Solved: 9120AX login fails after reset

neil_titchener · ‎10-08-2020

Hi all and thanks in advance for any advice.

I have had the same issue now with two 9120AX APs where following a hard reset, pressing the reset button for longer than 20 seconds, I'm unable to login to the device either by SSH or console. Neither the username/password it received from the WLC prior to reset or the Cisco default Cisco/Cisco seem to work. During the initial setup i.e. out of the box, Cisco/Cisco worked.

Just as an FYI prior to the reset both APs were connected to a C9800 virtual WLC.

Any advice would be most welcome.

Thank you for all your responses and apologies for taking so long to reply. I have found the issue and as is the case for most networking issues the problem is the user :-). Our network is shared between two organisations, one already has WLCs deployed and use the default DNS method for finding the WLC. The new system I'm implementing is in a different network segment but I'm testing in a part of the network that is used by the other organisation. When I defaulted the AP it was using DNS and associating to the other organisations WLC and picking up the username/password configured on their system.

It's sorted now so thanks again for all your input.
