User requirements:

(1) Cover the whole house with wireless signal.

(2) Provide wired connections in 2 separate areas (up to 100 ft apart).

Equipment:

(1) Router 1 (used to connect to the modem) can be any router (wireless)

(2) Router 2 has to be DD-WRT compatible (Buffalo routers, e.g.)

Setup

The 2nd router can be set up as a wireless repeater, or wireless bridge.

As a repeater, the key points are:

- WAN IP: DHCP from router 1 (router 1 IP 192.168.1.1) - no need to specify

- LAN IP: On different subnet from router 1 (192.168.2.1)

- Enable DHCP for router 2 clients

- Physical interface: SSID = 1st router SSID

- Virtual interface: SSID = different SSID

- Set up wireless security on router 2

(the figure below is for a repeater bridge)

As a bridge, the key points are:

- WAN IP: 192.168.1.2 (static on router 1 subnet)

- LAN IP: router DHCP pass on

- Disable DHCP on router 2 (router 1 will do the work)

- SSID = 1st router SSID

- No wireless clients for router 2
