Hi

I have a laptop that connects to t'net via a wireless connection. The modem is plugged into my main computer.
I want to be able to get files from my main computer on my laptop, and visa versa and I'm sure this can be done, but I haven't a clue what to do.
I've tried setting up a network but it didn't work so I was wondering if one of you kind souls could post an idiots guide on how to do it please? Assume I haven't done anything and don't know anything please

Is your modem a USB one or a standalone modem and router? Doesn't make that much of a difference to setting up the network but maybe a little.
Are both computers windows XP? Run the set up a home or small office network wizard on both PCs. Make sure you enable file and printer sharing and also make sure they are on the same workgroup. Then you should be able to see the PCs in my network places both PCs should be there on both PCs - their names will show up, click on them and it will open and show the shared docs folder. You can either just use these folders by dragging stuff in, or you can share other folders by right clicking on them and clicking sharing..
If you wireless network isn't secure then be careful what you share. And if it is secure, with either a WEP key or a WPA-PSK key, be aware that they can be broken easily, so if you have a particularly high security job or something, don't share the files
