Security on wireless networks
Here are 4 basic rules for a "wireless" relatively secure.
- Change the default SSID
- Avoid broadcast SSID
- Encryption
- Filtering by MAC address
- Notes and thanks
Change the default SSID
By default, the network is called by the company that makes equipment. For example, a wireless router "link-sys" appoint its network link-sys. " We must change the name.

Filtering by MAC address
If your WiFi router allows it, enter the MAC address of each of your equipment in the router.
(The MAC address is unique to each WiFi device in the world.)
Thus, only WiFi devices reported in the router can connect.
security WIFI ( 802.11 or Wifi )
let me Explain you the important concepts of security WIFI .
- An appropriate infrastructure
- Avoid defaults
- The MAC address filtering
- WEP - Wired Equivalent Privacy
- Improving authentication
An appropriate infrastructure
The first thing to do when setting up a wireless network is to position intelligently access points depending on the area you want to cover. It is not uncommon that the area is largely covered actually bigger than desired, in which case it is possible to reduce the power of the base station in order to adapt it to the area to cover.
The MAC address filtering
The MAC address filtering
Each adapter r é bucket (generic name for the NIC) has a physical address of its own (called MAC address). This address is represented by 12-digit hexadecimal grouped in pairs and separated by dashes.
The access points generally in their configuration interface to manage a list of access rights (called ACL) based on MAC addresses equipment allowed them to connect the wireless network.
This precaution a little binding can limit network access to a number of machines. In return it does not solve the problem of confidentiality of exchanges.
WEP - Wired Equivalent Privacy
WEP - Wired Equivalent Privacy
To address the problems of confidentiality of exchanges on networks without son, the 802.11 standard includes a simple mechanism for data encryption, it is the WEP, Wired equivalent privacy.
The WEP is a protocol for the encryption of 802.11 frames using RC4 symmetric algorithm with keys with a length of 64 bits or 128 bits. The principle of WEP is to define in a first time a secret key of 40 or 128 bits. This secret key must be declared at the access point and clients. The key is to create a pseudo-random number with a length equal to the length of the frame. Each data transmission is encrypted and using pseudo-random number as a mask through an exclusive OR between the pseudo-random number and the weft.
The session key shared by all stations is static, ie that to deploy a large number of stations WiFi it is necessary to configure using the same session key. Thus knowledge of the key is sufficient to decipher communications.
In addition, 24-bit key is used only for initialization, which means that only 40 bits of the key 64-bit really used to encrypt and 104 bits to 128 bits key.
In the case of the 40-bit key, an attack by brute force (ie trying all possible keys) can quickly bring the pirate to find the session key. In addition a flaw detected by Fluhrer, Mantin and Shamir on the generation of pseudo-random chain makes possible the discovery of the session key to storing 100 MB to 1 GB of traffic created intentionally.
The WEP is not sufficient to ensure effective data privacy. However, it is highly advisable to bring out at least a 128-bit WEP protection to ensure a level of confidentiality minimum and avoiding in this way 90% risk of intrusion.

Which model of wireless netgear router are you using. Password setup for different versions of routers can be different. Please specify the router model for which exact password configuration can be adviced.
Re: Security on wireless networks
i have netgear wireless router MR814 v 2tw hope this helps i have tried going on change advanced settings and then clickin on wpa and followin instructions but not doing it i must be doing something wrong i did set password up lastime but 4got how i removed password by resetting router by pressing in button at back had to do this coz someone got password(person who fixed my laptop gave it to all street lol)thats why i need to put new one on thanks hun 4 ur help

Just get into your router and select Quick Setup from there and set the password for you router.
