I'm trying to set up an Access Point on Wlan0 with Enet0 and Wlan1 (wifi dongle) as DHCP clients. I followed two excellent answers to set up AP with either eth0 or wlan1 as a client.
I'm using Raspbian Lite Stretch.
I first set up my AP with eth0 as DHCP client (success), NAT. I then attempted to add wlan1 as a DHCP client. Both eth0 and wlan1 successfully connect via DHCP, but wlan0 goes down and I'm not sure why. Ideally, I would want either eth0 or wlan1 to provide internet access to the AP.
