Note the patch to change the list to a whitelist has been included in the Fedora kernels starting with kernel 5.0.10-300, so if you have an For this please run: 'sudo dmidecode &> dmidecode.log' and send me an email at with the dmidecode.log attached. If this works your model should be added to the new whitelist. In this case please check that the 'Hard blocked' setting for the 'ideapad_wlan' rfkill device properly shows no / yes based on the switch position. Please run 'rfkill list' if this contains 'ideapad_wlan' in the output then you are using the ideapad-laptop driver. If you have an Ideapad or Yoga laptop with a wifi on/off slider switch on it. But this is a small price to pay to make sure that as of yet unknown and new Ideapad models do not have non-working wifi because of this issue.Īs said the whitelist for models which do actually have a hardware rfkill switch is currently empty, so I need your help to fill it. the GNOME3 UI would report 'wifi disabled in hardware', where as now users will just get an empty list of available wifi networks when the switch is in the off position. This does lead to a small regression on models which do actually have a hardware rfkill switch, before this commit they would correctly report the wifi being disabled by the hw switch and e.g. This whitelist is empty for now, meaning that we define all models as not having a rfkill switch. To fix this I've submitted a patch upstream turning the huge blacklist into a whitelist. Worse as mentioned not being on the list for a model without the hardware switch leads to non working wifi, pretty much leading to any new Ideapad model not working with Linux until added to the list. Just in the 5.1 kernel alone 5 new models were added. The same firmware interface is still used on new Ideapad and Yoga models and since most modern laptops typically do not have such a switch this dmi blacklist has been growing and growing. So I added a dmi blacklist for models without a hardware rfkill switch. It turns out that in this case the firmware interface reports the non-present switch as always in the off position, causing NetworkManager to not even try to use the wifi effectively breaking wifi. Sometime later a Yoga model using the same firmware interface showed up, without a hardware rfkill switch.

This driver was written on an Ideapad laptop with a slider on the side to turn wifi on/off, a so called hardware rfkill switch.

Once upon a time a driver was written for the Lenovo Ideapad firmware interface for handling special keys and rfkill functionality.
