I have setup a FreeRadius-server and try to get it operational with a Linksys WAP54G AccessPoint. This seems to work highly unreliable.

I posted a question about this on the Linksys support forums, but no luck so far: http://forums.linksys.com/linksys/board/message?board.id=Access_Points&threa...

No output at all? I would suspect the network - firewall, mac filterning on the switch etc. Use wireshark to see if AP is sending radius packets.

Nothing will go through the switch if mac filtering is enabled. You need to see if packets are leaving the AP. How can I check that? Does the WAP54G have the option to check that? As far as I can see, I can only check if any data gets to the FreeRadius-server.

Besides, no filtering is enabled. All data from the internal network van reach the radius-server. That's proven, because in some cases, the Radius-server recieves data from the AP and I get a successfull logon. According to this thread, the problem occures as soon as one of the requests of the WAP54G is unsuccessful (a package is lost): http://www.linksysinfo.org/forums/archive/index.php?t-36702.html

So what is the situation? Does the AP start working when you switch it off and on again? Or not? Can you come up with a clear statement of facts and not point to conclusions of somebody else (who might not have the same problem as you do)? Ivan Kalik Kalik Informatika ISP

Right now I have 1 FreeRadius-server and 3 WAP54G AccessPoints. When I configure the AP's with WPA-Enterprise and point them to the FreeRadius-server, the FreeRadius-server doesn't get any data from the AP's.

I have one WAP54G that works most of the time

OK.

One other has worked once. The third has never worked.

Connect those two directly to radius server (or whatever runs tcpdump/wireshark). If you still can't get anthing, retun them and ask for your money back.

Searching for a solution for this problem, I bumped in more complaints about the WAP54G with FreeRadius. For some reason, they stop working when some request-packages get lost.

If that's the issue I know about, you restart the AP (switch it off and on again) and it starts working again. That doesn't sound like your problem. Ivan Kalik Kalik Informatika ISP

With one AP (the one that works most of the time) this is the case. Sometimes nothing comes through. After a hard reset (power off) it works again. For a while...

As my two cents, I have a W54GS using FreeRadius in a rather complex setup, but your basic troubleshooting should be the same. I have read it a few times on the post, while you can prove there is some communication between your WAP and your FreeRadius install, the problem remains on how MUCH is actually happening. Is the WAP only sending 1 in 5 authentications? Is it sending all? or less? The best way to prove this is to wire it directly to a box so you can do a packet capture, and see if it is doing exactly as you expect. That can remove the WAP on the communication side, as well as give you a little insight to what is broken from that point on. Providing the information you get back (Minus the dump file itself, unless someone asks for it specifically) will help people on the list find out what this AP is doing. As well, is it at the latest firmware? If you want to get a little more hands on, there are a few things out there on how to create a passive tap, and you can use that basically anywhere, in your current infrastructure to see if it is the network between the two devices that is broken. With Linksys it is kind of silly, but you usually have to power cycle it, if it loses the Radius server, so it is forced to re-negotiate its connection, and allow authentication. I have seen this personally, and read a lot about it online, though I haven't come across anything from linksys themselves about it. Regards, Seann
