I just got the new iMac that of course has wireless capability. Now I need to figure out what to do with my old iMac G3. I want to move the G3 upstairs with the new iMac downstairs and on the other side of the house and have both connected to the internet. I currently have comcast cable internet at I'm not too sure of the speed I am supposed to get. I have a cable modem that is at least 5 years old so I'm not sure if that is a limiting factor. I get a little less than 3 Mbits/s downloads on this modem. What's more ideal? Wireless router or dealing with comcast and being able to set up possibly 2 IPs on the same line with 2 cable modems? Obviously wireless is more flexible, but I won't be using it except for something that could have been done with another modem depending on comcast's work through. Theoretically, the wireless should have higher maximum speeds than I can get from comcast anyway right? I guess the main question is whether comcast allows multiple IPs. (I could call them but they are a pain in terms of customer service).
