A wireless client device cannot ping an Access Point or bridge due to an incorrect IP assignment

Resolution

If you cannot ping the Access Point (AP) or the bridge, check the IP addresses assigned to the AP, bridge, and client device. They should be in the same subnet.

For example, if the AP's IP address is 10.12.60.5 with a mask of 255.255.255.0, then the client device's IP address should be similar to 10.12.60.X with mask of 255.255.255.0.

The AP and the bridge are Layer 2 devices. If you need two or more networks, a router should be on the wired network.

Note: When you connect the AP to the wired LAN, the AP links to the network using a Bridge Virtual Interface (BVI) that it creates automatically. Instead of tracking separate IP addresses for the AP's Ethernet and radio ports, the network uses the BVI. When you assign an IP address to the AP using the CLI, you must assign the address to the BVI.

For more information on IP addressing and the design of subnets, refer to the IP subnet calculation and design tool. For information on configuring IP addresses on AP read Obtaining and Assigning an IP Address .

For assistance with general connectivity problems with your wireless LAN devices, refer to Troubleshoot Common Problems with Wireless Bridged Networks.
