Sometimes putting my phone in Airplane mode for 5-10 seconds and then turning it off resets the connection and allows me to wirelessly connect to the device. If that doesn't work I will try turning the computer's wifi off and on too. Sometimes it works, sometimes it doesn't. I'm on Giraffe and was able to connect wirelessly two days ago, and now I can't connect at all!

Recently I wasn't able to connect wirelessly to my main computer, and it wouldn't work until I connected to a different one.
