Cannot get on the internet after upgrade

Hi folks, a recent 'pacman -Syu' has left me without a working wireless configuration. I believe this is because I need to install some new package ('linux-firmware'?), but anywho, I am currently struggling with establishing a connection to the Internet via Ethernet.

Right now, I'm plugged directly into my modem, whose IP address is 192.168.100.1, netmask 255.255.255.0.

I have the following `/etc/netctl/ethernet-static` file:

Interface=enp0s20f0u1
Connection=ethernet
IP=static
Address=('192.168.100.20/24')
Gateway='192.168.100.1'
DNS=('8.8.8.8')

Then, I run

netctl start ethernet-static

which produces no output.

The output of

netctl status ethernet-static

indicates everything seems to be working so far.

Yet, from here,

ping 8.8.8.8

just hangs forever. I'm not sure what else to try.

Any help would be greatly appreciated. Thanks!

Re: Cannot get on the internet after upgrade

The typical cause is that you forgot to mount the /boot partition during the update, boot a dated kernel and now lack the kernel module driving the NIC because of that.
What are the outputs of

lspci -k
ip a; ip r
pacman -Qs linux
uname -a
