[Q] Auto connect to VPN - Android Q&A, Help & Troubleshooting

Heya,
is it possible to establish a pre-defined VPN connection every time my phone connects to an (unencrypted) WiFi before any other data gets transmitted?
I'm using: Samsung Galaxy S I9000 2.2.1 DocRom XWSJ8 9.9.5
Thanks,
bootsy

There are things like killswitches that presumably do what need.

[Q] Samsung Galaxy S2 allocate the device as multiple addresses on wifi

Hi all
I have had this samsung galaxy for about 3 month the fault I am having is that when I am at home my wifi on my samsung galaxy s2 works fine soon as I go to work and connect via wifi it finds an ip address on the network connects via dhcp but randomly it takes other ip on the network like eg. 192.168.1.104 which is a static ip on the network as well as this it takes the static server ip as well could this be a application issue or is this a fault with the phone.
I have got gingerbread 2.3.5 install custom rooted chainfire basic rooted device.

[SOLVED] Galaxy Ace connected to Wi-Fi but no internet.

Well, the title says pretty much all .. I earlier didn't have this problem.. Then since last night, I came back home and connected my Galaxy Ace to my home wifi, but this time, it wasn't transferring any data.. It would be connected, full signal, but no internet connection.. My browser, gmail, YouTube, PlayStore, nothing would load.. It'd keep saying Connection Error. Retry.
My wifi works properly on the computer and other devices, and my phone used to work perfectly too! Why's it suddenly giving this problem?!
Any solutions!?
SOLVED!
Okay so I figured it out on my own!!
I went to Wifi Settings>> Advanced>> and "Use Static IP"
I then provided my phone with an IP address, gave the DNS servers as mentioned by my Router, and gateway, is ofcourse, the IP adress of the router. NETMASK is Subnet mask ..
Once I filled in them correctly, and as per my router settings, my mobile is now transferring data and I can now access the internet!
Just thought I'd post a reply incase anyone else was facing this problem
No data through laptop hotspot.
I have a similar problem, but with using my laptop as an access point. My Samsung Galaxy Ace had no problem connecting to either my or my wife's laptop access points initially till about a week ago. I use an HP while my wife uses a DELL. We both run Windows 7. But, here's when things started to get strange.
1. The Ace even though connected through my laptop's AP Wi-fi cannot send or receive data after the first few seconds.
2. My wife's Dell XCD35 (ZTE Blade) has no problems.
3. The Ace has no problem connecting to an Android AP or my wife's laptop AP.
I reflash and unrooted my phone and basically brought it back to factory settings but no luck.
Tried using other services for using my laptop as an accesspoint - mhotspot, virtual router and connectify - still no luck.
tried static ip - no luck.
reinstalled the MS Virtual Wi-fi Miniport Adaptop driver - no luck.
Somehow, there is a security setting on the laptop that's preventing my phone from connecting to the internet. I think I maybe connected to the network, but access to the internet is restricted.
There are no other features like MAC address binding or anything like for laptop APs.
It's getting really frustrating now.
Any help would be appreciated.

Set your Internet to "Allow other computers to share this Internet connection". Other ideas would be to check/disable your firewall
Wifi connected but not working
My Galaxy ace plus connects fine to wifi network but cannot browse internet or play store. I am using a free public wifi so i dont know about the static ip address. And this problem was from the starting whn i just bought it. So is there any other solution for this problem or not?
I tried everything... I restarted the modem- no luck. I filled in the blank from the advance wifi setting- no luck

Unable to connect to VPN on 3G

Hi all,
Im having a problem connecting to a VPN on my Galaxy S3 (stock ROM, not rooted, running Android 4.0.4). I can connect to the VPN fine when Im on a wifi network, but when I try to connect while on 3G network it just says connecting for about ten seconds then comes up Unsuccessful.
Initially I thought it might have been something to do with the network blocking VPN connections, but it worked fine on my old phone (Desire Z running stock 2.3.3) and still runs fine if I try it on the old phone with a different sim from the same network.
The VPN in question is connecting using PPTP.
Is there some setting on the S3 that determines whether or not a VPN can connect over 3G? Or is there something else that I might be missing?
Cheers.
Are you sure you're using PPTP and not L2TP or OpenVPN on the old phone?
The network _could_ filter VPN based on the SIM-card but it's somewhat unlikely.
Try comparing the Network APN settings of both devices, especially whether one of both has a Proxy configured.
Now that you mention it I think the old phone might be set to use L2TP, but they changed that setting in ICS and I was unable to use L2TP (neither the PSK or RSA options would allow me to connect) so I had to use PPTP. The fact that it is connecting on the S3 when Im connected to wifi I didnt think it would make a difference; do you reckon that could be the cause of the problem?

VPN wifi tether problem on ALL ANDROID DEVICES

Has anyone been able to connect to a vpn, start wifi tethering, then access the internet with other connected devices?
I connect to a vpn fine on my galaxy s3 mini, start a wifi tether, connect my laptop to the wifi network, but the laptop never connects to the Internet.
A whole lot of people have this problem, and have not been able to find a work around.
I've tried the terminal thingy where you do iptables rputing and stuff, doesn't work, or maybe it was too complicated for me to carry out properly.
Anyone with a solution?
I have a perfectly rooted galaxy s3 mini amd im sure many other devices have this vpn wifi problem.

Wifi tethering connected devices limit

Hi,
Two months ago I installed Cyanogen ROM (Kitkat 4.4.4) on my Samsung Galaxy Ace mobile. Now I am trying to enable wifi tethering for my 3G sim using my mobile.
When I enable wifi tethering I can't get internet on more than one connected device (if there is only one device connected it can access the internet, but when another device connects to the tethering wifi network only the lastest one can access the internet while the first one can't even ping the mobile ip !!)
I tried "Foxfi" and "wifi tether for root users" application, with no hope.
Can I connect more than one device to my Samsung Galaxy Ace wifi tethering network using my current Kitkat ROM? if I reinstall the original stock ROM can that fix the problem? is this a hardware limit or a software limit?
As far as Im aware only one phone can connect to wifi hotspot on ace (cm 10.2,cm11).If second connects first one drops (in my case).For stock I honestly do not know as I've never used it while I was on it.
If you have time and are willing to flash stock,please report result as Im also very curious whether its a hardware of software limitation!
CM ROMs have wifi issues.
