I have a Cisco 1841 router with the WIFI A/B/G module. I used Cisco Configuration Professional to configure an SSID which uses WPA. After I have created this setup and delivered it to the running config, the SYS ACT light starts rapidly blinking non-stop.
If I remove the SSID setup then the SYS ACT light goes out. Is this normal or is there something wrong? I am still testing this out before I deploy it on my home network. I don't have any other services running on it yet. I did reboot the router after setting up the SSID.
The router is using 64 MB flash with 384 MB ram. IOS version is 12.4(15)T17 and IOS image is c1841-adventerprisek9-mz.1
WiFi module is HWIC-AP-AG-A and is in Slot 0. Attached is a screenshot with the setup.
