Cela étant dit, peut-être que ce problème (récurrent visiblement, cf. plusieurs forums) sera réglé avec la MAJ 7.0.1 Bugfix !...

@acris Salut !

Idem, malgré le paramétrage de mon wifi, le statut reste déconnecté (depuis la MAJ 7.0).

Mon matériel :
RPI3b / Recalbox 7.0.

Ma config : 
# ------------ B - Network ------------ #
## Set system hostname
system.hostname=RECALBOX
## Activate wifi (0,1)
wifi.enabled=1
## Set wifi region
## More info here: https://github.com/recalbox/recalbox-os/wiki/Wifi-country-code-(EN)
wifi.region=JP
## Wifi SSID (string)
wifi.ssid=Livebox-F786
## Wifi KEY (string)
## after rebooting the recalbox, the "new key" is replace by a hidden value "enc:xxxxx"
## you can edit the "enc:xxxxx" value to replace by a clear value, it will be updated again at the following reboot
## Escape your special chars (# ; $) with a backslash : $ => \$
wifi.key=xxxxxx

## Wifi - static IP
## if you want a static IP address, you must set all 3 values (ip, gateway, and netmask)
## if any value is missing or all lines are commented out, it will fall back to the
## default of DHCP
;wifi.ip=manual ip address
;wifi.gateway=new gateway
;wifi.netmask=new netmask

# secondary wifi (not configurable via the user interface)
;wifi2.ssid=new ssid
;wifi2.key=new key

# third wifi (not configurable via the user interface)
;wifi3.ssid=new ssid
;wifi3.key=new key

## Samba share
system.samba.enabled=1
### Virtual Gamepads
system.virtual-gamepads.enabled=1
### SSH
system.ssh.enabled=1

Si t'as la solution, je suis donc preneur ! Merci à toi,
