Connect Midlet through Wifi network

Hi All,
I am trying to create an application, the mobile only supports Wifi network. I facing connection problem, the MIDlet is not able to find the server mentioned in DatagramConnection.
1) Does J2ME supports Wifi, or who is the relation build
2) Is the approach correct?

I'm a grad student with a limited buget.
I have a 4G hotspot that I use to place/recieve calls using an ipod. But I only get a limited amount of data for free every month. Sometimes at school I like to connect my computer to the hotspot so I can use the connection to sync my ipod with itunes (the university won't allow me sync over their network).
But if I forget to switch back to the university's network when I need to use the internet, I'll quickly use up my free data, and I'll be stuck without a phone for the rest of the month (at least when I'm away from a wifi connection).
Could I disable my computer from acessing the internet only when connected to the one device without affecting its performance when conected to any other network?

Setting up new ipad 2. Won't accept my PW for my Airport Extreme (Wi Fi network?) Where is the PW for my WiFi? I am stymied. Can I set up through My MacBook Pro, which IS connected to my WiFi network?

Setting up new ipad 2. Won't accept my PW for my Airport Extreme (Wi Fi network?) Where is the PW for my Wi Fi? I am stymied. Can I set up through my MacBook Pro, which IS connected to my WiFi network?

If you could provide the make and model number of the modem that the AirPort Extreme will be connecting to, we can likely tell you a bit more about what to expect in the way of getting the AirPort set up and working.
Unfortunately, "plug and play" does not apply here. You will need to set up and configure the AirPort Extreme using your iPad or iMac to name the AirPort as a device, assign a device password, name the wireless network, assign a device password and a few other things.
Once the AirPort Extreme is set up, you can connect the PC to one of the LAN <--> ports on the AirPort Extreme using an Etherent cable.
The iPad and iMac will connect to the wireless network that the AirPort Extreme provides.

Deskjet 3050 not connecting to my wifi network

Accidentally pressed Restore Default and my printer will not connect to my wifi network. How do reinstall it please?

Hi @Rotini
A full feature driver for Yosemite is not available for your printer, either from the CD that shipped with your printer or from the HP website. This document applies to HP printers supported in Mac OS X versions 10.6 (Snow Leopard), 10.7 (Lion), 10.8 (Mountain Lion), 10.9 (Mavericks), and 10.10 (Yosemite) that only have drivers available through Apple Software Update.
With that being said, I can help you put the printer on your wireless network without software. I use this method for iPads, iPhones and other devices that do not have software.
Restore the network defaults on the printer by pushing the wireless button, going to settings, and then restore defaults. The wireless button should then start flashing, this means it is now in autowireless mode.
Connect to the network that the printer is broadcasting. It is usually HP-setup-3050a and then part of the MAC address. The wireless light will still be flashing on the printer at this point, this is normal since this is not an actual adhoc connection.
Load up the Embedded Web Server (EWS) in the browser on your mobile device. The default IP for autowireless is 192.168.223.1.
Go to the network tab along the top of the EWS.
Click on Wireless Setup Wizard along the lefthand side to begin configuring the printer.
You have now completed the Wireless configuration, follow the next 3 steps to start printing.
The blue wireless light will go solid, put the Mac back on your own network.
Add the printer to the System Preferences.
Print

My Apple Tv is connecting to the Wifi network but is not connect to the internet. So when I look for it on my Airplay it doesn't come up. I have 3 other ones already working on the network and they are all fine.

My apple TV is finding and connecting to the Wifi network but then says it is not connected to the internet and then I cannot find it on the iPad through airplay. I don't want it connected to the internet (as in www.) because for the use I have I only need to use the Apple tvs locally in a sports hall as scoreboards. I have 3 others working on the same router and they are working fine (as of yesterday)
On my screen I see (obviously not written like this)
network connect- yes
signal strength- fine
Ip address- fine
DCN- fine
Activation- Failed
This is the only negative I can find and the statement that the Apple TV has connected to the wifi but is not connected to the internet.
Where has it gone wrong for me. Please help

It is not properly connected to the network.
Make sure location is set correctly
DNS should be on auto (settings - general - network)
Try ethernet
Signal strength on device won't account for issues, you would need a network report from istumbler, netstumbler or similar. This will show accurate signal strength along with noise and nearby networks

Mac NOT automatically connecting to preferred wifi network

Hi,
I am facing a problem with OS X 10.9.1 (Mavericks) wifi connection.
I use a Time Capsule as a base station and 13" Macbook Air (2012). The base station is connected to the internet through a PPOE connection.
Here are the details.
Since upgrading to OS X 10.9.1, my Mac automatically connects to preferred wifi network ONLY WHEN the wifi is available at start up or when the Mac wakes up from sleep, but NOT OTHERWISE.
Before the upgrade, the Mac automatically connected to the preferred wifi network not just at start up, but whenever the wifi became available.
In other words, after the upgrade, if I boot up the Time Capsule base station and the Mac simultaneously, the Mac scans for the base station wifi network (this is configured as the top preferred wifi network) at start up, but since the base staion is still booting up, the Mac doesn't find the wifi.
But once the base station has booted up and wifi is available, the Mac no longer bothers to join it. At this point, the Mac is also not able to do Time Machine backups to the Time Capsule because it is not able to locate the Time capsule disk over the wifi.
This situation remains (i.e., the Mac being not connected to the wifi) unless I do ONE of the following:
1. I manually select the preferred wifi network using the wifi icon at the top of the screen; OR
2. I put the Mac to sleep (by closing the cover) and then wake it up. On wake up, it connects automatically to the preferred wifi network; OR
3. I turn of the wifi (using the wifi icon on the top) and turn it back on, at which point, the Mac automatically connects to the preferred wifi network.
I have tried everything possible including contacting Apple support, but so far the issue is unresolved.
Appreciate any help you can provide.
Prem

I have had wireless problems intermittently for a year, and seriously for 6 weeks. Apple denied the issue and was no help in spite of many tens of thousands of people on their own discussions complaining. I found a post suggesting a couple of things which fixed the problem. I don't know if both are necessary, but the first by itself does not solve the problem.
Lock the channel of your router to channel 1, apparently Apple and 802.11n don't play well together on higher channels. When this becomes a standard this will be resolved I hope.
Open your network preferences, select 'airport' and advanced. Delete unused networks. Select your network.
Open TCP/IP and write down all the settings, configure iPv4 manually. Enter the settings manually. Turn off IpV6.
Open DNS and write down your DNS server. Delete it and re-enter it manually.
This has worked on 2 macbooks and an iMac for the last 3 weeks with no network drops.

Cannot connect to my WIFI network since updating to IOS 7.0

Since updating to IOS 7.0, I have been unable to connect to my (or any) wifi network.
I have tried every suggestion / help from the forums / web searching.
I have tried different wifi connections (all the same - unable to connect to network).
Waited for the 7.0.3 to see if this has fixed the problem, but no..
I'm extremely frustrated and would like Apple to help.. I'm not the only person with this problem - and I haven't seen a single response from apple regarding this.
Since I am now out of the 1 year warranty - I will be pursuing this through the 'sale of goods' act in the UK if I don't receive a satisfactory response - I expect my device to last longer than a couple of years and consider the ipad broken as a result of the update...
Have been very happy with my apple devices up to this point, but loosing patience now!

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.
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.

How can i connect to a wifi network with no internet connection?

I used to be able to connect my Z10 to a wifi network even when the network had no Internet connectivity when i got my phone in Feb. 2013 (10.0) However ever since the 10.1 update this has stopped working. I cannot connect to my wifi network when there is no Internet connection. I cannot play videos / music from my phone to my tv/music system or connect to my laptop. However my laptop and tv communicate just fine through the same network.
Can anyone recommend anything for this?

Your saved wifi networks should connect automatically whether internet is available or not, you may receive a notification "there appears to be no internet connection".
Update to 10.2, if not available from your carrier then use Sachesi (see other threads).

When i click on safari to use the internet it says "safari cannot open the page because it is not connected to the internet", but i am connected to a wifi network so how do i get safari to work?

you may be connected to the wireless network but the question is the internet working properly on the wireless network...
what i mean is that i can make a wireless network without the internet so i can save and share files and have other devices connected to the same network access them... but you have to make sure that your internet it running properly... may have to reconfigure the router is your using PPPOE or if it was working prior to your post then try to restart your modem... that usually resolves most issues.

Touch screen stopped working. Is there anyway to force a full backup of the iPhone without typing in my passcode lock or is there anyway to force it to connect to a WiFi network so the phone can backup to iCloud??

Hello all, I could use some help with my iPhone 4, I hope this is the best place to ask!
The Problem:
I want to do a full backup of my iphone to either itunes or to icloud. Unfortunately the iphone got wet and isn’t working properly. The phone turns on and still works, but the touch screen no longer works. I have a passcode lock on the phone so iTunes will not allow me to backup it up until I type in the passcode (which I cannot physically do). WiFi had been turned off before it got wet so it won’t connect to any known WiFi networks either to backup automatically to iCloud.
What happened:
I had been travelling for 6 months and went tubing on a river with my iphone in a dry bag. Unfortunately the dry bag failed and filled with water ruining my iphone.
What I’d like to do:
It’s an old phone and I was planning on buying a new iPhone anyway. I would love to do a full backup to either iCloud or to my computer so when I get a new iPhone I don’t lose anything. I’ve already connected it to my PC and downloaded all the photos and videos off the phone so at least I haven’t lost that, but I would like to be able to recover all the text messages, WhatsApp messages and notes I had created during my 6 months of travel.
The last time it was backed up to my pc or to icloud was in April, so there are 6 months worth of very meaningful data I would love to keep to remind me of my travels!
Is there anyway to force a full backup of the iPhone without typing in my passcode lock or is there anyway to force it to connect to a WiFi network so the phone can backup to iCloud??
iTunes recognizes the phone just now and I tried upgrading the phone to iOS7 in the hopes that it would first backup and then upgrade. Unfortunately all that happened is the phone upgraded to iOS7, but it didn’t backup to iTunes. Now the phone is stuck at the iOS7 welcome screen and I can’t do anything else with it.
Any ideas or tips would be welcome!
NOTE: This is NOT a jailbroken iPhone.

If there is no other way around this, is there anyway to completely wipe the phone then??
The Apple store agreed to give me a new iPhone 4 as a warranty replacement for $150 (I travel a lot and I have a factory unlocked phone, so this is still worth it for me). But before I trade it in, I would like to make sure all my data is backed up on the device first.
When I try and restore the phone now on iTunes, it says I have to turn off Find My iPhone on the phone first before I can restore it. Now since I can't use the screen I can't really do that.
So how do I completely wipe the iPhone???
Thanks!

Can't Connect to any WiFi network

I just got my iPhone yesterday and I'm already having a serious problem,I can't connect to any WiFi networks.
I can see the networks around me and I can select networks that I've setup and I know are open or I know the security passwords, I can even enter the network passwords for the ones that require them and it accepts them without complaint. When I select a network I get a little check mark next to that network which I assumes means it should be connected to that network. However, the iPhone never actually connects to them, i.e. no IP address, no router no nothing in the network settings screen for each network, and always appears to the using the Edge wireless network when accessing the internet.
I've tried DHCP and static IP but neither works.
I updated the phones software to 1.1.4, has anybody reported problems like this with this or any version of the software.
Any help would be much appriciated.
If I can't get this resolved today I'm returning to the AT&T store tonight for a new one.
Thanks
Matt S.

theevilone,
I have personally used an iPhone with routers from D-Link, Netgear, Linksys, Apple and Belkin.
Some routers, regardless of manufacturer need to have their firmware updated. Generally speaking if you look at the release notes, the same updates that resolve issues with DHCP for game systems and PDAs, also resolves them for the iPhone.
In addition hardware or MAC address filtering can cause issues where you connect to the network and not get DHCP.
Hope this helps,
Nathan C.

My ipod 5 was stolen but I have find my ipod installed on it but my ipod isn't/never was connected to a wifi network when it was stolen so how will my ipod play sound or go on lost mode and if there's no wifi connected to it?

my ipod 5 was just recently stolen in a waterpark (same with my best friend) and when i went on to find my ipod I pressed play sound and lost mode but it never successfully did all those things because my ipod wasn't or isn't connected to a wifi network as it says in the app. so how will I ever find my ipod if it never is going to connect to a wifi network without the thief accessing my ipod (I have a passcode). and also when I check the app once in a while it says ipod is online but cannot find location, so does that mean the thief is using my ipod or is trying to get in?

Yo are correct. It has to connect to internet for the FindMyiPhne features to be transmitted to the iPod
lost/stolen
No app on the iPod is required.
- If you previously turned on FIndMyiPod on the iPod in Settings>iCloud and wifi is on and connected, on a computer browser go to iCloud: Find My iPhone, sign in and go to FIndMyiPhone. If the iPod has been restored it will never show up or conbtinue to show off-line.
- You can also wipe/erase the iPod and have the iPod play a sound via iCloud.
iCloud: Erase your device
iCloud: Use Lost Mode
- If not shown, then you will have to use the old fashioned way, like if you lost a wallet or purse.
- Change the passwords for all accounts used on the iPod and report to police
- There is no way to prevent someone from restoring the iPod (it erases it) using it unless you had iOS 7 on the device. With iOS 7, one has to enter the Apple ID and password to restore the device.
- Apple will do nothing without a court order

Trying to set up my brand new MacBook Pro and it does not connect with the wifi network I have selected for this purpose. Nothing wrong with the wifi as both my iPad and iPhone are happily connected. Suggestions for connecting to the wifi network accepted

Setting up my brand new MacBook Pro and it will not connect to the wifi network. Nothing wrong with the network which is happily working for my iPhone and iPad! Suggestions accepted for making this connection.

Fixing this is a two step process:
1) System preferences > WiFi/Airport ...
... check [√] Ask to join new networks
"Known networks will be joined automatically.
If no known networks are available, you will
be asked before joining a new network."
2) Remove unwanted networks from the list of "known" networks under
System preferences > WiFi/Airport > (Advanced) > | Airport/WiFi pane ...
Close the window and save changes. If no joy, do a restart to ensure you are playing under the new rules.

Ok, well if you're sure that there are shared folders on your PC's, then try this:
Click somewhere on desktop, so you're in finder > Go > Connect to Server (shortcut to all of this is Command + K) then type in: smb://ipaddresshere
eg:
smb://192.168.1.7
Then either connect as guest, or login with the PC's (not your mac's) username & password.
