We've just purchased 4 of these WAPs and are now getting them set up - first issue we've run in to is it blinks Red / Yellow / Green. They didn't come with a manual, and the documentation on this site doesn't mention the LED being capable of blinking yellow so this has caused a fair amount of confusion. Can anyone shed some light on this?
The APs you've purchased are most likely running on controller-based IOS. If you don't have a wireless LAN controller (WLC) then you'll need to convert the AP to run autonomous IOS. This can easily be done if you follow this procedure: Using a TFTP Server to Return to a Previous Release
If you don't mind, I've got another question - we actually do have a controller, but are unable to connect to the WAP (it does have an IP and we can ping it) with SSH or Telnet, and sticking it's IP address in the browser doesn't work either. What've I missed?
