Bug Description
Reproduced with 2 Lenovos with the same Hardware ( Lenovo S205 with Ralink 3090 Wlan Card)
- Wlan works perfectly on Live-System
rfkill list (on Live-System)
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
2: ideapad_wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
- Wlan is impossible to activate after Installation (System thinks Killswitch is on)
rfkill list (on installed System)
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: ideapad_bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
Solution: Reset of BIOS. Further Tests: Apparently the "Ubuntu" Device, created by a fresh Installation of Ubuntu (using the whole Harddisk), MUST NOT be on First Place in the Boot Sequence.
Error can be reproduced by changing the Boot Sequence (Put "ubuntu" back on first place).
After removing "Ubuntu" to the secon place in the BIOS-Boot Sequence rfkill list shows the same values as in Live-System, an Wlan works again.
