IPod wireless connection

Is it possible to require a password for each time my son connects to our wireless internet connection on an iPod touch 4G? Thanks!

no.

  • MacBook loses wireless connection when iPod touch connects to network

    hi
    ever since upgrading to 10.5.5. on my MacBook i've had the "intermittent network connection" problems that have been described and discussed (without any real solution from what i can see) in another thread.
    PROBLEM: every couple of minutes my MacBook loses connectivity to the network - the AirPort icon still says that i'm connected, albeit with one less bar than before, but i can't connect to anywhere, not even to the wireless router - and to re-establish a connection i need to switch off AirPort, switch it back on, it will then reconnect, and after two minutes or so i have to do it all over again because the network connection drops again.
    NOVEL OBSERVATION 1: reinstalling the 10.5.5. combo system updater helped somewhat. i used to get an error in system.log about there being too many state transitions on the wireless network and about network traffic reduction measures being taken to overcome this problem, but after reinstalling the 10.5.5. combo system updater this message never appears in the logs and I get kicked off only sometimes (see what i say in point 2 below)
    NOVEL OBSERVATION 2: now my MacBook will only lose its connection to the net if i switch on my iPod Touch and switch its wireless interface on. in fact, the only way to avoid the MacBook getting constantly disconnected is to make sure that the wireless interface on the Touch is switched off in the Touch's system preferences; if I just sleep the Touch (top button) without switching off its wireless network interface first in its System Preferences, then the MacBook will keep disconnecting even while the Touch is in sleep mode (presumably the Touch keeps polling the network or something, even while it's in sleep mode).
    DIAGNOSTIC NOTE 1: I have another wireless device (my Nokia E51, which has wifi capabilities) and if I connect it to the wireless interface then the MacBook's connection isn't dropped - i.e. the MacBook only loses its wireless connection when my iPod Touch connects to the wireless network.
    DIAGNOSTIC NOTE 2: I have upgraded my wireless router (before I had a Linksys WRT-54GC, now I have a Netgear WGR614v9) but that has made no difference.
    DIAGNOSTIC NOTE 3: I have also tried altering the router's settings (i have played around a_lot with this, trying every combination I could think of - e.g. staple down particular devices to particular ip addresses, use only 802.11g versus automatic b/g, etc) but that has made no difference either.
    RANT:
    The only thing that prevents these disconnections from occurring is to keep the iPod Touch's wireless switched off, which ***** because if I'm in the kitchen I can't have it switched on to monitor my email (yes, I've no life, i hang around waiting for emails), or if I go have a lie down and want to check out stuff on the net, or to browse the iTunes music store or whatever, then I know that my connecting my iPod Touch the computer will be disconnected.
    This obviously *****, right? And a lot of people are having wireless problems with their MacBooks, right? And these problems seem to have been around for over a year, right?
    So why hasn't Apple solved this problem yet? Or am I just being melodramatic?
    Your thoughts on any or all of the above, or flames if that's your preferred method of communicating, are invited. =)

    Having the same problem here. As a first time mac user, Apple has certainly made a bad first impression.
    For me, the issue seems to occur when transferring files between computers that are connected to the same access point (when transferring files from wired computers on the network there is no issue). My vista laptop and every laptop I have tried has worked perfectly fine with this access point so I am 100% convinced it is the mac. Basically when I copy the files, after about 100mb, I am unable to access anything on the local network or internet until I restart Airport. The weird thing is that even though I am unable to access anything, the airport utility says it is connected. I might also note that the wireless signal strength is full.
    If I can't get this figured out in a few days, this computer is going back to the store where it came from and I will officially label myself anti-mac. This type of issue is just unacceptable for something so main stream.

    Does the iOS devices connect to other networks?
    Does the iOS devices see the network?
    Any error messages?
    Do other devices now connect?
    Did the iOS device connect before?
    Try the following to rule out a software problem:                 
    - Reset the iOS device. Nothing will be lost
    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Power off and then back on the router
    - Reset network settings: Settings>General>Reset>Reset Network Settings

    Since both iPhone and iPod stopped connecting I suspect a problem with your network.

  • IPOD To Wireless Connection

    Merry Xmas to ALL-
    Son has a new IPOD touch and is trying to connect to wireless connection in the house.The Ipod asks for the password to this connection, I have forgotten it. What can I do?
    Many thanks.

    You must reset your router.
    Depending on the model you have, the process will be different.

    Can I connect ipod touch 4G to MacBook Pro with wireless connection instead of wired connection and sync to iTunes on MacBook?
    IPOD iOS 4.3.3
    MacBook OS X 10.6.7

    Yes, but you have to make some adjustments first.
    1. Make sure you are running Itunes 10.5
    2. Upgrade your ipod to IOS 5
    3. Follow the steps found here: http://www.pcmag.com/article2/0,2817,2394626,00.asp

  • My iMac is able to use my wireless internet from my airport extreme, however, no other devices(iphone, ipod) will connect. The network shows up, but the indicator just spins without ever joining.

    My iMac is able to use my wireless internet from my airport extreme, however, no other devices(iphone, ipod) will connect. The network shows up, but the indicator just spins without ever joining.
    I have tried resetting my airport extreme, creating a new network, etc nothing seems to work.

    I have a feeling you may be stuck in bridge mode there...
    Factory reset the Extreme (so we don't second guess later), and re-set up the extreme using iOS5 on your iPhone.
    Set up your Wi-Fi network with your iPad, iPhone, iPod touch, or Mac.

  • How to secure wireless connection with additional laptop and ipod touch.

    Hello,
    We are new to Mac and struggling with internet security. 
    We have a wireless internet dongle that connects into a USB port and some days our ipod touch can connect other days it cant, I am never prompted for a password to connect.  This morning we were setting up a new laptop for our daughter and it found our wireless network and informed us it was unsecured. So we assume anyone within range is utilising our wireless connection.
    If I turn on firewalls it shuts off everything, if we look at airport we get even more confused.
    Is there a simple way to resolve this so our internet connection is for our house only and new devises that try to connect need to enter a password.
    Thank you for your help!

    Describe the equipment in your network. Modem? Router?

  • I get wireless connection but my internet does not work on my ipad 2

    I get wireless connection but my internet does not work on my ipad 2

    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

  • Not the average problem with wireless connection. Please help me..

    I've been having wireless connection problems ever since I upgraded to Verizon FiOS from Verizon Wireless. Before upgrading to Verizon FiOS in the fall of 2012, my brother's laptop connected just fine with the connection. After upgrading to Verizon FiOS, my brother's laptop could not connect to the internet. It showed the wireless connection signal as Excellent, but I could not access the internet. Either it would be extremely slow or there would be no connection at all. Also, the router would sometimes restart itself randomly, and it was extremely annoying for me since I am hardwired with my desktop.
    This was weird because my iPod Touch connected perfectly fine to the wifi. So I thought it must be the laptop. But I brought the laptop over to my cousin's house, who also happens to have Verizon FiOS, and the laptop connected perfectly fine. I called Verizon and none of the technicians knew what the problem was. We tried disabling and enabling the router, changing the channels, and anything that was on the list. They couldn't help me and I was extremely disappointed because not only am I not accessing the internet with my brother's laptop, but I am also paying for the service too. The last technician I called in 2012 decided to send me a new router. I hoped this would work, but it did not. This router, too, would completely reset itself numerous times before settling down and letting me use the internet.
    I gave up after that. But in the spring of 2013, I got really fed up with the service I was receiving and I decided to call Verizon again. Again, Verizon tried to help me fix the laptop with their tools and solution guides. But nothing good came out of it, so I decided to ask for a technician to come to my apartment to fix it. We scheduled a day and I was pretty excited since I was almost positive that the connection for the laptop would be fine by then.
    I was wrong. The technician came and only stayed for about 20 minutes. He said it must be the laptop or it must be that the walls are too thick in my apartment. But that can't be it since, in my cousin's house, the router is on the second floor and my brother was using his laptop on the first floor. So it couldn't be the laptop nor the house. So we came to no conclusion. He just attached a mini router to the laptop and hardwired it. I wasn't so content but I was glad my brother could finally use the internet now.
    About three months pass by and I decide to get myself a new laptop. I get it and I am hoping the wireless connection works. It did, so I was almost positive that it was my brother's laptop that was the problem, not the wireless signal. I go on vacation for a few days and I connect perfectly fine at my friend's house. When I return home and try to connect to my wireless connection, it didn't work!
    At this point, I am extremely frustrated. I decided to call Verizon again to replace my router because it was being extremely annoying. It kept resetting itself and I was tired of it. I replaced the router, and this is the router I currently have, but I STILL have the same problem. It resets itself on its own time and I hate it because I'm always in the middle of something. Wow, just wow. There is nothing they could do to help me fix this. I call up a technician, for the millionth time, and he tells me he can't access my router. This occurred with the previous technician who sent me the new router. He tells me his tools are not working and tells me he'll call me back the next day.
    It was the next day and I did not receive any phone call. I am extremely disappointed in Verizon FiOS' service and it's customer service. I leave it alone and I just hardwire my laptop to the router. Of course this works, but what's the point of having a laptop when I have to keep it hardwired on my desk? After a day or two, I decide to check if the wireless connection works, and it did. I was surprised. But every now and then, it would shift on and off. Most of the time, the wireless connection is either EXREMELY SLOW or I get none at all, nonetheless, it still says the connection is Excellent.
    Please, if there is anyone who could help or try to help me, I would most appreciate it. If there is more information that you need, ask me and I will try my best to provide it to you.

    Admittedly, that IS a strange case. Unfortunately, it sounds like all possible troubleshooting has been done by the tech support agents. you mentioned that you were dissatisfied with your other service, did it have a similar problem? theres a possibility of dirty fiber or a bad ONT port, but the random rebooting of the router would almost exclusively be a bad router. question: is the router in the same location as before?

  • I lose wireless connectivity when I connect the nano to my PC

    I have a DSL modem connected by ethernet cable to a Linksys wireless router. My PC has USB linksys antenna. The wireless connection works fine except when I plug in the Nano, it takes about two seconds and I lose the connection to the router. If we are in itunes downloading it is suspended. If we are on the internet the next click and the Microsoft "you are not connected to the internet" page comes up. To reestablish the internet connection I have to remove the nano and reboot the PC. Needless to say this is very frustrating.
    If I reboot with the cable attached I get an error unable to run an ____.exe that I believe is the antenna setup because the linksys monitor stays gray in the startup box.
    I have tried to move the antenna to a different USB port on the PC with no luck. Everything else runs fine.
    Does anyone out there have any ideas/fixes? - Your assistance is greatly appreciated!

    thanks deggie for your answer.
    I had my ipod with autosync off ... I set it "manage like disk" .
    I try to recover the music with 2 programs: "ephod" and "copy trans" ..
    I can see all the songs listed, but can´t backup to disk or recover them......  
    I see than my ipod hasn´t the folder  "ipod_control" , which appears before I had this problem....
    Any idea ??? Thanks again.

  • HP Officejet 6500A Plus will not maintain wireless connection reliably

    For the HP EXPERTS on Expert Day, April 18, 2012:
    B.L.A.T. (Bottom Line At Top):  We have an HP Officejet 6500A Plus purchased about 5 months ago.  We wanted to use it as a wireless-connected printer in another room besides our home office.  It is useless to us because it will not maintain its wireless connection, even sitting just a few feet from the router in the same room.  Except for numerous hours of troubleshooting, we have left it sitting powered up, but unused and idle, for almost the entire 5 months in our home office.  DURING ALL THAT IDLE TIME, IT HAS LOGGED OVER 3,200 DISCONNECTS, at a consistent rate of 24 disconnects every 24 hours, even though it ALWAYS reports that the wireless signal quality is “EXCELLENT” (all this is according to the Wireless Network Test Reports we’ve printed throughout the last 5 months).  So our question is, what is it that this printer is trying to do once an hour over a wireless connection that is causing these thousands of disconnects?  And how can we stop it?
    NOTE!  Before you round up the usual suspects (namely our router and our PC firewalls) please note that we also bought an HP Officejet Pro 8600 Plus ON THE SAME DAY as the Officejet 6500A Plus.  The 8600 was also installed with a wireless connection, and has worked without a single network issue for the entire 5 months.
    NOW, FOR THE REST OF THE STORY…
    WHO WE ARE:  My wife and I have worked on HP equipment for 33 years, starting in 1979 as corporate customers of HP when we worked for Exxon; then we both worked for HP directly for 17 years; and we’ve now used dozens of pieces of HP equipment in our home during the last 12 years in retirement.  We’re primarily software folks, so we’re not exactly experts in hardware and networking, but on the other hand, this ain’t our first rodeo either.
    OUR CONFIGURATION: 
    PC’s – All running Windows 7 x64 with all important patches applied and Norton Internet Security 2012:  HPE-270f and HP AIO 200-Quad, each with full 6500A and 8600A drivers installed on wireless connection.  These 2 PC’s themselves can connect either wirelessly or via Ethernet to our home network.  The 270f has a dual-band wireless board.  Both bands work.  We also have a new dv7t laptop with only the full 6500A driver installed via wireless connection.  The laptop is now upstairs and it’s connected to our home network wirelessly without any issues.  (This is where we had hoped to also put the 6500A, but it needs to work reliably via wireless connection.)
    ROUTER:  Netgear N600 WNDR3700 providing Ethernet and wireless networking.  Router provides a very strong wireless signal throughout the house.  No wireless problems with any other equipment including an iPod, two Kindle Fires besides all the HP equipment.
    PRINTERS:  Besides the two HP printers, the HPE-270f PC has a Canon MP960 installed on it.  And if we can’t get the 6500A working right or replaced with something that does work right, we may be buying our second Canon printer.  By the way, on the 6500A, ePrint and App’s are set to ON, but of course they’re not being used, just like everything else on this AIO.
    OTHER:  We also have a Sonos music system that connects to our network via Ethernet and has its own proprietary mesh network (on another frequency) for transmitting ripped music wirelessly to speaker units throughout our house.  (If you aren’t familiar with this totally cool system, check out sonos.com).  We’ve never seen any evidence of interference between these two wireless networks, or our wireless phone sets either.
    HP TOOLS AVAILABLE ON ALL 3 PC’s:  HPU
    UPDATE 5.003.001.001 (reporting everything up-to-date); HPHDU 3.1.0.17; HPPDU 5.0.0.015 and HPNDU 4.3.0.002. 
    SYMPTOMS:  The 6500A Plus installs quickly and easliy, and connects wirelessly just fine during installation.  But sometime over the next hour (usually less), it disconnects and won’t print from PC applications.  Sometimes the application puts up an “Unable to communicate with printer” screen, even though the PC usually thinks the printer is “ready”.  Other times, the PC thinks the printer is offline (but printers don’t have “offline” buttons anymore!).  Often, if you just leave everything alone, the 6500A will somehow reconnect and print out the spooled file 5-30 MINUTES later.  So it does usually seem to be able to recover given some time, but that doesn’t always fit our schedule!   Occasionally, turning the wireless radio on the printer off and back on will fix it right away.  But usually, you have to power the printer completely off, and then back on.  As far as we know, that always fixes it…..until the next disconnect a few minutes later!
    PREVIOUSLY TRIED:  After reading some of HP’s wireless network support websites, I manually assigned a fixed IP address to this printer.  It didn’t seem to matter; according to the wireless network test report, it still logs disconnects at the rate of one per hour, and all the failure symptoms were the same.
    We also dabbled a bit with setting this printer as “trusted” to the Firewall, but that didn’t seem to matter either.
    Next, we connected the printer via Ethernet.  The printer immediately started to work, even though it had just been in its “failed” state over the wireless connection.  As far as we know, it never failed while connected via Ethernet.  This seems to point to a purely wireless hardware/firmware problem on the printer itself.
    Late last year, I tried two different chat sessions about this with the inter-continental AIO support teams, each one lasting several hours.  Unfortunately, none of their optimistic solution scripts seemed to fit our problem.  They both seemed determined to reconfigure the 6500A as a TCP/IP printer, which of course worked fine initially, just like everything else.  At this point, they would understandably want to close the chat.  But 20-30 minutes later, we could no longer print to it.  During the second chat, they got into one of our PC’s remotely and effectively turned off the spooler (by selecting “Print Directly” or something like that).  After that, all was well again (as usual) UNTIL the printer disconnected, at which time attempting to print from that PC would HANG the application (since the spooler was no longer buffering) and eventually hang the whole PC.  One giant leap backwards.  That’s when I gave up on the multi-hour chat sessions.
    The three diagnostic utilities (HDU, PDU, NDU) have been tried over and over.  When the printer is in its disconnected state, the DU’s usually don’t detect the 6500A at all, or if they do detect it, they are unable to fix anything.  Frankly, it’s easier to just power the printer off (which takes about a minute) and power the printer back on (which takes more than a minute) and then wait for the spooler to kick in (usually about 30 seconds).  BUT WE DON’T CONSIDER THAT A SOLUTION!!
    B.L.A.B.  (Bottom Line At Bottom):  We have used up nearly the entire black ink cartridge and at least a ream of paper troubleshooting this brand new printer, to no avail.  This printer is useless to us unless it can maintain a wireless connection reliably.  Please help!
    Thanks –
    Bob and Jane

    I bought the Officejet 6500A Plus about one month and have experienced the very same problem. I tried to remedy this problem following suggestions in a number of different posts (static IP, router, firewalls etc), all to no avail. Last week I called support. The support I received by the tech over several hours and different days for a week was very good. However none of his suggestions corrected the connection issue. After today's recommended fix failed, he advised HP is aware of this issue with the 6500 and other affected printers. He claimed HP was working on a firmware upgrade. He did not know when the update would be provided. The tech also claimed HP acknowledged this problem in a written announcement. He agreed to email the announcement to me. I haven't received it. This has been the only problem I've had with the 6500

    My guess is that the security settings on your router and iPod do not match.
    For a test, change your router so there is no security.  See if you can connect and get to the Internet. If that works, set up the router with security and use the same settings for the iPod.

    Highly interesting is the post of J.Exby which i reproduce here:
    For months I've not been alone in holding to the notion that the airport client software on Mac OS X 10.4.x has been problematic and unstable in certain (noisy, crowded, channel overlapped) wireless environments. Issues littered around the Internet Mac forums include problems of networks appearing, then disappearing. This is a difficult problem to pin down, given the difficulty of reproducing the conditions that might cause wireless network dropouts.
    A major symptom of the problem was seeing the constant messages of:
    "An error occurred joining the AirPort network" (Try Again) (Cancel)
    when attempting to connect to a wireless network, despite that network being seen, having correct security settings, etc.
    Various temporary fixes/ideas floated around the mac community have included:
    - reseting pram, nvram and PMU
    - installing 10.4 from scratch, instead of 10.3 to 10.4 upgrade process
    - Repairing permissions, run Combo updaters, etc
    - putting system to sleep or reboot for temporary connection fix
    - applying AirPort 2005-001 patch (or not)
    - upgrading (or downgrading!) AirPort basestation firmware
    - changing AirPort channels
    - enabled (or disabling) Interference Robustness
    - disabling Bluetooth and BT peripherals
    - removing WEP/WPA passwords out of Keychain
    - running Keychain First Aid on user/login keychains
    - buying new AirPort extreme cards
    - replacing AirPort base stations with other vendor hardware, etc.
    With the stability of our Windows XP clients now (after driver updates) and the change from Apple base stations to Belkin Wireless Pre-N Router having no appreciable benefit for our Mac notebooks, the OS X AirPort client software suspicions only grew.
    During troubleshooting I always have
    Applications--->Utilities--->Console
    and
    iStumbler (96)
    running, and I watch output as wireless scans are performed.
    From the Terminal I also run:
    /System/Library/PrivateFrameworks/Apple80211.framework/Resources/airport -s
    and usually see constant
    AirPortScanner WirelessScan error -2013261821 airpInternalErr
    messages.
    After two days of testing (and fixing?) I am even more convinced there are bugs in the powerpc 10.4.x AirPort Extreme Framework!
    This is what I found:
    Environment at our office:
    - wireless Network A (802.11g channel 1, WPA personal)
    - wireless Network B (802.11b channel 6, WEP 40bit ascii)
    - wireless Network C (802.11g channel 11, WPA personal)
    (WAR-marching around our office exterior shows at least 12 outside wireless networks found at various signal strengths!)
    Test systems used:
    - iBook G4 (10.3.x and 10.4.5)
    - Powerbook G4 (10.4.5)
    - Intel iMac (10.4.5)
    Primary symptom on iBook: networks not displaying long enough under the AirPort icon/menu (or Internet Connect) to connect to ANY network reliably! Perhaps connect to Network A intermittently, never even see Network C.
    iStumbler showing some networks respond to poll, then immediately stagnate/disappear.
    Primary symptom on Powerbook: stable connections to Network C most times, difficulty "switching" to Network B or A once moving closer to source. Usually stable "seeing" networks via AirPort menu icon, but still have occasional dropouts (due to fluctuating signal strength or interference?).
    Primary symptom on Intel iMac: NO PROBLEMS! Can connect to (and steadily "see") all valid Networks A, B, C !
    iStumbler constantly polls all available networks, with no dropouts.
    Steps taken:
    1. Wipe iBook hard drive, install 10.3 from dvd. AirPort signals unreliable.
    1a. Perform all 10.3.x Software updates, Repair Permissions, reboot. AirPort still unreliable.
    2. Reset PRAM, nvram, PMU. no improvements.
    3. Reseat AirPort Extreme card, ensure antenna is firmly plugged in. AirPort still unreliable.
    4. Wipe iBook, install 10.4.3 "fresh" from Full retail version DVD. AirPort still unreliable.
    4a. Perform all 10.4.5 Software (combo) updates, Repair Permissions, reboot. AirPort still unreliable.
    5. Hold down the Option key, and click on the AirPort icon in the menu bar.
    select About AirPort...
    pay particular attention to each system showing:
    iBook: AirPort Framework 421.13.0
    powerbook: AirPort Framework 421.13.0
    intel iMac: AirPort Framework 426.1.0
    Aha! A big difference with the AirPort Framework component version on the Intel iMac!
    6. So, using the Terminal let's get this newer Apple80211.framework onto the iBook.
    First on the intel iMac:
    cd /System/Library/PrivateFrameworks
    sudo tar cf ~/intelApple80211frame.tar Apple80211.framework
    Copy this intelApple80211frame.tar file onto a USB thumb drive, CDR, iPod, scp, etc. to copy it onto the iBook (home directory).
    7. With the tar file copied into the home area on the iBook, turn off iBook's AirPort via the menubar icon.
    Now launch Terminal and:
    mkdir backup-framework
    cd /System/Library/PrivateFrameworks
    sudo mv Apple80211.framework ~/backup-framework/
    sudo tar xvpf ~/intelApple80211frame.tar
    Launch Disk Utility, Repair Permissions on boot drive.
    Reboot iBook.
    8. Turn Airport on via the menubar icon.
    iBook now has HUGE improvements in wireless connectivity! It can "see" all Networks A, B, C reliably and can connect to any of them when in range (having enough signal strength). Switching between networks is successful 90% of the time. Occasional message of:
    "An error occurred joining the AirPort network (Try Again) (Cancel)"
    usually works after clicking (Try Again), whereas before Try Again almost always failed.
    I am unsure how this newer Apple80211.framework will affect future Software Updates on the iBook, but frankly I could care less now that it's able to access all of our wireless networks!
    I am unsure if this is the magic-bullet solution for a majority of people, but I'm stunned that Apple appears to be providing new and improved Apple80211.framework software with the intel iMacs, but many of us have been fighting AirPort problems on PowerPC platforms for months!
    Come on Apple, OS X 10.4.5 should contain the SAME software component versions for ALL CPU platforms!
