Denial of service attacks with rax80 router and iPhone 13

Since getting my iPhone 13 I have been getting the denial of service attacks. Always happens in the morning so it does not affect me. Netgear Armor says it has blocked the attack. NETGEAR Armor says that it was targeted to my Iphone13. My RAX80 has the latest firmware and my iPhone is up to date. Just wondering why this is happening. Rax80 firmware version is V1.0.10.140. This happens several times a week. Any ideas on what to do would be greatly appreciated!
