VPN direct connection - problem - Android Q&A, Help & Troubleshooting

Hello everyone,
I have problem with VPN software in Android. I wrote "Android" because the same problem appear on every phone with android which I've tried. I have server with which I connect via VPN, server has two internet connections. One is ethernet connection via router (local internet provider), second one is mobile internet. Both solutions use static IP.
Android does not has any problem with connection via router, however in case of mobile internet there is no connection. The program show "Connecting..." and after few seconds there is information "failure".
Settings of those connection are very similar. Anyone know how to solve it ? I know that my description is probably a little bit chaotic but I'm willing to explain everything because it is quite important.

[Q] Wifi connected, can't browse, download internet

Hi everybody, i have the next issue:
I can connect HTC HD2 to wireless network with wpa tkip encryption , but i cannot browse internet, download, and the youtube player shows the videos list but doesnt play them. It is very frustrating... i tried to find a solution but didnt find find anything.
Tried the things with Network connects Work/Internet and other ones but did not work.
Does anyone knows how to solve it, or what settings should i use?
thanks
Uhm the problem you experiencing is not related to the HD2
You need to edit you internet router configuration of your internet connection (at home).
Some were there is a setting called Mac Client filtering. If your Mac adres of the wifi adapter of your HD2 isnt showing in the list and having the status "accepted" you can make netwerk connection but the router is blocking your internet connection.
Adjusting the Mac list of your internet router will fix this.

Galaxy S2 is able to connect to wi-fi router but can't access Internet ??

hi,
I've linksys wi-fi router model WRT54GH in my home & it has a good amount of signal strength to cover entire area.
My recently bought galaxy S2 is able to identify linksys wi-fi access point & connects too with the IP assigned to it, also at wi-fi settings connected being displayed.
Now when I try to access Internet (any url google/FB), it doesn't connect at all.
I tried almost everything about router configuration, restart etc. but with no success
can someone plz help on this ?

In my case the problem was with frozen "WiFi sharing" in combination with juicy defenders "Location" fearure. It seems such combination is dangerous. Solutin (in my case):
1. defroze
2. remove all wifi networks
3. reboot (for "clean" frozing)
4. make WiFi sharing frozen
5. reboot again just for fun
Try to check your router's MAC address restrictions. In my router, as security, I have to add MAC addresses of each device to share internet. They take IP's, connects etc. but does not have accesses to internet
as above, check that there is no MAC filtering set up.
one other thing it may be is the security settings, if you have a WEP Key to access the router it may need the Hex conversion of your key depending on what level of security you have (64bit or 128bit for example)

Try setting up a static IP address for your phone, I presume your network is a 192.168.1.0, go into router settings and LAN setup, give your phone the address in a static DHCP assignment of 192.168.1.5, or any other address in the same subnet your in. Some SGSII's have problems with dynamic DHCP for some reason, some NS had the same problem too,

I have a similar problem and I fix mine temporarily by turning my wifi off, then in wifi settings > advanced, I change wifi sleep policy from 'never' to 'only when the screen is off'. However I have to do this every time I want to use wifi so it can become quite annoying sometimes.
So I can get through however only for a short period of time as it seems as long my Galaxy S2 keeps turning off my wifi even though it's on :/
I had exactly the same issue on Linksys E4200 with my laptop, could connect to network, even to router's attached storage, but not to internet. Restart helped
On SGS2, I couldn't connect to the router at all at first, but fixed this by switching from WPA2/WPA mixed mode access protocol to WPA2 private. But I guess this is not exactly your issue.

Yes, you are right this is not an issue for me.
In fact my SG2 being assigned with an IP address from 192.168.1.xx subnet.
Also at a same time my laptop connected with an IP from same subnet able to ping SG2.

My SG2 being assigned with an IP address from 192.168.1.xx subnet.
So I think IP addressing may not be an issue.
Also another thing I tried was, at a same time my laptop connected with an IP from same subnet able to ping SG2.
So wi-fi router may not be an issue here, whats say ???
Even I am facing the same issue at my office network. I am able to connect to the wireless network but if I try to access any app I cannot browse. This is really frustrating looks like some issue with the modem drivers.
I was able to browse on another wifi created virtually by mobile tethering. This looks like a major bug with the current firmware. Another interesting thing to note is that the Wifi network has a hidden SSID and uses WPA2 auth scheme.
I have seen a Galaxy S able to connect to the same n/w without any issues.
Has anyone figured out a solution to this one ?
Hi, thanks for your reply.
I am yet to figure out a solution for this
Even I am also agree on the probable issue with modem driver.
I've D-link modem.
Are you aware of anything about this modem that can be reconfigured to get this worked ... ?? pl let me know
The wifi router at my office is Cisco Aironet 1200 Series, anyone else facing this issue ?
I'm having the same problem at work connecting my SGS2 with v2.3.3 Official Firmware (customized for Orange service provider) to a Cisco Aironet 1130 AP. I can see that the Galaxy authenticates with the AP correctly and gets IP from the DHCP server, but it cannot send or receive any traffic, although the phone stays connected and authenticated. At home, I use an Atheros based Fonera with DD-WRT without any problem.
As I'm the company's network administrator, I will try to further investigate this problem, but it seems like some kind of incompatibility between the devices or misconfiguration ....

try turn off the wifi, turn off the mobile data and turn on the wifi again
It seems the SGS2 sometimes has problems with DNS.
Try a static IP and use 8.8.8.8 as second DNS server, which is a free Google DNS server.
This fixed MY problems
I rooted my SGS2 and voila wifi worked at my office finally I have been able to find a solution.. love my SGS2 the Beast...
I'm having this same problem..
I think I've tried all the solutions above, but one (Sorry - noob question):
Rooted?
is there a firmware patch or something that I should know about?
Anyone got any other ideas?
ETA:
I can connect to hotspots (DHCP) and at home (Have to set it to static tho)
No internet
AP works - Laptop and i8910 (had to set static and advanced settigs etc). I've rebooted it a few times, set DHCP on and off. DHCP seems to be running on the router

This is an issue with SGS2 with wifi server using authentication protocol TPIK, if you use AES as encryption then it will work without any issues.
That should be a setting in my AP? I can't see it...
If I get a new non-crappy AP is that likely to solve my problem?
ETA:
Ah - that's a WPA thing? Mine only seems to do WEP - is that right?

[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

S3 can connect to WIFI but no Internet

Hello everybody.
Since last saturday i'm testing a Galaxy S3.
I want to test if everything works properly before buying it.
I have some problems deling with the WIFI stuff.
I gave him a static IP (192.168.1.15), configured the gateway as the ip of my router (192.168.1.1),
the network class is 255.255.255.0 (network prefix = 24), the DNS points to the IP of the Router (192.168.1.1)
It connects without problems. form the S3 i can ping any device in my network and from other devices i can ping the S3.
I can connect to the configuration site of the router and from the page of connected devices i can see that the S3 is connected
with the correct ip and also the MAC adress is correct.
And for now everything is fine.
Problems raise up when i try to surf internet. The answer is always "Page not found"
If i open the browser and try to navigate to google] the answer is "Page not found". Same for any other site i try to connect with.
I cannot ping external adresses from the S3. Only the ones inside my LAN.
On the same LAN there are 3 laptops, 1 IPhone, 1 TV, NAS NETGEAR , home automation screen, all connected in WIFI.
All of them configured in the same way. (static ip, gateway=ip router, dns = ip router, network class 255.255.255.0),
And they all access internet without any problem.
The network is protected with WPA2/PSKey, encryption AES.
I tried to configure channel with WPA, WEP, without protection, but no changes.
The S3 connects to router but does not connect to internet,
I also tried to make it point to a public DNS 8.8.8.8. No WAY!
Works for other devices.
I tried to reset S3 to factory parameters, same thing i did for the router.
I reconfigured everything from scratch but no result.
I do not have any filtering based on IP or MAC adress on my Router.
I tried with DHCP, with reservation of IP adresses or without reservation. No change.
Other devices can access internet. S3 does not.
I have to say i'm quite desperate.
If you guys have some good ideas to solve or diagnostic the problem i would be grateful.
Cheers,
Fabio
I get that around my office as I walk around, I find that when I change AP in range my internet connection drops. I have to constantly disable/re-enable WiFi.
Even around my house, I have the handset to WiFi always on, yet when I wake up in the morning the internet connection is not working yet there is an IP. I couldn't be bothered to telnet to port 80 etc., but I hear that the Jellybean update will resolve this issue.
Same problem

Me too... Is anybody has solution for this issue?
Oh poor fellows ....try to add DNS manually according to your ISP...not add public DNS
Try forgetting the network and connecting again and make sure all the other devices are using different ip address
