Cisco AP1400 Authentication Failed

I am using Aironet AP1410 for connectivity and the buildings are 20km apart.
I can see the bridges are associated but on Root Bridge its giving me authentication failed message. I am attaching the setting below, kindly let me know where is the mistake.

Can you post the config of the APs, removing any sensitive data?

Thanks

sorry i am new to it, dont know how to get the config. I have tftp server and have upgraded the IOS.
plz guide me in steps
connect a console to the AP, or if possible connect using telnet /ssh
When you login, and you are in enable mode (see the # next to device name) type

"sh run"

and paste here , after you remove username/passwords etc
I have attached the Config of Root and Non Root Bridge. The log at both ends is also in the same config.

Just a piece of information that both AP are associated but not Authenticated. I cannot ping Root from NonRoot Bridge. But i can see they are assocaited.
thanks

A fast way to solve your probem is:

conf t
dot11 ssid CONNECT
   authentication shared

Are you sure that aaa server 192.168.0.1 is working?
However, checking again the logs this isnt an authentication error!
This is due to some connectivity issue; wireless is subject to many and random radio interference problems, which can cause disconnections.

Can you check that your antenna havent been moved?
I dont know if it possible to check the frenzel zone for an 20km link!!
yes i think so
beacuse before i had different settings and i was able to ping from Roo to nonRoot and vice versa. Packet loss was also minimum but it was disconnecting.
But its just giving me Authentication Failed as u can see in log :(
are you sure there is nothing wrong in the configurations ??
antenna didint move bcz with same direction and everything i was able to ping b4 but the data transfer was not possible. But now i am not even able to ping :(
For me looks like an RF problem
20km is huge distance for a wireless link, and its functionality depends on many, easy to change, factors. In a 20km link, a few cm is huge change to antenna aligment

- Try to reboot AP to both sides.
- Try to change channel to "root bridge" AP.
- Create a new SSID, with no security /authentication and check if ti works. If does work, then increase security step by step, and check where is the error.

Check that both sides configuration hasnt been altered (i see default usernames and default snmp communities).
rebooted AP = no difference
changed channel = no difference
SSID = checking now
will check the alignment as well
HI ampranti
                   I have deleted the SSID and created a new one. This time i configured it with minimum configurations having WEP Mandatory only. Now i can ping Root from Non Root.
Still i am getting some strange log. Deviced are associated. Please check and let me know whats wrong.I am attaching the config as well as the log of both bridges

The SNR for this link isnt too good

Please give us the output of " sh dot11 association <MAC>" while link is connected



SSID [CONNECT] :

*************       192.168.12.3    bridge        NonRoot         self           Associated

sh dot11 association <MAC> , replace MAC with the real MAC adderss... It shows the signal of the link
i tried
NonRoot#sh dot11 association "added mac address"\
but it showed me nothing
came back to
NonRoot#
prommpt
If shows nothing then when you did it the client wasnt connected....
Just to be sure the <MAC address> is the MAC of the device on the other side..

For example:

1111.x.x.1111 <..........................> 2222.x.x.2222

If you are to 1111.x.x.1111 do:

sh dot11 assoc 2222.x.x.2222
as i told u earlier that i have recreated SSID etc and then i was able to ping Root from Non Root and vice versa.
Few hours ago i  did the realignment of the device as well and have changed IP addresses.
The associations log as requested by you is pasted below. Just to remind the log is taken after the alignment

Signal Strength   : -81  dBm & -82dBm
At the moment i cant find the specs with the minimum required signal level, but i bet its close to its minimum.
I cant think something different,sorry :(
you think that the signal strength is still too low?
cant i do something in radio settings to increase it?
whats the best way to align the device to have excellent signals?
should i keep same configuration while adjusting the device till i get better signals?
rotating the device for strenght will require rebooting the device?
is there any tool available to check the signal strength before making it live?
You can increase power or use antennas with higher gain (db)

whats the best way to align the device to have excellent signals?
Use access points to see signal, and align antennas until you find the optimal signal

should i keep same configuration while adjusting the device till i get better signals?
Yes
rotating the device for strenght will require rebooting the device?
No
is there any tool available to check the signal strength before making it live?
conf t
int dot 0
statrion-role scanner

(Maybe isnt available if you have old IOS)
Check this command reference:

thanks ampranti
you have been such a great help
i will do the alignment part one again and will let you know
What are the recommended radio settings for Root Bridge through Web Interface?
the  best signal strength can be considered between what range ?
Depends on your antennas, power etc...
-70 i think will be  ideal for 20km link....
hi
even after getting -79dbm strength i a m getting following logs at Root and Non Root
Is it bcz of poor signal strength?

Root Log
========
Information       Interface Dot11Radio0, Station NonRoot ************ Associated KEY_MGMT[NONE]  
Information       Interface Dot11Radio0, Deauthenticating Station ********** Reason: Sending station has left the BSS  


NonRoot Log
===========
Notification      Line protocol on Interface Dot11Radio0, changed state to up  
Error             Interface Dot11Radio0, changed state to up  
i have still made the device functional and to my astonishment the ping response is 1-5ms only :)
its working perfect
1 - Please let me know about the log i posted above, if slow signal strength mught create a problem in future, though the delay is 1-5ms on average.

2 - For checking signal strength  u told me about
conf t
int dot 0
statrion-role scanner

i am not able to use it :( since i am not a pro
please explain it and we will close this thread :)

i am really thankful to you and the support u provided. I learnt a lot from you :)

If there was a rating Higher than "A", i would have definately given it to Mr. Ampranti.  Really thankful for all the support and guidance. All tip and suggestions given were perfect and really helped me out in configuring the device. THANKS A LOT  :) May God Bless You
