My Thinkpad 410s laptop has been working fine, running Ubuntu for quite some time. Yesterday, my wifi stopped working out of the blue.
rfkill list and it shows the wifi adapter as blocked both on the software and hardware levels. I've ran
rfkill unblock all, and this gets rid of the software level block.
However, my laptop doesn't seem to have any hardware level "block wifi" button. Does anyone know how I can re-enable my wifi? I checked the BIOS, and wifi is enabled there. I don't think anything physical happened to my wifi card, I believe the problem is software related, but I haven't find any software method to solve it.
Update - I forgot to mention this, but I have no obvious wifi button on my keyboard, even when counting FN keys.
