Fairly simple problem I hope?
Using Vista Home Premium, I've a Linksys wireless modem, two PCs hard-wired to it, a laptop using the wireless access facility.
What I'm looking for is some software (preferably freeware

) that will allow me to control (from one of the hard-wired Pcs) internet access on the laptop ... that is, limit the bandwidth available to the laptop, or even deny access completely, in the simplest, most painless way possible.
Any ideas please?
