I have a Rogers-supplied router and cable modem package, which twice has shown significant usage when I was out, once with the original unit and once with their replacement Cisco. That makes me suspicious of the current state of authentication for wi-fi schemes (and I use the term "schemes" advisedly: they used to horribly leaky (;-)) What's a good approach? I have considered * MAC address lists, * no wi-fi (strictly wired doesn't work with solid concrete walls), * a second router with a more secure protocol (/is/ there such a protocol? And will my wife's Mac speak it?)) * something I haven't thought of --dave [The usage never runs me over my limit: I think someone is using me for downloads that might put /them/ over their limit] -- David Collier-Brown, | Always do right.
