Hi,<br><br>Thanks for your reply. I began testing different setups immediately. I located 1 AP which didn't regenerate the error (AP1) and swapped it with one which did generate the error (AP2). <br>I then saw that AP1 (which now was located on the place of AP2), began generating the same errors. The clients are fixed , so I tested with the same clients on that location. <br>
My conclusion:<br>1) The error probably has something to do with the WAP54G, but;<br>2) The error is only produced in combination with some clients (don't know if it's a hardware issue, because it seems to have nothing to do with the OS. OSX and Windows Vista/XP are all 'sometimes' producing the error.<br>
3) It might have something to do with overlapping channels, but my tests are not yet conclusive about that.<br><br>It's all so much trial and error... I decided to just buy another AP (WAP200) to test and see if the same error pops up. I'm also going to try an Asus WL-G330ge, just to be sure. More on that later...<br>
<br>Jelle<br><br>ps: The models I use are Linksys WAP54G, v3.1, with firmware version 3.05.<br><br><br><br><div class="gmail_quote">2008/6/11 Alan DeKok <<a href="mailto:aland@deployingradius.com">aland@deployingradius.com</a>>:<br>

</div> That's pretty definitive.<br>

</div> It's possible. If they're all the same manufacturer and software<br>
version, they could all have the same bug.<br>

</div> Run "tcpdump" or "wireshark" to look at the packets. Odds are the<br>
AP's *are* sending conflicting packets. Look for 2 packets from the<br>
same client IP && port, with the same RADIUS code and ID, within a<br>
second of each other. If the packet contents are different, then the AP<br>
is broken.<br>
<br>
i.e. You can believe that FreeRADIUS is broken, but *only* on your<br>
system... and not on the other 10,000 systems with 100's of 1000's of<br>
AP's. Or, you can believe that your AP's are broken.<br>
