Experts,

Running 4 self managed Cisco Aironet 1240AG Series Access Points.
WAP's have been working for 2 years and all of sudden all 4 units now state:
Packet to client 001b.6317.a954 reached max retries, removing the client.

They are kicking all clients off every 5 minutes so what they tell me.
I increased Max. retries to 128 (max setting)

There is never more than 20 clients connected to one of the WAP's.
If more info is needed feel free to ask.
Please advice,

Check you MAC Address authentication entry, it may be that you have used the maximum allowable clients. If so you may need to clear the MAC Address authentication or disable it.

Yes, that sounds like it could be the problem. Let me know if that doesn't fix it.
Cheers!

You need to use a Console Cable, it has a Serial DB-9 connection one that connects to the back of your computer and an RJ-45 connection on the other. You may need to set your speeds on your terminal server client such as hyper terminal to:

COM 1
9600
8
2
1

no flow control

If these settings do not work you may need to review your product manual that should have the instructions on how to connect to your WAP through a console (serial) cable.

Did you ever get this resolved? I've noticed my 1231 doing this to my handheld HP pocket PCs.

Yes, I deleted the SSID profile and re-created. Also, selected channels freq. according. They have been working for 10 days now.

You went into the AP, deleted the SSID, and then re-created it? Good idea. I'll try that.
