1Gbps. CAT5e has double the requirement to provide 1Gbps. I bought a<br>
bunch of CAT6, thinking it would support 10G ethernet over copper. That<br>
never happened and doesn't look likely today.<br>
<br>
So ... if you don't have a reason to have more shielding or thicker<br>
cables, CAT5e (not just CAT5) is absolutely fine. Save the money.<br>
<br>
Can anyone correct me?<br>
