To troubleshoot clients connected to the SSID but experiencing no Internet access, follow these steps:

  1. Ping check:
  • Confirm and list the IP address of AP, Switches, Gateway that wireless clients are connected.
  • Use client to ping checks to identify where the point-of-failure is. Having the wireless client ping the following devices: AP, Switch, Gateway IP address and 8.8.8.8 (Internet).
  • Inspect network setting of device that wireless clients cannot successfully ping.

2. DNS check:

  • Use "nslookup" (or similar tools) on wireless clients to check if DNS server can resolve domain name of website you cannot access.
  • If domain name could not be resolved, manually change the wireless client's DNS server to 8.8.8.8 (Google DNS)
