Apple TV crashes internet upon startup for 5 minutes

Hi - We

just got the Apple TV 4K and are having a weird problem. When Apple TV is

plugged in and setup and we turn on our TV (Samsung), our internet completely

crashes. After about 4-5 minutes everything reconnects and once it reconnects,

everything that was connected to wifi works perfectly (including the Apple TV).

I thought it was the Apple TV but we bought another one and are

having the same issue. What's weird is that we used to have a Roku stick and

didn't have any issues - it's only with the Apple TV. Internet also only drops

when we turn on the TV (which boots up Apple TV) but not during any other time.

I have the Apple TV right next to my Verizon Fios router and

again, haven't had any issues prior to using Apple TV. I've tried looking at my

router settings and have upgraded firmware but can't figure it out.

Has anyone else ever had this problem? Thanks, Jeff
