We have had mixed results with Ubuntu's default network manager
from 12.04 until the current. Have you tried an alternative
wireless manager like WICD?<br>

<div class="jive-rendered-content">HI I am having problems
authenticating client computers onto the wireless network
using a Cisco AP1252 via FreeRadius 2.1.10 on Ubuntu 12.04.2
serves<br>
<br>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
Setup:<br>
I have a Cisco AP1252 wireless Access Point connected to a
Cisco ASA5510 on subnet X.X.5.Z The access point ip address
is X.X.5.101 <br>
The ASA on another port is also connected to the wired network
on a different subnet X.X.0.Z <br>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
On the wired network are two radius servers - Ubuntus servers
running FreeRadius 2.1.10 which are running fine and reliably
authenticate wired users for ssh connections to the ASA and
importantly to the AP1252 as well (The radius servers ip
addresses are X.X.0.191 and X.X.0.192)<br>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
Problem:<br>
When a wireless user tries to connect to the wireless network
via the AP1252 after being disconnected form it for a while
(or after waking from a long sleep) they are never
authenticated. They just try over and over and never obtain an
IP<br>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
Interestingly in such a case neither Ubuntu server shows any
sign of receiving an authentication request from the AP -
Both ubuntu servers are running in debug mode so they show any
activity - there is none<br>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
Oddly:<br>
If i try to authenticate a user wirelessly to the AP and leave
it in the usual state of trying over and over (with no visible
activity on the ubuntu servers) BUT then go to a wired machine
and attempt to authenticate an ssh connection to the AP1252
using a terminal command ssh <a class="moz-txt-link-abbreviated" href="mailto:user1@X.X.5.101">user1@X.X.5.101</a> THEN as
soon as I hit enter on that request (and before I enter a
password for the ssh connection) THE WAITING WIRELESS USER IS
IMMEDIATELY AUTHENTICATED and assigned an IP address (and the
ubuntu server shows the authentication activity for the
wireless user)<br>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
Please help me understand what might be causing this behavior
- it seems like the AP sleeping and the wired ssh request
wakes it up so that it sees the pending wireless user waiting
and then acts on that completing the wireless user
authentication request<br>
<p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p>
Help<br>
