Perhaps I'm missing something obvious, but what does the following LAN setting in a Router do/refer to?
"IP Reserved for Internal Usage:"
From network administration point of view, the wireless access point is integrated with the router, which runs on IP address 192.168.1.1 by default. The reserved IP address, i.e. 192.168.1.2 by default, should not be used by anyone except for the WRVS4400N router itself. This is due to the way the router and access point were developed and integrated historically.
The internal IP address is resevred for the integrated access point inside the WRVS4400N.
