Re: Intel Centrino 6205 and AP-225 headaches

Colin,

Please find my answers below:

1) This is not specific to one user. We have had 50+ users reporting the exact same issue. All of them on 6205 or 7260 and in buildings with AP225.

2) AES

3) 20 MHz (on both a and g)

4) 6.3.1.5

 

The clinets are not roaming. This happens while they are sitting at their desk. All our 802.11k settings are left to "default".

 

Navid.

Navid,

Pick one access point where you have seen the issue and give us the output of "show ap arm state ap-name <name of access point>"

Re: Intel Centrino 6205 and AP-225 headaches

Navid,

 

It seems like you have very, very good density.  How far apart are your access points and how many SSIDs are you broadcasting?

Re: Intel Centrino 6205 and AP-225 headaches

I know the APs are pretty close ! About 40 feet between every two AP on average. We usually broadcast three SSIDs (one 802.1x authenctication for the Corp network and two "guest" SSIDs with PSK auth).

This is just a sample building. We have the same issue at other buildings with AP225s as well.

Re: Intel Centrino 6205 and AP-225 headaches

Navid,

 

Okay, we need to get a sampling of your utilization in the Air.  It might be after hours now but let us see the output of:

 

show ap debug radio-stats ap-name lsnj-3-ap12 radio 0 advanced | include intvl,Busy
show ap debug radio-stats ap-name lsnj-3-ap12 radio 1 advanced | include intvl,Busy

Re: Intel Centrino 6205 and AP-225 headaches

Has there been any developments on this? We have recently installed a bunch of AP-225's and the only devices having trouble connecting are those with the Intel Centrino 6205. Have got the latest drivers from Intel still no joy.

Guru Elite

Re: Intel Centrino 6205 and AP-225 headaches

The issues that the user had was from almost 3 years ago.  Can you be specific about any issues that you are having?  What do you mean by "having trouble connecting"?  Do you mean it never connects?  What percentage of the time does it stay connected?  Are you using encryption on that SSID?

Re: Intel Centrino 6205 and AP-225 headaches

They cant connect at all and on most occasions can't actually see the SSID's. The SSID's have not changed at all during or following the new AP installation. One thing I will add, after reading the preceeding connects is that I believe the density of these new AP's in these new buildings is way to high. Not my design but mine to manage.

Guru Elite

Re: Intel Centrino 6205 and AP-225 headaches

Maybe, maybe not.

How many SSIDs?

What is the distance between APs?

What is the output of "show ap arm state ap-name <name of ap>" of one of those APs?

What is the ARM minimum and maximum transmit power in the ARM profile?
