Cisco 1130AG wireless interface flapping

Hi all,

I am trying to configure a Cisco 1130AG. I did one a few weeks back, but stupidly didn't keep a copy of the config. I think I'm going about it the same way, and I can see the WPA-protected SSID that I've created, but when I connect to it my XP machine keeps disconnecting and reconnecting approx every 10 seconds. I can't find anything obvious wrong with the config but since these aren't my speciality I'm sure there's something wrong in there somewhere.

I need to get it working approximately yesterday so I'm awarding high points for this one! Full config posted below for completeness. Very grateful for any insight....

It looks good to me, it should work if you enter the correct key unless I am missing something.  You can compare with: http://www.cisco.com/en/US/products/hw/wireless/ps4570/products_configuration_example09186a00801c40b6.shtml

Thanks for that. I can't see anything missing either, hence my confusion. I wonder if it could be a fault with the hardware? I can see the wireless network set up above but the machine just connects and disconnects constantly. No traffic is passed.

Will try connecting from another machine and see what happens.

Update - the fluctuating radio interface seems to only happen when it's configured for WPA connections - with no encryption it works fine. Don't know if this jogs anyone's memory?

Got it. The error is with the PSK, so viewers of the site couldn't have seen the error because I blanked out the key.

I entered the command in the format: wpa-psk ascii 7 keythatiwant

when in fact what I should have done is this: wpa-psk ascii keythatiwant

and then the AP encodes the PSK and puts it back in the config with the "7" in the format: wpa-psk ascii 7 0201165A5321C65E7362512000C3212F
