[Q] N9002 built in VPN not working - Galaxy Note 3 Q&A, Help & Troubleshooting

Hi all, I got my N9002 from etotalk rooted and with their ROM (actually I am not sure what the advantages are of this). Anyway, it runs fairly stable with some gapps crashes (?) time to time.
The firmware is N9002ZNUBMI7.
Kies 3 tells me:
Current firmware version : PDA:MI7 / PHONE:MI7 / CSC:MI7 (CHU)
Latest firmware version : PDA:NA1 / PHONE:MJ6 / CSC:NA1 (CHU)
The issue I have is that the build in VPN is not working for me. I am keen to use the always-on VPN feature which third party VPN apps do not offer.
I have checked the router settings (bintec RS232BW) with the manufacturer's service hotline. Everything appears to be ok on the router. The router's log indicated that the tunnel was set up, the phone received an IP from the VPN IP pool but then failed to respond to the router's Dead Peer Detection (DPD) requests. The tunnel was closed then.
The manufacturer's service hotline also confirmed they do can set up VPN with another Android 4.3 phone using the same router settings. I am also able to set up VPN to my router with an Android NCP client on my N9002 - but it doesn't have always-on.
My question now: Do you know this issue? Is VPN working for you with the built in client? Can you recommend a fix for this?
I consider upgrading the firmware. Would this possibly help?
Thank you!

WPA2 Enterprise

Has anyone managed to connect to a WPA2 Enterprise protected network? Using PEAP and MSCHAPV2, I haven't been successful. There seems to a bug in Froyo that was fixed after whatever build the Elocity is using: hxxp://code.google.com/p/android/issues/detail?id=8804 (I'm not yet allowed to post links).
I haven't had a chance to try the latest firmware yet.
Thanks,

Thanks for logging this. I have the same issue. I was beating my brains trying to figure out why my Galaxy S would connect, but my A7 would not with the exact same settings.
Damn it
Noooooooooooo. I am waiting on mine being delivered and the sole purpose was to hook up to my work network which is WPA2 enterprise.
I hope someone out there has a fix for this. Donations a plenty for the person who does I tell ye.
I was able to connect to our network via PEAP just fine however this tablet does not have a proxy setting for wireless (this option is reportedly only available on models with 3g). All of my attempts at 3rd party addons to access the proxy settings screen have been unsuccessful as well.

WiFi connection is stable, but Internet isn't

Somebody please delete my previous thread (wrong forum), thank you: http://forum.xda-developers.com/showthread.php?t=2707468
------------------------------------
WiFi connects to my router and stays connected at excellent signal strength without any trouble. Internet connection however, always disappears after a minute or so. Then my Dolphin Browser either keeps loading a website forever or gives me some error like "Webpage not available". Same story with stock or any other browser. I'm not sure since how long I have had this issue. It surely existed already when my phone came back from warranty service (and I had sent it there because of very short range of WiFi commonly known problem which they fixed by giving the phone new hardware). I think that upgrade to Android 4.2.2 might have caused my problem, but it was such a long time ago that I don't remember now (I don't use/need WiFi that much, mobile data internet is enough for me).
What I've tried so far:
-rebooting phone and router obviously
-factory formatting the phone
-WiFi analyzer app
-changing all the network parameters and re-setting it up
-WPS connecting
-playing with all the WiFi settings on my phone (proxy settings, ip settings, wifi optimization and other)
-finally, today I unlocked bootloader, rooted and installed custom ROM hoping it'd help (but it didn't and now I lost my warranty lol)
What I have:
HTC One X Endeavor
Android 4.2.2 HTC Sense 5.0
Android Revolution HD 33.1
3.1.10-g7f360be Kernel version
TP-LINK
N750 Wireless Dual Band Gigabit Router
Model No. TL-WDR4300
I'm thinking about installing other ROM, some that works on Android 4.0 or KitKat, could it help?
Oh, and I should add that two different notebooks, Galaxy S4, S3 mini, Xperia X10 and a tablet all work fine with this network :>
I can provide any screenshots, photos, names of devices etc., just tell me what is needed.
HELP!
I have a similar problem with my device, but I just reset my router and it's fine. Maybe your problem is that your phone doesn't receive an ip address. You can check out if you have received an address via settings->wi-fi-> advanced, and check the 'ip address'. If it says ' not available, reset your router and your phone's wi-fi until you get one.

Nopes, IP reception is fine. Here are all my settings:
Status: Connected
Signal strength: Excellent
Link speed: 26Mbps
Security: WPA/WPA2 PSK
IP address: 192.168.0.101
Proxy settings: None
IP settings: DHCP
As I said earlier, I have been playing with all the network settings above as well as with the phone WiFi advanced settings and it didn't change anything.
Hm…it may be a hardware problem.

VPN not working in CM11

My VPN is not working in CM11. I have tried all settings and variaties for my VPN provider but none seem to work so I have raised a support ticket with them.
I am seriously hoping this is not a CM11 issue with VPN not working because part of my reason for upgrading was so it would remember my settings and always be on.
VPN on CM11

@sevenrock
Thx, but that seems for openVPN only.
Any idea how to use L2TP/PPTP VPN ?

[Q] Android Lollipop - Wifi Problem

I did a clean flash, but cannot connect internet through wifi. There wasn't such problem before lollipop.
Other devices connect without problem.
Chrome says DNS_PROBE_FINISHED_NO_INTERNET
Mobile network works fine btw.
What might cause that?

Is it happening with all WiFi networks that you are connected to? Because it seems related to the DNS configuration.

No, only University's WiFi
I have the same, really annoying problem.
I use a local DNS to resolve my LAN name server, but the device on Android Lollipop never use the Local DNS and it ends with a 404.
I use "Fing" / "Ping and DNS" to do my network test, it says the hostname can't be resolved... and the DNS used is one on IPV6 (2a01:e00::1)
I have a lot of applications inside my private domain ( *.dk.lan ) managed by a bind9 / dnsmasq (I have tested both) server on Raspbian, and all was pretty good with Kitkat and lower (and on Mac OS / Linux )...
I have 8 devices, 5 on Lollipop with this problem and 3 on kitkat without it.
Some thread seems to appear on Internet about this kind of problem...
And, after investigation, it seems the Android Lollipop device use an Ipv6 DNS name resolver instead those send by the DHCP server...
If you have an idea... I'm listening !
About this problem, I've opened a issue on the Android tracker : https://code.google.com/p/android/issues/detail?id=79504
I've been investigating this issue and it's seems that it's a kind of problem on how the OS stores the DHCP parameters.
If you try to make static the same configuration in my case it takes a /20 (255.255.240.0) network like /29 (255.255.255.248) ..... and this doesn't happen if the network it's the ussual /24 (255.255.255.0)
Not fixed in 5.0.1
Finally fixed in 5.1

Note 4 and issues with some Wifi

Hi, i have my Samsung Note 4 phone and O.S. ver. 5.1.1 stock firmware, no root and build N910FXXU1COH4.
I've noticed problems on Google Search, Facebook and upgrading on Play Store when I'm connected to some wifi network.
Recently I configurated at my friend a station to receive Internet connection (Adsl) from his brother and I installed him a TpLink Cpe and an access point with ddwrt software installed.
Then...my Note 4 has the problems I said and pc, Samsung S3 Neo and another Samsung work regurarly for all apps, upgradings and searchings!
I don't know why I have this issue in my Note 4!
I configurated the Cpe setting as dns (not obbligatory) the ip of his brother's router connected to internet.
I tried to insert 8.8.4.4 with static ip but I don't fix the issue.
P.e.: i noticed that the issue is caused by upload that is about 0 Kb/s and others devices don't have this issue.
Do you know why?
I also upgraded my stock firmware to COJ3 but i haven't solved the issue...[emoji53]

From what I can understand there is an issue with Lollipop where if it sees IPv6 on your network it will always try to do DNS over IPv6, even if its not actually functional. As such, DNS completely breaks when using IPv6 capable routers (guaranteed if you run DD-WRT, OpenWRT, pfSense, etc) if you do not have IPv6 support enabled on your Internet connection.
I ran into this myself recently as I was trying to disable IPv6 on my network as it was not fully functional, but it completely broke connectivity on my Note 4.
The March security update seems to have made this worse, as even after restoring partial IPv6 I can now do DNS but actual connectivity still fails instead of falling back to IPv4 like its supposed to.

Thank you my friend. I read only now your message..
I don't know if we have the same problem.
Now my phone is going with the latest MM stock firmware and I have always the same problem..
Some other phones work good except someone..
I don't know if it's a issue about IPv6 but I can ensure you that I linked all phones in same way to wifi but their behaviour is absolutely different related those apps..
