My wifi went out and now my litter robot won't reconnect

My wifi went out last night and this morning I tried to reconnect the litter robot but it wouldn't reconnect so I tried to onboard it again and now it won't connect to my WiFi at all. It says the password is wrong but I have tried it 10 times and made sure it's the correct password each time. I've only had this thing for 3 days this is really annoying
