I'm having an odd problem. I'm using a Raspberry Pi 3:--- I can connect to my Wifi and to WAN sites on Raspbian. And, on Alarmpi (Arch Linux) I can connect fine over ethernet.
However, on Alarmpi, if I try connecting via Wifi (various methods, netctl, wpa_supplicant, networkmanager), I can connect to my Wifi, and I can ping other machines on my LAN, but I cannot connect to the Internet (or ping WAN addresses like google.com or 184.108.40.206).
I'm really perplexed and Google searches haven't revealed anything of help.
