Logging wifi accesses

I have a 871W router with a wifi dot11 radio setup. It sIP address is

10.0.0.1

When a station connects, I get logs such as:

Mar 28 06:18:14 10.0.0.1 1417: %DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station 0025.004d.4765 Reason: Previous authentication no longer valid SSID[VaxinationWiFi]

Mar 28 06:18:16 10.0.0.1 1418: %DOT11-6-ASSOC: Interface Dot11Radio0, Station 0025.004d.4765 Associated SSID[VaxinationWiFi] AUTH_TYPE[EAP-LEAP] KEY_MGMT[WPAv2]

However, I would like to also log the actual authentication (which username is being used), especially invalid authentication attempts (hacker trying to get in for instance).

The router is setup with its own local radius server.

What sort of statement do I need to add to cause a syslog message to be issued for both proper and improper login attempts (either at the dot11 level, or at the radius level).

I have login on-success login on-failure

Those do cause syslog mkessages to be issued, but for actual logins to the router's CLI.

Any hints on what to look for would be appreciated.

Relevant bits (I think)

Loading thread data ...

Normally you would use AAA accounting for this; however the local RADIUS server doesn't support accounting.

We don't really have a good solution for this ... you could turn on radius debugs. (Of course, the debugs will go away on a reload ... you could stick "do debug ..." in your startup-config tho.)

OK, so basically, I have to setup a real Radius server on a server to get the acounting data. Will this also give me the invalid login attempts ?

This would also let you use PEAP clients (which are rather more prevalent than LEAP/EAP-FAST.)

Yep!
