    1. WAN setup: login via wifi, set the WAN address (see below for definitions of WAN)

    2. LAN setup: Connect WAN port to ethernet, login via elab network, check speed at speedtest.net

    3. Wireless options
    Channels:
    2.4 gHz has 11 channels, 20-40 mHz wide
    5.8 gHz has many more, 20/40/80/160 mHz wide, two sets of channels ~30, ~150

    Types of network:
    a=5.8 gHz
    b, g=2.4 gHz, b goes 11 mb/s, g goes 54 mb/s
    n=is a combination of a and g, 150mb/s
    ac=is the latest one, max speed is around 867 mb/s, fat channels

    Check your wireless status with option-fan on macs
    Look for:
    PHYS
    TX
    channel #
    channel width

    4. Access control
    MAC address
    hidden network

    5. NAT/DHCP, port forwarding
    If a client on the LAN uses your router as a gateway, you can forward traffic from the WAN to that machine specifically, like a web server.
    This is based on ports (like doors):
    80 = web
    8000, 8080, other web ones
    22=ssh
    548=apple file sharing
