Enable / Disable an Enterprise Laptop's Wi-Fi
Wi-Fi, short for Wireless Fidelity, is networking technology that allows you to connect to the Internet. If you have a wireless-enabled Latitude computer you can connect to the Internet when in range of an access point called a hotspot.
When not in use your Latitude's wireless card should be disabled. By disabling Wi-Fi, you will receive two benefits:
Start-up times will be much faster.
If the wireless card is ON and you are out of the office (not connected to your normal, wired connection), the laptop will try to use the Wi-Fi network during the login process to run the various start-up scripts, etc. It will eventually time-out (fail). By having the wireless card turned OFF, the start-up process will be much faster.
Computer will not continually search for a wireless network (and waste battery life).
If you are in the office (connected to your normal, wired connection) or in a location where there is no wireless hotspot, you don't need to have the computer waste processing power by looking and looking for a wireless hotspot. By disabling Wi-Fi, you will gain a little more power for your other tasks. In addition, you will maximize your battery operating time by disabling wireless activity.
NOTE: After your Latitude has started up completely, you can ENABLE the wireless card and connect to a wireless hotspot. For example, a wireless router at your home or at a local coffee shop. If you have connected to this hotspot previously, the wireless card should connect automatically for you.
NOTE: Once you have the wireless card enabled, before you shut down the computer, you should again DISABLE the card. The computer will then be ready for the next time you turn it on with wireless turned off.
Enable / Disable with Hardware Switch
The more recent Latitude models have a wireless switch to enable or disable wireless network devices and the
Wi-Fi Catcher Network Locator.
Dell Latitude E6420 and E6520 Series
These laptops have a small switch on the RIGHT side of the keyboard. The switch is toward the front of the laptop. The Wi-Fi Catcher™ icon will is above the keyboard. You will see a lit radio tower if the wireless switch is enable

Wi-Fi provides wireless Internet access over distances of up to 100 meters (00 feet).

To use Wi-Fi on your phone, you need access to a wireless access point or "hotspot". The availability
and range of the Wi-Fi signal depends on the number, infrastructure, and other objects
through which the signal passes.

Turning Wi-Fi on and connecting to a wireless network
From the Home screen, press MENU, and then tap Settings > Wireless & networks.
Select the Wi-Fi check box to turn Wi-Fi on. The phone then scans for available wireless
networks.

Tap Wi-Fi settings. The network names and security settings of detected Wi-Fi networks
are displayed in the Wi-Fi networks section.
If the wireless network you want to connect to is not in the list of detected networks,
scroll down the screen, and then tap Add Wi-Fi network. Enter the wireless network
settings, and then tap Save.

Tap the Wi-Fi network you want to connect to.
If you selected an open network, you will be automatically connected to the network.
If you selected a network that is secured with WEP, enter the key and then tap
Connect.

Depending on the network type and its security settings, you may also need to enter more information
or choose a security certificate.
When your phone is connected to a wireless network, the Wi-Fi icon appears in the
status bar and tells you the approximate signal strength (number of bands that light up).
The next time your phone connects to a previously accessed secured wireless network, you
will not be prompted to enter the key or other security information again, unless you reset
your phone to its factory default settings.

If you are using internet on PC/Laptop and you want to increase the speed of internet. Then below are some tips to speed up internet:-

- Re-install the Adapter.
- Update Wi-Fi Drivers.
- Optimize Internet (Use reliable program for it like Reginout.)
- Disable Global Auto-Tuning Feature.
- Uninstall Remote Differential Compression API Support.
- Clear DNS.
- Upgrade your Wi-Fi's Antenna (If needed)

Title: How to install OS

Just load OS CD in to your dvd driver and restart it

• Press any key..... when show this message
• And do it as given instruction

Installation

*Note to wi-fi users. I recommend you use a wired connection for everything until XP is completely setup. Disable the wi-fi connection on first boot or as soon as you get the drivers installed. To disable the connection Open your Network Connection Properties, go to Start > Run > type control ncpa.cpl exactly as you see here > right-click on the wi-fi connection and choose disable.

Start your computer and insert the XP disk. If your computer supports booting from a CD you may need to change the bios startup options. The key you press to access the bios may differ depending on the make of your computer. Most use the DELETE key, if not then it will be one of the FUNCTION keys (F1, F2, etc.) Save changes and exit. If your computer does not support booting from CD then insert the first Windows XP floppy disk.

As the system boots you will see a message at the bottom of the screen:

"Press F6 if you need to install a 3rd party SCSI or RAID driver." If you do, follow the instructions.

OR

Click on the following link-

http://tweakhound.com/xp/installxp/installXP1.htm

To log into your WRT54G, open a Web browser on a computer that's connected to your router and go to http://192.168.1.1/ - the default username is admin and the default password is blank (leave the field empty).

----

In the Setup tab, Basic Setup subtab:

DHCP Server should be set to Enable.

If you had to change this setting, be sure to click the Save Settings button.

----

In the Wireless tab, Basic Wireless Settings subtab:

The first data item is Wireless Network Mode. For reasonable performance, this should be set to either Mixed or G-Only. You should be able to connect your NOOK even if it's set to B-Only, but that would be a very unusual setting and would give slower networking.

Wireless Network Name (SSID) is the name of your Wi-Fi network. If it still says 'linksys', change it to something different-but be aware that you'll need to reconnect all of your current Wi-Fi devices using the new SSID. That's a pain in the behind, but using the default SSID will cause you lots of connection grief if someone else installs a Wi-Fi router with the default SSID, because your devices won't be able to tell them apart. Write down your SSID, being careful to distinguish capital letters from small letters, so you'll know what it is.

Wireless SSID Broadcast should be set to Enable. Otherwise, your NOOK won't see your network. You could type in your SSID, but that's a pain in the behind that you don't need. There's no reason not to enable SSID broadcast.

If you had to make any changes to these settings, be sure to click the Save Settings button.

----

In the Wireless tab, Wireless Security subtab:

Security Mode: write down which of the choices is selected:

• Disable
• WPA Pre-Shared Key
• WPA RADIUS
• RADIUS
• WEP

I say to write this down just in case you run into more trouble and need to ask someone for help.

If 'Disable' is selected: you have no security on your Wi-Fi. Anyone can use your Internet connection, and anyone can listen in if they're in range. If you send unencrypted passwords, email, etc., they could see what you send. Most public Wi-Fi systems (McDonald's, Starbucks, B&N, etc.) have no security.

If either 'RADIUS' choice is selected: these settings are used for large organizations with stringent security requirements and a dedicated authentication server. Your NOOK cannot connect if either of these settings is used. You almost certainly don't want to be using either of these for a home system.

If the 'WPA Pre-Shared Key' choice is selected: WPA offers good security for Wi-Fi and is the best of these choices for home use.

• WPA Algorithms should be set to TKIP. This is the normal setting for WPA. I don't know if your NOOK will connect if you set it to AES, which is normally used with WPA2 rather than WPA.
• WPA Shared Key is the access key for your network. Write it down, being careful to distinguish capital letters and small letters. You'll definitely need this key in order to connect your NOOK or any other Wi-Fi device to your router. Don't change this unless you're prepared to go back and reconnect your other Wi-Fi devices. Unfortunately, there are some punctuation marks that you can't enter on the NOOK keyboard, and if your WPA passphrase contains one of those you may need to change the passphrase in order to connect your NOOK.

If 'WEP' is selected: the WEP security system is a weak system, easily cracked by knowledgeable hackers. However, many older wireless devices and some of the cheapest new wireless devices can't handle anything better than WEP. This isn't a good situation, but you work with what you've got.

• Default Transmit Key should be set to 1.
• Passphrase is not important. It is not your network's access key. Ignore it.
• Key 1 is the access key for your network. Write it down. It will be either 10 or 26 characters, containing only the numbers 0-9 and the letters A-F. You will definitely need this key in order to connect your NOOK or any other Wi-Fi device to your router. There's no reason to change this, and if you do change it you'll have to go back and reconnect your other Wi-Fi devices.

If you had to make any changes to these settings, be sure to click the Save Settings button. Any changes in this section will also require that your existing Wi-Fi devices be reconnected.

----

In the Wireless tab, Wireless MAC Filter subtab:

• Wireless MAC Filter should be set to Disable. If it's enabled and set to Permit only mode, only the devices listed on the MAC Filter List can use your Wi-Fi. If your NOOK isn't in the list, you can't connect your NOOK. Bad ju-ju, huh?

If you had to change this setting, be sure to click the Save Settings button. Changing this should not require your current Wi-Fi devices to reconnect.

It's possible to add your NOOK to the MAC Filtering list and then turn MAC Filtering back on. But that's beyond the scope of this posting. I will, however, mention that your NOOK's MAC address is listed in its Settings screen-on page 2 if it's a NOOK 3G.

----

In the Wireless tab, Advanced Wireless Settings subtab:

• Authentication Type should be set to Auto. Do not set it to 'Shared Key'; this won't work with NOOK. Auto should work with any WEP-capable devices. If it's set to 'Shared Key', change it to 'Auto'-this shouldn't affect any of your current Wi-Fi devices.

If you had to change this setting, be sure to click the Save Settings button. Changing this should not require your current Wi-Fi devices to reconnect.

----

You should now be able to connect your NOOK using the SSID and the access key that you wrote down.

Resolution If you know there is a nearby Wi-Fi network, but you are unable to locate it on the Settings > Wi-Fi screen:

• Move closer to the Wi-Fi router or hotspot.
• If you are using a personal Wi-Fi network, verify the Wi-Fi router is connected to power and turned on.
• Wi-Fi networks configured as "closed" or "private" do not broadcast the network name to Wi-Fi devices.
  • Join a "closed" or "private" network by tapping Settings > Wi-Fi > Other and entering the Wi-Fi network name, security, and password.

After joining a Wi-Fi network, if you notice the signal strength is low or intermittent

• Move closer to the Wi-Fi router or hotspot.
• Check for any sources of potential interference.
• Remove any cases or attachments on your device that could interfere with a Wi-Fi signal.

If you are unable to access the Internet while connected

• If you are using a commercial Wi-Fi network that requires a special login or subscription, see this article for more information.
• If you are in a location with multiple Wi-Fi networks, verify that you are selecting the correct network.
• Verify that the Wi-Fi network settings are correct:
  • Tap Settings > Wi-Fi.
  • Locate the Wi-Fi network you are currently using and tap
    

• You can configure network-specific settings, including IP address, DNS, and Search Domain settings.
• Use "Forget this Network" to reset settings for this particular Wi-Fi network, including the password. This is also useful if you identify a network issue and want to prevent the device from automatically using this network in the future.
• Use "Renew Lease" to acquire new IP address, DNS, and Search Domain information from the Wi-Fi network.
• Note: If the Wi-Fi network uses MAC address filtering, you will need to add the MAC address to the access list for the Wi-Fi router. The MAC address for your device is listed as the Wi-Fi Address in Settings > General > About.

If you are still unable to join a Wi-Fi network, or are unable to access the Internet while connected, try the following

• Restart the device
  • Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the power button to turn it back on.
• Reset network settings by selecting Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings, including passwords, VPN, and APN settings.
• iPhone only: If you continue to experience issues, consider turning off Wi-Fi and using the cellular data connection instead of Wi-Fi.

Additional Information If using a Wi-Fi router at home, refer to your user manual/documentation to assist you with some of these suggestions.

• Check the manufacturer's website for your Wi-Fi router for firmware or software updates.
• Verify the Wi-Fi router can broadcast an 802.11b/g signal. If using a 802.11n Wi-Fi router, consult the manual/documentation for how to configure the Wi-Fi router for 802.11b/g compatibility.
• If you are using multiple WEP keys on your Wi-Fi router, try configuring your Wi-Fi router to use only a single WEP key.
• Try or resetting (or turning off and then on again) your Wi-Fi router. Note: If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
• Disable wireless encryption or security on the Wi-Fi router to rule out encryption issues. If this resolves the issue, try using a different encryption or security protocol.

hi dear

try this

1. Before you attempt to use any Wi-Fi network, find out what the SSID, Channel, Mode and WEP key are. Some Wi-Fi locations do not require a WEP key. Many Wi-Fi providers have this information on their web site or when you purchase access you will be provided the information.
2. Ensure you have a firewall program installed and running. This will protect your data.
3. Start up your laptop and once booted, look for the Wi-Fi network icon in the bottom right of the screen.
4. Click on the Wifi Connection icon on bottom right of screen and you should see a window that indicates connection, strength and duration. Click on the Properties tab.




5. The next window will show the type of networking card installed. Click on the Wireless Networks tab.




6. Once the Wireless Network Connection Properties window is open you will have two options depending on how you set up your laptop.
• If you do not see any networks listed in Preferred or Available networks, you will have to manually add the SSID. Click on Add. You will have to enter the SSID and WEP key (if required). Click OK and you should then see the network you just added in the Available networks box.




• If you see the correct SSID showing in the Available Networks, then you need to click on Configure in order to enter the WEP key if that is required.




7. In the next window, enter the SSID for the Wi-Fi network you want to access. Make sure you do not have CAPS lock or NUM lock while entering the information. If a network key is required, click on "Data Encryption and then enter the Network key you have been provided with. Again make sure you do not have CAPS or NUM lock on. Click OK when entered. If you have entered the key incorrectly a message will pop up and you will need to re-enter the key.




8. Next go to Start - and where it says Connect To click on that and you should see choices like in the graphic below. Click on Wireless Network Connection and it should work.

There are occasions when the connection doesn't work, in these cases check your firewall software and make sure it allows you to connect to the Wi-Fi network. To check this, disable your firewall software and check the connection again. If you can connect with the firewall program disabled, you change your settings. If your firewall program is not the problem check the SSID and WEP key information that you entered. Both of these are case sensitive. If you had obtained SSID information from the Internet, check with someone in the establishment to see if the SSID has been changed.

oke post in me back

i hope this usefull for you


thanks
