No lease, failing
Failed to bring up wlan0.
at this point i brought up a wireshark… did a capture, there were no dhcp requests seen. To rule out switching preventing my laptop from seeing the requests, i turned off another device on the network while capturing and i DID see its DHCP requests…
I captured on the laptop wifi connection and the USB network connection to the DC to see if they were coming there… nothing…
sooo… still looking…
