Vista machine on LAN - Round 2

My Vista (32) SP1 laptop that had connectivity problems which were fixed a month ago has now developed another problem: At some point during the day, it will simply get "tunnel vision" and see ONLY the Internet, nothing on my LAN. Other computers (3 - all running XP Pro) cannot 'see' the Vista machine either where prior to this happening they could. At NO time do the XP machines lose connectivity to the Internet or the LAN or each other.
The previous laptop problem involved a wired connection instead of the usual wireless connection that Vista apparently enforces. Once I fixed that problem it remained stable for almost three weeks. Turned out that the IPv6 driver needed replacing with an update (that only RadarSync was able to tell me)(NVIDIA nForce 10/100/1000 Networking Controller).
As my wireless Access Point is still down, I am forced to connect using a CAT-5 cable through a switch to my router. When directly connected to the DSL modem, I stay connected without a hitch. When I am in my computer room I am back to the chain of equipment as before. All cables have been swapped with cables running to the XP machines as well as swapping slots in the switches. Pulling the CAT-5 plug out, pausing, and plugging it back in will only disconnect & connect the Internet connection but not reconnect to the other computers. I have checked the properties for the wired NIC and verified that nothing can put it in power-down or sleep mode. I do not put my laptop in sleep or hibernation at all - the most I do is let the screen go blank after 10 minutes of inactivity.
Results of a PING on the Vista machine to any of my XP machines will give me "The ping request could not find host 'xxxxxx'. Please check the name and try again." ('xxxxxx' is the name of any of my XP machines). It is almost as if the XP machine names have been deleted from the hosts file - but they come back when I reboot.
If I reboot the laptop the full connectivity comes back: to the LAN/Internet and all the XP machines. I can pass files/whatnot between them freely. At some point pretty much every day, the Vista laptop will 'remove' itself from the LAN and remain hidden from the other machines until I again reboot it.
I wrote a tiny program and tries to access the laptop every 20 minutes and put it on one of my XP machines. Once connectivity is lost, it alerts me. Usually, this happens while I am busy on an XP machine and have neglected the laptop for varying amounts of time. MY error message is "The laptop disappeared again!"
Is this just some sort of Vista glitch that has no real fix or is there something I've failed to check? I've seen loads of posts here detailing a lot of IP configuration/driver issues and have read each one with an eye to solving this latest headache.
