Anyone here have experience with the LG Smart 360n?

For months I was offering free wi-fi, occassionaly.  The device has an "Isolate
Clients" option that was/is enabled.

A photo of the config screen here:

But recently, I fired up a new laptop of my own, connected to the wi-fi, and I
was able to see all the machines and their directories on my whole network!

What the..

Can I officially proclaim that the islolate clients feature is broken?
