</div> Thanks that fixed the non-ge00 interfaces. As to the abysmal performance with macosx over 5GHz wlan, that still is there, but I suspect the macbok to be the culprit here (plus the wlan connection is somewhere ion the edge between changing transmigrates so might be a moving target).<br>
<br>
<br>
Many thanks<br>
