Basic troubleshooting steps for Internet Connectivity

Below specified steps can be used if you get the following error message:

  • No internet connection
  • Unable to go online
  • No network found
  • Issues with Network adapter


1.     Verify that the network adapter is being seen by the operating system:

 
Check Microsoft Windows Device Manager and look for an icon that appears as Network Adapters and see if the network card listed in Mini-PCI information table is installed:

1.     Right-click the My Computer icon and select Properties.

2.     Click the Hardware tab and press the Device Manager button. The network card should appear under Network Adapters.
Note: If the card has a exclamation mark over a yellow background, then this is an indication that the card is experiencing a problem. Go to Driver download step 5.

2.     Verify that the radio is enabled:

·          It is possible to disable the transmitter of the wireless card without Device Manager showing any problems. Most wireless cards will put an icon in the system tray (the line of icons in the lower right corner of your screen). Right click this icon and it may have a menu option to enable/turn on the wireless radio.

Use the function keys: Press Fn+F2 (This will vary for every brand and model, please check the product manual).

3.     Check the SSID (the Network name of the wireless network you are trying to connect to) and security settings:

Note: The SSID and WEP key are case sensitive.

·         The connection will fail if the SSID is incorrect.

·         The most common security setting is the use of a WEP key. This involves using a 5 digit alphanumeric key for 64bit encryption or 13 digit alphanumeric key for 128bit encryption. Some systems will only allow a hexadecimal (0-9, A-F) key of either 10 (64bit) or 26 (128bit) characters. It may be necessary to convert your alphanumeric key to a hexadecimal one in order to connect properly.

Note: It may also be necessary to temporarily disable the security features in order to check for basic connectivity.

4.     Ping the loopback address:

1.     Click Start, select Programs, select Accessories, and then click Command Prompt.

2.     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

5.     Verify that the hardware is functioning using diagnostics.

 

·          Run diagnostics on the wireless card.
