That is normal operation.  IIRC the blink behavior is controlled by
drivers/net/wireless/iwlwifi/iwl-led.c for Intel cards.

I'm not sure if there's a way to control the LED without patching the
driver.  /proc/acpi/ibm/led allows control over most of the LEDs, but I
don't think it allows you to control the wireless one.
