WiFi resetting daily

Hello,

I have the latest XR1000 gaming router (option wasn't availble to select).  Almost everyday or every other day, I need to reset my router.  All the lights are on the router as if I'm getting a connect but my wifi isn't working.  If I plug into the lan the internet is working.  So around 5am my wifi stops working and I know this without checking because my security camera goes offline.  I don't have any fancy setting.  Matter of fact it's the same setting as if you turn it on right out of the box.  I've done a factory reset multi times and it still hasn't fix the problem.  

Any thoughts that would help solve this problem?

Thanks,

Brew
