I've now bought 3 of these for clients and I look and an idiot for trusting Cisco.
Cisco isn't putting any effort into their stuff any more.
I tried setting up a vlan for a public wifi to separate from the wired lan with the shipping firmware 1.0.15.
Unfortunately this firmware is incomplete. They're missing the feature to setup the dhcp and network settings for the vlan subnet.
When you upgrade to 1.1.21 it fixes this but now they're still missing the dhcp client list for vlans.
I've tested this on all 3 and they're all the same. In addition to this I can't get the optional port to work.
Just unbelievable how poor this device was created.
