Query: U are forced to use Encryption to do Access Control (bad)

If u want to keep others from using ur router u HAVE TO use encryption [with a key] on this router to keep them out. Found this out through Dlink tech support. Other routers (Netgear, Linksys, etc) can do Wireless Access Control with MAC addresses or encryption. Use both if u want really secure control.Well, I don't want to bother with encryption and I don't want other ppl using my router. Can't do that with this router. I wish I had known this b4 I bought the DI-624.The indicator light interface in the front is very primitive. They are small, and blinking means normal. Usually blinking or a different color signals something is WRONG. There's only one colour. Kinda counter-intuitive.The latest e-manual is outdated and does little explaination of the features.
