I have the same problem (a little different although.
My XP205 worked well till I update the Wi-Fi password of my router for security reason.
So I reset the printer (shut down, keep press "i" and press power on for 5 seconds (both keys) , than release both keys).
My printer now is not configured with any WiFi net (just printed with "i"the network sheet)
But there's no way also with WPS to pair it with 3 mac and 1 ipad!
After a lot of blinking (orange/green etc) onl;y the orange blink to the infinite....
i need to send the config to that printer, and I don't want to do this with a PC (windows).
Ideas ?
Tx in advance
