If I use a wall of aluminum can that block wireless signal?

Question

Yeal im serious. So if I use a wall of aluminum then can that block wireless signal?

I want to know. If not then what can I use to block the wireless signal from going through the wall.

like this
---------------------WALL
-------> <| Wireless signal not here.

Will aluminum block or enance the signal if there is a little wall of aluminum.

WEP is not going to help because it can be cracked.

Answer 1

No of course not.

Try usin WEP Key from the router (build in)
Set a password to it.

See if your router comes with a CD, install the software or...

default configuration is... (type on address bar)

http://192.168.1.100

or

http://192.168.1.1

or

http://192.168.0.1

or

http://192.168.0.100

(depends on your router) please refer to your router manual. Router recommended -- AZTECH, LINKSYS

If you layer it a couple times, it WILL completely block Wi-Fi signals.


I'm guessing you're trying to prevent a neighbor/roomate from using your internet bandwidth. If this is the case, you might want to put a WEP key on your router. It's basically a password needed to connect.

Depending on the make of your router, the sequence in doing so will be different, so you'll have to explore your router's settings a bit until you find it. When you DO find it, just enter in whatever code you want, and make sure that you can remember it and that nobody else can guess it.


To get into your router's settings, type this in the address bar:

192.168.1.1

It may ask you for a username and password. If it does, enter this:

User: admin
Pass: admin

This is the standard for most routers, unless you know you've manually changed the password, youself.

Once you're past the password screen (if it even asked you for a password), then navigate yourself through all the menus (don't touch any settings that you aren't familiar with) until you find the WEP settings. Enter the password you wish to use and apply the settings. You will most likely need to reconnect, and it'll probably ask you for the password at that point.

And don't worry about the WEP being cracked. Be sure to pick something that isn't even a word. If it's not a word found in a dictionary, it's a LOT harder to brute-force.

If push comes to shove, you can also block the MAC address of the person you're trying to keep from accessing your router. This will completely deny this person access to even enter a password to try to connect, unless they have seperate NIC cards, in which case you can just block the MAC addresses of those, too.

Hope this helps. If you need further assistance, feel free to contact me. Good luck!

Your best bet is to wrap your wireless router in aluminum foil. several layers, preferably. If you can, use some sort of grounded wire mesh instead of foil.

Next, put a microwave oven next to your router. Punch a few holes in the front of it, and point it at the router. Make sure that it points AWAY from your reproductive organs.

This should prevent anyone from haxoring your megabits.


Seriously though, if you're trying to block the signal, something like a few foil would work. Idealy, however, you want something that's grounded. If you put foil around your router, or on the walls in the same room, it'll just reflect the signal all over the place, and you'll end up generating noise for yourself, and you'll have all sorts of problems with what's called 'multipath' (the same signal arriving at the transmitter or receiver at two different times). This is sometimes an issue with routers near walls in houses with aluminum siding.

Answer 4

Why do you care if it goes through a wall? Do you have a clue what it would cost to put aluminium on your wall? So you have a clue how fast you will become single (if not already single) for spending money on aluminium for your walls?

Stop the drug abuse.

I think turning on the security feature would be more economical and far less geeky.

Answer 5

it will not fully block the signals but it will reduce the signal strengths.
Also if it will be very thick it can fully block signals.

U can use mac address authentication for wireless acees point by this only authorised people can use the signals.

Answer 6

aluminnium foils do work but blocking the MAC is more practical and technical. do this.......
block all MACs except urs. this way, nobody except u will have access to ur router.
happy routing!!! :-)

Answer 7

I would reccommend wrapping your whole house in tinfoil
