Some laptops unable to join WPA2 SSID

Hi guys,

I have a problem here with many laptops unable to join my guest Wifi network.

Strangely mobile phones all work ok.

Unable to pinpoint which model of laptops as they are random. I tried with Thinkpad and it works but not on Surface Pro.

How do I trace this issue?

I am using 3802i AP (China H domain).

I am using WPA2 with a 8540 WLC controller.

Re: Some laptops unable to join WPA2 SSID

1. what is the frequency you are configured in SSID. is it 2.4GHz or 5GHz. or both?

 

2. Are those laptops able to see SSID? or cannot see SSID

 

3. Are you have enough DHCP addresses to lease

 

4. is this new issue or, is that was there from beginning?

Re: Some laptops unable to join WPA2 SSID

Both frequency are broadcast. 

Laptops can see SSID.

Yes only used few from scope. There are thousands more DHCP avail. 

This is a new site setup. Brand new APs.

SSIDs are used elsewhere worldwide via same WLC, so only difference is flexgroup, apgroup, RF group and AP is Chinese model.

Re: Some laptops unable to join WPA2 SSID

Which IP address have you used for the virtual-interface?
I hope not an internet routable like 1.1.1.1? You must use a private one there, like 192.168.245.10.

Re: Some laptops unable to join WPA2 SSID

please check if you are using WPA2+AES or WPA2+TKIP ?

 

or paste the output of the command here from WLC.

sh wlan <id>

Here is my sh wlan output for that SSID below.

Re: Some laptops unable to join WPA2 SSID

Can you install wireshark on a client and run a capture while you connect to the SSID?
I wonder if it just fails for DHCP, or something else.
A "show client detail macaddress" might also show more.

Re: Some laptops unable to join WPA2 SSID

Ok will try to get that capture, but from what I noticed, the moment the password is keyed in, it immediately responds as "unable to join this network". It is almost immediate, does not seem to be even trying to get past the AAA state.

Re: Some laptops unable to join WPA2 SSID

As per your ouput, you enabled FT-PSK.

 

FT-PSK(802.11r)......................... Enabled

 

Please disable it and use only PSK then give a try again.

Re: Some laptops unable to join WPA2 SSID

I am unable to change that as this is standard config we use worldwide and there are no problems elsewhere.
Will try to capture debug on client mac address..

Re: Some laptops unable to join WPA2 SSID

Really? Because 802.11r is known to cause a variety of issues, mostly with older Wi-Fi Adapter drivers.
