Hi All,
I'm installing Arch on a Thinkpad X220. I've done this before on several other X220s and never had any issues.
I'm able to connect to wifi when I'm booted from the usb stick, and I'm able to do pacstrap successfully. However, when I reboot the new installation, my wifi connection authenticates and immediately deauthenticates. Here is the output from dmesg:
[ 175.315745] wlp3s0: authenticate with 14:ed:bb:5d:1e:79

Here's the info about my wireless card and driver from lspci -k:
03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 [Condor Peak]
Subsystem: Intel Corporation Centrino Wireless-N 1000 BGN
Kernel driver in use: iwlwifi
I've gone back and booted from the LiveUSB multiple times, and when booted that way the wifi connection is stable. I've checked that the kernel module parameters for iwlwifi and iwldvm are the same when booted from usb vs. the SSD.
Thanks in advance for any input.

I fixed the issue by installing dhcpcd. But I would like to learn more. Should this have been installed when I ran the following line from the installation instructions?
# pacstrap /mnt base linux linux-firmware
I don't think I've ever manually installed a dhcp client on past installs. Is this a recent change?

Yes it is a recent change https://www.archlinux.org/news/base-gro … -required/
It is covered by the updated installation guide under "software necessary for networking".
