The bypass capacitor you added is not enough to allow it to run WLAN without brownouts. you might want to add a 220+µF electrolytic. you have more than enough space and the GND flood fill isn't really needed since the module has an internal GND plane. You even should have enough space for an LDO through hole voltage regulator.
Also a few of the pins you broke out aren't that useful so it might leave them out for better routing
