but in hotspot, i can't connect to PPTP VPN on my laptop with wifi of S9 !
There is a really problem with PPTP ...
I opened ticket here : https://forum.xda-developers.com/galaxy-s9/help/hotspot-vpn-pptp-issue-t3765773 !

Hola
I just wanted to give you a heads up that Adguard dev's have figured out a temporary workaround to make the their VPN ad blocking features stick. You'll need to check their forums for the actual setting (or use their nightly release which has the setting enabled by default). I have this setting enabled and now I am able to browse ad free for the most part without issues.
I've just update the phone and it's now working yet. Besides that the problem is even worst because I can't even connect VPNs on my laptop if using the phone as hotspot.
I've reported to Samsung and I'm waiting for a call and a remote assistence but if I can get a fix in a few days the phone will be returned because this is a big issue for my work.

I used this functionality fairly frequently with my (Verizon) S8+.
I've just completed about an hour of testing with my (Verizon) S9+.
I tried the USB tether, the Bluetooth tether, and the Hotspot networking on the phone. In each case I established a network connection to the public Internet without issue.
The VPN connections from my Windows 10 system, however - using that S9+ connection - all fail now with one exception.
The PPTP, L2TP/PSK and IKEv2 connections (that all work[ed] with my S8+) will not connect using my S9+.
The one exception is the Microsoft-specific SSTP variant, which tunnels over port-443. That one will connect with the S9+ in all three networking scenarios - USB, bluetooth and Hotspot WiFi.
This seems to indicate that the new phone does not pass TCP port 1723 and/or GRE 47 (PPTP) and UDP ports 500 and/or 4500 (L2TP and IKEv2) through it's network tethering and the WiFi connections.
Bummer.
At least I can still use SSTP to get to my server resources - which is 90% of my VPN needs anyway - but the other connections are dead now.
Connections FROM the phone, using it's built-in PPTP and L2TP profiles to host networks, continue to work properly on the S9+ -- as they did on the S8+.

That is the Snapdragon version? Does it have a special ROM from Verizon or is the stock Samsung?
Maybe that is the difference

Stock Verizon (SD845 8.0) S9+ compared with a stock Verizon (SD835 7.0) S8+. I suppose the difference might be explained by going from Android 7 to Android 8, but I have no way of testing that hypothesis at this time.
(The last phone I modified was a 2013 Motorola RAZR. I've subsequently switched to using my phones as phones, rather than as a hobby. )
If someone has a different experience with employing a networked platform's VPN while using a similar phone in a tethered or hotspot configuration, it would interesting to know.
My own successes with the phone's built-in VPN (PPTP and L2TP) - as separate from the scenario described above -
apparently differ from those of others in this thread for reasons I cannot explain.
I'm in the same boat - a new S9 and can't connect to my work VPN when using the phone as a hotspot. It works fine on S8 and Iphones. Does anyone know how to fix this? This is a critical issue for me as I work remotely quite a bit.

I think there is no fix yet. I had someone from Samsung support connected to my S9 last Tuesday and they could not find anything so they escalated the problem inside Samsung but until now no further news.

CPU - Exynos 9810 - 2,7 GHz, its on Croatian network - T-Com ( T-mobile ) - locked.
New update in germany : G960FXXS1ARD1
Maybe a good patch ...
My S9 unlocked (SD) can connect to my L2TP/Ipsec VPN but disconnects within a minute or so (even if the connection is under constant use.) I have another Anrdoid 7 device (and a Windows 10 laptop) that has no problem with the same VPN/router/WiFi combination and can stay connected for hours. I don't know how to escalate this with Samsung in a way where they just don't blame my other hardware.

I want the application I am developing to use the Wi-Fi and Mobile Data (cellular) interfaces simultaneously on my Android 11 Galaxy Tab S7 5G device. The setting "Mobile data always active" does indeed allow fast interface-changeover. However, both interfaces are never data-accessible simultaneously. Using a third-party channel-bonding VPN service, called Speedify, this is possible on this Galaxy Tab S7 5G tablet. Speedify uses something mysterious called channel bonding with their VPN service to accomplish this. Also, a Google Pixel running Android 11 is also able to use both interfaces simultaneously, without any third-party utility help. In addition, the Garmin ActiveCaptain App also, somehow, gives this tablet the ability to communicate on both interfaces, simultaneously. How can my application use both interfaces on a Galaxy Tab S7 5G without using the Speedify App (not possible because of security and business reasons)?
Did you get anywhere with this?
How have you verified the Garmin app has this functionality? And when are both interfaces used? I wonder if only one channel has a typical data connection, and the other is for some other purpose (location, or something).
I think Speedify gets around the usual OS limitations by creating a single virtual device that all requests go through, then they decide which network to send packets on. It is neat to hear this can work on a mobile device though! I had assumed their service was for people on more typical PC like hardware.
In a way I'm not surprised Google's own phone has managed some tricks others haven't. Though I'd hope it wasn't an Android 11 only feature (meaning 12+ don't/won't have it).
This assumption of only cell or wifi being active might be baked in at an OS level to force better battery life. Personally I like flexibility and choice, but I can imagine less knowledgeable users getting angry at their terrible battery life (after they enable a feature they don't understand).
Maybe this is worth filing a bug with Android and seeing what they say? Or asking Samsung directly?
I was bummed when I figured out I couldn't just pay two ISP's for internet service and load balance across both easily. That my consumer router's optional 2nd WAN port was only a failover option (use one or the other).
As you alluded, for Samsung phones and tablets running Android 11 or Android 12, the ultimate solution is to route both WiFi and Mobile Data (cellular) data through a virtual interface e.g. tun0, via a VPN tunnel interface. I believe this will "shield" the Samsung one-or-the other route-switching that prevents simultaneous operation over both WiFi and Mobile Data. I am assembling just such a VPN now. I could certainly use any tips or suggestions from others that have already been down this road.
I'll be writing this as an extension of my previous more first impressions review of the phone, beginning with some things that have been fixed since that post.
Some of my biggest complaints were related to gesture control, I'm happy to report that mostly those issues have been resolved. The screen off gestures now work as intended and replacing the stock case with one that goes fully around the edges of the phone has made the smart key usable without worrying about false activations. Palm rejection issues have also been solved by switching to a slightly thicker walled case that goes all the way around the phone edge.
Before I get to some new issues i do want to go with some new positives I've noticed over the last month.
Spent some time in a place with 5G support which was a great experience overall, if only my home Internet were that fast.
AliExpress sellers seem to be giving the phone some decent attention, been easy to get accessories (screen protector, case) even in Canada where the phone isn't released.
Dual band WiFi has been more useful than I anticipated, kills the dead zones in my house, improves local file sharing, and unlike oneplus's solution is seems to work everywhere, not just a handful of apps.
Battery great, takes a little tweaking to turn off features you won't use but once you do you can go all day without charging. I don't even bring a charger with me out anymore. Charging features are also there to help ensure it stays that way long term.
It's not all good news though, I have had some new issues as well.
Had a crash, no idea what caused it and no luck recreating it. Got booted into a corrupted operating system message. A forced reboot seems to have fixed the issue.
There being no way of setting a fallback private DNS server is a puzzling omission, makes using something like nextdns an issue without switching to a vpn based DNS switcher. If your DNS provider is blocked by a network tough luck.
USB keyboard detection is a bit jank, my Keyboardio Atreus can type just fine (using it now on the phone to write this) but it does not get detected as a keyboard in settings so the on screen keyboard is forced on. This is not an issue over Bluetooth, just USB.
The raise to wake option seems to activate in pocket even with pocket mode enabled.
That's all that comes to mind for now. Most of my new complaints are pretty minor, I'd say the DNS issue is the only one that effects me with any regularity. And just like my previous issues none are hardware issues and should be fixable with updates from ASUS. I still am of the opinion that the phone has a good value proposition and don't have any misgivings about the purchase. Most of what I like about the phone is in my previous review and I stand by pretty much all of it.

Is there something that can do this? My S22 Ultra, OnePlus 10 Pro, and iPhone 13 Pro all does not appear to support backup private DNS. When I'm using the S22 or iPhone, on a network that blocks DNS, I have to go manually disable private DNS. On the OnePlus it seems to fallback to basic DNS but I don't see an option to set up a manual backup

DNS 2 is the backup for DNS 1. IOS 16 let's you add multiple DNS servers, i believe with the new OOS you can't do it for every network at once but you can set a different DNS server for a network individually. It's also a standard feature in most custom roms.

Given this response, I suppose you mean to set up a dns server per connection? Private DNS (as in, the DoT option) doesn't have a DNS 1 or 2 slot, and in IOS 16 you still set up DoH via management profile.
I just checked the following devices:
OP8T (on Nameless AOSP) and private DNS only has 1 field (Settings -> Network & Internet -> Private DNS).
OP10P (on OOS), 1 field (Settings -> Connection & Sharing -> Private DNS)
Moto e (on whatever the hell moto uses), 1 field (Settings -> Network & Internet -> Advanced -> Private DNS)
iPhone 13 Pro (Management profile only for DoH)
Apologies if I misunderstood, but I don't see where a DNS2 field would even be while using private DNS

When i say private DNS I'm not talking about DoT (i see why that's confusing), I mean using DNS that's not the one provided by the network, one that you own, be that over TLS or HTTPS.

Thanks for this. I was getting worried, since many have mentioned these two issues. I'm glad you found a workaround.
Would you mind sending a link of the case you wound up using?
