Wlan client connects the second or third time

Patrick Werner — Sun, 04 Jul 2021 07:21:55 GMT

Hello Community.

Following scenario: If a wireless client switches from one Wlan to the Wlan with WPA2/AES Authetication on the same AP, the client doesn't connect at the first time. He has to click two, three or four times to connect until, in connects.

The WLC in installed at the central office, these problem occurs in a branch office, all AP's are in Flexccoenct mode. The switch betwenn Wlan that uses MAC Authentication and Web Authentication works fine, it works fine too if the client switches from the 802.1X Authentcation Wlan to the MAC or Web Auth. Wlan.

Wlan 1 = MAC Authetication

Wlan 2 = 802.1X Authetication

Wlan 3 = Web Authetication

The Wlan Switch betwenn these Wlan works., but if the client tries from one of these Wlan to the WPA2/AES Wlan it doesn't connects the first time.

Any idea ? Regards and thanks in advance

You need to enable Fast SSID Change on the WLC. This is located in the GUI under the Controller tab. This allows you to switch between SSID's fast or else you have to wait like 30 seconds.

I agree with Scott.

Try the Fast SSID Change and let us know if that works.

Choose to enable or disable the Fast SSID Change option. If the option is enabled, the client connects instantly to the WLAN between SSIDs without having much loss of connectivity. Normally, each client is connected to a particular WLAN identified by the SSID. If the client moves out of reach of the connected access point, the client has to reconnect to the controller using a different access point. This normal process consumes some time as the DHCP (Dynamic Host Configuration Protocol) server has to assign an IP address to the client.
