Now am all wireless and that, i feel the need to protect some of my College files and folders, and my personal folders, and as i dont know if i have managed to secure my network effectively as of yet, i decided to encypt some folders, but i dont seem to be allowed to perform thi feature;

That feature is reserved for XP Professional. But if you want to encrypt data, try PGP (http://www.pgpi.org/products/pgp/versions/freeware/winxp/8.0/)

I think you may have the wrong end of the stick here...

You need to enable data encryption for the wireless network so that your internet/network traffic cannot be intercepted. This is called WEP (Wired Equivalent Privacy), which is a secure protocol. It can be turned on via the Network card/router.

Read this for more Info. (http://kbserver.netgear.com/kb_web_files/n100684.asp)

Oh god no, i turned that on earlier and i was way out my league, it took me 1 hour to enable the WiFi card again. I did figure some new stuff for the network, it can be confusing at first, after installing the suggested Programme from Neteru, that is only really for encypting files that only people with the same key cn read, or so from what i gather, its all new to me, and therefore sorry if yu dont understand, and me not being the worlds best explanationist (made up word) i do appologise.

I am still worried my network is not secure, although i live in a very poor area and not many people even have broadband let alone a wireless network, i dont feel i am in an immediate threat from hackers etc, but still... the network IS open.

"WEP is not necessary if you have a gaming console such as PlayStation or Xbox, and there are no other computers on the network."

Assuming this quote is reffering to only two compnents conecting to the router, my Playstation2 is connected via Ethernet. But the only other componenet is not a desktop PC, its a Laptop using the wireless network, so therefore i think the WEP is necesary!

Yes, WEP is nescessary if you are really worried about security. Particularly if you use your credit card online or use online banking etc.

Another way of increasing security is to stop the signal from leaving the house by using a reflector. It also has the benifit of increasing the signal strengh to the rest of the house. An antenna can be made with a Pringle can :D

Have a read of these articles.

OMG information Overload!

I use internet banking excessively and i have numerous credit cards with numerous banks.

I am quite scared now!

I think i am unable to set up this network securely, i might have to get some outside assistence, as i dont eve have time to read all this information!

What is this, i was trying to confiure/figure out this secure network when i suddenly encountered a freeze of my system, when this appeared;

I have to end the process manual via task manager to recover :S

Dr Watson is a program debugger. When the Application crashed it starts up to capture the crash information. Not much use unless you are the programmer.

I the short term I wouldn't worry too much. There has to be someone in a approx 200m radius (depending on how many walls you are transmitting through) of your house deliberately trying to intercept your signal and decode it.

I think i managd to set up the WEP feature, but whats open shared etc mean;

I dont know which two i should select for best security, as i dont really know what the other two mean on this image;

New Technology File System.
Either you have your hdd in Fat 32 (File Allocation Table), or in NTFS. NTFS is the Windows New Technology (since Windows NT / 2000) of placing the data on your harddisk. It is much more efficient.

As it turns out, I've misunderstood what Sparky was after I think (because of the image posted). He was after something else not to do with the image.

Open - security (encryption) is switched off.

Shared key - security on and you then have to generate a key.
Set Authentication Type = Automatic
Encryption Strengh = 64 (good) 128 (better, but slower)

You are asked to enter a Pass phrase. Type in a name and when you press generate it will scrable your letters and generate 4 unique hexidecimal Keys.

You can then setup Shared Key on your notebook using the keys generated by the router. The router and notebook both have the same shared encryption keys and can now cryptically talk to each other.
