I do believe the 'typical' home router is insecure, but mine is rather typical and has had great security updates for 4 years now.[0] It's definitely nothing special, just a $100USD unit. Asus also has an autoupdate feature so their owners don't even have to do anything. I haven't used another brand in years, I had a Buffalo router before this, but I've been following the release notes on this one and security seems top notch for a low-end home router. I do run a 3rd party firmware on this, but its downstream from Asus's.
