[sdmumbai rrc]

Hi,

I'm facing issue with newly purchased Dell laptops(dell vostro 14 v3446) are not able to join in WLC.

I have check WLAN profile for these laptops ,all mapped correct,but laptops not able to join the same profile.

Only one(newly purchased) laptop is working fine with WLC profile,remaining laptop all config is same but not getting connected with WLC. 

Laptop wifi is working with another vendor APs.

But this particular profile working with my exciting user's laptop perfectly.

WLC/-AIR-WLC2106-K9-Firmware version—6.0.199.4

AP-AIR-LAP1131AG-A-K9.

Please advice me here to resolve this problem.

regards,vijesh

You will need to provide information other than what you've posted.  

What error message do you get on the laptop?

Can the client authenticate?  If not, can you try OPEN authentication?

Another thing, your firmware is very, very old.  I'd recommend you upgrade the WLC firmware first and see if you find any improvements.

Hi Leo,

Thanks for your response.

Client laptop trying to connect the SSID and once authentication key entered ,it will try for a while then error message come "could not connect...." 

As our suggested,i will create new profile with open authentication,then try to connect the laptop.

we have planned to upgrade WLC firmware in coming weekend.
