i currently have a compaq pc running windows xp and connected to ntl/virgin broadband 10 meg.
I bought a compaq vista pc yesterday and 2 devolo plugs , which are supposed to let us share the internet and other files.
my problem is that i can only get one computer or the other to access the internet using these plugs.the other computer starts saying that there is a problem with ip address or unable to get network address.if one is working the other is is very frustrating .. can anyone help?

Unless you are using a ROUTER, only one PC will get an IP address from the ISP and have internet access. When you install a router, it gets the single IP address from the ISP and allocates IP addresses in one of the ranges reserved for Local Area Networks to computers connected to it, most commonly a 192.168.x.x address. It then "routes" the internet traffic to the appropriate computer in the network.

If you are not using a router, you can connect one PC to the internet, network the two computers and then enable "Internet Connection Sharing" on the actual internet connection (modem connection) in the "host" PC.

To enable “Internet Connection Sharing” in Windows XP, open the Network Connections folder, right click the actual internet connection (modem connection), select Properties and then the Advanced tab. Tick the box “Allow other network users to connect through this computer’s Internet connection”.

When you enable "Internet Connection Sharing" on the Internet connection, it automatically configures the network adapter used for your "Home Network Connection" with the IP address and subnet mask If you have more than one adapter available for this purpose, e.g. both a "Local Area Connection" and a "Wireless Network Connection", you will have a drop down list from which to select the appropriate adapter. The "Client" PC's Local Area Connection should be set to get its IP address automatically, which it does by DHCP from the "Host" PC. Also, if you run the Zone Alarm firewall in your "Host" PC, the Internet Zone Security level must be reduced from High to Medium or "ICS" traffic will be blocked.

I have devolo plugs too, and 3 PCs, one connected to broadband, with a Belkin modem. I've been able to get 2 of the 3 PCs to connect to the Internet simultaneously, and they work OK - bit slow, but that's probably BT broadband.

But I have a problem which sounds like yours - 'A dLAN adaptor with this security ID is not addressable..' is what it says, in spite of the fact it worked before. It's maddening and I'm hoping someone can sort it out. It is I think a software problem as sometimes I've used XP's network command to 'repair' the LAN.
