I have a NixOS system (nixos https://nixos.org/channels/nixos-18.03). Using wpa_supplicant, I can't get my wireless card to connect to my home network (WPA2).
It's using the new Systemd Predictable Network Interface Names scheme (wlp2s0 replaces wlan0).
A) Following NixOS Manual / 11.6 Wireless Networks, I set a WPA sid and passphrase.
$ wpa_passphrase ESSID PSK > /etc/wpa_supplicant.conf
$ systemctl restart wpa_supplicant.service
The wpa_supplicant module can be either active
$ systemctl status wpa_supplicant
● wpa_supplicant.service - WPA Supplicant

Either way, I still can't ping a web address.
$ iwconfig

enp0s20f0u2 no wireless extensions.
enp0s31f6 no wireless extensions.
B) I also played around with manually setting the SSID and passphrase. But no dice.
$ iwlist wlp2s0 scan
$ iwconfig wlp2s0 essid <mysid> key s:<mypassphrase>
C) I dug around the internets, and found people with similar issues. But those solutions don't work for me (bring down, flush, up wlp2s0, rebind with wpa_supplicant).
$ ip link set dev wlp2s0 down
$ ip addr flush dev wlp2s0
$ ip link set dev wlp2s0 up
$ wpa_supplicant -B -i wlp2s0 -c /etc/wpa_supplicant.conf

Did you ever get this resolved @Nutritioustim? – tcelferact – 2019-10-20T15:29:41.410
1@tcelferact In this particular case, I had to buy a different router (unrelated issue). Turns out that the new router works fine with my NixOS box. I'm sure there was an underlying issue there. But I never pursued it after that. – Nutritioustim – 2019-10-23T14:12:50.130
