T420 / UMTS WWAN circumstances

hello community,
after trying everything i found referring the problems with wwan - umts connection with my t420 / 4236 / NFG
i´m here asking for your kind help!!
as far as i could fix it now, is the umts works when i start the laptop and I dont connect to any w-lan or lan network before connection with umts - using lenovo access connections
it is still not working when:
+ access connections is / was connected to any other profile
+ the laptop wakes up from sleep / energy save or hypernation mode - "no service providers available"
IT IS SO ANNOYING!
i have bios 1.37, everything updated with lenovo update, ac 5, and the thing is it was working perfekt the first 2 days i had my laptop before i did the updates....
anyway, rapid boot is still not available in my bios, the booting time of the notebook is way too long, specially if i have to restart anytime it turns sleep mode or i connect to any w-lan - and want to go back to umts................
if you need any info - let me know, would appreciate some help on this issue!

mad_t420,
Try downgrading the Lenovo AC to previous version.

  • T420 WIFI & WWAN conflict

    I have a couple T420 model Thinkpads with the Qualcomm Gobi 3000 chips installed and being used on the Verizon network.  The problem is that when the user connects to the Gobi, they get disconnected after a specific timeframe, be it 10 or 20 minutes.  Thinking it was a Verizon issue, they helped troubleshoot the issue and it looks like the Gobi chip disconnects when the WIFI card in the laptop starts polling for nearby WIFI networks.  I had one of the reps manually turn off the WIFI radio when he used the Verizon connection though the FN+F5 shortcut, but he called back later to say that the radio turned itself back on after 10 minutes to start polling nearby networks again and knocked him off.  Is there a setting I'm missing somewhere or an update I need to apply so I can get the WIFI radio to stop polling at regular intervals when another connection is being used?

    That also turns of the WWAN card, so it not going to do anything useful for this problem.

  • T530 UMTS/WWAN: einige SIM-Karten funktionieren nicht und Win 8.1

    Hallo,
    in meinem T530 ist ein Ericsson H5321gw UMTS-Modem verbaut.
    Bislang habe ich verschiedene Vodafone-SIM-Karten im UMTS-Modem verwendet und mit dem Windows 8.1-Netzwerk eine Verbindung aufgebaut. Windows hat sogar von sich aus meistens die richtigen APN-Einstellungen gefunden.
    Soweit so prima!
    Nun habe ich mir auch SIM-Karten von Congstar und PennyMobil, beide T-Mobile-Netz, zugelegt.
    Bei beiden Karten meldet Windows, dass eine Netzwerkverbindung nicht möglich sei.
    Das Prozedere ist folgendes:
    1. Einstecken der SIM
    2. Einschalten Mobiles Breitband
    3. Auf Verbinden klicken
    4. Es wird die PIN abgefragt.
    5. Nach Eingabe der PIN erscheint für 1...2 s der Netzname (Congstar oder Penny)
    6. Danach verschwindet der Name und es folgt die Meldung: "Verbindung nicht möglich"
    Wenn ich auf Wiederholen klicke, kann ich manuell die Zugangsdaten eingeben.
    Diese funktionieren jedoch genau so wenig wie das von Windows vorgeschlagene T-Mobile-Profil.
    Beide SIM-Karten funktionieren einwandfrei in einem Huawei USB-Surfstick.
    Eine Tchibo (O2)-SIM funktioniert ebenfalls bestens im UMTS-Modem.
    Access-Connections habe ich bisher nicht installiert, weil ich mit der einfachen Windows-Funktion bislang wunderbar auskam.
    Mit diversen NetShell Befehlen habe ich eine Analyse versucht.
    Der Heimanbietername und die ID werden korrekt erkannt.
    Sonst liegt der einzige wesentliche Unterschied zwischen den funktionierenden und den nicht funktionierenden SIM-Karten darin, dass bei congstar und Penny keine Profile vorhanden sind und bei den verfügbaren Netzen das Netz mit dem Status "registriert" und der ID 26201 (T-Mobile) spannenderweise keinen Namen hat.
    Ob es so ist, dass es keinen Namen trägt, weil keine Profile da sind oder keine Profile verfügbar sind, weil der Name leer ist, entzieht sich derzeit meiner Kenntnis.
    Der Name erscheint ja kurz nach Eingabe der PIN und verschwindet gleich wieder.
    Irgend jemand eine Idee in dieser verwirrenden Angelegenheit?

    So, habe das Problem nun selbst gelöst. Laut dieser Quellle gibt es ekeine offiziellen Treiber von Micrososft für Windows 8 und 8.1 aber die Win 7 Treiber sollen funktionieren.
    Habe also diese Treiber heruntergeladen und die .exe ausgeführt. Angeblich gab es das entsprechende Verzeichnis bei mir schon. Habe einfach alle Daten überschrieben und die Installation gestartet. Hier sagte ich dann "Programm ändern" und hackte einfach alles an, was anzuhacken war.
    Danach tauchte im Gerätemanager nun ein Smartcard-Leser auf und zwar der F5521gw Mobile Broadband USIM Port. Unter "Netzwerke" habe ich nun auch "mobiles Breitband" stehen und kann meine SIM aktivieren.

  • T420 WWAN+Finge​r Print Reader not in device manager?!?

    Hi,
    Im new to lenevo and this is my first one..its a Lenevo T420 4236P3G. I have been advised by Lenevo support that my machine is WWAN compatible and has a Ericisson 3G card built it...I also know it has a fingerprint reader which is clearly on the machine.
    Problems I have 
    1) The sim card slot behind the battery seems really odd!? I KNOW if I put my sim in there it will just be lost forever. There seems to be no "click" in and out mechanism..Iv tried with a dummy sim with a string attatched and it defo does not have a click to it...If I put a normal sim in it would just be stuck forever..
    2) I have a fingerprint reader and WWAN built in..BUT both of them do not appear in the device manager?! There are no devices which are unreconized and everything is accounted for so its defo not a driver problem...they just dont physically show!!
    Iv already updated the BIOS, used lenevo update, tried both Legacy and UEFI bios options in the bios...
    Only thing that it may be is my machine has a clean install of Windows 7 pro..Support have said they are sending me out copies of the original recover disks but I just dont see this working?!?I mean if they have disappeared and are not even picked up by the laptop in device manager then how will they run through a different install???
    Tried using google but been no help..hope someone here can give me a hand
    Thanks in advance

  • T420s WWan Compatibil​ity - H5321gw or not ?

    Hi there,
    I was looking through the parts lists for my T420s (4174-P4G) and noticed here :
    http://shop.lenovo.com/SEUILibrary/controller/e/gb​web/LenovoPortal/en_GB/catalog.workflow:show-categ​...
    http://support.lenovo.com/en_US/product-and-parts/​detail.page?&DocID=PD024213
    That the H5321gw clearly comes up as a part for the T420s 
    Is this a mistake or is this card in the whitelist in our BIOS ? As this card actually has proper Windows 8 drivers and I have one laying around, wondering if I should try putting it in or not.

    Hey there DangerMouse,
    I'm uncertain on where you are seeing support for the T420s on the links you've provided:

    Looking in the parts manual I am able to find the following:
    Ericsson Mobile Broadband Module F5521gw, with FRU Number: 60Y3279
    The whitelist will require that not only the card be on there, but it is a Lenovo FRU. You are able to tell this best by ensuring the FRU number is listed physically on the card. I believe the card you are referencing can go into the T430s. Now of course, you can still give it a go and see if it'll work. If does not you'll get something like an 1803 error.(Not 100% on the error code.) But it will tell you to remove it.

  • UMTS / GSM unstable

    The UMTS / GSM module seems to be unstable. Means
    - CPU load 30 - 50% for AcSvc.exe
    - connection is lost latest after 60min
    - PIN code is often asked, even if i request to save it
    I am using WinXP (all Updates installed) and Thinkvantage Access connections v5.30
    Any idea, what is wrong?

    Hey there !
    We have an ongoing topic for this located here :

    It is unlikely to be software related, more due to the firmware inside the actual WWAN card !

  • Fitting an SSD to the T420, and moving Windows to it WITHOUT a reinstall

    Hi there,
    I'd seen some threads around about the T420's suitability for an SSD in the WWAN slot. Well I've just received my T420, and had ordered one of the Intel 80GB mSATA SSDs. I spent this evening moving the Windows install from the 500GB hard drive to the SSD, and didn't need to reinstall. I don't know why Lenovo don't offer the SSD as an option!
    So I bought the 80GB Intel mSATA SSD from Ingram Micro; you can just fit it into the wireless WAN (i.e. 3G slot) in the T420 - took about 5 minutes, and you just have to tuck the aerial leads out of the way when you put the bottom back on. The BIOS detects the SSD without a problem.
    M'colleague Pete suggested the trick to avoid a reinstall of Windows 7. In brief, we shrank the HDD's Windows partition down to 50GB, created a mirror of it on the SSD, then rebooted off the SSD and removed the mirror.
    In some detail:
    1) make a recovery disc before you start (I didn't but I know this stuff!);
    2) defragment your C drive (right click under My Computer, go to Properties->Tools and choose defragment). Took about 45 minutes to finish on mine;
    3) go to Computer Management -> Storage -> Disc Management;
    4) right-click both the SSD, and the internal hard drive, and convert both of them to Dynamic Disks
    5) right-click the larger of the two windows partitions on your hard disc, and shrink them to the size of your SSD (i.e. 74GB if you want to use the whole SSD for Windows) - wait for that to complete;
    6) create a mirror of the first two partitions on the hard drive, mirroring them to the SSD (i.e. right-click each partition, click Add Mirror, and choose Disk 1 as the destination);
    7) wait for the mirrors to complete (i.e. the Rebuilding... message will go away).
    8) start an administrator-mode command prompt (go to Start, type "command" and click the "Command Prompt" option while holding ctlr+shift);
    9) type "bcdedit /enum" and note the long number associated with the SECOND boot option. Then type "bcdedit /default {xxx}" where xxx is the number. For good measure type "bcdedit /timeout 2" to make sure you see the menu and can fix a mistake manually;
    10) reboot the system - before it comes back you'll see the windows boot loader menu - choose the second option (should be the default), which is to boot off your SSD
    11) when windows comes back up, you can go back to the Disk Manager and choose "Remove mirror" for disk 0, and you can reclaim the space. Hooray!
    That is about the minimum that you need to do to move the partition and get it to boot.
    I wasn't sure how to tell windows to install a bootloader on the SSD, and completely disengage the hard drive from the boot process, but I'm sure someone will fill me in. 
    NB I've not tested the above sequence PRECISELY, as I had some further fiddling to get my Linux installation to work, which isn't relevant to the above trick. I'd be interested to know if it works for someone else - as I said, please make sure you have your recovery DVDs and backups handy just in case.

    You could have used Intel's Clone tools. My experience is that you are better off following the prescribed method of using the rescue disks to do a reinstall. The system seems to boot faster that way.
    When asking for help, post your question in the forum. Remember to include your system type, model number and OS. Do not post your serial number.

  • No UMTS after upgrade

    Hi,
    after I updated the last patch on testing (the one delivers Gnome 3.8) I've got problems with my UMTS Stick (Huawei Vodafone). Before this upgrade everything worked well, I'm searching since some hours for a solution, but may be you could help me.

  • [SOLVED]ModemManager 0.7 breaks support for Ericsson F3607gw WWAN card

    Hello,
    apparently the ModemManager v 0.7.990 currently in the repos no longer supports my WWAN card, a Dell 5540 Mobile Broadband (which is just a rebranded Ericsson F3607gw).
    ModemManager 0.6, which is the version used in Fedora 18, works just fine with the card and connections can be made.

    However, I cannot downgrade to MM 0.6 as Gnome 3.8 and NetworkManager require >=0.7.
    Has anyone encountered this problem before and has a fix/solution? Or should I file a bug in the Arch tracker? I got Bluetooth PANs to work with a patched bluez from this board, as the upstream version is behind the one used by fedora (4.101-1 vs. 4.101-4). WWAN is the only thing that doesn't work with my new Arch setup.
    Thanks in advance, any help would be much appreciated.

    I slightly modified modemmanager-git in the AUR and added some dependencies, the git version now works for me.

  • Getting my T420s to boot faster: Your collective wisdom

    I have a brand spanking new 1 week old T420s and I’m very happy with it so far.
    I have been reading about Lenovo’s 7 second  rapidboot extreme, and I get that it will only work on preloaded machines with the special BIOS etc. Mine is a work machine, so it’s has our standard company Win 7 image as well as other software. I am interested to make mine boot as fast as possible though, within the limitations I have. So far it boots in around 40s - 44s, which seems far slower than other T420s. We use disk encryption, so I measure it from when I’ve entered the encryption software password (and Win starts booting from that point), to the desktop when the cursor stops spinning. To the actual desktop itself is around 35s - 40s.
    My machine is: T420s, i5-2540M, 8Gb RAM, Intel 160Gb SSD, Win7 64 bit. Some of the software that I need to have: Sophos disk encryption, Cisco AnyConnect VPN client, Iron Mountain Connected Backup, Office 2010 and Symantec anti virus.
    According to this article, this is what it takes for a 7s boot:
    http://www.lenovoblogs.com/lenovofiles/2011/01/26/lenovo-enhanced-experience-2-10-second-pc-boot/
    1. Custom UEFI firmware from Phoenix (even if I could get it, UEFI doesn’t currently work with my disk encryption software)
    2. Native UEFI mode 64-bit install of Windows 7 (GPT format) (again, not an option)
    3. Intel 160GB SSD (M-class) (not sure if I have M-class, but I have an Intel 160Gb SSD)
    4. Driver and service optimizations and tuning (Something I can do!)
    5. One part secret sauce (??!?!)
    So clearly all I can do is play with the loading of startup and services. Please note I’m not an IT person, but I’m comfortable tinkering with settings, within reason as I can’t have the machine crash. I have downloaded all the latest drivers, and installed the RapidBoot software.
    Below is a snapshot from services.msc showing what services that are still automatically starting up. Honestly I don't know what some of the services are so haven't been willing to play with them in case it goes pear shaped. I would like to delay the VPN, iron mountain backup, WWAN and antivirus, but not sure where to do that, as i couldn't do it here.
    So do any of you guys have suggestions on what I can do to make it boot faster?
    Thanks for any assistance you can provide!!!!!

    Soluto is one such free software that you can use to check the bootup speed and what each element is conributing to the time. There are 3 divided areas that you can tweak (no way / up to you / no brainer). Each service you can read what is the function and whether you can turn off or delay..
    Thanks Ideasmiths. I did try Soluto, but then i uninstalled in. I noticed the software sends back through to themselves all the startup info and stats of your machine. I didn't have time to read through and understand the implications of it all, so i wasn't comfortable with it.
    I did notice Soluto could delay loading stuff like the VPN etc, which made a difference to the boot up time. But I also figured if the SW could do it, there must be a way i can configure it myself to do the same thing?
    And I guess in a way thats what i'm asking - how can i delay the startup of the non essential SW that can't be set to Automatic (Delayed). Agree, I'm not after all out boot speed at the expense of system stability. And there is SW i still need, but I don't need them at startup.
    ColonetONeill, thats exactly what I want to do - delay the startup of the antivirus, the VPN, and the backup software. But I'm not sure how to do that. I completely disabled the VPN, and it shaved 3s off the boot time.
    Thanks for the suggestion of eBoostr. I'll have a look.

  • Drivers for T420, T420S, T430S and other musings...

    First time poster here!  Thanks!  I like the Thinkpad series, but I do have some questions.
    Drivers for T420, T420S, T430S...The drivers page for these models is confusing. We overwrite the image that comes factory for our thinkpads.  So when I load Windows 7 there's still obviously a handfull of drivers you still need as well as maybe  some of the options from Lenovo that "improves" functionality. 
    The confusion for me is around the network cards, wireless...LAN.  The problem we have currently is that the previous image we made/deployed for our laptops contained a mix of conflicting drivers for wireless.  I think I have it fixed on the new image but I want to make absolutely sure we're cool.  We have a mix of both LAN, wireless LAN, and wireless WAN users that we support.  At any rate, what might help is a list of all the specific drivers I need based on my full model number.  Any takers out there for this one?  I doubt this sort of list exists on their website.  When I visit the Lenovo drivers page and search for and click on the link for my full model, i.e. T420s-xxxx, I get a multitude of networking driver options! 
    Also just curious, what are some of the non essential software from lenovo that you guys like on your systems?  I hesitate to download it all but I think the Thinkconnections piece works very well for wireless to LAN switching...

    I understand what you're saying.  But when i type in the T420S-4171, there are mutliple network drivers.  Are you telling me from top to bottom you download and install every single driver?
    Sorry i wasn't clear, i meant the type, e.g. for my T420s its 4174-bz7. This brings up the configuration of your machine and a list of drivers for your specific hardware. You then choose based on your hardware - for some things e.g. WWAN there might be multiple hardware so you choose yours. You can check device manager if you are unsure.
    The Type is on the sticker at the bottom of the laptop. See here for locating it: http://support.lenovo.com/en_US/basic.page?DocID=H​F002641

  • Dell 5540 (Ericsson F3607gw WWAN) problem - sim-missing

    Hello,
    I'd like to use internal WWAN modem in my laptop (Dell E5440). Originally there was Sierra Wireless AirPrime (Dell 5570) which was not working at all on stock kernel. After some googling and tweaking kernel modules I got it to the point, where it was partially discovered, but ModemManager said "sim-missing". I left it in this state because I found nobody who ever got it working on Linux... but yesterday I got a chance to swap it with Dell 5540 modem. So i did.
    And... it is not working ;-)
    There is of course big step forward - as the modem is properly detected and so on, but... "sim-missing" keep appearing.
    There is no entry of "WWAN" in NetworkManager.
    SIM card is of course present. When I put this SIM card into Huaweii USB modem - it works - it shows in NetworkManager, accepts PIN and allows to connect to the network.
    I have read https://wiki.archlinux.org/index.php/USB_3G_Modem and did as it was written.
    I've found this thread https://bbs.archlinux.org/viewtopic.php?id=162295, but it's about version 0.7 of ModemManager and now we have version 1.2 so it is obsolete.
    Does anybody has an idea what is wrong? What can I check?

  • T420s ultrabay or external HDD

    Hello everyone!
    I'm thinking of increasing my T420s HDD capacity since 128GB SSD is not enough for me anymore. I have two options:
    1) to buy an external HDD with usb 3.0 (e.g. WD my passport ultra)
    2) to buy a ultrabay chassis and 2,5" HDD inside
    The question is: which solution will be faster in terms of reading/writing files and managing backups?
    My model is T420s 4171-7FU.
    Thanks in advance for any advice
    Best regards,
    Matt
    T420s type 4171-7FU

    Hi,
    If you haven't installed a WWAN card in the WWAN/mSATA slot, an mSATA SSD might be a 3rd option.
    My own preference is a 256GB mSATA SSD + a large-ish HDD for data in the main drive bay.
    I think the "s" has the slots to do that...

  • What SSD Drives are supported on the T420

    I am getting a T420 as my new Corporate laptop.   I want to buy an SSD drive to replace the internal hard drive.   I found the newest bios/firmware and looked at the Readme file.  It lists the latest drives and model numbers but not any of the previous models?   How do I get a complete list of all SSD drives/models supported on the T420?  The laptop is going to be imaged with Win7 if that matters.  
    Any info is appreciated.  
    Solved!
    Go to Solution.

    Hello and welcome,
    Any list of drives you find in the README will be a list of drives supplied by Lenovo, not a generic list of drives that would work.
    From the ltwbook ( ThinkPad Notebooks; 2005 to present (withdrawn models) ):
    Some: Solid State Drive (SSD) / SATA 3.0Gb/s, 2.5" wide, 7mm high
    Some: Hard Disk Drive / SATA 3.0Gb/s, 2.5" wide, 9.5mm high, Active Protection System™
    So if you're replacing a hard drive, any 2.5" 9.5mm (or 7mm with adapter) SSD should fit.
    Another option you might consider is an mSATA SSD. [edit] If the WWAN/mSATA slot is empty - no WWAN card installed.  I use a 256GB Crucial m4 in my T420.  The HDD is still installed as a data drive and spins down when idle.  It's a nice quiet combo with plenty of storage.  I also keep a backup of the SSD on the HDD.

  • X1C WWAN not supported in Canada anymore?

    As I get ready to pull the trigger on an X1C, I find that the WWAN is no longer included and isn't available as an option in the Canadian store.  
    It used to be, what happened?
    Also, I'm still waiting for an i7 w/8GB RAM option which also isn't surfacing.

    s0dhi,
    X1C supports mini PCI-e Half (!) Size wwan card. Presently it's Ericsson H5321gw card only (from officially supported wireless cards list). It operates in GPRS/WCDMA/HSPA/HSPA+ networks so the answer of your question depends of your carrier network type - is it UMTS or CDMA/EV-DO.
    Or you can find another wwan card in half size formfactor with CDMA/EV-DO network support but have to think about wireless card compatibility list.
