Client cannot browse - intermittent connectivity

Core Issue

This problem may be caused by the following issues.

  • Device not associated
  • Misconfiguration of TCP/IP
  • Routing problems on the network


If you are unable to browse, check the following areas.

  1. Verify that the device is within radio range and is associated. For more information, refer to the Interpreting the Indicator LEDs section of the Troubleshooting Guide for the client adapter.  

  2. Check your TCP/IP configuration. Ping your own IP address, then ping the access point's IP address, then finally ping the default gateway. If you cannot ping the access point, verify the association. If you are able to ping the above but unable to browse the internet using a web browser then the problem is most likely caused by something in the upper layers, like dns. More information can be found at Internetworking Troubleshooting Handbook.   

  3. If the configuration is valid, then check the routing capabilities on the network.
