Wireless network security

[#1]

I have a Edimax BR-6204Wg wireless Router 802.11g 54Mbps
Watt is my MAC address on the Screen Shot, I knoe that the information is there, but where?
I got the Screen Shot by following the information that I got from PlusNet.
Finding MAC address
Clicking Start > Run
Typing cmd and clicking OK.
Now type ipconfig /all to find your MAC address.
[Edit]
The link to the router.

Physical Address is you MAC address. Every network device has a unique address consisting of 6, 2 character hexadecimal values, often separated by -

Well I put that in to the router and it didn't like it!

But note that restricting wifi access to a particular MAC address will not enhance your security by very much.
If you are using an easily crackable security scheme such as none at all or WEP then an attacker can inject packets with your MAC address in them.

Try the MAC address halfway down - the other one at the bottom is the MAC address of your disconnected ethernet port.

Looking at a user guide the MAC entry seems to be entered as a continuous string of 12 digits, i.e. no hyphens, etc.  Did you enter it without punctuation?

Well if I can get it to work it will be better than none!   
I have the Firewall on plus Zone Alarm Firewall on as well

Yes and the router locked me out! I had to do a router reboot.

Yip-eee I got it to work it was the first one not the last one!
[Edit]
Whoops thank you both of you for your help.   
[Edit]
The router is on full stealth plus Zone Alarm Firewall on as well in full stealth as well boy am I happy, I am on

Sorry to knock you off your cloud.
But that is like a child closing  their eyes, and saying now you can't see me!
What you have done, is great protection from casual attacks. But some encryption even if it is only WEP would also be helpful.
If your hardware supports WPA that that would be best.

Full stealth is very good for protecting you from internet malware attacks. It doesn't protect you from someone sitting outside your house intercepting your wireless signal with a cracking type attack.
Your MAC locking will stop the casual person who just wants to hijack the nearest wifi signal.
Wifi is a security pain.
If you feel confident:- try the following
1) Change the default password on your router.
2) Install WEP or WPA - either will stop the casual person.
WEP can be easily broken in a couple of minutes, WPA is much harder to crack.

I can testify to this.  I have just returned from six weeks in Canada.  I had my lap top with me and was able to use my email and surf wherever I went (I travelled 5,000 miles) with ease, just by turning on the laptop and scanning for an unprotected WiFi network.  I was probably risking my own laptop security but I only had innocuous emails and files on the hard drive, so no real worry; my important data was all on a stand-alone external hard disk.
But it goes to show just how easy it is for a stranger to use your WiFi network if it is not protected.  I did not take advantage by downloading masses of data, because I would have been stealing bandwidth which may have been capped.
So any Canadians reading this, if any of my connections were through your WiFi, many thanks !  And sorry you did not do better in the Rugby.

I definitely am not closing my eyes.  I take internet security very seriously indeed.

[snip] I agree- install WPA if your equipment supports it.

To be honest with me bean dyslexic I don't know watt the equipment supports!

[big snip] Change the default password on your router.

That was the first thing I did!

How do I do that? and where do I get WPA from?

[#13]

Currently you are safe from the average person who just wants to leech on your internet connection. They will move on to an easier target if they simply want internet access.
However, at present all your data is being sent on your wifi in clear text - it could be read by anyone with a laptop within wifi range.
Whilst it's easy to get paranoid about this, it is fairly easy to arrange for your wireless data to be encrypted. This is where the WEP or WPA protocols come in. There will be an appropriate interface in your PC drivers/network interface and in your router settings.
Basically, you need to set up a passphrase which is used to encrypt the wifi data.

On the Routers Security Settings page I get:

Quote

Security This page allows you setup the wireless security. Turn on WEP or WPA by using Encryption Keys could prevent any unauthorized access to your wireless network. Encryption :    Disable WEP WPA pre-shared key WPA RADIUS WPA Unicast Cipher Suite : WPA(TKIP) WPA2(AES) WPA2 Mixed Pre-shared Key Format :    Passphrase Hex (64 characters) Pre-shared Key:

Please see the Screen Shot 1 and Screen Shot 2 as well.

Will I need any software on the PC ?

It needs updating, but my website has a few pointers that might help:

WPA is the only real way to secure your network, but all the other things can make things more difficult.
