Vista dropping out?

[Slime101]

Can anyone shed some light as to why the only vista laptop in the house keeps dropping out and refusing to connect to the network?

We have 2 XP laptops, a wireless print server and other machines that all work flawlessly but the vista one perpetually drops out and refuses to connect.

I read that IPV6 can cause some issues but cant be removed so i followed a guide to disable it but no change...

Any suggestions???

It now seems that some of our XP machines are dropping out too, and my repeater upstairs has problems connecting.

Any thoughts as to why, its driving me nuts and more to the point, "her" sitting next to me keeps expecting me to fix it!!!

Nobody got any ideas?
