I bought two brand new X270's WWAN upgradable and bought EM7455 cards separately. I installed the cards as directed. When I booted the laptop the first time after installation, a warning message saying something to the effect of "unknown network hardware EM7455." Windows didn't detect the newly installed card. So I did a CMOS reset (removed the extra battery, disabled the built-in battery on the BIOS and pressed the CMOS reset button to the left of the battery bay). After the CMOS reset, Windows recoginized a new hardware by the name of "Sierra Wireless EM7455 Qualcomm" but couldn't install the driver (see the attached screenshot). I did install Lenovo's EM7455 driver (total file size 191MB) and didn't work. I turned to Sierra and found a generic USB Build 4581 driver and it didn't work. When I restarted Windows, the newly found hardware was gone. I did a CMOS reset again and it came back up on the device manager list.  So I turned to Windows update. It found a driver update by the name of Sierra Incorporated - Ports dated 10/20/2016. It tried to install it but it failed. However, the device's name was changed to Qualcomm COM Port (3) and it was still not installed properly. I went to the device's properties and changed the port to 8. It recognized the full name of the card but GPRS connecitons on Windows didn't show up. I restarted Windows, and the device was gone again! I checked the BIOS permissions and I tried different scenarios (disabled WWAN, e... Read more

I bought a new P71 portable workstation with this WWAN card already installed and I've got a SIM card from Bell Mobility in Canada. The card seems to be activated but there is a very limited traffic. I ran the diagnostic and it says that there is a second PIN that need to be provided. I followed the instruction from my provider to unlock the SIM card, but the diagnostic is the same. I donwloaded the suggested driver from the Lenovo support page but the installer indicate that there is nothing to update. I'm looking for a new direction to look for to solve ths problem. Thanks Dominic

I just finished retrofitting WWAN antennae to my X1 Yoga OLED 2nd generation (what a job!). On eBay I scored two Lenovo EM7455 M.2 wwan cards:01AX746WIRELESS WAN ADAPTERS  FRU Sierra EM7455 WWAN Module Rel16. and:01AX748WIRELESS WAN ADAPTERS  FRU Sierra EM7455 WWAN Module Raven2 I know both of these are compatible with my x1 yoga 2nd generation. But is one better / newer than the other?  Related question: the older Lenovo versions of the the em7455 do not work in the newer machines (x470 / x1 yoga 2nd). But is the converse true, that the newer em7455 revisions will not work in the older machines (x1 yoga 1st Gen for instance)? If someone confirms the newer cards work in the older machines I may put one of these two in my other x1 yoga (1st Gen). Thanks any info.

I have an X1 Yoga 20FQ with Windows 10 Enterprise 64-bit and a Sierra Wireless EM7455 WAN card that came with the unit from Lenovo and an AT&T micro SIM card (also in the unit when it came from Lenovo). I also have the latest Lenovo software for the Sierra Wireless card (v. 7.47.4743.0105) from the Lenovo web site. The WAN card will connect to HPSA on AT&T (using the "default APN" and "broadband" in the Win 10 settings) but it will not connect to AT&T LTE. The AT&T web site at https://www.att.com/esupport/article.html#!/wireless/KM1218316 says to use NXTGENPHONE as the APN, but when I input that as the APN the card does not see it at all. I know that NXTGENPHONE is the LTE APN because that is the APN that my cell phone uses for its LTE data connection. AT&T tech support told me I the Windows 10 and NXTGENPHONE APN settings are correct and the AT&T diagnostics show I an LTE connection is available to me.I realize that there can be sources for this problem (Win 10 or AT&T) but I thought I would ask here to see whether anyone has experienced the problem or has a solution.Thanks.

Hi Guys,First off, thank you for this very wonderful resource. Now, I will try to make this short and simple and hope someone can help me out.I currently am using a T430s which I ordered a Sierra MC7550 (GOBI 4000) mini PCI card for to have internet (4G) on the go via verizon.I followed all instructions and installed the card without any issue. I booted the notebook and notice a little popup in my tool tray that said the hardware was not successfully installed. I then tried using System update to install the driver which seemed to have installed everything successfully. I opened my network connections and still didn't see the new device so I decided to open up device manager and saw that something was wrong.The MC7750 was listed under "Other devices" instead of "Networking" and had the yellow exclamation point next to it.Currently the exact error is as follows:The drivers for this device are not installed. (Code 28)There is no driver selected for the device information set or element.To find a driver for this device, click Update Driver.I tried manually downloading/installing the driver from Lenovo's site, using System update, manually pointing to the downloaded driver's path and nothing seems to fix it.I am hoping someone could help me here. I'm not sure if this is Lenovo branded or not however I'm not getting any BIOS errors upon boot. I'm running the latest BIOS and Windows 7 Pro 64bit.There's not much information on this card via the net and I assume this is because of it... Read more

UPDATE: After hours and hours of research and contacting lenovo support via phone to no avail I decided to install the MC770 driver (same device, but for AT&T) and downloaded the installation file from AT&T and VIOLA! It installed and I was able to see it in my device manager under Network adapters.I'm not sure if its fully working yet because I had no idea I needed a sim card.. I thought i could just call up verizon with my IEMI number and have it activated... either way I consider this one step closer and it leads me to believe that something is up with the driver download from LENOVO. Also, could I buy a prepaid Verizon sim card and use it in here or? IF this works fully and flawlessy, I hope this helps someone to prevent them from going through what I went through. Hopefully Lenovo updates their drivers.*** I ask that you guys still kindly reply to let me know if I am missing something here. Thanks.

In fact if I suspend and restore the notebook, the trascend disk appears connected again and I can use it as usual... but just for few minutes. I tried:- Configure the power manager to never suspend disks. Did not help.- Upgrade BIOS firmware. Did not help.- Using Lenovo Storage Device Firmware to update firmware's disk: It looks like has no support with Trascend SSDs. Now i really don't know what to do.

I am installing an EM7455 WWAN card in my P70. The User Guide states that the SIM used by the system is a Micro-card. When I called Verizon Wireless to obtain a 4G-LTE card, they could not find the P70 in their database. However, they said they knew the size and shipped me a SIM card. Unfortunately, it was the incorrect SIM-card size (apparently there are multiple) so I have to obtain the correct card from a Verizon store when the WWAN arrives from China. The model number of the card needs to end in 3FF-A. It would have been really convenient if the Verizon SIM card was orderable on the Lenovo website at the same time as I ordered the EM7455 from the Accessories storefront.

Hi!I have a Thinkpad X220 with the BIOS whitelist removed. I just installed a Sierra Wireless MC7304. After installing the drivers from TechShip, the card is recognized as well as the inserted SIM card. However, it says "turned off" and I can't get it to turn on.Now, I have one more detail to share. The built-in SIM card holder on my X220 got broken previously due to a NANO sim adapter trashing the connectors. With a SIM in this slot, it doesn't get recognized. To get around this problem, I have installed a SIM Card adapter for mini PCI Express modules (https://techship.com/products/sim-card-adapter-for-mini-pci-express-modules/). With this fitted to the WWAN card, the SIM gets recognized. However, I see two Cellular connections (see attached screenshot). In device manager, I also have 3 Sierra Wireless network adapters.I assume I should disable some of these adapters to get this working by looking at hardware IDs. Any idea how to identify and diable the adapter coming from the broken sim card slot?

I recently installed an EM7455 LTE modem (FRU 00JT542) and antenna kit (FRU 01AW958) in my X1 Yoga running Windows 10 Pro.Drivers installed fine and I have nothing unidentified in Device Manager, and "Cellular" exists in the networking panel (when you click on the network icon in the taskbar).However, none of my SIM cards are being detected by the system. I've tried T-Mobile and Verizon SIM cards (both verified working in other devices) to no avail -- Windows keeps telling me to insert a SIM.I spent all afternoon on the phone with half a dozen Lenovo support reps (and have a ticket open with them) but we haven't made any headway yet. Here are some things we tried:Different Windows 10 installations (the original image on the supplied SSD vs. the one I created and have been using on my 950 Pro): no effectThe Windows 7 Mobile Broadband Activation tool: errorVarious Gobi 5000 Drivers: no effectUpdating UEFI: no effectWindows Troubleshooting: uselessI'm beginning to think it may be a hardware issue with the SIM slot but the reps haven't been willing to admit as much. In addition, I only have the depot warranty which I've heard atrocious things about, so I'd like to avoid that. I was also informed that they don't allow self-replacement of system boards so worst case I'll have to shell out for an onsite warranty.I'll take any suggestions -- even if they're shots in the dark!

Not sure if this is a problem, more just a question... I installed a brand new Sierra EM7455 WWAN module a few days ago in my X260--got it direct from Lenovo. Getting it working was a little convoluted (had to reset BIOS) but it connects just fine to AT&T. The question or concern I have is when ever I restart the computer, I get a pop-up in the lower right that says "Configuring mobile broadband device...Do not shut down or restart Windows." It takes about 1-2 minutes, says "success" then everything is fine. The "problem" is that this happening every time I reboot. Has anyone seen this or know what's wrong? I've attached a screenshot of the message. I installed the official Lenovo drivers for the EM7455. I tried uninstalling the Sierra package and the message goes away--but so does the WWAN module... I re-installed the driver package and now the message is back. I had an X250 with the previous gen Sierra WWAN module and it was generally trouble free, no strange issues like this. Thanks

A:Sierra Wireless EM7455 COM ports are Locked... Lenovo Why do you do something like that?

Hello and welcomeThat's not a Lenovo deal to lock the ports, more clearly, to choose appropriate default USB composition. MS and Sierra do that. To change default USB composition change Sierra wwan card drivers installation configuration and reinstall them. Edit the configuration.ini file within the drivers package:- [Default Values] section- USBCOMP=x parameter (choose 8 as you want).

Hi! I have a T430 2347CTO. The notebook has an Intel Wireless LAN (11abgn, 11bgn, 11ac) adapter installed. 1. The WLAN adapter is causing problems and I'd like to replace it, but I'm not sure what I should install instead. Any tips? 2. I'd like to install a WWAN adapter, but I'm not sure if my model has the required antenna installed. Does anybody know if it has?

A:Thinkpad T430 - replace WLAN card and add WWAN card

I confirmed that this WLAN card will work: https://www.ebay.com/itm/Hot-Intel-Dual-Band-Wireless-AC-wifi-Card-for-Lenovo-Thinkpad-X230-T430-60Y...
 
And I also confirmed this WWAN card will work: https://www.ebay.com/itm/Gobi3000-3G-WWAN-Card-60Y3257-for-Thinkpad-X220-X230-T420-T430-W520-W530/22...
 
The WLAN card is N wireless; and the WWAN card is 3G.  The ones I linked to are shipping from the US and the best price I could find.  
 
Hope that helps!

Hi I resently got a Thinkpad x1 yoga gen 2Type 20JE-S1C600S/N R9-0NGFRQ 17/05 As far as I know there should be a Sierra Wireless EM7455 modem in the machine, but i can't get windows to detect it. I doesn't show up in device manager, or in the network setting of windows. It is running Windows 10 Home. 64bit. In bios I can enable or disable WWAN (under security > IO ..), not sure if that means there is a modem, or just a setting thats always there in the bios.There is a slot in the back of the machine for a SIM card, but not sure if that means there is a moden in the machine, or the slot is always there.  I Tried reinstalling the machine, but didn't help.I've made sure there is no pending updates for the machine.   1. Can you guys help confirm if there is a modem in the machine. (If not, then the seller lied to me)2. If there is, how do I get it working ? I did put a SIM card in the SIM slot in the back of the macine. I'm pretty sure it is currectly inserted. There is only one direction where I hear a small click, and the card stays in place.  Thanks Simon

Current Lenovo firmware for the EM7455 is 02.20.03.22, however Sierra Wireless has a newer version, 2.24.05.06 listed here: https://source.sierrawireless.com/resources/airprime/minicard/74xx/airprime-em_mc74xx-approved-fw-pa... After flashing with the newer version and rebooting, the card reverts back to 2.20.03.22. Has anyone else experience this? Is this something the carrier would dictate and enforce? Any help would be appreciated. Reason for upgrading is, when traveling internationally the unit has spotty connectivity and not very reliable. Hoping firmware upgrade would be a step in the right direction to resolving it.
