I've a customer who operate a small internet center, and they would like to have a WiFi router with the possibility to use a passphrase (it's easier to give a password like "tomato" to his customers than giving them a 16 Hexa digits password).
Even thought it's not "required", it would be nice to have a feature to block the access to some web sites, based on an internal list, or a public web site list (like BarracudaCentral for Spam).
Of course, it's an internet center and the router will be placed in a locked cabinet, so it's important that the router doesn't require a "reboot" every 2-3 days because it has some major failure in it (ex: WRT54G in is earlier days had this problem. Even South Park laughed at their face in an episode of their show).
Thanks for your recommendations, i really appreciate
