Comment 0 for bug 1832435

This problem appears when you first install ubuntu 18.04, 18.10, and 19.10 on a Lenovo Miix 501 laptop. I have not tried previous versions of ubuntu. After installation or update to a newer versio of ubuntu the network adaptor is set to off and cannot be turned on. I believe this is because of a non-existent or faulty driver for the intel 8260 wifi adapter. It also could be that the driver is waiting for physical or keyboard switch to turn on the adapter. However, no such switch exists in this laptop model.

The problem can be resolved by adding "blacklist ideapad_laptop" to the configuration file

/etc/modprobe.d/blacklist.conf

(this is for ubuntu 19.04. The filename and location are different for 18.04 and 18.10)
