Why wouldnt you just have a Mac Filter for the wireless systems? Or under the Wireless advanced settings? I don't get it that I have to add my local area network systems in the filter that are wired into the freaking router. That makes no sense to me at all. The Mac Filter is for wireless systems... not systems that are within the house that are plugged into the device physically. Every other router I know or worked with sets it up that way, not like this. I thought this was supposed to be a top notch router. I mean if I have friends come over with their laptops, I happily would add their Mac address to my filter, but for some hijacking cracker outside my house walls trying to get in... that's what the security is there for. If my buddy uses a wire with his laptop to connect to my network LAN, why shouldn't he just grab a DHCP IP address? If he is directly plugged into the freaking router? Lol. I feel like the joker over this issue. Its ******ed... the way Dlink has it.
