Why my phone is not connected to wireless

I had a similar issue. I powered off phone and removed battery for 1 minute. Restarted phone and made sure both wireless and cellular were connected. Go back to "about device" and check for update. Make sure your phone stays connected to wireless or cellular service while it updates. My phone is not an LG but this worked for me, I hope this helps.

Wi-Fi technology enables wireless Internet and network access through public and private hot spots.

These hot spots are widely located in homes, restaurants, bookstores, coffee shops and other businesses, so you can keep connected wherever you may travel.

To connect to Wi-Fi, you must have an enabled wireless adapter on your computer.

Most modern laptops and many desktops have this adapter built into the system, but many lack such capabilities.

However, a wireless adapter is easily installed via USB, which allows you to connect to available networks through Windows 7.

Enable your wireless adapter. Most laptops have a hot key labeled with a radio antenna.

Hold the "Fn" key and press this key to toggle wireless on or off.

Desktops likely have a physical antenna on the back of your computer that is typically always on. If you don't see such a hot key or antenna, you need to acquire a USB wireless adapter.

Attach the USB wireless adapter to an available USB port on your computer.

Windows 7 will automatically install the necessary drivers for most adapters.

If it does not, insert the CD that came with the USB wireless adapter into your drive and choose to install their drivers.

Restart your computer if you do not see a wireless icon in your Windows 7 notification area.

Click the wireless icon in the Windows 7 notification area and click the network name to which you want to connect.

If this is your home network, the correct network will likely be the one with the strongest signal.

Click "Connect" and enter the wireless security passphrase, if required.

Only secured networks will ask for a passphrase, but some public networks will require browser authentication instead.

Open your browser and navigate to any website.

If the hot spot requires browser authentication, your website request is redirected to an information page.

Follow the instructions on this page to get Wi-Fi.

This may entail clicking "Accept," entering a given password or entering a cell phone number.

After authentication, attempt your website again to verify accessibility.

Hope this helps

Hi,

If you have a laptop, you can see a list of available wireless networks, and then connect to one of those networks, no matter where you are. The wireless networks appear only if your computer has a wireless network adapter and driver installed and the adapter is enabled.

To view and connect to available wireless networks

1. Open Connect to a Network by clicking the network icon ( or ) in the notification area.
   

2. In the list of available wireless networks, click a network, and then click Connect.
   

   Some networks require a network security key or passphrase. To connect to one of those networks, ask your network administrator or Internet service provider (ISP) for the security key or passphrase.
   

Whenever possible, you should connect to security-enabled wireless networks. If you do connect to a network that's not secure, be aware that someone with the right tools can see everything that you do, including the websites you visit, the documents you work on, and the user names and passwords that you use

Instructions

1. • 1 Turn off your wireless and Bluetooth when they are not in use. If you leave your wireless settings on, your phone is constantly looking for a wireless connection, even if one isn't readily available. This eats up battery power. Touch "Manage Connections" from your home screen and select "Off" for wireless connection. Then turn your wireless on when you know a connection is available.
     
   • 2 Close applications when you're finished using them. Leaving applications running uses memory and battery power, especially if those applications send you frequent notifications, like Facebook. Once you're done using an application, use the Blackberry button and select "Close" at the bottom of the menu to close the app completely and avoid notifications until you open the app again.
     
   • 3 Use your applications wisely. If you're running short on battery life, it may not be a good time to run Google Maps or other applications that use a lot of battery power. In general, battery-consuming applications are those the need a constant internet or data connection and cause you to receive frequent notifications.
     
   • 4 Change your vibrate notifications so that they occur less frequently, and use audio notifications when you can. Vibration actually uses more battery life than a ring tone. While you may need to put your phone on vibrate when you need to use your phone discreetly, shortening the amount of vibration notifications you get can conserve battery life. Choose "Options" from your home screen, and then "Sounds and Ringtones." Choose "Ringtones" from the drop down menu and select the type of ringtone you want. To decrease the volume of your vibration -- and therefore the power you use -- press the volume buttons on the side of the phone when the phone is in vibrate mode.
     
   • 5 Decrease the backlight timeout, which keeps the keys on your Bold lit for a specified amount of time after you stop using them. The shorter the timeout, the less battery power you'll waste. Visit "Options" from your home screen and then choose "Screen/Keyboard." Adjust the backlight settings so you only have three to five second before timeout and the backlight shuts off. You can also use the settings to dim the backlight to use less power.
