My wireless is not working,on,we have wlan,not secured,

Here are some essential step that you have to follow.
Connecting to a WLAN
To connect to the WLAN, follow these steps:
1. Be sure that the WLAN device is on (the wireless light is white). If the wireless light is amber, press
the wireless action key (f12).
2. Click the network icon in the notification area, at the far right of the taskbar.
3. Select your WLAN from the list.
4. Click Connect.
If the network is a security-enabled WLAN, you are prompted to enter a network security key, which
is a security code. Enter the code, and then click OK to complete the connection.
NOTE: If no WLANs are listed, you are out of range of a wireless router or access point.
NOTE: If you do not see the network you want to connect to, click Open Network and Sharing
Center, and then click Set up a new connection or network. A list of options is displayed. You
can choose to manually search for and connect to a network or to create a new network connection.
After the connection is made, place the mouse pointer over the network icon in the notification area, at
the far right of the taskbar, to verify the name and status of the connection.

Do you get an error that says something such as "Unable to validate identity"? You can definitely fix this issue by logging into the modem and changing the security to WEP. If not WEP you can try no security. I know that no security will work but its trial and error to find out which security type will work with the Dell wireless.

Security Code is configued in Wireless Router itself.

Please open your Wireless router Admin Panel in Internet Explorer. Please follow this steps.

1. Open Internet Explorer and type : http://192.168.x.x and press enter (x is router IP. Generally its 1.1 or 0.1)
2. Go to Wireless Security Tab and look there for Security code.

Now type that Security code in your Ps3 .

You find all details regarding to access router in internet explorer from Product Manual. (you can download product manual from Manufacturer site)

Secured Wireless is better than a unsecured one. Configuring a secured wireless network easy.
· First Check it the Wireless is turned on in the modem.
You must see the wireless light glow on.
Wireless LAN (WLAN) should be Enabled before configuring the wireless network
· To make sure, if the WLAN is enabled you can check the WLAN light glow.
· If it is off, then you can be sure that WLAN is disabled.

SonicWALL Wireless Configuration Wizard To access SonicWALL’s Wireless Configuration Wizard, log on to the SonicWALL router, then click the Wireless button found within the left navigation bar of SonicWALL’s Web-based management interface. The Wireless Status page will be displayed. Click the Wireless Wizard button that appears toward the top-right of the screen.
The SonicWALL Wireless Configuration Wizard will appear. Click the Next button to proceed with the wireless administration utility.
The wizard’s first step will appear as seen in Figure A. Step one addresses wireless local area network (WLAN) network settings. You must specify the WLAN IP address and subnet mask before continuing. In addition, a checkbox is provided for enabling Windows networking support between the wired local area network and the WLAN. Be sure to check the box to enable communication between the LAN and WLAN. Then, click Next.

Step two requires setting the Service Set ID (SSID), radio mode, country code and channel. The SonicWALL wizard provides a blank field for specifying the SSID. The default SSID is sonicwall. Consider changing the SSID to a value that reveals nothing about the organization or office in which it is deployed. I typically deploy SSIDs as HomeNetwork and BusinessNetwork, as doing so provides potential hackers with less information about a network (particularly in more heavily populated areas such as apartments and office parks).
On most SonicWALL routers, including the popular TZ 170 wireless model, three radio modes are available: 2.4GHz 802.11 b, 2.4GHz 802.11g or 2.4GHz 802.11g and b Mixed mode. Using the provided drop-down menu, select the mode you wish to use within your organization.

The last item to configure within Step 2: WLAN 802.11b/g Settings is the channel. Channels one through 11 are available options. Or, AutoChannel is an alternative choice and, in fact, the default. Choosing AutoChannel allows the wireless network equipment to automatically negotiate the best channel settings. Once the channel is specified, clicking Next continues to the next step.
Step 3: WLAN Security Settings enables configuring one of three security modes for the
SonicWALL wireless router. The three security mode choices are:

• WiFiSec VPN Security – The default selection, WiFiSec VPN Security creates an IPSec-powered VPN over which the wireless traffic travels.
• WEP + Stealth Mode – Utilizes Wired Equivalent Protection (WEP) to secure wireless communications.
• Connectivity – Implements wireless communications featuring no encryption or access controls.

When selecting WiFiSec VPN Security and clicking Next, the Step 4: WiFiSec – VPN Client User Authentication page appears. This step helps create a user name and password for a new user with VPN client access privileges. The WLAN WiFiSec security setting will enable the SoniCWALL Group VPN feature. If you wish to edit user privileges, you can log on to the SonicWALL router’s Web-based administrative interface and edit user permissions by clicking Users | Settings.
After a user name and password are supplied, click Next to proceed to the wizard’s fifth step. The Step 5: Wireless Guest Services screen allows you to enable guest wireless access while also specifying the guest account name, password and account and session lifetimes.
Once these values are supplied, click Next to view a Wireless Configuration Summary. Clicking Apply prompts the SonicWALL Configuration Wizard to apply the settings and configuration parameters you’ve entered into the wizard. When the wizard completes, a confirmation page should then appear (with a Finish button being the only available option).

Did you input the WEP key? I will assume you are using Windows XP. So go to control panel, network connections and then go to the wireless connection and then select view wireless connections double click on the one with the highest strength, which should be your 2wire. When it asks for the network security key type in the numbers that are located on the sticker on the bottom of your router between the [########] brackets.

Check with this tip.
Check if router is working on Net using a Lan cable to connect your PCs and check if you can browse from PC..
If Internet OK check if radio is enabled in your Belkin router.
Then check if your SSID broadcast is enabled in your router.
Check if Router and PCI Wlan adapter are on same WLAN standard A,B, G, or N and disable every security protocol (WEP or WPA)
Define a new SSID name and check if you see your Wlan on PC.
Restore your security as soon as connection established.

1) Verify if Wi-Fi WLAN interface of your notebook is OK.
1a) Check whether HW switch is ON and the wireless system service is running.
1b) Switch on the WLAN Access Point (router) SSID broadcasting.
1c) Scan WLAN networks by the notebook. Can you see your home WLAN? If not, there is HW or SW problem in your wireless adapter probably. If WLAN is visible, continue by next steps.

2) Remove all WLAN security on both sides (AP and notebook): Authentication = none/open, encrytption = none.
3) Activate DHCP server in the router and set the dynamic IP assigning on WLAN notebook interface.
4) Select your home WLAN SSID in the list and try to connect.
5) Wait and check status. Is WLAN connected? Does obtain the notebook an IP address?
6) In success case set the WLAN security.

make sure that your wireless network card works.go to the settings of your router and set: wireless network mode:802.11b(or what your car supports) wireless network name:name Wireless SSID Broadcast:enabled Security Mode:wep wep key:write something create a new connection to your laptop with the above settings
