Troubleshooting LAN Connectivity

Last Updated: Fri, 06 May 2011 > Related Articles

Summary

Sometimes the broadband router is able to obtain a public IP address, but none of the computers can connect. Follow these steps to troubleshoot LAN connectivity.

Solution

  1. Complete a Network Reset by power cycling your system. This simply involves powering everything down, and then turning everything back on.
    Note: The order in which this is done is relevant and critical to success!
    • Turn everything off starting at the computers and moving towards the wall: computers (all) first, then the router and finally the cable modem.
    • Leave everything off for a few seconds.
    • Turn everything on. Start from the wall and move out. Power up the cable modem first and allow it to get in sync.
    • Turn on the router.
    • Turn on the primary PC and finally power up the remaining PCs.
  2. Verify the router is set up as a DHCP server.
  3. Verify that all the wireless router settings related to SSID, WEP and MAC level authentication are correct.

    If a Home Network includes a Windows XP computer using a wireless connection, DO NOT disable the SSID Broadcast feature on the router. Disabling SSID can cause a loss of wireless connectivity to Windows XP. Verify the WEP and MAC address filtering security features ARE ENABLED.
  4. Change channels on the wireless router.
  5. Attempt a hard reset.
  6. If there is still no connectivity, contact the router manufacturer.
