Hi,
I have installed one 5508 with 3 AP in lwapp mode for use with a band selection features, but my client with a linksys WUSB600N
use connection to 2.4Ghz.
Why ? Can you help me ?
Thanks in advance

Also remember that band select must be enabled globally on the WLC regardless of whether or not it is enabled on the individual WLAN:
Step 1 To globally enable or disable band selection on the controller, enter this command:
config band-select probe-response {enable | disable}
The default value is disabled. .
There are few bugs, CSCtf03958 and CSCtg94454, to add a note to the WLAN config (think MFP) and the documentatoin to make this more clear.
Thanks,
Lee

Check your setting on the client device. Band select tries to make the 5ghz side preferable compared to the 2.4ghz. In the end, the client still makes the decision.

Hi Scott
Thanks for your answer, I want use a band selection because in a site I have hundreds of clients and I don't want modify the client configuration, and I need that the prefered band selection must be 5Ghz over a 2.4Ghz.
Thanks in advance

Here is another thread regarding ban select. Now if you want them on the 5ghz, you can always set the radio policy on the ssid to 802.11a only.

Hi Scott, my client need move in a 5Ghz the notebook a,N and use a 2.4 Ghz only for a old notebook 802.11 b,g.
Cisco have ensured that the band selection works fine but when I have tested it with a linksys it connect over 2.4.

Client devices make the final decisIon. It doesn't mean it will work for every type of client device. If you have a bunch of useres already on the 5ghz, then iI can see why other devices use the 2.4ghz. Band select doesntdoesn't force or make devices use the 5ghz band, it just make it look more preferable.

Hi Scott thanks for all and have a good day
ps:I have opened a ticket c/o Linksys support

Hi
I tried the band selection and I can not see the effects.
With some clients I always connect to 2.4Ghz and still others at 5 with Band Selection enabled and disabled.
Can you help me ?

What model of APs are you using? Band select only works with 1140 and 1250 series APs.
Did you globally enable band select on the WLC: config band-select probe-response {enable | disable} or from the GUI: WIRELESS>Advanced>Band Select.
Thanks,
Lee

Hi Lee
Thanks for your support.
I test a solution with a 1142 but configure a band selection only from a Gui
Wireless advanced band select.
Is not Correct ?
Thanks

No, unless you have globally enabled the feature in the two ways I mentioned, the config on the WLAN is irrelevant.

Ok then also gui is enabled globally but then why not work?
Security is also enabled for each WLAN
Today I tried with 4 clients
3 11n and a 11a but work equally at 2.4 well with the band select enabled or sometimes to 5
with another client with a linksys wusb600n work only at 2.4 Ghz

Provided everything is enabled, the radio policy is set to ALL on the WLAN, etc, all band select does is try and nudge a dual band client to try and see if they will associate on the 5Ghz band. Delays the probe repsonse on the 2.4 band accoring to the number of probe cycles you configured for it to do so, but it doesn't mean that it never lets a dual band client associate at 2.4. In the end, the client is the one that is going to make that decision. You would need to get a wireless packet capture to see if the band select is actually working, i.e. delaying the probe response on 2.4.
If you go to MONITOR>Access Points>Radios>802.11b/g/n and then Details, do you see any band select statistics? If not, then I would say get a wireless packet capture to see what is happening and then open a TAC case so one of us can take a look.
Thanks,
Lee

Ok in monitor radio 802.11n detail I can see some statistics about a band selection but without effect over my client.
How I can capture a wireless packet ?
Thanks
ps:Unfortunately my client buy the solution only if the band selection work
