AP Association Problem

                   I have one 1242AG Access point with me. This AP is used to provide connecitivity to handle held devices. The issue I am facing with this AP is that, whenever the client connect to this AP it roams around to the nearest other access point which is also 1242AG access point. The nature of SSID is non broadcasting and i have static 128 bit WEP key enabled. I have checked and all allowed vlans is passed on the connected switchport. I have asked checked remaining config. But found a discrepancy. I have set power client and power local to 14dbm. While the other AP uses,

power inline negotiation injector override

power inline negotiation prestandard source


Does this command over ride the choice of client to join an AP. I have also checked for other SSID and works fine which uses WPA authentication format.

The keys on both the AP are different. I feel it is a authentication issue. But can anyone help to point out anything else?

AP Association Problem

Hi Pravin,

The power inline negotiation injector override indicates a power injector is installed and the access point is configured to override the inline power checks.

If the switch can provide sufficient inline power but its IOS version does not support the Intelligent Power Management feature, you can get CDP error messages on the AP and both radio interfaces will not come up. In this case you will need to configure the AP (not the switch) to use a pre-standard inline power mode with the command power online negotiation prestandard source. This indicates to the AP that the switch does not support the intelligent power management and therefore the AP will never attempt to go into low power mode and wait for the negotiation before moving to the high-power profile.

Can you please paste the logs from AP console.

Thanks. But my concern is the AP is not using any power injector. The switch to which both AP's are connected is a PoE Switch.

Hello Pravin,

Can you also post the config of the SSID used show wlan WLANID ?

Are there other SSIDs that work fine on this particular trouble AP?

dot11 ssid Handheld

   vlan 40

   authentication open

encryption vlan 40 key 1 size 128bit 7 **Encrypted Key** transmit-key

encryption vlan 40 mode wep mandatory

I am not able to see debug client option...

i can see show vlan (not wlan) which shows some data in Rcv & TX. I strongly feel that the keys might be different

Re: AP Association Problem

HI Pravin,

1st: Check the key.

2nd. Update the driver of the client.

3rd:You can change the retry feature, do this:

1. go to enable mode

2. go to config (conf t)

3. in do0

4. packet ret 64 drop

This will tell the AP not to remove station if it misses retry count, so it will stop your continuous associations, regardless of root cause.

If still falied then please provide more logs to find the exact cause.

Re: AP Association Problem

I believe the access point is autonomous since the OP stated the power local client command.

Can you post the AP config? These AP's are pretty old so it wouldn't surprise me if maybe the radio is going bad or the AP itself. With autonomous AP's it might be easier to copy a config from an existing working AP and edit it and upload it to the non working AP.
