I am using the Wireless Home Networking modem offered by Bell Sympatico (it is a Siemens SpeedStream 6300 for non Bell users). This modem has five ethernet ports on the back (one of which can be selected as WAN or LAN), a USB port and a game console serial port. The modem is also a wireless router. Before I start with my question the first thing to know is that I am NOT using the wireless features yet. I am using the WIRED ethernet ports on the back. I have a PC and a Mac (AIO G3) - both are able to connect to the Internet through the modem no problem - but they are not able to see each other on the network. I have networked PC's and Mac's before and it is usually very simple and this is making me crazy. Is it a modem issue (the user guide says "SHARE FILES THROUGH A HOME NETWORK")? Is it because it does not support Mac (even though I am able to connect to the Internet Bell tells me it can't)? Do I require an extra router connected to the modem (which is also a router) in order to share files? Any experience getting this modem to work this way would be greatly appreciated. Tech Info: Mac AIO G3 w/ OS X 10.2.8 PC w/ Windows XP Home SP1 Thanks in advance.
