Option 2. WDS. Second Router is on its own and connect to the first Router
via Wireless.
Buy a Pair of Wireless Routers that can do WDS (Zexel, SMC, Belkin have
models that do WDS as is out of the Box.
Linksys WRT54GL can do WDS when flashed with DD-WRT firmware.
Using a Laptop loaded with Netstumbler, do a Wireless survey in the house,

According to the Netstumbler's signal strength reading, identify spots that
have strong signal. and spot with weak, or No signal.
Evaluate how you can cover the space and start placing WDS units.
Additional Wireless Routers in WDS Mode (Wireless Network - Configuration
Modes. ) has to be placed in spots were the signal is good about Half way to
the dead spots.
How many WDS units are needed? It depends on your specific environment (that
is a good the reason to buying WDS units one at the time, try it, and decide
on the Next step).
Otherwise.
