Problem while configuring whireless bridge cisco 1602i

[kap1]

Hi everyone,

I have problem while trying to make wireless bridge configuration containing 2 cisco aironet 1602i access points. I was able to make the root device work but I have problem with repeater. Root is conected to my home router and is broadcasting ssid with internet access. While trying to configure repeater and set parent i get error:  Interface Dot11Radio0, cannot associate: Not specified parent (from SOME_MAC_ADDRESS). Also I don't know if it's important, but while specyfying station-role i get notification: Disabling 802.11n aggregation in WGB/Repeater/NRB mode. Root device is connected to my router and repeater is not as I want to create wireless bridge configuration between these access points. Can someone explain why it doesn't work ? Scripts I used to configure devices are listed below. 

========ROOT===========
configure terminal
interface dot11Radio 0
station-role root
exit
dot11 ssid NAME_OF_SSID
guest-mode
authentication open
authentication key-management wpa version 2
wpa-psk ascii Cisco123
exit
interface dot11Radio 0
encryption mode ciphers aes-ccm
ssid NAME_OF_SSID
channel least-congested
no shutdown
exit

==========REPEATER============
configure terminal
dot11 ssid NAME_OF_SSID
authentication open
authentication key-management wpa version 2
guest-mode
infrastructure-ssid
wpa-psk ascii Cisco123
exit
interface dot11Radio 0
encryption mode ciphers aes-ccm
ssid NAME_OF_SSID
antenna gain 0
parent 1 MAC_OF_ROOT
dot11 extension aironet
bridge-group 1
no shutdown
exit
interface bvi1
ip address 192.168.0.19 255.255.255.0
no shutdown
exit

Hope Both AP running same Code - can you check on the root AP config of BVI

check below example : run some debug and post the logs here :

Hello,

Will try to configure repeater from the site in a minute will update after I am done

It worked I don't know what was the real reason why my first configuration didn't work but with that guide everything worked perfectly. Thank you so much for help I will paste both scripts for devices maybe someone will use it in the future:

========ROOT===========
configure terminal
interface dot11Radio 0
station-role root
exit
dot11 ssid NAME_OF_SSID
guest-mode
authentication open
authentication key-management wpa version 2
wpa-psk ascii Cisco123
exit
interface dot11Radio 0
encryption mode ciphers aes-ccm
ssid NAME_OF_SSID
channel least-congested
no shutdown
exit

==========REPEATER============

configure terminal
interface dot11Radio 0
encryption mode ciphers aes-ccm
ssid test_wlan
exit
station-role repeater
exit
dot11 ssid test_wlan
guest-mode
infrastructure-ssid
authentication open
authentication key-management wpa version 2
wpa-psk ascii Cisco123
exit
interface bvI 1
ip address 192.168.0.19 255.255.255.0
no shutdown
exit
ip default-gateway 192.168.0.1
interface dot11Radio 0
no shutdown
exit
Now everything works fine, I can connect to both devices using ip addres in browser, in wi fi analyzer I see 2 same ssid and both root and repeater can ping each other and also default gateway of my home router. PC can also ping both devices
