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
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
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.

Things That Affect Wireless Router Signals 1. Many wireless routers are using the same wireless channel. Many manufacturers choose channel 6 as the default. Change to another channel. 2. Analogue video senders used to send audio and video to other TVs in the home. 3. Microwave ovens emit interference in the 2.4GHz band. 4. Wireless speakers and console controllers can cause interference with the wireless router. 5. Bluetooth devices, newer Bluetooth devices can jump to different frequencies if there is a connection problem. 6. Power cables located near the wireless router can cause dropouts and speed reduction. 7. Fish tanks will cause massive Wi-Fi shadow on the other side of the tank from the wireless router. 8. Depending upon the location of large mirrors will reflect wireless signal away your computer. 9. Building materials will block wireless signals such as plasterboards with metal foil, reinforced concrete walls and floors. Also objects near the wireless router such as metal filing cabinets and other electrical appliances. 10. Blinking Christmas lights can reduce Wi-Fi performance by 25% when it is close to the wireless router.
Not only does Wi-Fi have to be on, but it has to be connected to a wireless access point (sometimes called a wireless router), and the wireless access point has to be properly connected to the internet.If the wireless access point/router has empty ports on it, plug your computer into one of those ports, and see if you can connect to ther internet then. If you can, the problem is somewhere between the wireless access point/router and the computer. Could be the transmitter part of the wireless router, could be the wireless network adapter on your computer, or could be the driver that runs the wireless adapter on the computer. If you cannot access the internet when you plug into the wireless ap/router, then you need to go one step "upstream." This would likely be the cable modem or DSL modem. Plug directly into that with your computer, and reboot both the modem and the computer (just unplug the power from the modem and then plug it back in to reboot the modem). If you can connect to the internet then, the problem is the wireless router/ap. If you cannot connect to the internet then, contact your ISP.
Wireless local area network is a local area network that uses high frequency radio signals to transmit and receive data over distances of a few hundred feet, uses ethernet protocol.
In simple word allow you to surf internet without any internet cable connection, Wi-Fi enabled device such as a personal computer, video game console, smartphone or digital audio player can connect to the Internet when within range of a wireless network connected to the Internet. The coverage of one or more (interconnected) access points called hotspots, can comprise an area as small as a few rooms or as large as many square miles. Coverage in the larger area may depend on a group of access points with overlapping coverage.
In addition to private use in homes and offices, Wi-Fi can provide public access at Wi-Fi hotspots provided either free-of-charge or to subscribers to various commercial services. Organizations and businesses - such as those running airports, hotels and restaurants - often provide free-use hotspots to attract or assist clients. Enthusiasts or authorities who wish to provide services or even to promote business in selected areas sometimes provide free Wi-Fi access.
You can boost the signal range of a WiFi computer network in several ways:
reposition your router
(or access point) to avoid obstructions and radio interference. Both
reduce the range of WiFi network equipment. Common sources of
interference in residences include brick or plaster walls, microwave
ovens, and cordless phones. Additionally, consider changing the WiFi channel number on your equipment to avoid interference.
add another access point (or router). Large residences
typically require no more than two APs, whereas businesses may employ
dozens of APs. In a home, this option requires connecting your primary
wireless router (access point) to the second one with Ethernet cable;
home wireless routers and/or APs don't normally communicate with each
add a bi-directional WiFi signal amplifier to wireless
devices as needed. A WiFi signal amplifier (sometimes called "signal
booster") attaches to a router, access point or Wi-Fi client at the
place where the antenna connects. Bi-directional antennas amplify the
wireless signal in both transmit and receive directions. These should
be used as WiFi transmissions are two-way radio communications.
add a WiFi repeater. A wireless repeater
is a stand-alone unit positioned within range of a wireless router
(access point). Repeaters (sometimes called "range expanders") serve as
a two-way relay station for WiFi signals. Clients too far away from the
original router / AP can instead associate with the WLAN through the
First, try changing the channel your access point (AP) is using. Maybe there is some interference with another AP or with an electronic appliance such as a wireless phone. Try all available channel. While changing your channel number, make sure that the wi-fi power of your access point is set to the maximum available (100%).
Second, make sure that there is as less metal as possible around the AP, for example if the AP is sitting in a metal book case or on a metal shelf.
Third, some appartment buildings, expecially old ones, have very thick walls made of concrete or brick. This is a nightmare for wi-fi. Try bringing the AP to a more central point in your appartment, if possible (I know this may be complicated).
