It's also worth mentioning that most home WiFi routers are sit behind your ISP's internet router/gateway and has a private ip addr that is NAT'd so your home WiFi router cannot be connected to directly from the Internet by a nefarious actor.
What you really should be keeping an eye out for is for CVEs, security updates and security settings for the actual internet router/gateway device that is directly connected to the Internet. Other than that, as long as you're using the highest level of WiFi security available, a strong password and not broadcasting your SSID to 100 apartments nearby where some curious tech savvy kids live, you shouldn't have to worry too much about your WiFi router.
