This is the troubleshooting page for the Cisco Aironet 1200.

Access Points are pretty basic devices, so if the scanners fail to connect, the problem most likely lies in the scanners, not the AP. If you have ruled out all problems with the scanners, try to ping the access point from the ScanIt Parts server. If the AP pings successfully, the problem is probably in the scanner guns.

AP Is Not Pinging or Pings Sporadically

If you can't ping the AP, or the AP occasionally drops packets, then the scanner guns will not work properly. A properly connected AP should never drop any packets since it is wired to the LAN. Try the following steps to correct the problem.

  1. Unplug the AP, wait 10 seconds, and plug it back in. Sometimes a simple reboot is all the AP needs to start working again. If this doesn't solve the problem, follow the remaining steps.
  2. No Lights:
    1. If all three lights on the AP are off, Make sure the AP is plugged into a known-working wall socket.
    2. If the wall socket is known to work, and the AP is plugged in correctly, and the lights are still off, the AP's power cable may be bad, or the AP may be bad.
  3. Red Lights:
    1. If any of the LEDs are red, the AP has a firmware error and must be replaced.
  4. No Ethernet Light:
    1. If the Ethernet light is off, verify that there is an Ethernet cable connecting from the LAN to the Ethernet jack on the AP. If not, connect the AP to the network.
  5. Blinking Ethernet Light:
    1. If the Ethernet light is blinking, and there is an Ethernet cable connecting to the LAN, try replacing the Ethernet cable with a known-working cable, and moving to a known-working wall jack.
    2. If the Ethernet light is still blinking after replacing the cable and changing the jack, try a direct-connect test:
      1. Connect the AP directly to a computer's Ethernet port.
      2. Verify that the RJ-45 ports on both the AP and PC's have link lights.
      3. Run a ping test on the AP. You should get near-100% responses at less than 10 ms.
      4. If you are still dropping packets, the AP may need to be replaced.
