    <title>topic Client Ip address issue in Wireless</title>
    <link>https://community.cisco.com/t5/wireless/client-ip-address-issue/m-p/2287351#M164492</link>
    <description>&lt;P&gt;I have a 1142 AP which is connected to the access switch. I have configured the AP but the problem seems when the client tries to connect to the AP he is not able to connect. I have checked all thr configurations and all the required vlans are allowed on the trunk ports.DHCP is enabled and utilization is below 40%. ALso i am able to ping the helper-address from the AP. I can ping the core switch AP Management Vlan.&amp;nbsp; The client can see the required SSID.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I tried to run log messages on AP and found messgaes related to autthentication. like deauthenticating station --reason : previous authentication not valid...repeatedly&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I believe this is due to mismatch of keys in 802.1x WPA2 authentication. Please let me know in case anything else needs to be ascertained&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;﻿&lt;/P&gt;&lt;P&gt;﻿&lt;/P&gt;&lt;P&gt;﻿&lt;/P&gt;&lt;P&gt;﻿&lt;/P&gt;</description>
