I actually don't like the wizards. I'd much rather have a dynamic (and error correcting) UI than wizards.
I'd argue the while most routers are mostly set-and-forget, users have to go back when something strange happens. Years ago it's when XBOX Live came out, you hand to tweak the firewall. Then WOW and other games needed tweaks.
IMO the worst thing is a set-and-forget...for a while focused interface because the next change might be starting from scratch. Then chasing your tail because you erase something you needed by re-using a wizard that crushes the old config.
The only thing keeping Edgerouters out of the true 'prosumer' definition (To me) is that they don't have a specific WAN interface labeled on the box and in the system.
