Photon Won't Connect To Wifi

Hi all, first time photon owner here and having some difficulties. I just got my Photon and would like to connect it to my wifi, but I can’t get it to connect. I’ve tried via the mobile app and via the command line, but no dice. The error message I get in the command line is ‘! Something went wrong: Serial timed out’. Thoughts? Any help is appreciated!

Did you get the device id when you hit ‘i’ in the serial console? If not, check if your console has hardware flow control turned on, set it to off if so.
