WiFi connection problem

[abk]

Hello every body:

I am have WiFi connection problem on my X200 NoteBook.
It disconnected with the AP intermittently.
It will take long time to reconnect to the AP.

I am now trying to find out what is the root cause. So, I got the Access Connection log which I paste part of it at the end.

Is there anybody understand the log and what is the reason of the error?

The log are as folowing:

As a simple test, try uninstalling access connections and use Windows networking. See if wireless works reliably then.

It may also be worth changing your channel that the router is using to see if that's a problem. I've found occasionally that wireless devices can disconnect intermittently if there is other wireless devices in my area on the same channel.

Check ALL the power and performance settings related to WiFi operation on your ThinkPad, including in Access Connections and the WiFi driver in Device Manager. There are lots of message threads on this here, and in other places on the web.
