Question: Asus router (RT-AX86U Pro) I'm using as my main and is fully supported. I have a older RT-AC68U that I'm using as a Mesh Node with a wired back haul(out of support) Does it matter that I'm using an older device? I'm I putting my network at risk? My first thought was that the RT-AC68U is not using its firmware and using the main router instead therefore it should be safe?? I'm really not sure maybe someone can advise?
