Re: Intel Centrino 6205 and AP-225 headaches

The 2.4 will always be more than the 5ghz because there are fewer channels and more cochannel interference.  Fortunately most clients will go to the 5ghz band, instead.

 

What are the numbers for the 5ghz for each site?

 

Take a screenshot of your dashboard before we make any more changes.

They are all between 1% and 10% with the majority floating around 5-7%.

I'm not sure if I said this but the device with the the NIC mentioned can walk out of the these building and into a building without 225's and immediately connect to the SSID's.

Are you saying, after making the changes, devices still cannot connect?

 Yes. Just had a staff member test a machine and it happily connected to the SSID when in a building with an AP 135 but when the machine was taken into a building populated only with AP225's she couldn't even see the SSID's.

How many SSIDs are you running?  Do you have them hidden?  Are you running DFS channels?

3 SSID's. Not hidden. Default for Australian regulatory domain.

And to follow that up I remote connected to the machine in question last night and check all the settings on the NIC and they are correct.

You should open a TAC case.  It would be difficult to diagnose what is going on from here.

Re: Intel Centrino 6205 and AP-225 headaches

HI Colin, just thought I would let you know I have solved this. In another thread concerning this NIC you advised turning off “Advertise 802.11K Capability” on the 802.11K profile. Not the same issue but a small resembalance. In response to this the other person said they had read somewhere that older Intel NIC's do sometimes have an issue with 802.11K. So I disabled it and now all is fine.

Re: Intel Centrino 6205 and AP-225 headaches

Confirmed that this solution worked for me as well with a test SSID. Now I have to figure out the ramifications of turning off 802.11k site-wide vs. providing wireless dongles for users who have these older intel chips.

 

Does anyone have information on whether it's possible to configure 802.11k on a per VAP basis? Meaning, would I be able to create another SSID that has 802.11k disabled in the areas that need it while broadcasting the standard site-wide SSID on the same AP, or would it remove the feature on the entire AP, regardless of the various VAPs in the AP Group?
