Can't telnet into Cisco Aironet 1041N

I have a Cisco Aironet 1041N (one of the standalones) that I'm trying to configure.  I was able to do this fine until today, and now I cannot telnet into the device.  If I use the web interface, it takes my credentials just fine, but I get "Authentication failed" if I try to go through telnet.  I have changed the default password and created a new admin user to no avail.  Does anyone have any ideas as to what could be going on?

Thanks in advance!

I don't think so, because the passwords work fine to get into the web interface.

try the default password.  You will probably find that http is configured for 'local user database' authentication, but telnet is configured for 'line password' authentication.

If you want the two to be the same, once you are in the cli, add the following config:-

line vty 0 4
 login local

The authentication all uses the same method when configured via the GUI.

Go to...

Security -> Admin Access

What is selected there?

I have no idea what happened, but I did a factory reset and reloaded my config, and all is well now - I can telnet into the device fine now.  Thanks for all the help!
