General :: Hosting WiFi Connection With UDP Server?
Oct 14, 2012
I have to create an app that allows other devices to connect to my android terminal via wifi, without access point, so my device should become an access point to host their connections. i don't have to share the internet connection with them, just have to make them connect directly to me, then they send a UDP packet, and I have to read it, so on my device will have to be an UDP server after the connection creation. how to manage wifi? any step to follow? my android version is 4.0.3

I am looking for a way to automate my Android phone connecting to an SSH server when the phone connects to an unsecured wifi network. My understanding is that this is adequate to keep my traffic from being sniffed by DroidSheep (Android), FireSheep (Windows), or other packet sniffers.
I'm using this guide to connect my Android phone to the SSH server: link HERE
Is the Tasker app the best way to do this?
- if yes: how do I trigger the launch of the SSHTunnel when the trigger event (connection to unsecured wifi network) occurs?
- if no: what is a better way?
Note: I did a search for SSH (link HERE) and did not see anything covering this.

Does Android keep the connection between the server/socket when it moves from EDGE to WIFI and vice versa?

I have set up a VPN server on OSX Lion Server edition.It is using l2tp with preshared key and username/password for login. i(beep) works fine and connects. Laptop works fine and can connect.But...
1. When Iam on local network (same IP segment) I can connect using Android native l2tp VPN connection setup with PSK and user/pass.
2. When I try to connect from external (3G or other WiFi net) I am unable to connect.
3. When I enabe native tether on Android device, and connect i(beep) to the Android AP, I still am able to connect from i(beep).
These three steps tells me it is not a carrier issue, and possibly an Android issue.Kinda like the l2tp connection for security, and also Lion natively does not supply pptp connection.

I have a Motorola Atrix2, running Android 2.3.6 on AT&T. I have used Google Talk since getting the phone last December, but for the past week have had trouble.
When I wake the phone I find that I am no longer signed into Talk. My contact list is subdued in grey, a notice appears at the bottom of my chat window saying that the connection with the server has been lost, and my 4G icon has gone from blue to white indicating that I no longer am connected to Google.
I haven't done anything to the phone / settings to cause this. I've tried many things to fix this including: rebooting, hard booting, force stop the application and clearing it's data (cache is always empty), and replacing the SIM. Needless to say none of these steps have worked. I have not tried a factory reset as I have read elsewhere of people trying this with no luck.
As far as I have been able to tell, this problem only happens when connected to my service plan, I have never noticed this happening when hooked onto WI-FI
Having searched online all I can find that might be at fault is the version of Android (the phone originally had 2.3.4 but was upgraded several months ago), and the fact that AT&T has recently upgraded to "true 4G LTE" in my area. I have no idea if either of these are actually the cause of my problem.
Google Talk is one of my two main means of communication and I really need this resolved.

I use an LG Optimus L4 II (e445). I rooted it but then decided I had too much on it and decided to restore to factory settings. It all worked fine. However, when I got to the Google Account sign in page, it gave me the "couldn't establish a reliable connection to the server" error message. I followed every single tutorial I could find online as to how to solve this. None of them worked. Eventually, I re-rooted it (using VRoot) and managed to download an apk of ES file explorer and locate the hosts file. This had one line that shouldn't have been there:
[URL]
From what I can make out, this is the address of google's sign in servers. So somehow (I suspect malware/dodgy rooting program?) my hosts file has been edited to stop me logging into google. Restoring the device does nothing, neither does unrooting/rerooting. When I open up the file in ES (when rooted) and edit out the bad lines, I can't save for some reason- I think the /system folder is write protected.
So I tried to make the /system folder writeable. I used the android sdk to do this (mount -o command) but this did not do anything. I downloaded the mount /system apk and installed that, it did not work either. I tried /pull and /push on the hosts file to edit it and send it back using the apk. I could successfully pull and edit it, but it would not let me push it back. I can effectively not use my phone- I can't use most apps and can't download any.

I'm trying to set up a VPN connection between a Linux Mint 10 PC (server) and a Nexus 7 (client).
All I'm getting so far is a "Connecting" status from the Nexus 7, followed after a few seconds by a "Disconnected" one.
As it is my first attempt at setting up a VPN (both on the server and client sides) I was wondering if there was a log file generated by Android on the Nexus that would give me a clue as to where I'm going wrong.
A similar file on the server side

If my screen locks while I have a wifi connection, then the connection is lost when I unlock the phone.First, is this perhaps deliberate, to save power? Also, either way, when I unlock the screen and go into wifi settings, I see that the phone is trying to make a wifi connection, but it never succeeds, even though it's my home network and I'm in the same room as the router. It just states 'Obtaining address.

Long time reader, first time poster here. How does one know if the Epic is using the wifi connection as opposed to using the 3G connection? When wifi is connected both that and the 3G connection shows at the top. So which one is in control per se? And how can it be verified?

Is there an app or a script I could run to tell my phone not to connect to wifi when 4G is available..? I run with wifi on all the time and have a handful of networks I connect to but would like the phone to automatically disconnect from wifi when 4G is available then reconnect if it is lost. This is useful for me at work because depending on where I am in the building I may have 4G/3G/no data but the wifi is everywhere but it is unsecured so I'd rather not use it if I don't have to.

I'm new here and I'm using a doixanh ROM, GingerDX (but I already used Froyobread). So, some time ago I had a problem...I couldn't connect my device (Sony Ericsson Xperia X8) to wifi.
What I did? I full wiped the phone...and that fixed the wifi issue. But now I have the same problem...I can't connect my phone to wifi anymore!
I could do another full wipe, but this problem would just appear again and again...I googled for some fixes and I found some answers...one of the solutions would be deleting one file (dhct or something) from the phone...the problem is: I don't have that file...
Another (on a youtube video) to download an "hot fix" package with 3 files and place them on the phone...but the link that he gave is broken and I couldn't find those files on the internet.
Like wifi, my phone's GPS doesn't work too.

I would like to be able to share my ethernet internet connection on my android 2.2 tablet via wifi.
I know there are various app's on phones that allow you to share your 3g connection but I have not found anything that I can actually install that will create the same sort of functionality on my tablet, most of the ones I've seen on the play store are simple short cuts giving control over the pre-existing wifi hotspot app.
What I need is the wifi hotspot itself, ie the ability to use my tablet as a router/bridge.

Google Playstore can't connect to the internet (it says no connection). Wifi connection is OK. I can browse the web and the apps (that needs internet connection) works fine. The wifi notification icon is color gray (I know that it must be blue if there is internet connection). I've tried cleaning Playstore's cache, re-install the PlayStore, checked the system date &a time, and reseting the tablet, still the problem exist.
I don't think that the PlayStore caused the problem. Is there any other solutions other than the ones mentioned above. Do I need to re-install a driver or something? Can re-installing/installing a firmware fix this?
My tablet: SoftwinerEvb; Android 4.0.4. (a not so well known firmware)

So recently I have started to have a problem with my Wi-Fi Connection on my Samsung Galaxy Blaze 4G , So I would be on the Wi-Fi fine then each time i click on a video it asks for "Complete action using" then my Wi-Fi instantly stops and the Wi-Fi icon isn't there anymore . After i clicked one of the option on complete action using, couple seconds later my internet comes back.
So problem is that each time i try to watch a video my Wi-Fi Stops when on Web. But then I can watch videos through the Youtube application.
Also Another weird thing is that after the Wi-Fi reconnects My "Use packet data" setting is auto enabled again.

I have a PC running Windows XP, which is connected to the internet using a wired cable modem. I then have a laptop, which I want to use to access the internet, but no wireless router.
Then I realized that my G1 (running Froyo) has WiFi, and I have the USB cable for it. So, is there any way of setting up my G1 to use the connection from the desktop PC via USB, and then broadcast it as a WiFi network? This is only intended to be a temporary solution (a few days) so I'm not going to go out and buy a wireless router or anything.

I do know that downloading on Wi-Fi is faster than using data (or so I've read). My question is if I start a download using data connection then turn Wi-Fi on will the download see the Wi-Fi and jump on that to speed up our do I have to start on Wi-Fi for it to use Wi-Fi?

I am using ICS Evervolv a5 on my N1. The mobile data connection works only if I don't connect to a WiFi network. If I do, the only way I have found to make it work again is to reboot the phone.
This means that while I am at home, everything works through WiFi, however, if I leave home, I have to reboot my phone once I am sure the phone is far enough from my WiFi access point to be able to connect. Then, it starts working with the cellular data plan
The only thing I can relate to this is that I have the "application protection" app installed, protecting the settings menu do with a code so my kids don't mess up with that. However, is still hard to believe that's the culprit.

I have a problem with downloading files from hosting sites such as rapidgator, hellshare etc. On default browser and on Google Chrome files aren't downloading at all or there is downloaded a file which has for example 26kb or so, while I am trying to download files about 400-700mb. On Opera Mobile the files are downloading, but if I will minimize the browser and start any other app, the downloading process is stopped. I am really surprised with that because a few months ago I also had HTC Desire Z and I could've download any file with the stock browser and. while downloading, check any app I wanted.
I have Asus Transformer Pad 300 with Android ICS (newest update). When I download files about 10mb everything is ok, so I assume it's the size problem or maybe file extension, but I tried the app called All files download (or something like that) which has been recommended in a similar post (but that user had SGS3) and it didn't worked either.

Often times "like aboard an airplane" there's someone you want to talk with, but can't, because they're in a different seat. Is there any app that would allow people to:
a) send messages to other Android phones via bluetooth
b) sent messages by connecting to a common wifi network (yet not connected to the internet)
c) create an ad-hoc network and send messages that way.
Would any of those be feasible at all?
