One thing you might do is limit the number of users that can logon to your network through the router settings.

Good idea. Also, assigning IP addresses manually and disabling dynamic allocation is something I've done.
How much of a performance hit is enabling WPA Calum ? ?
Umm . . . no idea, lol. I've not used it without encryption much, and my internet is only 2Mb/sec, and I don't share files across their network.
So I'm not really sure how fast it is as I've never tested it.
When I get home later today, I'll use Sandra to benchmark it.
great, thanks!
Happy to help.
