Hello, I am trying to set up a home network. I have been using the free version of Zone Lab but because the Pro has a networking feature I downloaded the trial version of that and have installed it on both computers, only two computers will comprise the network. Both of these computers are notebooks, and have only one Ethernet connection. I use a Cable Modem that has only one Ethernet connection. I bought a NETGEAR five port Ethernet switch and have attached the cable modem to connection 1 of the NETGEAR switch. I have attached one notebook to connection 2 of the switch and the other notebook to connection 3 of the switch. I can always get only one of these notebooks to connect at one time. It is always the one plugged in first, after connection 1 (it can be 4 and 5 and 3 and 4) Either notebook will connect to the Internet but as soon as I connect the other, if it is in position two, or before the other, the second notebook will disconnect from the internet. The other will continue to work. I have tried the ipconfig /all On the notebook that is connected I will get a Gateway IP DHCP IP and two DNS IP's On the notebook that is not connected I will get an Autoconfiguation IP and a SUBNET of 255.255.0.0 Gateway blank nothing else. On the connected notebook a message Autoconfiguration enabled Subnet 255.255.252.0 and the the Default Gateway IP, DHCP IP, and to DNS IP's So now I am stuck. I would like to make this a network of two so each has access to the internet. The NETGEAR switch allows for ethernet connections to the two notebooks. Lights on the NETGEAR switch light up when either or both of the notebooks are plugged in. Trying to get a repair connection through Control Panel Network Connections, the light of the computer that does not have access to the internet will flash while Network Connections seeks to do the repair, but ultimately it will fail and tell me it cannot set up a connection. So it seems that both notebooks are connected to the switch. Zone Alarm on the unconnected notebook will tell me a New Network has been set up giving me the Automatic Private Address configuration IP and a SUBNET of 255.255.0.0 Same as I find in the ipconfig /all It's always one or the other connected to the internet, with the one cutting of connection when the other is established. Whichever is connected to the first connection after 1 on the NetGear switch always has priority, and cuts the other off. Then I have to disconnect the cable modem and switch the cables around if I want to other Notebook to be connected to the internet. The one that was previously connected will fail of course. One notebook has Windows XP Home with SP1 the other has Windows XP Pro Media Version with SP2 Both seem to connect and disconnect exactly the same.
