have an hw rfkill switch, resulting in wifi always reported as hard

As bypass I did a modprobe -r ideapad-laptop

[Kai-Heng Feng (kaihengfeng)]

The description says "Y720-15IKBM" but your machine is "Y520-15IKBM". Can you confirm the latter one is what you want?

[L Sluijter (lsluijter)]

Hi.

Sorry I was not clear. This is my machine:

loek@loek-Lenovo-Y520-15IKBM:~$ cat /sys/class/dmi/id/modalias
dmi:bvnLENOVO:bvr5XCN13WW:bd09/07/2017:svnLENOVO:pn80YY:

ct10:cvrLenovoY520-15IKBM:

*Please contact Ike Panhc <<email address hidden> <email address hidden>>,
I think he is already working on the same problem.*

There is an Y720 as well. Perhaps Lenovo could give you a complete list of
the new September models.

Regards,

Loek Sluijter

[L Sluijter (lsluijter)]

Any outlook when this will be fixed for Ubuntu? I see it is still not there in linux 4.18.
Suse LEAP 15 fixed this within 6 weeks after I reported it to Suse.

[Ike Panhc (ikepanhc)]

I thought this has been fix a long time and now find out we need Y520-15IKBM (not IKBN) as well. I assume that you need Y720-15IKBM in blacklist too. Is it?

[L Sluijter (lsluijter)]

I am interested in the Y520-15IKBM, but there is a Y720-15IKBM as well.

This is how it has been fixed by SUSE: drop the N from Y520-15IKBN so it becomes Y520-15IKB

[Ike Panhc (ikepanhc)]

Thanks for your report. I am going to send this patch for upstream review and also think a good plan to blacklist all future ideapads. According to latest suggested design laptop vendor shall not have a physical radio switch.

My Lenovo Legion Y7000 also has no wifi. Please add it too.

@wxwok,

Could you show the output of `cat /sys/class/dmi/id/chassis_version` please?

Just want to make sure there are spaces or not.
