Apple's routers are based on VxWorks. So if you trust VxWorks' networking, then you can trust Apples routers.

Personally I trust VxWorks over some patchwork router of the week by the usual vendors. It's used in many safety critical/medical applications, including the mars rovers.

The downside being that VxWorks has very low resource requirements, so some vendors use them to cut resources. Hence, You'd better be happy with the factory provided configuration because you can't flash them.
