Fedora on X1 Extreme Gen 3, WWAN Fibocom L860-GL 4G/LTE-Advanced Cat 16 not working

2020-10-18, 14:57 PM

Hi,

 

I just received my new X1 Extreme Gen 3 with the WWAN-Module in the Subject. After installing Fedora 32 (either with or without Secure Boot, Kernel DMA) it wouldn't allow me to connect to 4G.

I also checked BIOS I/O Access for WWAN support, it is on.

 

Google told me that there are alot of Problems with Linux and Fibocom L850-GL (the older model). There are related to PCIe / USB Connection errors in Linux.

 

Could you help me getting this to work? I don't wan't to use Windows.

 

Thanks in advice :)

What I understood is that Lenovo does not support WWAN on Linux. They were/are working on it, but it needs a lot of work to get it working.

 

If you look at the configuration options for the X1 Carbon on Linux and Windows you can see that the WWAN option is only available with Windows.

 

I understand that you bought a X1 Extreme Gen 3 without Linux support, because this support is simply not there. But then you take a risk. Don't believe the hype, created by the Lenovo marketing department, that Lenovo supports Linux all over the place. This is simply not true. They are progressing only very slowly into the right direction.

 

In my dream world, customers stop buying Lenovo-laptops to run Linux, until the Linux support has arrived. That could be a incentive for the Lenovo management-team to really support the Linux-project. And, as an extra bonus, once the support it there, Lenovo can see in their statistics how great the demand for this support really is.

I'm sorry, but that is gonna be hard. This post gives some more information on the subject. At least you know that a lot of people are working on it. So in the end it will work, probably. 

Oh, and once you've found your solution, please share it here. So others can profit from it too.

Hi @smiles1314 

 

WWAN is still work in progress - but we really are working on it (I was in a meeting reviewing it this morning). I think it's fair to say it's taking a longer than expected.

 

 - The L860 PCI driver is being upstreamed. My understanding is there are still some issues around suspend and resume that are being worked on. Having this driver available should resolve one of the issues we had with the previous L850 generation where you had to switch it into USB mode to get it to work under Linux (if you followed the hacks).

 - There are some patches needed in the kernel to support the sensors that then control the transmission power (needed for FCC regulations) that aren't accepted yet.

 - There is a closed source binary application that is needed for modem support. This is under testing and isn't available yet - once testing is complete we'll need to release it in as open source friendly a manner as we can.

 

I want to highlight however that WWAN is being worked on for the X1Carbon8 and X1 Yoga 5. The X1 Extreme is not going to be officially supported in this first round.

 

There are a number of reasons for this - some are technical and some are cost related. Doing WWAN support for a platform, including certification and testing is quite complicated and expensive. The team working on this want to make sure they get it right on a couple of platforms first as we do it for the first time; see how popular it is; and expand the program after. 

 

I suspect people will find ways of getting it to work (they did for the L850) but I want to set the expectation that Lenovo won't be officially supporting the X1E initially.

 

Feeding back to @Loesje comment about not buying Lenovo until we get it right. I really hope we are getting a lot of things right but I know it's not perfect and I think we're learning fast from the bits we get wrong. I hope we have some awesome products where Linux now works flawlessly (that's our aim!) but when there are issues like this - raise them and let us know - we need to know what we're getting wrong so we can fix it. 

 

If there is a way to properly measure Linux interest in WWAN please let me know - I think based on the feedback I hear both on forums like this, and from corporate customers, that the program will likely grow. Hopefully the work we're doing means you can enjoy Linux on your hardware with confidence in the mean time:)

 

Thanks

Mark

Same issue here; I have Thinkpad T14 gen1 with intel processor. I bought this wwan module because it is whitelisted by the bios. It works without any configuration in Windows. I keep Windows around for testing, but I use Ubuntu on a daily basis. 

 

 

I hoped that this module would work with Ubuntu out of the box. Fibocom even mentions Linux specifically as supported OS for this wwan card...

Do you have the problem scheduled or better how long you will need to get this fixed? I think this is a serious issue for Lenovo Flagship Laptops, that the WWAN ist not working in Linux and many other Firmware Devices are not recognised (In Fedora 33 specially). I’m not sure if I get the most out of my new Nvidia GPU, since every Boot it shows mit that NVIDIA Kernel Modul is missing. Could you please check if the firmware is running properly for Thinkpad X1E Gen 3 under Fedora?

I have T490s, and it seems the WWAN is not recognised in the system. Fibocom L850-GL or L830. Any ideas how to install in Fedora 33?
