Hi there

I think up to now you've been using someone else's Internet service, by picking up the signal wirelessly. You need your own Internet Service. You now connect your access point in the way the Internet Service Provider guide you. It is a different set up with cable (they provide a modem) or with BT (connection through your phone line).

Hi, you need to connect to the A.P. by wire, using it default IP, and select the current country where the A.P. is going to be deployed. If you don't do this, your A.P. wont turn antennas ON because the firmware won't know what the frequency standards it should use, avoyd interference on other products!!

Verify that TCP/IP (or other appropriate protocol) is properly installed.

  1. Open Control Panel and open Network Connections or Network and Sharing Center, then click Change adapter settings. The wireless card should be present as Wireless Network Connection.
  2. Right-click the appropriate Wireless Network Connection and select Properties. In the Properties window, make sure that the Internet Protocol (TCP/IP) or Internet Protocol Version (TCP/IPv4) is installed.
  3. If TCP/IP is not installed, click Install, click Protocol, and then click TCP/IP.
  4. Once installed make sure that Obtain an IP address automatically, and Obtain DNS server address automatically are checked (if using DHCP). To verify this, highlight the TCP/IP protocol, and select Properties.
Note: Only use a Static IP Address if your network/Service Provider requires one.

8.Verify the TCP/IP address.

  1. Click Startwindows%20start%20button.png, select All Programs, select Accessories, and then click Command Prompt.
  2. Type the command, ipconfig. This will list the IP address for the local machine.
  3. If this returns a 169.x.x.x or 0.0.0.0 address, then type the following commands;
    ipconfig /release and then
    ipconfig /renew.

    You should then receive a TCP/IP address appropriate to your network, along with a Default Gateway address.
  4. Try to communicate with it by typing this command ping x.x.x.x where x.x.x.x is the IP address of the Default Gateway. (i.e. ping 192.168.1.1)
  5. If this does not give a reply (see the example in step 9) or you did not receive a TCP/IP address, go to the next step.
  6. If you are connecting wirelessly, but receiving an IP address, your wireless router/Access Point might need to be reset (unplug power for a minute, then plug back in), or maybe defective. Please consult your wireless router/Access Point manufacturer for further assistance.

9. Ping the loopback address.

  • Click Startwindows%20start%20button.png, select All Programs, select Accessories, and then click Command Prompt.
  • Type the command, ping 127.0.0.1. This will send a message to the internal network stack on the machine. You should see a response like this:

    Pinging 127.0.0.1 with 32 bytes of data:

    Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
    Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
    Reply from 127.0.0.1: bytes=32 time<10ms TTL=128
    Reply from 127.0.0.1: bytes=32 time<10ms TTL=128

    Ping statistics for 127.0.0.1:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
    Approximate round trip times in milliseconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms
  • If instead, you receive errors, then there maybe system corruption or malware installed preventing networking from functioning properly.
  • 10. Verify that the hardware is functioning using diagnostics.

    • Check the web site, http://support.lenovo.com. Choose Download Drivers and Software and enter your particular system. Then under Diagnostic choose the download for your system. If diagnostics fail, please contact warranty support for resolution.
    • Run diagnostics for third party wireless card.
      Note: If using another manufacturer's product, then consult it's documentation on how to run the diagnostics for the wireless card.

Can't ping internal page


It may be that the WAP was set-up to use a different subnet from the default.

Check the IP address that is assigned to the computer that is connected to the router and substitute the first 3 octets (192.168.10 is the default) with what your computer reports. So, if your computer has an IP address of 192.168.22.32, then use 192.168.22.100 instead.

If that doesn't work, you will probably have to do a factory reset on the device to get it to use the default address.

What IP is your Internet Modem using? If they use the same IP you'll have problems.

Your PC is connected wirelessly or directly via ethernet cable?

If you hare directly connected and you have your router set to enable DHCP, you should get an IP address. I assume you are familiar with networking enough since you know how to open command prompt and ping your router. Make sure that you get an ip (ipconfig). If not, make sure your cable is good and connected solidly and ensure DHCP is enabled on your router. If you are using static, just make sure the IP you assign to your desktop is in the same subnet. If you have a 255.255.255.0 subnet you can have 254 hosts on your network and they all have to be 192.168.1.X where X will change.

I can't log in to configure my router. I tried loging in using 192.168.1.1 but its not working an I don't know why. Help please


You may need to double check if the router is giving the correct IP address. You can this by doing the following:

1. Go to Control Panel.
2. Got to Network Connections
3. Right click on the the connection that you are using to connect to the router, wired or wireless. Then go to Status.
4. Go to the Support tab. Check the IP address and the Default Gateway, it's the Default Gateway that will tell what is the correct router IP address.

After you verify the correct IP address, you test if your computer is still communicating with the router. To do this, do the following:

1. Click Start go to Run and type "cmd" and then hit return.
2. In the command prompt, type this command "ping 192.168.1.1" or ping whatever IP address you will see in the support tab for Default Gateway.

You should get four replies if your computer is communicating with the router. If you not make sure that you disable the firewall/s in your computer. You can also use a different computer.

Chapter 1: Connecting the Wireless-G Broadband Router
Hardware Installation
1. Locate an optimum location for the Broadband Router. The best place for the Broadband Router is usually at
the center of your wireless network, with line of sight to all of your mobile stations.
2. Fix the direction of the antenna. Try to place it in a position that will best cover your wireless network.
Normally, the higher you place the antenna, the better the performance will be. The antenna's position
enhances the receiving sensitivity.
3. Connect a standard Ethernet network cable to the Broadband Router’s Internet port. Then, connect the other
end of the Ethernet cable to your Cable or DSL Broadband modem.
4. Connect your network PCs or Ethernet devices to one of the Broadband Router’s numbered ports with a
standard Ethernet network cable.
5. Connect the AC Power Adapter to the Broadband Router's Power Socket and the other end into an electrical
outlet. Only use the power adapter supplied with the Broadband Router. Use of a different adapter may result
in product damage.

Chapter 2: Configuring the PCs
Overview
The instructions in this chapter will help you configure each of your computers to be able to communicate with
the Router.
To do this, you need to configure your PC’s network settings to obtain an IP (or TCP/IP) address automatically, so
your PC can function as a DHCP client. Computers use IP addresses to communicate with the Router and each
other across a network, such as the Internet.
First, find out which Windows operating system your computer is running. You can find out by clicking the Start
button. Read the side panel of the Start menu to find out which operating system your PC is running.
You may need to do this for each computer you are connecting to the Router.
The next few pages tell you, step by step, how to configure your network settings based on the type of Windows
operating system you are using. Make sure that an Ethernet or wireless adapter (also known as a network
adapter) has been successfully installed in each PC you will configure.
Configuring Windows 98 and Millennium PCs
1. Click the Start button. Select Settings and click the Control Panel icon. Double-click the Network icon.
2. On the Configuration tab, select the TCP/IP line for the applicable Ethernet adapter.
Do not choose a TCP/IP entry whose name mentions DUN, PPPoE, VPN, or AOL. If the word TCP/IP appears by
itself, select that line. Click the Properties button.
3. Click the IP Address tab. Select Obtain an IP address automatically.
4. Now click the Gateway tab, and verify that the Installed Gateway field is blank. Click the OK button.
5. Click the OK button again. Windows may ask you for the original Windows installation disk or additional files.
Check for the files at c:\windows\options\cabs, or insert your Windows CD-ROM into your CD-ROM drive and
check the correct file location, e.g., D:\win98, D:\win9x, etc. (if “D” is the letter of your CD-ROM drive).
6. Windows may ask you to restart your PC. Click the Yes button. If Windows does not ask you to restart, restart
your computer anyway.
Configuring Windows 2000 PCs
1. Click the Start button. Select Settings and click the Control Panel icon. Double-click the Network and Dialup
Connections icon.
2. Select the Local Area Connection icon for the applicable Ethernet adapter (usually it is the first Local Area
Connection listed). Double-click the Local Area Connection. Click the Properties button.
3. Make sure the box next to Internet Protocol (TCP/IP) is checked. Highlight Internet Protocol (TCP/IP), and click
the Properties button.
4. Select Obtain an IP address automatically. Once the new window appears, click the OK button. Click the
OK button again to complete the PC configuration.
5. Restart your computer.
Configuring Windows XP PCs
The following instructions assume you are running Windows XP with the default interface. If you are using the
Classic interface (where the icons and menus look like previous Windows versions), please follow the
instructions for Windows 2000.
1. Click the Start button and then the Control Panel icon. Click the Network and Internet Connections icon.
Then click the Network Connections icon.
2. Select the Local Area Connection icon for the applicable Ethernet adapter (usually it is the first Local Area
Connection listed). Double-click the Local Area Connection. Click the Properties button.
3. Make sure the box next to Internet Protocol (TCP/IP) is checked. Highlight Internet Protocol (TCP/IP), and
click the Properties button.
4. Select Obtain an IP address automatically.
Once the new window appears, click the OK
button. Click the OK button again to complete the PC configuration.

Netgear WG602 wireless router,


Hi, Assuming that the WG602 is fully operational, when you did a hard reset, the router reverted to its original factory setting as you posted. The default pre-configuration: act as a DHCP client; if the WG602 does not find a DHCP server on the Ethernet LAN, it defaults to this IP configuration: DHCP Client - Enable IP Address ? 192.168.0.227 IP Subnet Mask ? 255.255.255.0 Gateway ? 0.0.0.0 Your PC need to be connected via a LAN cable to one of the Ethernet ports of the AP/Router to be able to configure it again to your desired network settings. Further it is necessary likewise to manually configure the connected PC's networking configuration to match the router. Manually configure your PC's IP Address to 192.168.0.228, Subnet Mask ? 255.255.255.0, Gateway - 192.168.0.227. You can now try configuring the router through its web interface (192.168.0.227). This is better explained in the user's manual available at the Netgear site ( Hope this be of some help/idea. Post back should you need additional information. Good luck and kind regards.

Loses connectivity


Hi, a couple of ideas: 1. maybe out of range or too many obstruction, how far is the client from the AP or are there any objects in between. it's gotta be line of sight; 2. with 200mW power output and 5dBi external antenna, should be adequate, if not maybe slightly directional performance (no longer perfect omni). try rotating the device and more or less guesstimate max signal at a particular orientation (pointed towards the client). Netstumbler would be good enough for signal strength; 3. consider the optional integrated 9dBi patch antenna; 4. for the client having a hard time with the AP, manually enter the TCP/IP settings and not auto obtain. numbers should of course match AP settings except for the last digit(s) of the IP add; 5. try moving the client away from any RFI sources like cordless/wireless phones, microwave ovens and others; 6. at one time, signal strength to a client improved by moving the AP a couple of feet away from the original installation point. of course if your unit is mast mounted, then you have to move the mast as well or put up a new one. Hope this works for you. Good luck and pls post again how things turn up.
