> In this way can I also use D7000 also for LAN?

   If by "LAN" you mean wired connections, then yes.

   "LAN" = Local-Area Network.  That includes wired and wireless
connections.  The "LAN" Ethernet ports on a router are labeled "LAN" to
distinguish them from the "WAN/Internet" Ethernet port ("W" = Wide).

   Wireless clients are on the same LAN as wired clients.  It's easy to
put a "LAN" label on an Ethernet port, but it's hard to put a "LAN"
label on a wireless connection, so many people think that "LAN" means
"wired".  But it doesn't.
