WiFi stops to work irregularly on X201 (major issue of X201)

2021-07-25, 20:02 PM

I still face this problem on my 3rd X201 - the WiFi stops to work on X201, irregulary. The green led turns off, and sometimes there is no WiFi Device after i call the Fn+F5, only BlueTooth. 

 

This problem has many users of X201. And this problem is ultra annoying, mainly because that nobody knows what is the cause of this problem. It points on Lenovo: bad drivers they damaging WiFi cards. On my both previous X201 i faced this problem. And my actual third X201 suffers with this WiFi problem as well. This is not coincidence. 

When i change the WiFi card for new, it works for some time without any problem. But after some time it starts to stop working. The cadency of the problem grows and sometimes i restart the driver or all computer many times to "force" the adapter to work for some time. 

 

I also found that damaged wi-fi adapter (with this issue) corrupting the Sleep process of my X201. The laptop is not going into the Sleep mode, instead of this it is hard switched off.. 

 

So i here are my known procedures or tip about this issue: 

 

1) First i found that it helps when i restart the PC, or at least i Sign off. The reactivation of WiFi adapter/driver helps to sign on the wi-fi adapter correctly. It works for some time, sometimes for minutes, sometimes for hours, sometimes even for days.. 

 

2) Later I found that it helps when i reinstall the wifi driver when the wifi stops to work. Again, the reinstallation process helps to sign on the WiFi adapter correctly and it works for some time. 

 

3) Some people say that the chipset reinstallation might help too. 
https://forum.thinkpads.com/viewtopic.php?t=130915

 

4) i also noticed that resetting of embedded controller might help:   
"Resetting the embedded controller can help problems like these by removing the battery and holding down power button for about 15 seconds."
https://forum.thinkpads.com/viewtopic.php?t=130915

 

5) I found that this driver should fix the problem: https://drivers.softpedia.com/downloadTag/Lenovo%20ThinkPad%20X201%20WiFi%20Driver. At least one user claims this on this thread: 
https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/Thinkpad-X201-WiFi-not-working/m-p/3634196?page=1
But those drivers are not for N 6300 or N 6200, etc. They are not stated there.

 

6) The problem could be also in BIOS, as Lenovo blocks some non approved WiFi cards. But i always used offical WiFi cards (N 6200 or N 6300). 
[i]"Could be 1 of two things I can think of, Something is wrong with the PCI-Express slot for the WiFi card (though odd cause BlueTooth is working), 2) Lenovo is known to black list non approved WiFi cards making them not work. I have had to BIOS flash one of my Lenovo laptops to use a better (non approved) WiFi card."[/i]
https://forums.tomsguide.com/threads/lenovo-thinkpad-x201-wifi-not-working-visible.419645

 

7) Is there some 'secret' driver from Intel for Intel Centrino Ultimate-N 6300 or Advanced-N 6200? On Lenovo EOL site they are those same drivers for years. 

I did not try all those tips (had no time), but i will focus on this. 

 

It seems that it is a problem of whole X021 Series. But isn't a problem only for some X201 models/CPUs (i5)?

"I have managed dozens of x201 series laptops and can say I have not seen a more consistent rate of problems 
with wifi adapters than with this specific series. In most cases, the internal wifi antenna is 
damaged/defective and must be replaced. A good indicator of this is when the green wifi symbol will not light 
up (and the bluetooth symbol is lit), or having the wifi light turn off shortly after enabling wifi (Fn+F5). 
Of course, make sure the main wifi switch is set correctly and that you enable all wireless radios with Fn+F5. 
The switch is on the left hand side of the laptop and on the end closest to the user.
I have had occasional success by uninstalling the wifi network adapter from Computer Management, which forces 
the laptop to reidentify the adapater on next boot."

 

The crucial problem is that i do not know where is the problem and how to fix it. Is the problem is in wi-fi adapters (series) - i purchasing them as new from eBay (China). Or is the problem in my motherboard or any other hw component (like hw radio switch, as some says)? Or is the problem in drivers/adapter software that damaging the wi-fi adapters? 

 

So should i buy WiFi adaptors, or new MB, or new X021 with another CPU? Or is the problem in SW/drivers? What will happen if i switch my HDD to new X201? Will i bring this problem via my OS to new X201 as wel? Serious quastions. But i do not know nothing about where is the problem. 
What is sure it is that it is Lenovo bad work.. 

 

Is there anybody who successfully fix this problem?! 

 

Let's share your knowledge here, please. 
Thank you!

p.s.: for LENOVO ThinkPad X201 there are allowed only those offical WiFi cards, and on this link(s) there is stated none of these:

Intel Centrino Advanced-N 6200                  60Y3231
Intel Centrino Ultimate-N 6300                    60Y3233
Intel Centrino Advanced-N + WiMAX 6250 60Y3195
Intel Centrino Wireless-N 1000                    60Y3203
Intel WiFi Link 5300                                      43Y6495
Intel WiFi Link 5100                                      43Y6493
Intel WiMAX/WiFi Link 5350                        43Y6533
Intel WiMAX/WiFi Link 5150                        43Y6539

QUESTION: is it possible to use with X201 some newer/better WiFi cards? Is there some way to do it???

Hello TP-X,

 


Greetings

 

 

As there may be possibilities of a non whitelisted card working, but as soon as BIOS gets updated or with the Windows update, there maybe chances that it would likewise stop working as it updates its hardware recognition protocol.

This same reason why it is recommended to choose only those compatible listed parts so other features like sleep would work as intended.

 

 

Regards,

Hello,


Have you tried using a different white-listed/Lenovo-supplied Wi-Fi card, just in case the one inside the X201 has begun to fail?  That's an eleven year old model, if memory serves, so it is possible the card has failed over time.

 

Regards,

Re:WiFi stops to work irregularly on X201 (major issue of X201)

Hello, i always used only white listed WiFi cards on my X201, i.e. N 6200 or N 6300. I know that X201 is an old model now, but it is still perfect for me (i really prefer the X61 old school architecture). Anyway, in last decade i used three X201 (with white listed WiFi cards of course), and each of them suffered with this "WiFi stops" problem. Theoretically, it might be coincidence that all three X201 i used had bad WiFi cards, but there is plenty of people they faced the same problem during the years, right after X201 release. It is not the new problem of 2021 comming from the age of old model.

 

Again, the citation from one service man:

"I have managed dozens of x201 series laptops and can say I have not seen a more consistent rate of problems with wifi adapters than with this specific series. In most cases, the internal wifi antenna is damaged/defective and must be replaced. A good indicator of this is when the green wifi symbol will not light up (and the bluetooth symbol is lit), or having the wifi light turn off shortly after enabling wifi (Fn+F5). Of course, make sure the main wifi switch is set correctly and that you enable all wireless radios with Fn+F5. The switch is on the left hand side of the laptop and on the end closest to the user. I have had occasional success by uninstalling the wifi network adapter from Computer Management, which forces the laptop to reidentify the adapater on next boot."

 

So this is not the coincidence i guess. It points on Lenovo problem. There must be some reason and i still try to find what is it. Is the issue reproduced only on specific types of X201, or CPUs, or WiFi card models, or is it caused with interaction of all those factors? Or is it a driver/sw? Or all together?
