Re: Network visibility question

[Jeff Crosby <jlcrosby@xxxxxxxxxxxxxxxx>]

I tried that, Scott.  Nothing shows up.  There are 18 wireless access
points (16 warehouse, 2 office) and 2 switches (1 office, 1 warehouse) in
that range.

I'm checking now with the installer to see if they have some offsite router
"interfering" with this.

This installer no longer will support this for us.  They installed it 4
years ago and have decided if they do not control a customer's entire
infrastructure, they will support none of it, so we were summarily dropped.

They have already pledged to help the new support company (of which we
already signed a contract with) to get everything moved over.  There are 3
SSIDs involved, 2 still working and 1 not working because their router has
it "isolated."  I was just trying to learn what I could in the meantime.
