Problem doing VPN - Samsung Galaxy S9+ Questions & Answers

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.

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.

S9+ work with IPSEC!

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.

Hotspot problems - Cannot use hotspot from laptp

I have full 3G signal on my Samsung Galaxy S2, and I can easily use the browser on the phone to browse, as well as I am connected to Skype.
However the hotspot I am creating does not work for my laptop.
- My computer is connecting and gets an ip
- The android phone is still working
- I can create Open network or WPA2 PSK, yet none do any difference
- Even if I receive an ip address on the laptop, it still wont let me browse. It wont even let me browse on ip's, so its not even a DNS error.
I am out of options at the moment and I cant figure out what to do from here. I cant seem to find any solution anywhere, so XDA is my best hope.
And I even tested this from 2 different computers. One running Win XP another Win 7. None of them were able to connect (past) the hotspot.

There's some weird behavior on the native hotspot function. Are you using WPA2 encryption? Does it work with no encryption? (this is typical)
I read somewhere if you are using WPA2 encryption, and use an 8 digit password (must be digits - no letters, and has to be 8 long, exactly), then it will work.
did it ever work before? Is it possible that your carrier blocks tethering? Does usb tethering work?
It did not work with: no encryption either
However I will try now to see if it will work with WPA2 and 8 digits only.
Do you know of any app that allows me to fine tune the hotspot settings on the phone? I want to select more options than the two it gives me at the moment.
EDIT: Haha this is so insanely stupid. I am talking to Orange UK at the moment and apparently they have BLOCKED tethering!!! I am already paying for a 500MB package on my subscription but this does not include tethering. I have to pay another 4£ for 500MB which will be specifically for tethering. WTF! They are selling the same product twice????
EDIT 2: They are telling me that this is an Android block installed by Orange. Question is how I can get around this and use my existing 500MB. Does anyone know how this can be solved?

[Q] PPTP VPN connection failed using the MobileAP from Dell Streak [Official ROM 407]

I have two phones with the same SIM card.
1. Samsung Galaxy S2
After activated MobileAP, my iPad will be able to connect to my PPTP VPN server.
2. Dell Streak 5
However, in my DS5, the connection to my PPTP VPN server seems blocked.
Anyone face similar problem?
Hello CharlesCCO,
After reading the whole question 2 things came to my mind so i though to describe you in detail to pass you some decent knowledge which may be productive for you.
Well, there are two conditions which i think is in your case;
To start with the first, as you have 2 mobile phones and you are willing to connect vpn on both...If you are trying to use vpn on both simultaneously then it is not possible with every provider because not all the providers support simultaneous connectivity. So, i will recommend you to first try to connect vpn on different time interval on you both phone. If that does not work then, ask your vpn provider either they support simultaneous connectivity or not.
The second part is that, it might be possible that there is some problem with the configuration on your phone. So, you can try configuring it once again. It will going to help you indeed!
I have been using vpn on multiple devices and for that currently i am using hidemyass because it allows me to use 2 simultaneous connection. I am using the same on my lenovo notebook and on my iphone vpn . I have tried pptp vpn as well as l2tp vpn and both are good...
Hope this will help you...and if you have further problem with then feel free to ping me on this forum. i will give my best shot to solve your query

Tethering with Galaxy S3

Hello all,
I currently have the iPhone 4 and I hate it. I want to move up to the S3 but the only thing preventing me puling the trigger is tethering.
Currently I have a jail broken iPhone and MyWi installed for free tethering. Is there an alternative to MyWi for the S3? Can a rooted S3 be a WiFi hotspot (Infrastructure not AdHoc)?
Thanks in advance,
-NJDevils28

Rooting an android phone allows you tether without most carriers noticing.
Depends on carrier also

Ok, awesome answer!
Here is another question. Is there a TuT out there to root and tether? Is it AdHoc or Infrastructure? I need infrastructure as my stock Nook can not connect to AdHoc.
Thanks in advance.
Open Garden Tethering is amazing for a rooted phone. Kinda slow (but that's because my LG Ally is slow, and it only has 3G)
My phone has tethering built in as stock and yes it is infrastructure. My phone is from the UK if that affects your question
Some carriers in some countries like to remove or restrict the tethering option. If you're not in such a country then tethering ie. Portable Hotspot is available by default in Android. There is not need to root or install any special app.
When activated your phone will appear as a regular wireless network, ie. infrastructure.
@JSale i am awesome?
in addition we've set up a network on a demonstration with 10 sgs3 on the same tethered connection, so clients number is not limited to 5 like it was on sgs2
sorry, the language is hungarian

I think it may. Knowing the nickle and dime mentality of the US Carriers, I can see them disabling that function in the OS.
If it is built into the OS and then disabled by the carrier could a Rooted Device be re-enabled?

Has anyone had any issues with tethering with the S3? Used to have a GalaxyS on the Three network and it was fine. Got the S3 and it constantly drops net access. Connection between the phone and my laptop is fine, but there are issues with DNS server etc. and on the same network. had a new handset yesterday after advice and help from Three and Samsung and still the exact same issue.
They seem clueless. Does anybody have any idea what the issue could be and has anyone else had the same problem? Tethering via wifi hotspot or usb cable is the same.
Sorry, maybe I should mention that tethering is allowed on my plan.
Does anyone have any idea at all please?
anybody? anyone else had this issue?
i'm having issues with tethering.
If i set security to open it seems to be ok. With any level of security my windows 7 pc cannot connect via wifi.
i've read comments on other forums regarding problems with this.
I've not been able to test out my S3 tethering on 3 yet. Have you had any luck since? I have noticed that the connection while surfing on the phone keeps dropping though.

If you use an International Galaxy S3 (GT-I9300) on AT&T you can tether for free anyway. You can also get away with paying $10 a month for Unlimited Internet.
No need for root. Tethering is already built into the menus.
Had to return the phone and cancel my contract in the end. Three uk say it's a software issue with samsung. I have flagged it with samsung.

Wireless tethering (called portable Wi-Fi hostpost in the settings) worked fine on my international unlocked phone out of the box (no rooting, installing apps, etc.). I'm a bit frustrated I can't connect to AdHoc networks though, but that's an android issue. At least I found a way to use my home computer's internet on the phone via usb with 'reverse tether'.
Tethering the S3
I seem to be having the same problem when tethering using the security option under ONLY ALLOWED DEVICES,
Security is configured under WPA, WPA PSK, and WPA2PSK, i get as far as adding these settings to the ALLOWED ONLY LIST, but when you go to connect on the Wi-Fi screen, and where it says Only Allowed Devices, it says NO DEVICES,
And so the only way to make it works is by using the OPEN option, but be warned this will allow outside users to tap in to your network.
Contacted Samsung on three occasions up to today, all they would confirm was that using the OPEN setting would compromise your security, ive asked them to confirm that the security Only Allowed option does actually work in real time , ive asked them to configure it at their end and tell me the step by step method.
will report back what they say.
I did take the phone back to the shop to get them to configure this secure setting, they failed and said try and cope with the open setting for now.
Reading the above posts that Three have said its a software problem doesnt sound good, sounds like im going to have to return mine as i do internet banking.
any news that you guys have on this aspect would be wellcome.
Cheers,
PS, i should say i am tethering to a Sony Vaio windowes 7

6.0 wifi issue ideas, thoughts and workarounds

Hey everyone, I wanted to put together a thread focusing on wifi issues of different variety and what we can do to potentially fix or workaround the main issues
I personally have been working on a solution for the discrepancy that disallows me to connect to my enterprise wifi at work, lollipop and previous versions connect just fine. So far ive found this issue. May not be easiest nor even possible for some of the issues some of us are having, but i think its worth working towards solutions.

What wifi issues? You might need nrw router.
I was able to connect via guest, then they had lock it due to bandwidth consumption. I have password since im a supervisor and my other phone (5.1.1) connects just fine. The nexus says saved, but when i click connect nothing, doesnt say obtaining ip or authenticating. Credentials are correct and connected before to same network without lock

Does your nexus connect fine to other wireless networks? How can you blame it on the device instead of going and fixing your work network settings instead? There are no wifi issues. Call an IT guy and he will fix your router.

Interesting, I just read through a lot (more than I can believe) of that issue log. It sounds like its technically not a Google/Android 6.0 problem even though the problem arose with the upgrade to 6.0. Have you considered doing what Nick suggested and reaching out to your enterprise IT administrators at work to see if they can or plan to do the necessary updates?

Yeah it connects to others but all devices lollipop and older including iphone and blackberry connect fine. And its known that android m has issues connecting to some wifi that works fine with all other devices. If you do a quick search youll see basically all 6.0 devices (nexus 6, etc) have same issues once updated to 6.0 (hit or miss depends on network they try to connect to, but same story just fine before update). The IT dept are not going to change settings on their network that works fine with 99.9% devices that people have there, since im only one so far with a 6.0 device (IT request MAC address when you get pass) it obviously is some sort of security policy within the os or something of that nature

Yeah, they are hesitant to change what works for almost everyone that connects to it. Also i think itd be a good thing to work on since most IT admin wont change for the very few with newer devices
On a side note i do feel like its more or less a cop out of them to claim its not 6.0 fault because when push comes to shove it works fine but once 6.0 it doesn't and nothing changed on the network
When I had my Nexus 5X, I had issues connecting to WiFi at home until I used the Network Settings Reset option under Settings > Backup and Reset. I think this issue came from the restore of settings during initial setup. Possibly worth a try.
Still, the issue I'm running into now is that my 6P only connects to one of the two routers at home. I have both broadcasting the same SSID though they're different brands and one's an older G router. On my Moto X running 5.1, the phone would connect to the strongest signal. Seems the 6P will only connect to one and never connect to the other. I've had the phone "forget" that one and connected to the other and then it refused to connect to the original. Very odd.
My point in saying this is that I wonder if there's a similar issue occurring in the OP's office. Though the same SSID is being broadcast, its as if the phone remembers the MAC address of the specific router it originally connected to and refuses to connect to any others. Just a thought.

I'm also having WiFi connection issues with eduroam (an often used protocol in UK universities) amongst other including my home dual band ac network. It locks out and can only be resolved by a reboot, which then takes 30-60 seconds to power off. Not normal or 'just an admin' issue. It seems to be software related as it is not constant nor predictable (ie it's not in certain areas and a reboot always reconnects). I'm unconvinced by the 'speak to your network admin' argument as it is neither useful or realistic and incompatible on my current patterns of usage or the issues being reported more widely.
My 6p works fine on my wi-fi router at home, but when I go over to my son's house, I have to go into Advanced Wi-Fi options and change the frequency band from automatic to 2.4 GHz only. Then I have to cycle my wi-fi off and back on. Then it will work on his router. Otherwise, it with keep trying to connect and fail every time.

Yeah, these are the issues (including the issue im having) that im talking about. Theres clearly issues with wifi on 6.0. Its not an issue with the hardware, nor is the solution "buy a new router" or "must be the settings on your companys network" granted most people can connect everywhere they've tried but if they tried where we cant connect or have issues they'd have same problem. Im thinking its a problem due to security policies or something along those lines but we should be able to alter, remove, or opt out of them at our own risk. Just thinking out loud.
Which build are you on? Mine ends in k. See: http://forum.xda-developers.com/showthread.php?t=3248499

Unlimited Tethering: N950U t-mobile Observations/Suggestions?

To the point
I have been working on getting tether working on my phone.
I really want Android Native, or even Linux Native via scripts.
I would also like to better understand why this works as it does (as far as function, not manufacturer/carrier policy)
What Works...
- [VPN servers] and [Proxy Servers] that are hosted on the phone
- DHCP servers (Wifi Tethering Router/etc...) if the network to be accessed is WLAN 192.168.0.x
What doesn't...
- Anything else involving a DHCP server, Wifi(or USB) and through LTE data
# Confirmed something on the ROM due to my having a CM Remix phone that had full ability.
What can i DELETE or ADD to cease this limiter of bandwidth "70KB/s"
EDIT:
- - - Solved tether: Client side ttl set
I haven't found anything on mine. Although Wifi Tether Router by Fabio Grasso I think it is has been the most consistent solution.

Usually I do use his app.
even bought his new one.
However these is something specific thats locking down the bandwidth
I use the T-Mobile One plus international plan and it gives you unlimited high speed LTE hotspot included for $25 a month
