X220 and other ThinkPads - Wifi drops? Try my method.

2014-10-10, 21:39 PM

Hello,

 

about week or two ago, I maybe finally found solution to wifi connections problems on specific routers in channel N mode (Intel wifi card). I wanted to assure myself, that my method works (atleast for me), so I've been waiting last few days. Now, wifi is still stable and I can rely on it, however it sometimes takes a bit time to connect (does not matter, if I resume from sleep or simply power on). Access Connections works fine as well, no needs to remove it.

 

Step 1: Create system restore point (I can't provide warranty, however in my case on X220 and E130 this method works)

 

Step 2: Download driver for your Intel Wifi card (to prevent You from having none as you uninstall current version). Open this page, select your card, OS and choose file, what's name contains ...Ds... (for example, Wireless_17.1.0_Ds64.exe). These files with such a letters contains only whole driver without any additional applications, and they have worked for me better than the rest.

 

I would like recommend you to download the latest driver version. Reason is simple - I hadn't tried older versions. Furthermore, new versions should fix some security problems. Anyway, if you are not really IT professionals (I admit that I am really not), then choose, like me, the newest version. However, if you want to try older version, don't forget to tell others about your result! :)

 

Step 3: Uninstall current Lenovo wireless Wifi driver, Intel PRO/Set and so on. You have to be sure, that your computer contains NO wifi software. As written above, you can keep Access Connections installed, if you like them.

 

Step 4: Restart your machine.

 

Step 5: Install previously downloaded driver (once again, it should be file with phrase "Ds" in its name).

 

This should be all. There is no magic on it. Our X220 and E130 were constantly losing connections (neverending reconnect attempts, yellow triangle on wifi indicator etc., when ALL other devices worked perfectly). In our situation, problem is inside Lenovo drivers. Even generic drivers from Windows Update had not ever worked.

 

Do you have any experience with this method? I hope, that it will work for more people too.

 

Please, forgive me my horrible english. I am only triyng to share some help.

 

Regards,

skrble

 

EDIT: some phrases to make my text more clear and give it more sense

EDIT2: added my recommendation to download latest driver

Interesting, I have been battling with this issue on my X220 for more than 6 months now (since i decided to run software update (after long time not updating anything) and this problem started...

 

I tried uninstalling, reinstalling drivers, cleaning stuff, to no avail. I also tried intel wifi drivers and it didnt make any difference...

 

But I never stumbled upon this, two separate driver sets, S and DS... Do you happen to know what's so different about these drivers that makes it work?

 

In any case I just swapped out the Intel 6205 card for a broadcom based one after flashing a modified bios that removes the white list for lenovo approved adapters.

 

And I've not had any disconnections yet. I'll keep this in mind in case I upgrade to a Wireless AC card in the future, which will likely mean going to an Intel card, unless I find a broadcom based one.

Yeah, its crazy. In my case, I hadn't touched anything, but it really started itself (I know, in IT is this phrase a bit ridiculous).

 

The main point is to clean your OS from any previous drivers, which could possibly harm your new installation. I made quite a hard searching, when I was opening every (eventually) possible folder and manually deleted everything, what remainded after Intel PROSet etc. Tell me, do You think, that cleaning registry (even via automatical process in CCleaner, for example) could do it's role? I am still talking about the middle-part, when You uninstalled all previous drivers and Intel applications.

 

Feel free to add anything to my guide! All I want is to finally get some result (I've been facing this horrible issue since May 2013) . I spent tens of hours trying to finish this flea-work, and I would like to help others and help them preventing this situation.

 

Cheers,

skrble

Hello,

 

I believe one set of drivers contains management and administrative tools for system administrators, while the other, smaller package is just the drivers and intended for end users.

Exactly. Mine experiences say, that if you don't need these tools, it is better to download drivers only. Furthermore, package with tools hadn't solved my connection problem.

This worked for me too. I'm on an X220 with Win10 Technical Preview. The plain vanilla Intel driver holds steady.

Thanks so much for posting this solution!
