You can find error code here :

-2 seems invalid params (is you ssid ou password has special character or space? if yes, try without, there's problem with special character now.)

and always post xbmc.log,
if you want effective help.

Quote:There are no spaces in my SSID

When i look to your screenshot, there's space and special character in it.
That's the problem.
ps :
'SSID, local ip adress is not a secret data, and you don't have problem with your security by giving us', so if you have problem with wifi, don't hide it, it can help to diagnose (like this case).
