I'm moving into a new place in a heavily populated area (security, yikes!) and I thought I'd ask for advice. It's a 3 flat OLD apartment building in Chicago, and I don't want to run wires all over my apartment. First off, I will be using Comcast High Speed Internet. I also currently have the Microsoft Wireless G Router that I'm using with my work laptop. I can't use WPA due to using Win2k on my work laptop. 1) In my living room, I have a PVR and PS2 that I will want to connect to my network. 2) In my den, I have 2 boxes (one xp, one linux) that I will want to connect to my network. 3) I also have a work laptop that I can use on the Wireless network throughout the apartment. 4) The PVR (ReplayTV) can connect to one of my PC's with software and I can record shows to my PC if the connection is quick enough. My question is, what is the advice on the most secure way to share a cable modem and network all of my devices through my apartment without using wires with the layout I've explained? Should I go wireless or go with an electrical networking solution between the two major points (living room and den)? I will basically need two hubs (one in the living room, one in the den). I typically turn on my wireless only when I'm using it due to the security concerns. Thanks for any help!
