I am having the same issue. Using a Linksys WRT54G wireless router with two laptops (XP Home and XP Pro) and a desktop (XP Home), can all connect to the internet, but not to each other.
I can ping the router, but not the other computers. In fact, on an XP Home machine, I don't even get a response when I ping myself (the computer I'm on). How much sense does that make? I can ping myself on the XP Pro machine without any issue.
I've setup networks time and again on NT, 98, 2K, and XP Pro. This is the first time I've really messed with XP Home. The Windows Firewall is turned off. Is there some other setting I'm missing? It has to be something really simple that I'm missing.
