INTEL 3945 Reassociation/Deauthentication Problem

Hi All,

I used a Acer Notebook with INTEL 3945ABG without Power Save.
I used it to connect to a AP (bgn) whatever Atheros, Broadcom, CISCO, Marvell.

INTEL 3945ABG automatically try to do roaming (site survey) every minute.
Sometimes it will determine to roam and reassociate to the same AP after site survey.

1. Why it often does reassociation even I change the "Roam Aggregative" to "Minimal"?
2. Why reassociating to the same AP?
3. Sometimes it will deauthenticate (disconnect) to the AP?

Many different APs exists in my environment but no heavy traffic is going.

When I see the statistics in INTEL utility, it says the "Roaming Count: 1xx" and "Poor Beacon Quality: xx".

But I try to put them close or farer, no any improvement!

I also do not do any traffic between them, just only put them there.

Why?????????? 3945ABG is so difficult to use......................

 

try reinstalling drivers...with the newest ones...if you didnt yet.

 

When you setup the wireless there is a option to only connect to preferred networks, and only AP's if not using adhoc. This will keep it from connecting to AP's you do not own. Make sure your router/ap has a unique SSID name to distinguish it from others.

 

My Intel driver version is 11.1.1.11
I think it is the latest version.

And my SSID name is unique.

But I dont know why the INTEL 3945ABG sometimes reassociate to the same AP or deauthenticate itself and associate to the same AP again.

It should not reassociate or deauthenticate at least 1 week.
This is not acceptable even reassociating or deauthenticating once.

INTEL 3945ABG design is too sensitivity.
