My network properties says "Security type: No authentication (open)" But encryption is WEP with security key.?

Question

I'm pretty sure we had to type the password before connecting any computers to the wireless network. But the "No authentication" thing is confusing. I'm using WEP encryption with a security key. Is authentication (WPA...shared... whatever those mean) necessary to make sure my neighbors aren't using my internet?

Answer 1

Authentication is one of the WEP's biggest security flaws. It says No Authentication, because WEP doesn't have authentication. It doesn't authenticate the wireless connection.



The key is the password. When a hacker use security tools to attempt to break a WEP key, his first step is to send a fake authentication to establish a null session on your wireless network. Then he attempts to try to disconnect people connected to your wireless. Doing this forces computers to reconnect to the wireless network to obtain a special packet from the key exchange call an Initialization Vector or IV. This IV is where a piece of your WEP key is stored. The hacker then gathers enough of the IV's to crack the WEP key. He only needs 20,0000-50,000 packet IV's to crack your key. This process would only take him 5-10 minutes.



IEEE created WPA wireless standard with "authentication" and a different security mechanism to patch all of WEP disadvantages...



I recommend you use WPA2-AES. WPA2 is the authentication and AES is the encryption. WEP's authentication is open, in other words it's clear and "open" to be seen by others. Like an open window, people can see in and wind can blow inside. WPA shuts the window, WPA2 shuts the window and pulls down the windowblinds.



Hope this helps

Answer 2

Security Type Wep

Answer 3

Authentication and encryption are two different things. Authentication is only available if you are using WPA Enterprise and a RADIUS server. You can still use WEP or WPA PSK encryption without authentication.



Edit: WEP encryption is weak. A knowledgeable person can crack it. It's better than no encryption but if your equipment supports WPA or WPA-2 with a pre-shared key, that will be MUCH more secure. As long as you use a long, random pre-shared key, WPA is extremely difficult to crack and WPA-2 is essentially crack-proof.

Answer 4

I have a WEP connection with a network security key but the security type is open. Now there is another person who is using this net connection. Is there anyway that I can change the wi-fi settings for my computer to make it more secure without changing this other person's and still use the wifi? I want to use the settings that Chameleon talked about - WPA2-AES. Please advise.

As long as your wireless network is password protected then your neighbors will not be able to use your router.
