Hi,
I'm not a novice with PCs, but setting up a wireless home network is driving me nuts. Please can anyone recommend any websites which take newbies through the basics of networking (inc wireless) in a methodical manner?

I have a Trust 485a Speedlink Wireless Web Station (an external ADSL modem/wireless router combi) which has been connected to my main PC (WinXP Pro) by ethernet cable for over a year without problem. It's been excellent. The wireless connection has only been used when my brother calls with his laptop (WinXP Home) - always connects first time and he can use my broadband Internet connection without any problem.
Now my son has acquired a wireless-enabled laptop (WinXP Home) and wants to connect via the wireless router. The laptop shows that it is receiving an excellent signal from the router, but he just can't connect to the Internet. We've tried all the WinXP settings and gone through the home networking wizard without any success.
I'm trying to find out how our network should hang together.
Should the wireless router send an internet connection to any wi-fi PC within range? Should the router only send an internet connection to my main PC, and all other wi-fi PCs access the Internet via a home network centred on that main PC? The router has an in-built firewall - do we need to run other firewalls on each PC? We have ZA running on each PC, but even with ZA switched off the laptop can't connect. I need to know how all this should hang together in order to start making sense of it. I can't understand how my brother's and my son's laptops are so different when it comes to connecting.

Any pointers would be very welcome. Thanks.

The WiFi router will communicate with anything (suitably configured) that is listening. So yes in answer to your question the wireless router should an connection to any wi-fi PC within range giving access to the router and through it to the internet.
"all other wi-fi PCs access the Internet via a home network centred on that main PC" - not relevant, the internet connection is being provided through the router to all PCs, not to some PCs and to other PCs through an intermediary PC.
I prefer to have SW firewalls on the PCs in addition to the HW firewall in the router. They compliment one another.

As you have an established internet connection with the wired PC, and wireless strenght is good you might be looking at problems with encryption on the wireless link (is WEP switched on, if yes is it switch on in both router and PCs wireless adpator cards and have approrpiate keys been entered on both rotuer and cards). Do you see the router SSID from the PCs?
