Using VZAccess Manager v7 With Sierra Wireless SB555 Embedded Device

We have several Panasonic CF-29 Toughbooks with embedded Sierra Wireless SB555 devices. Up to now we were running VZAccess Manager v6.9 on these laptops without any issues.
For consistency sake we want to upgrade VZAccess Manager in these laptops to v7. From what I could determine VZAccess Manager 7 should work with the SB555 devices. This is where I came across an issue.
After installing VZAccess Manager v7 the Verizon Wireless - VZAccess dial-up networking connection was not created. Trying to connect failed: Connection not available.
I manually created the connection and I was able to connect. The problem is that whenever I use Detect Device VZAccess Manager deletes the connection and a new one is not created.
I have a temporary solution by creating a connection named BACKUP Verizon Wireless - VZAccess and then when needed just duplicate this backup connection and rename it properly. At least that is a solution in the lab.
This leads to 3 questions:
Is there a way to make VZAccess anager create the connection as it normally should?
When the automatic area coverage updating takes place, does that trigger a Detect Device? If it does not I guess I am safe to believe that the connection will not be deleted in the field.
Is there a way to reduce the time between the coverage area updates so that I can test this in the lab without having to wait days or weeks for it to happen on its own?
Thanks!

I would recommend uninstalling the current version of VZAM on the PC, and installing the VZAM software from www.vzam.net. I have listed the instructions below on navigating to the software.
Once on the VZAM home page, select supported devices on the red menu located on the left hand side of the screen
Scroll towards the bottom of the page for Laptops with Embedded Verizon Wireless WWAN Module
The 4th selection from the top is labeled “Panasonic Toughbook with global module.” Click on the version number that fits your Windows OS
Enter your wireless number
Before you download, check the two links below on whether you will need drivers for the WWAN device, or the Toughbook itself. I have listed the link below: 
http://panasonic.com/toughbook/support
http://www.vzam.net/UploadedFiles/Pan03_RevA_Driver.exe
If you are okay with the drivers, you can proceed to download the VZAM software by clicking the red download now button. Once selected, save the file to your desktop and install the software
***Download version 7.2.9 (2470a) for either Windows XP/Vista or Windows 7
***If step 1 is completed successfully (the drivers installed, the device was found, and the set up completed), the VZAM network connection will be automatically built.
2.      At the point that the automatic coverage update initiates, it has already detected the device. (If a device is not detected, you will not be able to activate it or update the coverage information.)
3.      To reduce the amount of time a coverage update can take, you can periodically perform a activation on the device. This can be done by selecting the “options” tab at the top of the VZAM menu, and select “activation”. This process will update the PRL (Preferred Roaming List) and coverage area.
I hope this information was helpful.

    Sorry, but no. Because the iPad does not have a cursor for you to use the mouse with.

  • Network Manager fails to connect with Sierra Wireless 3G/4G modem

    Hi,
    I have three Asus Laptops running with Arch (Asus N56VZ, Asus F3JC, Asus UL80VS). All laptops work with Cinnamon Desktop. Everything works fine except 3G Modem in Network Manager. I have two USB modems: Sierra Wireless AirCard 310U and Sierra Wireless AirCard 320U.
    Modems had worked fine in end of year 2012, when NetworkManager version was 0.9.6.4 and ModemManager 0.6.0.0. After update (NM >0.8.X.X, MM >0.7.X. - when the ModemManager.service appeared) until now, I can't connect to the internet on all Asus laptops. Since 2013 I have to use wvdial, because in wvdial modems works fine. It is Arch problem, because in Linux Mint 15 I can connect with NetworkManager.
    Sierra AirCard 310U - When I'm connecting to the internet, modem reboots itself.
    Sierra AirCard 320U - When I'm connecting to the internet, Network Manager can't obtain DHCP address.
    I would be grateful for any help.

  • Telstra Bigpond 4G Wireless Modem with Sierra Wireless Battery

    I have a Telstra Bigpond 4G Wireless Modem, which is run with a Sierra Wireless Lithium Ion batterry Model W-3, product no. 5200008.I got this from Telstra back in about Ausgust 2013 and have only recently noticed that my battery gets very hot, it is swollen and the edges are coming away from the from the unit. i spoke to my local telstra shop and they said I would have to contact Sierra to get a replacement. Is this what I have to do?And if so can someone lead me to Sierra Wireless website or email or number cause I've done some searching and can't find what i'm looking for.Would Telstra (bigpond) be able to help me with a replacement?CheersVicki

    I have read this post and must confess I have always found telstra to be fantastic suficiently so that we changed all our accounts across to telstra after a very long and loyal term with another provider.up untill we purchased the same wireless 4g unit as mentioned in this post we would have argued with anyone downing the tesltra service infact we have recomended amny many driends to our local Browns Plains Independant store (NOT THE TELSTRA SHOP STAFF At TTHE TELSTRA SHOP IN BROWNS PLAINS ARE THE RUDEST PEOPLE I HAVE EVER MET THEY CHASE CUSTOMERS AWAY WITH THEIR RUDENESS AND UNWILLINGNESS TO ASSITS INCLUDING THEIR MANAGER WHO I HAD THE MISFORTUNE TO DIRECT A COMPLAINT TO ABOUT THEIR CUSTOMER SERVICE, Telstra are lucy their is an independant resellar in the center)anyway the store the customer service on the phone all have been the best but I have the same problem battery over heating and swallowen luck I found it before it exploded it even popped the back off the unit.I went to my local independant unfortuanatly he didnt have a spare battery he susgested I try the Local Telestra Shop Or Battery world, not wanting to go near the local telstra shop I tried Battery World unfortuneatlly no luch they also advised i try the local Telstra Shop.How stupid am I what an un helpfull bunch of rude animals if I wanted to be treated like i had the plague I could have gone else where and should have they make you feel like you are some kind of criminal for having a problem or dareing to come in to their store how the generate any bussiness is beyond me, but like I fool I tried them no battery to replace my one no replacement units I could buy and no offer of a waranty repair. How ever I could go on another plan and get a different unit to the one I have I cant buy a replacement unit out right for cash because the sim card is locked to the unit but I can start another contract and just keep paying for my old one till its paid out.so I am looking for somewhere to buy a new battery , I have halved the services myself and my company have with telstra and out usuall Telstra accounts have dropped from about $2500 to $3000 dollars a month down to $700 per month while i wait for the contracts to end so the balance can be transfered to another service provider, and the plan with the $G wirless unit attached sits as it has for monthes now being paid for every month with zero useage.I had also tried the customer service line also with little luck and it appear that telstra and bigpond are to seperate idenities so dont ring the wrong one or you will be told in no uncertain terms what an idiot you are for not knowing they are seperate.so to all I say yes I am an Idiot for thinking that Telstra would give good service they are like fair weather friends will look after while you dont have a problem and are paying them without question but dont have a problem because they will dump you like a rat leaving a sinking ship i fanyone knows where i can buy a bettery i woeld be greateful otherise if i find a supply first i will post it herethank you to all for putting up with my rant but sooner all later we say enough is enough and I am not going to take it anymore.What happenned to good old customer service, I guess the electronic age did and face to face contact is no longer required so they can (like I am Now) hide behind their key boards and ignore you or treat you poorly,Please excuse my spelling mistakes I left my glasses in the car and am typing on blurry keys and screen. 

  • Problem using extension manager CS5 with command line

    Hi All,
    I had posted my question here : http://forums.adobe.com/message/4695419#4695419, but was advised to do so here as well..
    I have a requirement to get the path of all the installed Extension Managers on any Windows system for the purpose of installing an extension.. I thought, there would be no problem in getting the path from the registry. There was no problem in Win XP, but the same does not work for Win 7.. I googled, and found alternate ways to get the path.
    Here is the link : http://forums.adobe.com/thread/851359. I followed the instructions in this post, but failed to get this working for CS5 as mentioned in my previous thread... No problem for CS5.1 and CS6.. Why is that?
    I want to get this working for CS5, CS5.1, CS6... How can I get the path of all the Extension Manager versions installed on a Windows system?
    Please refer to the following screenshots to get a better understanding of my problem,
    I created a jsx file named "Result.jsx", which I saved in my D drive, with the following code,
    resultFile = new File("D:/result.log");
    resultFile.open("w");
    resultFile.write(BridgeTalk.__diagnostics__);
    resultFile.close();
    If I run this directly from ESTK CS5, there is no problem, and I get the result.log file. I tried to execute this script via command line as shown in the screenshot,
    On executing the above, I got the following error,
    What is going wrong?
    Please help!

    I am sorry for the poor documentation of Extension Manager which causes you so much trouble.
    1. You can use BridgeTalk API to ask specific version of Extension Manager to do something. There is sample in packaging_extension.pdf about this. You don't need to know the installation path of Extension Manager. One thing to note is that the value of bt.target is version specific, i.e. "exman-5.0", "exman-5.5" send this message to different version of Extension Manager, so you can change this value to install/enable/disable/remove extensions using different version of Extension Manager. More detailed documentation of BridgeTalk can be found by clicking "Help" menu then clicking "Javascript Tools Guide CS5" in "Adobe ExtendScript Toolkit CS5".
    2. Specific version of Extension Manager only manage extensions for corresponding version of product. You should use Extension Manager CS5 to install extensions for Photoshop CS5. The reason that the extension you installed for Photoshop CS5.1 using Extension Manager CS5.5 is displayed for Photoshop CS5 in Extension Manager CS5 is that two versions of Photoshop specified the same directory for Extension Manager to manage extensions. This is a defect and will cause some problems if multiple versions of Photoshop co-existed in one machine. But "to find  previous (CS5) extension manager and to enable it" should work for you, I guess you use command line to enable it and specify wrong product name (see #3) so that it doesn't work.
    3. When using command line, you should specify "product" attribute with the name displayed at the left panel of Extension Manager. So "Photoshop CS5 32" is correct. Remember to enclose it with double quote because of existence of space character.
    4. As above mentioned, use display name of Photoshop, and call proper version of Extension Manager by BridgeTalk.

  • HT5633 use of fn key with Apple Wireless Keyboard MC184LL/B

    Are the rules for using the fn key with the most recent
    Apple Wireless Keyboard MC184LL/B posted anywhere on Apple's site?  Thanks.

    Unfortunately i don't have a solution to your issue, but I thought I would mention the same issue with the new keyboard (MC184LL/B) and the iPad 2 running ios 4.3.5.  None of the function keys work as they should. 
    I recently received the older model (MC184LL/A) from FutureShop (Canada's sister to Best Buy) and everything works fine.  Perhaps you should seek out and buy the older model before they are phased out. 
    My only concern in saying this is I hope the update to ios 5 does not cause the older model keyboard to suddenly lose function key performance.  Similarly, I'm not sure the older model keyboard will work if you upgrade to Lion.
    I called Apple support about this issue and they found some info on the same iPad forums I have read, but they had no inside scoop on whether the issue was going to be addressed in further ios (or Mac OS) updates. 
    If you want to keep your new keyboard, you might just have to wait and see if the issue is resolved.   

  • Is VZAccess Manager compatible with Yosemite?

    Has anyone been able to get VZAccess Manager to work under Mac OS X 10.10 (Yosemite beta)?

    This is pathetic verizon. What's going to happen come December 25th when thousands of people get new macs for Christmas and find out your service won't work??? Can you say AT&T?! Spend less money on those stupid commercials and fix this issue. I now can't buy a new computer for my business because your lazy IT department can't figure out how to make the two play nice? Sorry if this sounds harsh, but this is truly unacceptable for such a large company. We are talking about an Apple product here. A very popular common sold all over the world product and it's incompatible with one of your core offerings.
    Fix this please.

  • Can I use the iPad 3 with older wireless keyboard

    I now have the IPad 3 and have the Apple wirless keyboard that I got for my IPad 1. I have not been able to connect it.

    No, as mentioned it is not useable as a true phone, and the carriers will not treat it as such,
    You can make voice over IP calls with it, just as you can with just about any internet connected device.  But no cell phone company is going to let you use a cell phone plan on a data-only device like an iPad.

  • Can iTunes from 2 different computer use the same library?  (from wireless data storage device)

    I purchased a wireless data storage device.  My iTunes content will be moved there and I'm planning on moving my wife's iTunes data to the wireless device.  Can both our iTunes share the same library?

    One Apple ID can be shared for store purchases. On the iPhone go to Settings>Store and put in the ID. Then all the songs purchased with that ID can be downloaded from the iTunes store on the phone.
    I hope that is what you were asking?

  • Using an Airport Extreme with a wireless router

    I use to have an original Airport Base station connected to a D-Link DSL504 ADSL Wired Router. All worked well.
    Then my basestation died so I upgraded my router to a Netgear DG834GT [108mps] ADSL wireless router. With this router I have never been able to get a full strength signal - even when the router is in the next room and my mac has been no more than twenty ft away.
    I am about to move house and where the router will be plugged in will be a floor below one of my computers so I am thinking my signal will not reach my mac [I will test it once I've moved before I rush out and buy anything.] I can turn my wireless signal off of my Netgear so I was wondering if I am able to plug in a new Airport Extreme and use that for the wireless signal? I will plug the computer near my router directly in and then from the router plug in the Airport Extreme.
    Does this seem a logical way or can a 'signal enhancer' from Netgear that would do the same thing? I think the usb port for my printer would be of some use for my laser printer.
    Thanks.
    Mark

    Yes, that will work. Just put the AirPort Extreme in 'Bridge Mode" and it will become a wireless node for your wired network.

  • Can I use my Ipad 3 with Verizon Wireless only on a month to month basis as needed?

    Verizon wants to bind me to an ongoing contract for my Ipad 3. I understood when I bought it from Apple.com 2 years ago that it could be on Verizon's data plan on an as needed monthly charge. It would not be an ongoing charge.  Then I would only pay a monthly charge of $10 for the months that I was signed into their data network. I could sign in and out of the network as I needed to.  I will only use the Ipad on Verizons network  2 to 3 weeks per year when I'm on vacation and away from my home wi-fi, (I have a different home provider for wi fi at home). I have only had it activated on my Verizon account one time a couple of months ago. I called a month ago to cancel my data service for the Ipad only, not my phones.  Since then, I have received emails say that they will continue to bill me. Is Verizon just trying to........? (Be Verizon).

    Re: Airplay. This is currently up to the developers to implement so it has nothing to do with Apple. Hulu have decided against it for legal reasons.
    IOS 5 will bring airplay mirroring with iPad 2 but will have to wait and see to test. It isn't out until the 12th.
    Airplay will work with the Macbook but only through iTunes

  • Using my airport extreme with another wireless device to hook up direct tv

    can i use my airport extreme and access my wireless router, so that i can hook up my directv box?

    Is your intent to provide Internet access to the DirectTV box via an Ethernet connection between the box and the AirPort Extreme Base Station? If so, it the other wireless router another AirPort or Time Capsule? If not, then this would not be possible unless you will be connecting the Extreme to the other router by Ethernet.

  • LOOK HERE: using an ipod shuffle with windows xp/gets unknown device error

    http://www.genesoc.com/node/405
    If this is similar to what's happening with your shuffle 2g ipod, I may have a weird solution. I spent a few nights troubleshooting this issue and searching many many sites and forums for solutions, all without success. Everytime I plugged the ipod in, XP gave one of the errors at the above URL. I did confirm on another pc that the shuffle was definitely working, because it updated and synched flawlessly. What I finally did to solve the issue was........... remove service pack 2. I know that's a bass ackward solution but it worked! I can now plug my shuffle in and it works everytime, perfectly. The only thing I can say for sure is it's something to do with usb 2.0 on my motherboard. It's a via board btw, with an apollo 333 chipset. Try it for yourself, and let's see if it works. Apple or some other company(you know who) needs to release a patch for this as it seems to be a very common problem.

  • VZAccess Manager for MiFi4510L?

    I'm caught between a rock and a hard place.  I can't get on My Verizon without them sending me a temp password in a text message.  I have a MiFi4510L, not a phone.  Customer Service says I need to use VZAccess Manager to be able to  read the text message.  I cannot find a version of VZAccess Manager that supports the 4510L.
    Can anybody help?
    Thanks.

    Hi John_Getzke, your MiFi device is activated with a wireless number to use our network just like a wireless phone. You wouldn't have known that unless you have a order receipt or bill.  You can find the wireless number assigned by doing the following:

  • Sierra Wireless EM7345 ThinkPad 8 and 10 general issues

    This was posted as a reply to german forum but it was deleted Symptoms (mobile connection is connected)
     1. mobile connection randomly disconnects. It is possible to reconnect again. 2. when resume from Connected standby mode the mobile connection appears to be connected but it is dead. It is not possible to disconnect nor turn off the mobile connection, it is stuck. Windows restart is required to resolve it. 3. when resume from Connected standby mode the EM7345 composite device disappears at all from Device Manager and new unknown device '1 CDC' appears. Windows restart is required to resolve it. Note: Issues 2 and 3 occurs when running on battery only. I don't have any occurence when the tablet was plugged in AC, turned off (into Connected standby mode) and on, yet. I have already tried to reinstall the 1.6.10513.4153 driver, no luck. I have also tried to disable 'USB selective suspend' feature in driver settings and switch off GNSS device (because it has Sierra Wireless driver), no change. I have latest BIOS 1.24 (ThinkPad 8, 64 bit). It is hard to reproduce the case 3 but I have almost reliable steps: 1. uninstall current driver (even it is the latest version)2. restart3. install current 1.6.10513.4153 driver, select Custom Setup, make sure the 'WWAN Logging Tool' is selected, finish the installation4. restart 5. establish mobile connection6. go to Start menu, Intel group, start 'M.2 WWAN Logging Tool'7. press Start Trace button8. turn off the tablet (while the tracing is running) by power button, wait for a minute 9. turn on the tablet(repeat steps 8 and 9 multiple times, in case you can not reproduce it at the first time) EM7345 device disappears with typical unknown 1 CDC device. Yes, it is not a standard operation but it is easily reproducible with the same result. Similar issue is reported in other forum posts for ThinkPad 8 and 10

     Old firmware 1.1 that can not be updated to 1.2, read this thread http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T540p-Sierra-WWAN-EM7345-reliability/m-p/1839271#M106663 The 1.2 firmware might help to resolve the issue (although this post states it actually did not help). Technical details When the USB composite device (EM7345 = WWAN + GNSS) disappears it incorrectly identifies itself as VID = 1519, PID = F000 so Windows can not find proper driver for the device and displays it with (?) icon. If you remove the '1 CDC' device from Device Manager and perform 'Scan for hardware changes' this time it is correctly identified as VID = 1199, PID = A001 and installed (these tasks can be automated using devcon.exe command-line tool, so the fix wouldn't require OS restart everytime it occurs. It is still hack, not a solution). It looks like a firmware bug because the USB composite device and WWAN MBIM device uses Microsoft generic driver. Summary Given the price tag of ThinkPad 8 and 10 tablets, Lenovo should fix that because this is basic functionality failure. Disappearing WWAN device that needs full restart is really serious issue. And again, please diagnose and resolve the issue (hint , hint) instead of "try to reinstall this, try to reinstall that, replace this, replace that" advices. It leads to nowhere because the driver/firmware is buggy as it was in the past with Ericsson device. (copy of the post is stored)
