USB Modem 21M-02 disconnects after 20 sec

Hi,
I have the problem with my newly bought Nokia USB Modem 21M-02. When I try to use it with Play operator (260-06) in Poland (I try 3 different SIM cards) modem disconnects after about 20 second after plugging it into USB. During this short period I can connect with it to Internet, send/receive SMS, browse phone book. Then after about 20 seconds it disconnects, the  signaling diode becomes red fast flashing, communication with modem is not possible. I checked this modem with different computers with Windows XP, Windows Vista and MacOS and problem doesn't disappear. What is interesting the problem disappear if I change SIM card to any provided by other operator. So there is no problem with Aero2, Plus, T-mobile.
Any advice? Please help.
Is there any possibility to update firmware? Currently there is M1.7.0.

I have the same problem, but I'm using Cisco UCME 9.1
Jabber for iPhone version is 9.1.2.21344
Disconnects exactly after 8 seconds.
Please help somebody!

  • Annoyed with Apple usb modem

    I am very disappointed in the Apple USB modem and its disconnecting probelms. I called Applecare on this, and the first thing the tech said was I should have gotten the internal modem. Yes. On an iSight iMac. I had to tell him it wasn't an option.
    After a few seconds of silence, he went through a litany of things You Must Absolutely Not Do With A USB Modem. Like do not start the computer with the modem plugged in (I have no idea how one does a restart since one is also advised not to unplug it when the computer is running). Do Not unplug the modem when it is in the 'interminable disconnect loop' (I already found that this causes kernal panics which generated the call), Do Not open any applications while the modem is connecting (this causes it to immediately disconnect). Do Not plug in any USB or FW devices while the modem is running. The list went on. He also said that he would email a Kbase article on these modems and how to use them. Well, the article I got was a 2 year-old article on internal modems. No matter, it was in Japanese. No help from Applecare.
    What annoys me most is that it constantly disconnects when using any app more processor intensive than Safari. I can't burn CDs or DVDs, or any Photoshop work. When it does this, it takes at least 10 minutes to disconnect if it does it at all. I was compressing some video which still had an hour left to go when the modem disconnected. I had to wait until the compression was done, so I could do a restart and get the modem to stop.
    I am getting very upset about this. This modem should perform as well as the internal modem it replaced since the internal isn't an option. When I get back home from Christmas, I'll be calling again, but my first call was very disheartening, since it appears the tech sent me some arbitrary article to get rid of me.

    I doubt the tech sent you an arbritary article to get
    rid of you.
    The fact is that USB Modems are in fact problematic
    NO MATTER who the manufacture.
    That being said the reason the article that he sent
    you was outdated is because the technology is the
    same outdated.
    You must remember that the technology has progressed
    well behond the 56k modems of old, and yes I am aware
    that in many instances that is all one has available
    for whatever reason.
    That is the reason that the DSL was developed to get
    away from the inconsistancy of straight dial up.
    Bear in mind that the USB has shown to be unreliable
    , innconsistant, and fair at best.
    So the fact is that when the tech gave you the do's
    and the dont's of USB modem use it was so you would
    understand the problems you will face if they are not
    followed.
    Cheers Don
    He was able to give me the information regarding all the do's and don'ts over the phone, and I doubt if he pulled the info out of a hat - so why didn't he just send me what he was reading? He gave me a litany, far more than I could remember, hence the request for instructions on (what you yourself mentioned) is a faulty device. Intructions not included in the manual btw. It seems to me that if doing a certain action, like unplugging it during an unstoppable disconnect loop, causes kernal panics, then Apple should mention it. Publish it, actually.

  • Apple USB modem disconnects after a few hours??

    I bought an imac G5 -- it came without a modem. (After a false start), we bought the Apple USB modem. Now we want to upgrade the operating system, either with Safari or with "Software Update". It tells us we need Mac OS X Update to 10.4.3, and it is 97.0 MB.
    We have a fairly slow dial-up connection -- always have, so we usually download large files like these overnight. But our Apple USB Modem won't let us - perhaps it is too unstable. After 6 or 7 hours we get disconnected. (It says we need 8 or 9 hours to download the file). Our main problem is that we can't stay connected for more than 7 hours.
    I've made sure under the Network Preferences, for external modem, the Prompt every xx minutes to maintain connection, and Disconnect if idle for xx minutes, are both unchecked. I've turned off the screensaver. I make sure I move the mouse and a window every hour or so. I've phoned my ISP, and they deny a time-limit. I've tried not breating heavy near the computer.
    What else can I do? I've always been able to stay on line over-night for download with my old computer/modem, but not with this one. I've tied at least 4 times. Is there something wrong with the Apple USB Modem?
    Also, when I tried with Safari, and the modem disconnects, I thought I could just re-log on and start downloading where I left off -- but no. Every time I click the "resume downloading" circle next to the update in the download window, it starts from the beginning. -- it doesn't resume where it left off!
    That is the most frustrating part about this -- I've downloaded the first half of the file a half-dozen times, and no matter if I use Safari or Software Update, I can't get the computer to remember the hours of work it just did and simply continue downloading from where it left off. If I could just solve that issue, I could get the system update downloaded.
    If we don't solve this, we will never be able update any apple software with large files. Thanks for your help.
    Francis

    it's a 3.5 hour round trip to the closest Mac store.
    I just want my modem to work right -- the first time. Actually, this is the third modem I've bought (all on-line since I have no mac store close). The first USB modem didn't have a mac driver. The next bluetooth modem said it was mac compatable, but when it arrived, it was only capatable with os9. So I get a modem right from Apple, and darn, I just want it all to work now. I'm tired of foolin around. Why wasn't there an internal modem anyway?
    My old modems and macs could download overnight. All I want is for it to be as good as the old stuff.

  • With vodafone usb modem broadband, it takes mozilla 5 mins. to access a website;Mozilla 1.7 takes 30 secs.

    I have vodafone broadband mobile lite (USB modem) and after selecting a website, it takes up to 5 mins. to get there and open it. (and by the way, IE is the same), whereas old old Mozilla 1.7, which is what I am submitting this through, takes 30 secs, or so via vodafone.

  • Wireless modem disconnecting after 10 minutes consecutively...

    My wireless modem is disconnecting after every 10 minutes...I just replaced the modem and cable so it is not that.
    It shows as a Ethernet port connection...it is plugged into a USB port.
    Help

    Interesting. I have a Macbook pro 17" and although all is fine using either of the 2 usb ports on the left, my external modem is either very slow or disconnects for no reason when I use the usb port on the right.
    I think it may have occurred after I upgraded to 10.4.7 also.

  • I allways get disconnected when using Apple USB Modem

    Hello!
    I have bought the Apple USB Modem with my MacBook and want to use it for a dail-in connection in the netherlands (kpn). But when I dail in, I allways get disconnected. After dailing in, sometimes I can open a few pages in Firefox, sometimes only one page or not any page at all. Sometimes I can open an IMAP folder with Thunderbird, but most times I get disconnected before. When I establish a SSH connetion, it works a little bit longer, but after some time the connection is terminated too. Most times I have to wait very long (>20 seconds) until a hostname is resolved, sometimes it's quite fast, somtimes resolving fails. Especially when I try to open several websites at the same time I get disconnected very soon.
    Most times I get an error message like "modem unexpectedly disconnected connection".
    Can someone tell me where I can get more information about WHY the connection was disconnected?
    This way I cannot use the Internet, sometimes it takes up to 1 hour to come to a particular web-page (e.g. open a special mail in my web-mail account).
    Best regards
    Andreas

    Thank you! I use 10.4.7, but could not try it yet, but looks promising. Does Apple know about the problem? Will there be a fix in an update soon?
    Thanks again!
    Seems many other people have the same problem, see comments at:

  • After upgrading my Macbook Air to OS Yosemite it doesn't recognise the 3G USB modem which was working previously. Any ideas

    After upgrading my Macbook Air to OS Yosemite it doesn't recognise the 3G USB modem which was working previously. Any ideas?

    Hi ..
    Reset the PRAM > About NVRAM and PRAM
    Those instructions are for Mavericks but will work on Yosemite as well.
    Then try the USB modem.

  • All USB drives disconnect after upgrade and clean install of MAC OS X Mavericks

    I first upgraded to Mavericks and noticed that my external USB dries would disconnect after MBP Retina Mid 2012 model was updated to Mavericks.  These worked fine in all versions of Mac OS X before upgrade.  So I did a clean install figured my machine would benifit from this anyway. This did NOT fix the problem. 
    Wouldn't be much of an issue but I use this macine as a media server with Plex and all the media is in one of the external USB 3.0 drives.  All drives are from Seagate, and have found no info there.  Guessing this is a bug that Apple needs to fix unless its a Seagate issue which I doubt. 
    My TEMP FIX while my machine is plugged in to the power adapter and drives.

    If the tracks are recognized by your iPod (playable), search VersionTracker for "iPod". You'll find a number of utilities that can transfer your tracks and your playlists from your iPod back to your Mac.
    If they're just on your iPod as data, then I'm not certain since I don't use a custom hierarchy, but you should be able to copy the folder back to your iTunes Music folder, turn off the "copy to iTunes library when adding to library" preference, and then use the Add To LIbrary command to get them recognized by iTunes. Again, though, I don't use a custom hierarchy, so you might want to ask that question as a new post, just to get additional opinions.
    BTW, an iPod is not a reliable backup for your tracks. Too many situations can arise that would cause your iPod to need to be erased. I strongly recommend that you make backups, particularly of any tracks purchased from the iTunes Music Store or that would otherwise be difficult to replace, to CD, DVD, external hard drive, or other medium.

  • Macbook cannot detect D-Link DWM-156(A7) USB modem after upgrading to OS X Yosemite ver 10.10

    Hi
    My MacBook Pro 13" is unable to detect D-Link DWM-156(A7) USB modem once I open the D-Link Connection Manager app (to connect to the internet) even though the USB is plugged in.
    The MacBook is able to detect the USB at first, but once after I open the D-Link Connection Manger, it can no longer detect the USB Modem and a notification which says "No USB Modem Connected" pops up.
    This problem only surfaced after I upgraded the Macbook to OS X Yosemite ver 10.10. I tried to solve the problem by restarting the Mac but the same problem still arise.
    What do i do?
    Thanks in advance.
    Regards

    I figured it out!
    I had the same problem with the dongle sent to me by Telkom South Africa.
    Mine was D-Link Model: DWM-157. Here's how I fixed it.
    I basically flashed or updated the firmware on the dongle to the latest one I got from the D-Link website.
    1. You need access to a PC (Windows computer).
    2. Go to: http://www.dlink.com/uk/en/support/product/dwm-157-3g-hspa-plus-usb-adapter
    3. Scroll down and download firmware version 4.5.4.7
    4. Once download is complete, move over to your windows PC. Plug in the D-Link USB dongle.
    5. Run the firmware update on the Windows PC while the USB Dongle is plugged, Follow the prompts, it takes a little while, sometimes it seems like it is stuck but be patient. Once its done it will ask you to press any key to continue.
    6. After the install, pull out the dongle and plug it back in, sometimes the device installation prompt will appear. If so, rerun the device installation again. Wait for all the drivers to install. If not open d-link connection manager on your windows PC and test if it is able to make a connection to the internet. If the test was successful go to #7 below.
    7. Go to your Mac. Uninstall the current D-Link connection manager your have.
    8. Plug the USB Dongle back, the installation prompt will pop up again.
    9. Go through the installation steps and a prompt will pop up asking you to restart, restart your machine.
    10. Run D-Link connection manager and you can now get to the connection screen. Wait a while for network to be found.
    11. Click connect.
    12. Come back here and tell us if this worked for you. It certainly worked for me.
