I have a new laptop with a centrino wireless card.
I installed ubuntu on it and all seemed fine until I upgraded the kernel, and rebooted.
My wireless stopped working despite toggling the wireless button.
rfkill list returns the following:
0: phy0: Wireless LAN Soft blocked: yes Hard blocked: no 1:hci0: Bluetooth Soft blocked: yes Hard blocked: no
the hardware switch only toggles the hard blocks.
How do I turn off the software blocks? I have tried
rfkill unblock all
without success. What next?
