The question really is how elaborate homenet wants to be. Given how i suffered for a good while due to broken transceivers in LAN equipment resulting in persistent 0.5% loss on links, i would like homenet to be a lot better than your average enterprise network is on this.
Sure, in my case there was ECMP, so one COULD have done intelligent routing changes. But more often than not, alerting the user is the primary action to take. "Check the cable on portX/routerY. You may need to try a different cable" "Put the poor AP further away from the microwave" I really can't see how to build successfull home wireless without good diagnostics and suggestion system. Some of the higher end home AP vendors seem to start doing this with smartphone apps as the user interface. PowerLine equally has a lot of gotchas. I have also seen crazy things like failing linux-PC starting to blast multicast packets, killing a whole LAN segments until the PC rebooted. Sure, a lot of enterprise switching gear can throttle this, but alerting the user should be even more important.
