Data communication in wifi network

Hi,
Could you let me know if it is possible to communicate [peer to peer communication] between two wi-fi devices in j2me as similar to client-sever communication in bluetooth? Please let me know if I m missing anything here.
Thanks!

I have used SVN (Subversion) when there was a need for multiple users of the same design. Each can check out the model to their workstation and save changes to SVN. When one user saves a change, those changes are then visible to the other users as inbound changes. If one user makes changes to something another user also changed, they will get a conflict resolution dialog to resolve the issue. This seems a better solution than trying to share a single model folder via Citrix.
Files such as defaultdomains.xml and dr_custom_scripts.xml can also be saved and shared via SVN. I think there may be another discussion on how to do this on the forum already (I think I asked about it a year or so ago).

IPhone 4S uses 3G data even with WiFi network available

I've been trying to figure out why the iPhone still uses 3G data even when it has a WiFi network available. It's usually just a few MBs per day, and as such - I attributed to niotifications, location services, etc.
But today, I got a really nasty surprise...
As I woke up, my iPhone showed the WiFi indicator as usual, but internet was slow... as if it was using cellular data. Something i quickly confirmed by trying to access stuff on my internal LAN and not being able to.
Worst of all, my iPhone went through over 600MB of cellular data overnight - that's my entire data limit for a month! - meaning I'll have to pay for neary 400MB of excess data usage paid at overly inflated prices (I'll be paying nearly 3x my monthly bill just for the excess data!!!)
As if all the bugs I've been facing weren't enough: Invalid SIM, showing full strength 3G signal when it's actually "offline"... Now I have to face stupidly wasted mobile data when I'm at home within WiFi range?
I've been an iPhone use for years, and have upgraded every year to the new models... but this iPhone 4S has been my worst experience ever with a mobile device, and ruined all the trust I had in Apple devices...
I sincerely don't know what to do next... if I'll still wait for a 5.1 update that may/may not fix all the issues I (and thousands others, as seen by the discussions here) have been having... or if I cut my losses and try my luck elsewhere...
Tired of serving as a guinea pig and doing all this debug work for Apple...

The WiFi data is recorded separately - and the mobile data use was verified using the operator "reporting" service (and later sending me the warning SMS of the data use).
The iPhone was in the home screen, locked, and "sleeping" when the data was used, so the only option would be the iCloud backup - which, in any case, should never ever use the 3G data (and never has until today).
If the WiFi was not working, then it should either: not have internet access; not show the WiFi connected signal in the status bar. As it was, it was showing WiFi access, but using the mobile data just the same.
Which, from what I understand, could have "tricked" iCloud into doing its regular backup thinking it was over WiFi... but in reality doing it over cellular data.

Large data usage transfer every 6 hours while on a WiFi network, who is doing this transfer? Is Verizon polling my phone causing this usage?

I have three iPhone 5s. All are using my WiFi while at home. One iPhone is sending data over Verizon's network, not WiFi, every 6 hours or so. The time of this data transfer changes every few days. I see data usage number on my Verizon account ranging from a few kilobytes to almost a gigabyte. Is this due to Verizon polling the iPhone for data usage and billing purposes on a regular basis? And what do these billing numbers mean? Where does Verizon get these numbers? Any running apps while on my WiFi should use the WiFi, not Verizon, correct?

I'm having the same issue and this month these data pulls equated to 1891.51 MB!!!
Model: iPhone 5S 64GB. Today I received a notification from Verizon that I had exceeded my data plan. I just went through my entire usage detail report on my phone and separated-out everything that appears to be part of a 6-hour pattern. When I'm at home and most of the time while I'm at work, I am connected to wifi. These data pulls often happen in the middle of the night, when I know for a fact that my phone is charging and connected to wifi at home. Below are the results of the pattern analysis. Keep in mind that I removed all lines that, as far as I could tell, were not part of a 6-hour pattern.
THE PROOF: You sent me three alerts immediately after pulling data from my phone.
The first alert said that I had used 75% of my data plan on 8/11/2014 at 9:45pm while I was at home on wifi. There was a data pull logged at 9:45pm which was part of the 6-hour pattern above.
The second alert stated that I had used 90% of my data at 10:46pm on 8/14/2014; the data log shows a pull just before the alert at 10:45pm.
The third alert telling me I had used all of my data came today while my phone was sitting next to me, connected to wifi at the office. The alert arrived at 12:48pm, the log shows a data pull at 12:48pm.

How about an explanation Verizon?

HT3819 Hi there. If I use "home sharing" on the same wifi network, does it use internet data, or only sharing over a home network?

Hi there. If I use itunes over home sharing in my house on 2 pc's, does it use data from my internet, or does it work over local home network?

You'd need both computers to be connecting to the same wifi network in order to Home Share.

Use an external HD with Airport Extreme to access it for data storage from computers connected to the WiFi network?

Can I connect My Passport HD into my Airport Extreme's USB port to access it from my computers (27" iMac 2012 now using Yosemite) on that Wifi network for data storage and retrieval purposes?

Yes, if the AirPort base station's hardware supports 802.11n. The drive needs to be formatted as Mac OS Extended (Journaled), FAT16, or FAT32, and may need to be connected through an USB hub with its own power supply.

Does siri use data if on a wifi network

does siri use data package if I'm on a wifi network?

I just was looking for this answer and found your question. I then found the answer... Apple made a BIG mistake and made it so shared photostreams are on cellular! See the quote from Apple below. It makes me think that using something like Everpix may be a better idea as you can control it to NOT use cellular, it is free to use for recent pics (like photostream), and I think it does have the same web and in app share features. My pics aren't up on it fully yet so I can't play with the share feature yet.
"Note: Shared photo streams work over Wi-Fi, Ethernet, and cellular networks. Cellular data charges may apply.
For more information about using Shared Photo Streams, click a help topic on the left."

I'm trying to transfer data (docs, emails) from G4 iMac running os 10.3.9 to brand new iMac on 10.8.1 I'm stuck, any help greatly appreciated. (Ethernet or wifi networking are both options if I can figure out how to get the machines to communicate.)

I have the old machine backed up onto an external firewire disk but can't hook that up to the new imac as I'm waiting for delivery of a firewire 400/800 adaptor - therefore starting the old machine up as a slave is also subject to the same delay.
I was hoping there might be some way to create a network between the 2 machines (and 2 different versions of the OS) to be able to transfer data across immediately but perhaps I'll just have to wait for my firewire adaptor to arrive.
I don't understand why you're buying a Firewire adaptor, since AFAIK both of your computers have Firewire already built in.
All you need is a firewire cable. Connect the Firewire socket on the old machine to the Firewire socket on your new iMac.
Then start the old machine in Target Mode (i.e. by holding down the T key on its keyboard, while it's starting up, until you see the three-legged T icon hopping around the screen of the old machine.)
At that point you will also see a new icon on the screen of your new iMac. This is the hard drive of your old machine. By clicking on it you can navigate through it any way you like, just as you would normally.
Just drag across whatever you want from the old computer to the new one. This will leave everything on the old computer untouched.
- or use Migration Assistant but in my experience, Migration Assistant isn't very reliable and fails to migrate large amounts of stuff.

WIFI and mobile data connections not connecting with any other outside WIFI networks. Bluetooth not working in car. Any solution?

After installed iOS7 I am facing the following two problems:
1. WIFI as well as mobile data connection are working fine at my home. But, not connecting with any other outside WIFI networks. Error message is 'unable to join network'. Mobile data also not connected outside my home. Sometimes wifi and mobile data connect outside my home when I turn off and on the phone.
2. Bluetooth, in my car, paires well and incoming and out going calls can be received and made. The problem is no sound out put from speakers.
Apple please make note of the above problems (of million people) and give solution before giving any other updations for painting and tinkering the screens.

Check this thread, the same solution might work for you:

My IPad is not showing in wifi networks. I have purchased a data plan through AT

How do I get my IPad to show up in wifi networks? I purchased a data plan and have looked through settings but cannot find even using other networks setup.

Wifi is not the same as a cellular data plan.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

My iphone wifi data from the consolidated file shows more wifi networks than I have been exposed to. Does the iphone also collect location on wifi networks that are within reach of the wifi networks it has access to?

I took out the wifi location data from the consolidated file and plotted into google maps. Clearly, not all those wifi networks are in areas or really close to areas I've been to, yet somewhat close. Does it mean that if I am within a range of a wifi network my iphone will not only collect location data of that particular wifi network but also all others that are within reach of that wifi network and so forth?

How do I share wifi data between iMac and windows based computer on wifi network?

I have an unsecured wifi network at home and need to easily share photos between computers> I have an iMac and a couple window based computer> Is ther an easy way instead of using a thumb drive?

Since photos are typically large files it will probably be quicker with the thumb drive. The other way is to set up sharing where the files are located and directing the other computers to look there.

HT204291 Airplay and mirroring not appearing on iPad Air, all devices up to date. Connected to same wifi network.

Airplay and. Mirroring not working, all devices have airplay turned on and same network.
Tried hard reboot of device as well.

The reply you received did not work for me.
If you don't mind having to re-enter your WiFi password(s) there is a much simpler single step solution that will probably work more often and more reliably than all the steps listed in your other solution.
Simply go into your iOS device settings -> reset -> reset network settings
the device will reboot, and you will have to manually reconnect to your WiFi network - and any other WiFi networks that you had previously stored for automatic connection.

How do I get a Windows PC to access the wifi network?

I have a Time Capsule, I curently have a Mac Mini, a Dell Dektop, a MacBook Pro, and an iPod connected to the wifi network. I am now attempting to connect a brand new Windows 7 Toshiba Satellite and a Lenovo thinkpad. The new laptops recognize the wifi network but will not transfer any data, therefore they cannot acccess websites....
What could possibly be the issue...?

Ok, this validates that the PC is at least negotiating with the Time Capsule and can find the TC's DHCP server to get the proper IP addresses.
Let's go to the last phase of the troubleshooting to find out where the communication break is between the PC and the Internet site.
This time we are going to rely on the trusty Ping tool:
Since you verified that the PC is getting the proper IP address information from the TC, we can skip the first three levels of Ping tests: loopback, local computer, and LAN-side of the TC.
The next in line for the Ping test would be the Default Gateway. This would be your ISP's Gateway router. To know what to Ping you may need to go to one of your other devices that can successfully negotiate its way to the Internet. You can get the Default Gateway info from the AirPort Utilty. AirPort Utility > Select the TC > Manual Setup > Internet > TCP/IP tab The Default Gateway = Router Address
Ok, now go back to the PC, open a Command window, and enter the following at the command prompt: ping <IP address of the Default Gateway> If the ping fails, there is either an issue with the TC or the ISP's Gateway router. If the ping passes, go on to the next step.
Ping the IP address of the remote host. That is, instead of using the URL (like www.google.com) use the actual IP address of the website. If you don't know the site's IP address, go back to your Mac, and then, use the Network Utility's Lookup option. Enter the URL of the site, and then, click on Lookup. You should find the site's IP address in the information returned in the panel's results window. If the ping fails, the remote host may not be responding. Try another host just to be sure.
Finally, ping the URL of the remote host. This time instead of the IP address go ahead and use the site's URL. As an example, enter the following at the command prompt: ping www.apple.com If the ping is successful, you're done and the computer can successfully negotiate all the way to the remote host. However, if the ping fails, then the issue is either there are no DNS servers configured or none could be found to translate the URL to the appropriate IP address to "find" the website.

IOS 8.0.2 on iPhone 4S crashes WiFi network

Question:
Has anyone seen problems with their WiFi network associated with iOS 8.0.2?
Background:
I installed 8.0.2 on my iPhone4S and it appears to crash my entire home WiFi. I have 4 iOS devices in the house: iPhone 5, IPad, Apple TV and iPhone 4S. Only the 4S has IOS8.0.2. Since I installed it this morning my WiFi has been continuously crashing, making it impossible for the 4 Windows laptops in our house to stay connected. I left the house for 2 hours and things went back to normal. When I returned, the network immediately crashed again. I turned off WiFi on the 4S and power-cycled the router. The network came back up. When I restarted WiFi on the 4S, it crashed. Turned off the 4s's WiFi again and reset the router. Everything has been fine now for 30 minutes. I have Frontier Communications FIOS with a MI424WR-GEN3I router. Throughout all of the outages, the wired/Ethernet functionality of the router has worked fine and I have been able to access the Internet via Ethernet.

Sorry, but that's just a ridiculous thing to say. The fact that an issue is intermittent or dependent on other variables does not mean its not an issue. You have provided an opinion with no data and no help. If you can't contribute to a solution, please abstain from this thread.
If a device on a network can crash a router/WAP, the issue is with that router/WAP is there is no "crash the network" command within the Wi-Fi protocol.
That's why there are networking standards; if properly adhered to they dictate what will occur when commands are received and commensurately, the only things that will happen.
Feel free to fill out the form and peruse the actual specifications of the protocol yourself if you so choose; there's no "crash network" option.

Whether the router is Apple's or another vendor's, it needs to be able to deal with whatever traffic/commands are sent to it.

Data vs. Wifi conflict

Everytime i connect to my wifi network, it works for the first few minutes, and then all of a sudden, all apps stop responding to the wifi connection ( even though connection is still there with full bars). It just shows the loading circle on any app ( e.g. bb world) and nothing loads.
When i turn off my data services and use the wifi only, everything works smoothly with no problems.Same thing with data when i turn the wifi off. They can't seem to function simultaneously.
I called my carrier ( Fido) and they changed my data from bb data to regular data, hoping to fix the issue, but it didnt.
I use a DIR-615 Dlink router. It is not the router because my family uses iphones and androids and they are always connected to the wifi with no problem.
What is the issue here? Is it the device? or Fido?

Hey BBrickk,
Welcome to the BlackBerry Support Community Forums.
Thanks for the question. Can you please provide some more information about your issue?
1. What is the current software running on your BlackBerry Z10? This can be found: System Settings->About->Category: OS->OS Version
2. Does this happen on other WiFi networks or just the one described in your question?
3. Has this ever worked?
I look forward to your response.
Cheers!
