Galaxy S7 disable IPv6 - Networking

Hey guys, trying to VPN into my home network so I can view my home IP cameras. Everything works great with all my family's tablets and phones, except my new Galaxy S7. I am running PFsense at home and when I use the exact same OpenVPN config file that works fine on all our devices, my Galaxy S7 seems to be trying to use IPv6 instead of IPv4. I have IPv6 disabled on my home network so this one device isn't working. Any way to disable the IPv6 on Android/the S7/ or just for the VPN connection? Any help would be much appreciated as I used to use my phone daily to connect to my home network.

Global authenticated http proxy

I'm a University student who would love to use this tablet at uni. Connecting to "eduroam" is not a problem but the proxy support in samsungs rom is. It's easy to put the proxy details in the wireless advanced settings and get the default browser working. But without dropbox and a few other key apps, it's useless.
I previously had an Iconia a500, rooted with various roms over the time I had it. I found an app called proxydroid which worked brilliantly with all of the roms and even started the global proxy specifically when connected to eduroam the uni network. My problem is this app no longer works, i've tried every other proxy app out there and can't seem to get it working. Interestingly enough my original Galaxy S worked fine as well but my new Galaxy Nexus running cm9 has the same problem.
I can't figure out the underlying cause! Any help would be appreciated.
I use proxydroid with no problems at all

VPN works fine in Wi-Fi but not with 3G

I'm hopeless here. I have a paid VPN service, and it works perfectly with my PC, with my mobile on Wi-Fi and with my friend's mobile also on 3G, but not on mine. For sure there's something wrong with my device. I tried hard reset, different ROMS and all different servers and settings.
It does connect to the VPN and it keeps up the connection, but internet just doesn't work. Anyone have any idea why this is happening? I tried to search other threads about this, but no success.
Thanks

Same here ... I search but nothing ... I'm on Ressurection Remix 3.1.3 with Kernel cm 10.1... VPN in 3G don't work
Have you tried the app Go to my p.c. app?

vpn thrue 3g and mobile connection
hi
reason, routing.
1. you have to setup your vpn connection to route any data between your vnp-connection.
or
2. you use another apn who route unsecured and secured data to different routes.
(secured data = VPN, unscured Data => www)
Check the isp apn if it use a stateful paket inspection firewall. this apn can ussually only route secured data (vpn).
Its no bug its a feature to solve some problems like too much connections, timeouts, reduction of hacker attack surface, and more..
you can find this information in the special vpn-whitepaper from your isp.
i hope this helps you.
How does the go to my p.c. app work?Is it pretty good app. Thanks

When you set up the VPN on your phone, make sure you fill out the forwarding fields as 0.0.0.0/0.0.0.0 otherwise no traffic will be forwarded through it. Testing on wifi from the same location as the host is a miserable way to test VPN as it tells you nothing. Turn off the wifi, and always test on your mobile data. There ARE carriers out there that WILL filter out VPN connections for normal user accounts and require you sign up under a business-class account to use such connectivity, this is because they want more money from you, and to not give you an easy way to get around their tethering detection. Plus in some countries, you're not allowed to possess the capability to encrypt and secure your own data/traffic and the means of encryption are banned (and therefore filtered "on-the-wire").
Use VPN Service that has open port. Like http://xtreamvpnworld.blogspot.com ive been using it for more than a year. I got no problem.

That's seems odd. Anyway I haven't tried built in vpn, how about openvpn? Have you tried it? I think built in vpn doesn't support voips like viber etc. Or maybe your vpn provider does not. I really don't know. Because I tried using droid and xtream vpn it works on every chatting platforms.

i dont know what does that mean but my modem model is

Does your WIFI have SSID broadcast enabled? I've run into issues with some devices when I had that disabled. What about connecting to other access points?

My galaxy s2 is working and also samsung notebook.. but there is a problem in s4..... i really dont know .... what does it cause by?
my wi fi modem's model is "inca IM-205NX" can you google it? i cannot enter a website link on forum because of new user
i have some news i guess i will solve the problem
when i enter my modem surface, i see modem passward.. as i write before, my modem is inca, and security type Wpa/wpa2 psk..
when i change security type from Wpa/wpa2 psk..to non-security, i can access my wi fi connection. i mean if there is no password on modem, i can reach but it can be dangerous, hackers can intrude....
i will change my modem settings until solve wi fi problem and i will notify you
okey the problem has been solved guys....
i have entered my modem's surface and changed Security type from WPA*Wpa2 psk to Wep and restart both devices
Web is not so secure rather than WPA*Wpa2 psk but the important point is that s4 is working with wi fi

This is not a solution. Wep can be cracked in 2 minutes and somebody can style your Internet. Change back to wpa2 psk. Changing to wep isn't the smartest selection

Do you have an option to enter the passcode in hex? Seems I ran across an issue some time in the past where I had to do that. Seemed an odd solution but worked for me at the time.

Try with WPA2 TKIP or even WPA, but no WEP. WPA should work. There seems to be something wrong with your modem. Isn't there any firmware update for it ?

So, you could enter the passcode in hex. There's a small chance this could help. You'd have to do the same on the phone obviously as well. Actually, I just realized I don't have that option on my phone (and old Dinc2) so may not even be an option.

Galaxy S4 WiFi problem too
I dont see why this went to a router issue...?? I am having the same problem with the WiFi on my one day old S4. It is almost like the signal freezes because it still shows I am connected with a strong signal but nothing works. I have never encountered a problem before with any other devices(S2, S3 Note2, multple tablets) and saying that it is a router issue and saying that i have to disable security or get a new router is not a solution!
I have seen this same post on multiple forums and yahoo answers but nothing as far as a real answer to the issue or to what is causing the problem. PS...there are two new S4's in the house and both having the same issue....
I'm having the same problem, Brazilian S4, at my girlfriend's house, I could not connect to Wifi, the modem is a Fiberhome HG110-B.
Same issues here unfortunately. I think it's the router. Wifi at work is fine. Wifi at home has issues. That's a bummer because I love my Amped Wireless Router at home.
Same issue
Hi Guys,
So my S4 is also just a day old, and I am having the same issue, tried everything, only connects when I remove my wifi security(obviously not ideal), I am brand new to Android, jumped ship from Apple .
I dont have then exact model number with me now(at work) but my router is a trendNET something something 335.
All my other devices connect to my wireless without issues accept my S4, it is very annoying, we are still being screwed over by our Mobile Operators in South Africa, hence the fact that my wireless is so important to me..
Thanks for the help!
actually we have to wait for new update... hopefully samsung will solve that problem...
i am now using with low securtiy (wep) but i don have any choice now
My fix
My FIX
Hey dudes and chicks,
I used to have this problem too with my s4. Connecting just a minute or two and after it would just lose connection. At first i thought it had to do with something from the hardware, but i figured that was not the problem since it did have a stable wifi connection at my uni.
So the problem for most of the people is within the router. Here's how i solved it for me. (I have a Sitecom Wireless Media Router 300N WL-350 with 2.4 and 5 ghz, so the steps might differ a bit if you have different router)
-------------------------------------
1. Login to your router
2. Go to the setting for wireless 2.4 (probably radio 1) (For Sitecom go to tab Basic> subtab Wireless 2.4 GHz)
So what i changed here is the 802.11 mode. (there are several modes like: just 802.11b, just 802.11g, just 802.11n, mixed 802.11b and 802.11g, mixed 802.11g and 802.11n ........)
>>> I Put It On: "mixed 802.11g and 802.11n"<<< (it used to be on mixed 802.11b, 802.11g and 802.11n)
3. Secondly i disabled Auto Channel Scan. This allowed me to select a Wireless Channel (frequency/channel).
>>>I Chose the highest channel ("2.472 GHz - CH13")<<<
4. I used to have the Transmission Rate at the option "best (automatically)"
>>>I changed this to the option: "54" (Mbit/s)<<<
5. I have channel width at the option: "auto 20/40 MHz" (but it always used to be this one)
Furthermore i have the following settings:
> Security mode: "WPA - Personal"
> WPA Mode: "WPA or WPA2"
> Cipher Type: "TKIP and AES"
------------------------------------
Now running stable for more than 6 hours (incl heavy use like youtube and movie streaming from samba server). I believe that step 2, 3 and 4 are the most important ones. If this does not work immediately, try to play a bit with step 3 and 4
Im not that technical but if you have questions feel free to ask.
Help out your fellow Galaxy mate by letting them know whether this worked or not ;-p
Ill also post my fix at this thread http://forum.xda-developers.com/showthread.php?t=2253471

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..

Note 3 problems with OpenDNS

Can someone help?
I am trying to have my kids Note 3 to go through the OpenDNS service for parental control, specifically, Youtube blocking.
I subscribed to the free OpenDNS service and tested it with WIndows 10 computers, Galaxy S7, Ipnone 4 and Ipod 4 devices. It works great. But my kids have each a Galaxy Note 3 on Android 5 (not rooted) and it doesn't work. Here is what it does:
I put the OpenDNS ip addresses in my DD-WRT router.
I attempt to connect to the WIFI, the connection is established.
A prompt asks me if I want to open the application with Internet or Google Chrome (makes no difference which one i choose)
Once I made a choice, a Google search page opens up, just like a portal page when you connect to a hotel WIFI network.
Leaving the page openbed or closing it won't make a difference, I will loose connectivity to the WIFI within minutes and it will not reconnect automatically.
Putting the DNS addresses on the Device connection or on the router will do the same problem.
I am in Canada and my ISP is Videotron, the Notes 3 are Bell Canada provided but they have no SIM card inside, the kids only use WIFI.
I tried putting the Norton ConnectSafe DNS IPs and it worked fine. The problemis that I want OpenDNS because it's more customizable.
What is it with these Notes 3 that causes a problem with OpenDNS?
Let me know if you need more info.
Thank you.
