I've been lurking here for a few months and this is my first post. There is a similar post on the ASUS support forums that I am watching but I thought that I would check over here as well. I used the search function but couldn't find anything similar on these forums. I was trying to get the router setup last night and had some issues loggin into the router's GUI to set up security, etc. I was working from a Dell laptop running under Windows 7 Home Premium 64-bit and using IE. Using the browser got me exactly nowhere. When I used the setup wizard, it told me that my PC and the router were on different subnet masks. I didn't look up the computers subnet mask, in part, because I didn't know what I was supposed to do with that information. I went through all of the troubleshooting tips in the manual but none of them helped. Has anyone experienced or heard of a similar problem? Any suggustions would be appreciated.
