I have the 8.4 uconnect and the fix I used last time was disconnect the phone and forget it from the system. I reset the wifi system in the radio menu. then I held both buttons in for ten seconds, the volume and tuning knobs and let go, when I let go it powers the radio down, I see the ram logo and it fades away. then I turn off the vehicle and open the drivers door and leave it open for 60 seconds or a little more than that. Then I powered up the truck and reset the wifi back to the name and password I have in my phone and then reconnected my phone. My earlier post on this is more accurate since it was right after I did it and it has worked since. Good luck.
