Re: Issue on Lenovo T480s update Fibocom WWAN L830-EB firmware V18300.1002.00.01.01.17

Dear customer,

I talked with WWAN engineers and they want to know more information about below;

 

  1. What was the SIM card used?
  2. What is the APN profile of the SIM card?
  3. Did the issue happen even before update to FW17?
    (Based on the comment, issue happened even after rollback to previous FW14 or FW11.
    But I would like to know if issue also happened even before FW update to FW17.

Thank you for your reply.

It is a general telecomm 4G sim card with phone and network.

The APN will AUTO setting by SIM card just like the photo.

 

The issue never happen before FW17(2018/11),before that  I  could use the Internet normally and could setting APN by myself

Than I tried to rollback to previous FW14 or FW11 ,but "No Service" and not found APN settting function.

 

Some people have the same issue, you can found in this forums, everyone thied to downgrade to FW14 or FW11.

Also can not work even within DRIVER downgrade.

Dear AAWJdnx,

I got some comments from WWAN team,

 

>2.When I put in SIM card ,The Windows Settings -> Cellular network become to "No service",,than Advanced options can not be APN setting.

 => Does this mean you cannot manually add APN profile via Settings -> Network & Internet -> Cellular ->Advanced options -> Add an APN?

       Can you provide the screenshot of Cellular -> Advanced options page when the issue happenes?

Yes, Add APN Setting is MISSED!

Just like no SIM card. If I downgrade to V14 or V11 , it is the same.

Hi AAWJdnx,

I am Lenovo engineer handling this issue.

 

Thank you for providing the screenshots.

Based on that, our current assumption is that your SIM card is not detected properly  by the laptop.   

 

We already asked help from our team in TW.

But unfortunately, they cannot reproduce this issue using Fibocom L830-EB + Taiwan Mobile SIM.

 

For further isolation, may we ask for the “exact” details of the SIM card you are using so we can ask them to purchase and check?

  • Network Carrier: (Taiwan Mobile?)
  • SIM card name: (Kindly provide exact name if possible)
  • Others: (e.g. Traveler SIM? MVNO SIM? Etc.)

 

BR,

WWANGUy

I think this issue may not related to the sim card.

I also have this issue when I using China Unicom in China after this firmware upgrade.

I notice that there is a process after the firmware upgrade. (baseband or something? I am not sure.)

After that every sim card was not available, I try to use the sim card of China Telecom was still the same situation.
