I have a weird and annoying problem. My X200 will detect wireless networks but refuses to connecto to them.
It's a brand new computer that I just got.
ThinkPad X200 7454-2HU, running Vista x64.
Latest drivers installed, all downloaded using the Lenovo automatic driver download application.
The driver detected in Device Manager is : Intel Wifi Link 5100 AGN.
There is no problem with the wireless network (other computers connect to it without any problem).
I tried to cancel the "n" option, leaving it with a "b/g", but it didn't help.
There is only one problematic device in the Device Manager, and it is "SM Bus Controller" (Can't figure out what it is and windows update nor Lenovo update do not solve this problem).
When I use "Intel ProSet/Wireless Tools" Diagnose, I get:
Hardware Test: Passed (Wireless Hardware is enabled)
Driver Testassed. Driver is loaded. NET w5v64 Versio: 188.8.131.52
Radio Test: Passed. Radio is ON.
Scan Testassed. There are 12 Networks available to connect.
Association Test: Failed. Not Associated.
When I look at the Statistics, it seems that the card is only receiving bytes (nothing is sent).
What do you think? Is it a hardware or software problem?
Any idea what can be done if it is a software issue?
Solved! Go to Solution.

To fix the error with the SM Bus Controller, you should install the Intel Chipset software:
I am not sure if this will fix your wireless issue, but it is not going to hurt it either.
What is the version of your wireless driver? Have you tested your wireless using PC Doctor?

OK. I downloaded the Intel chipset and the SM problem was fixed.
Wireless still not working properly.
The driver I am using is 184.108.40.206, Dated 7/8/2008.
I don't have PC Doctor. Any other suggestions?

There are known problems with Vista and WiFi that did not occur under XP mostly because Vista does more than XP (such as IP6). First check that your WiFi router has the latest firmware.
Then check out:

Interesting links, but it didn't solve my problem.
I tried to change the DhcpConnEnableBcastFlagToggle but it still doesn't work.
Any other ideas?

Forgot to mention.
I talked with the Lenovo tech support, and they say that if I see wireless networks but can not connect to them
then it is probably not a hardware problem.
I'm still not convinced completely...

You can post a question on the Microsoft newsgroup/forum that deals with wireless networking:
Also, consider using www.crossloop.com which is an on-line consulting service. I think you'll find someone whose fees might be very reasonable. There are consultants that deal with wireless networking issues.

I do not think the problem is with the router.
I even tried to login to my university wireless network (Which is vista verified...) and the computer will not connect.
I always get the same message: "Wireless association failed because windows did not receive any response from the router"
Does any of you guys have X200 and Viste x64 machine running smoohtly? maybe we could compare exactly the configuration and figure this thing out?

I am running 32bit Vista Business with access connections and an Intel 5300 card. I am using driver version 220.127.116.11 which was just released late yesterday, I believe. I do not have any issues connecting to any wireless network. See if you can install this update and try it.
Have you tried connecting to a wireless router that does not have security enabled?
