Set up a D-Link,Linksys,Netgear,3com WiFi Router to Use with Your Laptop

In general, the process of installing a WiFi device to use with your laptop begins by connecting the router to the same computer that is attached to your broadband modem (in this example, your laptop); this allows automated configuration software to obtain the information it needs without any intermediary devices along the way.

Here is a typical setup:

1. Turn off the power to your broadband modem.
   If there isn’t an on/off switch, remove the power supply to the device.
2. Connect the power adapter to the back panel of the wireless router.
3. Plug the adapter into an AC outlet.
   Check that the power LED illuminates.
4. Connect an Ethernet cable to the broadband modem.
5. Restore the power to the modem.
6. Insert the other end of the Ethernet cable into the WAN (wide area network) port on the back panel of the wireless router.
7. Insert another Ethernet cable between LAN Port 1 (on the back panel of the wireless router) and any available Ethernet port on the NIC (network interface card) of the laptop, which you’re going to use to configure the WiFi system.
8. Shut down the laptop.
9. Restart the laptop connected to the WiFi router.
   Let Windows fully load.
10. Open your Web browser.
11. In the address bar of the browser, type the URL for the built-in setup screen of the wireless router.
    For example, type http://192.168.0.1 for most D-Link routers.
12. Press the Enter key.
    The below table shows a list of the standard addresses for setup screens as well as default usernames and passwords from several major makers..
    
    

    Router Manufacturer	URL	Default User Name	Default Password
    3com	http://192.168.1.1	admin	Admin
    D-Link	http://192.168.0.1	admin
    Linksys	http://192.168.1.1	admin	Admin
    Microsoft	http://192.168.2.1	admin	Admin
    Netgear	http://192.168.0.1	admin	password

    
    
    Depending on your device maker, you may have to enter a user name such as admin (for administrator), and you may have to enter a password.

Wireless Encryption Techniques - WEP, WPA, and WPA2 Overview

1) WEP :

Each packet of the Encryption has 24bits Initialization vector. Which unfortunately done in plaintext.

40bits (encryption)+ 24bits(init. vector)=64bits Encryption.

104bit(encryption)+ 24bits(init. vector)=128bits Encryption.

WEP uses RC4 stream encryption, for a fresh key stream for each packet.

The Init Vector & the key are combined to get per-packet key which is used to generate RC4 keys stream.

The RC4 is one of the major culprits in the security issues.

Part of the weakness of RC4 has to do with the combo of Init. Vector and Plain Text chipper.

24 bit Init vector is finishing a cycle of 2 in the power of 24 in about hour and then repeats.

Repeating Init Vector plus knowledge about the plaintext language, makes guessing the plaintexts simpler.


2)WPA:

It is an interim solution that is used now until 802.11i comes out.

It still using RC4, but the Key was changed to TKIP.

TKIP basically works by generating a sequence of WEP keys based on a master key, and re-keying periodically before enough volume of info. could be captured to allow recovery of the WEP key. TKIP changes the Key every 10,000 packets, which is quick enough to combat statistical methods to analyze the cipher.

TKIP also adds into the picture the Message Integrity Code (MIC). The transmission’s CRC, and ICV (Integrity Check Value) is checked. If the packet was tampered with. WPA will stop using the current keys and re-keys.

The Future (probably in mid 2005 will come with the release of 802.11i).

The Big Change will be Advance Encryption Standard (AES).

802.11i will change the WPA RC4 usage to employ AES.

Referred to as WPA2 the main difference for regular user would be.

WPA uses (as describe above) TKIP/MIC Encryption.

WPA2 uses AES-CCMP Encryption

AES aka the Rijndael algorithm is a secure, fast symmetric cipher that is easily implemented in hardware.

AES has its own mechanism for dynamic key generation. It's also resistant to statistical analysis of the cipher text.

Counter-Mode/CBC-MAC Protocol (CCMP) called the Advanced Encryption
Standard (AES).

WLAN working - WLAN Tutorial Basics

Five basic processes will explain you How WLAN works:

1) Scanning - process of finding the network. To use any kind of network, you need to find it first. With wired networks, you have to find a cable or jack on the wall. In wireless world you need to identify an appropriate network. Stations use scanning to find existing networks in the area. After scanning, a station can choose to join one of the BSSs.

In scanning procedure there are seven parameters. Most wireless card drivers use default settings for these parameters. You could change only few of them. I will give you a short description of these parameters, so you could know what they mean.

a) Type of BSS. There are two BSS Types: Ad Hoc and Infrastructure Networks.

b) BSSID - can be an Individual or Broadcast. Access Point chooses which BSSID it will transmit. If AP uses Individual BSSID, then it is “invisible”. Broadcasted BSSID can see all stations in range.

c) SSID (network name) – string by which clients can associate to a specific network.

d) Scan Type is active or passive. Active and passive scanning uses different frames. With active type you can save your battery.

e) Channel List - Scan can use Probe request or listen on a specific channel.

f) Probe Delay - delay in microseconds, before active scanning begins.

g) Minimum and Maximum Channel Time - Minimum and Maximum time before station scans particular channel.

2) Joining - process doesn't guarantee you network access. After joining you need to authenticate and associate, and then you are on the network.

There are two ways how station can join to particular BSS (read Access Point):

- Station can choose BSS manually.

- Automatically - based on power level and signal strength, the station will decide to which access point will join. Parameters on station and Access Point need to match.

3) Authentication is the most discussed issue in wireless networks. In wired networks, physical access to network is the biggest security issue. In wireless world you cannot restrict physical access to network, so you have to use Authentication. It is not mandatory, but my biggest recommendation is to use it.

4) Association is the process, after authentication, that makes you real access to the network. It is similar to plugging into a wired network. 802.11 forbid associating with more than one access point.

5)The Reassociaton procedure is used when a station moves in network with many access points. Station monitors the signal quality of associated access point and other access points in the same ESS. When station detects that other access point is a better choice, it initiates Reassociaton Procedure.

All About Wifi - Wireless Fidelity

Wi-Fi ( "wireless fidelity") is a term for certain types of wireless local area network (WLAN) that use specifications in the 802.11 family. The term Wi-Fi was created by an organization called the Wi-Fi Alliance, which oversees tests that certify product interoperability. A product that passes the alliance tests is given the label "Wi-Fi certified" (a registered trademark).

Originally, Wi-Fi certification was applicable only to products using the 802.11b standard. Today, Wi-Fi can apply to products that use any 802.11 standard. The 802.11 specifications are part of an evolving set of wireless network standards known as the 802.11 family. The particular specification under

Mobile Basics

which a Wi-Fi network operates is called the "flavor" of the network. Wi-Fi has gained acceptance in many businesses, agencies, schools, and homes as an alternative to a wired LAN. Many airports, hotels, and fast-food facilities offer public access to Wi-Fi networks. These locations are known as hot spots. Many charge a daily or hourly rate for access, but some are free. An interconnected area of hot spots and network access points is known as a hot zone.

Unless adequately protected, a Wi-Fi network can be susceptible to access by unauthorized users who use the access as a free Internet connection. The activity of locating and exploiting security-exposed wireless LANs is called war driving. An identifying iconography, called war chalking, has evolved. Any entity that has a wireless LAN should use security safeguards such as the Wired Equivalent Privacy (WEP) encryption standard, the more recent Wi-Fi Protected Access (WPA), Internet Protocol Security (IPsec), or a virtual private network (VPN).
