Most routers don’t last 7 years, especially LinkSys brand. They last 3 years.
We hard wired our household LAN, so no worries about wireless hackers.
I have wifi but ethernet to main servers and those servers have neither bluetooth or wifi on.
I’ve gone through them as fast as one year. Of course I have a LOT of devices and a wifi6 router. Netgear, TPLink, etc. I now have Asus. Was not thrilled with Ubiquiti.
I did the same thing with my two homes and one business.
Vastly improves the security and I can monitory all three remotely.
Ubiquiti.
