eHome Networking Wireless G Broadband Router

I agree that it was easy to install and seems to be working correctly but when I put security on it, I can't access it at all. I tried to find a tech support line but none of the info that came with it is still active. The email address for eHome isn't there anymore, I tried going onto Dlink since eHome is a division and they don't have this model anywhere under their line of products. I just need to know why even I can't access it once it's secure. I'm sure it's something that I didn't do (I'm not an IT person by any means)but I need someone to tell me what that may be. Good product...bad support.
