I have a Asus wireless router in a closet in the middle of our house (wl-520gu). On the north side of our home lives all the devices needing to connect to wifi (PC, TV, tablets, etc.)...on the south side is where all our bedrooms are, including the baby's room. Without getting into a debate about the safety of wifi signals, I'd like to ask if it is possible to block (or severely reduce) the wifi signals emitted to the south side of our home while keeping the signals sent to the north side? Is there a material or technique I could use to accomplish this?

you could put a powerline ethernet adapter in the closet and on the notth side of the house and move your router to the north side. your signal would come from your broadband connection, to your cable modem, out the cable modem ethernet port, in to the powerline adapter ethernet, through the house electrical wires to the second powerline adapter, out its ethernet to your router (now on the otherside of the house)

here are some on newegg

http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=powerline+ethernet+adapter&N=-1&isNodeId=1

- the tin foil should also work and is pretty cheap
- most people use the directional antenna to get better range, I do think it would work and you can put...
sure, you can replace the antenna with a directional one an focus the beam in the direction you want.
google "directional antenna for router"

you can also put up a mini faraday cage on side of the router you don't want your signal to cross.
In this case you would use a wire screen connected to your electrical ground to act as shielding from the router.
I would just put it a foot or two behind the router in the direction you want to block and check with a laptop to see that the signal is degrade. google faraday cage

tin foil will work well also

I have an old electro static bag my motherboard came in...I wonder if that is actually a mini Faraday cage....I'll give it a try...but if that doesn't work... Do you have any ideas how well the cheap direction al antennas work off eBay?

- most people use the directional antenna to get better range, I do think it would work and you can put shielding up also to block the signal that get thru.

- you can even just cut out a piece of a aluminium soda can and attach it directly to the antennas of your router to shape the signal. here is a example: http://www.wikihow.com/Make-a-Wi-Fi-Booster-Using-Only-a-Beer-Can
you can try it in a few minutes. should work well for what you are doing. Sheild your signal on one side of the house and extend the signal on the other.
