Yes I know all about VLANs and Trunking. There is only one VLAN.
Netgear didnt argue with me when I explained it and they are
overnighting me a replacement (which is good, I expected them to argue
with me for a while, they were actually rather helpful so I give the
customer service a good rating). Hopefully I can talk mgt to allowing
a Cisco switch in my budget and have this one as a "backup"
Thanks for your help and support.
