Problems?

If your raspberry still isn't connect, may be in one of these cases:

• Remember than SSID name and wifi password are case sensitive.
• If you use strange caracters in SSID name or wifi password then use wire connection and access to share network resource.
  Search the file system/recalbox.conf and edit wifi values.
• Use channels allowed in France or recalbox doesn't see your wifi network (example: in Spain channel 12 is allowed but not in France, this selection won't work).
  The solution is change wifi channel in your router.
