Click the "Start" button and select the "Control Panel" from the right column to open it.
Select the "Network and Internet" section of the Control Panel.
Click "Network Connections" if using Windows XP to view the available network icons.
Or, click "Network and Sharing Center" if using Windows 7 or Vista and select "Change adapter settings."


Right-click your network connection icon which displays either the yellow triangle or red "x" indicating limited or no connectivity.
Select "Properties."
Click on "TCP/IP" to select and highlight it. Click "Properties."

Manually Renew IP Address
Click the "Start" button and choose "Run" from the list.

When renewing your IP address, Windows automatically attempts to connect to the network.
Powercycle Router and Modem
Turn off your computer.


Unplug both the Internet modem and wireless router's power adapter from the electrical outlet. Wait for two minutes.
Plug the Internet modem into the electrical outlet first. Wait for connectivity lights to appear.
Plug the wireless router's power adapter back into the electrical outlet.
Confirm that lights appear on the router indicating that it has established a connection to the modem.


Turn on your computer.
Open "Network Connections" if your computer does not connect automatically to the network.
Select a network from the list, input the network password if one exists and click "Connect."
Open your Internet browser to test the connection.
Update Network Interface Card (NIC) Drivers

Click the "Start" button. Right-click "My Computer" or "Computer" from the Start Menu. Select "Manage." Click "Yes" if a user account control message appears.


Click on "Device Manager" from the list of System Tools.

Right-click your computer's network adapter from the list and select "Properties."
Click the "Driver" tab and select "Update Driver."
Follow the on-screen prompts to allow Windows to find and install the drivers automatically. Restart the computer when the process is finished and attempt to re-connect to the network.
Reset Internet Protocol (TCP/IP)

Click the "Start" button and select "Run."
Type "cmd" and press "Enter" to open the Command Prompt.


Type the following line into the Command Prompt and press "Enter":
netsh int ip reset resetlog.txt
Close the Command Prompt. Issuing this command tells Windows to remove and then re-install the two registry keys used by the Internet Protocol (TCP/IP) component of Windows.


Restart the computer.
Attempt to connect to the network if a connection is not established automatically.

Make sure you are completely connected to the wireless network.
Open an command prompt Type CMD in the run box on the start menu
In the command prompt window type IPCONFIG /release
Next type IPCONFIG /renew

First, make sure you are plugeed into ports1-4, not in the Uplink port. Secondly :

1. Click the Start menu button on the Windows taskbar.
   
   
2. Click Run... on this menu.
   
   
3. If the computer is holding a current IP address, type 'cmd' (without the quotes) in the text box that appears. A command prompt window appears on the screen.
   
   
4. Type 'ipconfig' (without the quotes) to view the status of the computer's IP address(es).
   
   
5. If the computer is holding a current IP address, type 'ipconfig /release' to let go of the address.
   
   
6. Type 'ipconfig /renew' to obtain a new IP address (whether or not the computer is holding a current address).

Tips:

1. If it is not necessary to view the current IP addresses on a computer, simply type 'ipconfig /release' or 'ipconfig /renew' (without the quotes) in the text box that appears in Step 3.
   
   
2. To bring a computer back onto the network after moving it to a different location, or experiencing an unexpected outage, first release, then renew the IP address. Computers on DHCP networks often (but not always) re-establish network connectivity automatically.

Disconnect your laptop wireless connection from the wireless acess connection. (Reboot your laptop if necessary). Then reconnect your laptop wireless connection, if your wireless network is a secured wireless network, your laptop will prompt for a network key ie your wireless network SSID password. Make sure the network key correctly entered ie.("Most wireless password keys are Upper or Lower case sensitive")

If the problem persist, then use the "Command Prompt"
Start ->"Run" ->Type "CMD" ->The command prompt will appear, then type ie without the quotes,
1. "ipconfig /release" -> enter
2. "ipconfig /renew" -> enter
3. "ipconfig /flushdns" -> enter

Hope it helps.

Check if the wireless works by directly connecting to the Lan port and the system. If it works, you may have to check for the Wireless Home Setup. Check if there are changes made to the Freequencies. 802.3 g usually gives max range. In case you are working at a distance which the signal wouldnt cover, the system can show network not detected. Also try to work on a Manual Address mode than DHCP and find if the network is getting detected. Check if the WNC is enabled and if working on DHCP, try do a tcp ip reset using the command from the command prompt... by using the command ipconfig /release.
and then ipconfig /renew
if the ip is renewed successfully, the wireless router is allocating the new tcp ip address and your network should work. Good luck.

unplug router for 10 seconds and plug back in. Then try. If needed, use network setup wizard.
You can also renew your pc's ip address by going to start menu, then run. Then type ipconfig/ release then type ipconfing /renew and everything should be fine.

go to Start > Run > type CMD

On Command line type:

ipconfig /release [ENTRER]

ipconfig / renew [ENTER]

exit

Any network ? No ? Reinstall drivers !!

Regards

1.) Check if you put static ip on your NIC. If not, then you are DHCP.

2.) Do some Command Line Interface at CMD.

a.) Start > Run > CMD
b.) ipconfig /all
d.) Try to release the ip by typing this command: ipconfig /release
c.) Then, renew : ipconfig /renew

try to flush your dns, by typing these:

ipconfig /flushdns

and register again your dns by typing these:

ipconfig /registerdns

If this solution does not correct your problem, try to reset your Netgear, by the way, do you put WPA on your wireless network?

Hit me back..

disconnect the adapter then restart computer -- re insert the adapter

you need to perform a few commands using the DOS command prompt ---- click Start > Run > type cmd then hit Enter

ipconfig /all --- hit <Enter> if you have an ip address starting with 169, then the next command you type is:

ipconfig /release --- should come back all 0's then next cmd

ipconfig /renew
