Vaio randomly reboots when Mac is on

  superspark 18:55 13 Oct 10

Can someone please offer me any advice?
I have a Sony Vaio laptop connected through a Belkin router.
It has Windows 7 64 bit and has worked perfectly for several months.
My son has bought an Apple Mac laptop 2 weeks ago which is also connected via the wireless router.Ever since the first day,my Vaio will randomly reboot and go directly to the screen which asks if I want to restart Windows normally or Safe mode.
i have found that if I block him from the internet using mac address filtering, then I do not get the problem.
Last night my other son who also has a Vaio laptop called and connected to my network as usual and the same problem happened to him.
Does anyone have any idea what the problem is?

Thanks very much...

Assuming you're not using a "Homegroup" with Windows 7 (which uses TCP/IPv6), try disabling TCP/IPv6 in both the Windows and Mac Laptops in case that's causing the Windows Laptops to crash.

In Windows, open the Network Connections folder ("Start > Run", type NCPA.CPL and click OK), right click the Wireless Network Connection and select Properties. Untick the box for Internet Protocol Version 6 (TCP/IPv6)" and click OK.

In the Mac, go to "System Preferences > Network", select the wireless adapter and click the "Configure" button. In the TCP/IP section of the next box, click the "Configure IPv6" button at the bottom and set it to "Off". [I only have Mac OSX 10.4 so later versions may differ slightly.]
