Disconnection problem between My NetGear Router and Ipad

Hi, I would like to know opinion of users and a solution maybe... 

 Since I installed my new Norton 360 version on my 2 Ipad it seems like connexion problems happens: my Ipad are suddenly deconnecting from my wifi for maybe 30 seconds. anrd reconnect after. What could be the reason? 

I'm using Apple Ipad 8 and I bought this new version of Norton 360 on February 2021.
