ThinkPad 11abgn driver ver.7.4.2.105 - excess event entries

[Kaz]

On 10/17/08, I updated my wireless ThinkPad 11abgn driver from version 6.0.3.94 to 7.4.2.105. The update was a nice improvement as I now connect faster than with the older driver. However, although no impact to my T60 performance, ever since the new driver was installed, the following has occurred:

1. A new entry in the Event Viewer called ACS
2. Multiple "ccxroaming" entries are generated every time my laptop comes out of standby (anywhere from 4 to 7 entries each time!)
3. Since 10/17/08, I have generated 951 ACS events!!

For example, this morning, after coming out of standby (AC mode), the following entries were generated from oldest to newest:

I can understand Lenovo possibly wanting to generate this information when testing a new driver in-house, but does this really need to be passed on the end user?

I have this same problem with my T400. I am running the Atheros 11b/g driver dated 9/16/2008, version 7.4.2.134.

My system manifests weird behavior on recovery from standby and hibernate -- I suspect is related to the WiFi or sound drivers. If anyone has a suggestion on how to fix this problem, I would greatly appreciate it!

Check and make sure that acs.exe is from the same distribution as the driver depending on how you installed the driver. An older acs.exe in system32 directory can cause this problem. Just updating the driver manually will not update these files.

To make sure, download the driver software, run it to expand the distribution in the DRIVERS\win directory. Then run setup.exe in that directory to copy the correct files to the system32 directory.

At least that is one problem that caused the suspend/hibernation problem in my case.
