Hey john, you make me laugh :)
I have been there this weekend and what I could find was not the best :/
situation:
WAN -> WAN
OPT1 -> (direct line)PoE switch -> several ProCurve M5M310 AP and Linksys (was installed years ago by a company) (IP 192.168.2.xxx)
LAN -> simple (dumb) switch, from here it goes 4 ways: (IP 192.168.0.xxx)
1: phone box (currently disabled)
2: to reception -> dumb switch -> computers, printers.
3: to office -> dumb switch -> printers, computers
4: camera
the ISP is even more horrible then i thought, they got a DSL line that has a maximum of 28Mbps and if we are lucky we get 6Mbps at night.
I have told them to change this ASAP this month, and going to change this to a 125Mbps line to start with.
