Hi Lin,
It depends..., but please describe your intended deployment further for the best answer.
If you have 8 Unleashed APs in a network now, they all have WLAN details and the same
version of firmware. And they all have IPs in the same VLAN/subnet with the same default
gateway address too. You could also configure a specific Mgt IP address, that they would
all know to use for Master AP identification too.
If you separate this network into smaller pieces, you will need a router default gateway and
use the same IP address/netmask... it could be tricky.
Unleashed is designed to be simple to setup, but you need to be on the defaulted AP's
Configure.Me-XXYYZZ wireless SSID to configure the first AP, which sets up the network
and becomes your initial Master AP.
But perhaps if you know your remote network IP subnet/mask and def-gw, you might be
able to configure your Unleashed AP with a static IP address (outside any DHCP scope
used there), that you could connect to and configure before sending to the remote site?
