<p>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 (;-))</p>
<p>What's a good approach? I have considered<br>
</p>
<ul>
<li>MAC address lists, <br>
</li>
<li>no wi-fi (strictly wired doesn't work with solid concrete
walls), </li>
<li>a second router with a more secure protocol (<i>is</i> there
such a protocol? And will my wife's Mac speak it?))</li>
<li>something I haven't thought of<br>
</li>
</ul>

<p>[The usage never runs me over my limit: I think someone is using
me for downloads that might put <i>them</i> over their limit]<br>
