The hardware button (hidden on Lenovo T420s), was switched off.
Sorry for this guys.

No problem - some times it is easy to think that the switch is on, when in 
reality it was toggled to off.  The give away in your log was this:

[64525.131109] iwlwifi :03:00.0: L1 Enabled - LTR Disabled
[64525.131401] iwlwifi :03:00.0: RF_KILL bit toggled to disable radio.

I apologise, but I'm extremely dubious of this claim. 

wifi doesn't stop working when you simply update the Portage database - there 
is no connection between the two things.

You updated the Portage database (with `emerge --sync`) *and then did something 
else* which caused your wifi to stop working.

Surely, you updated the Portage database (with `emerge --sync`) and then 
installed a bunch of updated packages?
(something like `emerge -u world`)

I don't mean to sound antagonistic, or like I'm attacking you. I'm sorry if 
this email has a negative tone, but what you wrote raises two issues. 

1. It's easier to help you if we know exactly what you did.

2. When you're updating a bunch of packages, you should run `emerge -p` first. 
When you've done so, there's a good case for identifying system-critical 
packages (such as anything related to wifi, networking and system init) and 
emerging them separately (`emerge -1 package`); then you can deal with the 
package notices or any problems separately, knowing exactly what update you're 
responding to.

Your wired interface seems to be up, while your wireless one seems to be
down. Do you normally have both interfaces up?

If you are using openrc, what is the output of:
root# rc-update show | grep net
