Q: Lenovo Yoga 2 Pro, WiFi and right USB not working

Hello!Recently I've changed the thermal compound on the CPU of my Lenovo Yoga 2 pro. Before the change there were no problems. But now I have 2:- Wifi isn't working. Network adapter isn't detected by the laptop. It just doesn't show up. Funny thing is that bluetooth works!- Right USB isn't working, no idea why.Everything else seems okay. Any solutions? Tips? Thanks in advance. I'm running Windows 10.

Hey guys,  I bought this Lenovo Thinkpad Yoga 14 about a month ago, and have had no problems with it until about 3 days ago when the wifi internet got really slow and would cut out with in a minute or two of working. During this time, any time I open the notebook and connect to wifi all other devices in the house won't get internet. I've tried browsing through this forum, but the solutions that seemed to work for others have not worked for me. If anyone has experienced this or knows of a solution please let me know. Thank you!

Here is my situation (read carefully): I never had wifi problems with my 1st gen Lenovo Yoga running Windows 8 64-bit. Always super fast wifi and 5 bars on the icon. One morning, I couldn't connect to my home wifi (unidentified network), but I had no problem on my Android phone. I called my Internet provider and they "separated" the 2.4GHz channel (made for further distances, but slower) and the 5GHz channel (for shorter distances, faster). From then on, I could see the 2.4GHz on my laptop, but not connect to it and I couldn't see the 5GHz.On my phone, I could see both. As I obviously suspected a problem with the Realtek RTL8723A network adapter on my laptop, I reinstalled the driver, which partly solved the problem, as I can now surf the Internet on the 2.4GHz, but still can't see the 5GHz.Plus, I only have 1 bar on the icon, even though I'm 2m from the router. Is there anything I could do to see both channels, just like on my phone, and be able to use the faster 5GHz channel? Thanks

Hello, The WiFi adapter is the Intel Dual Band wireless-ac 3160 and the drivers are from October 2017, the Device Manager is showing the network card as working without issues and nothing is reporting any problems, yet I am unable to simply turn the WiFi ON. The operating system is Windows 10 and I have tried the following: - enabling the WiFi interface using the command prompt (says it is already enabled)- trying older drivers for the Intel Dual Band wireless-ac 3160 (still will not turn ON)- opening the laptop and disconnecting the two wires from the WiFi module, then reconnecting (still no difference)- disabling and then re-enabling the Wireless in BIOS (no difference)- loading default settings in BIOS (no difference)- installing Windows 8.1 from scratch (same problem)- re-installing Windows 10 (same problem)- installed all of the Lenovo utilities and Companions I could find (still nothing)- windows troubleshooting simply tells me to switch the WiFi ON using either a hardware switch (which does not exist on this notebook) or the software switch using the keyboard - I press the F7 for airplane mode and it says that it goes into that mode, then pressed again and it simply goes back to WiFi which is turned OFF and showing the red X What is interesting is that when I booted TAILS from a USB drive the WiFi worked without issues, so this is obviously a software problem. Any suggestions?

Recently there was a Wifi Driver issue, which got resolved when the service guy came and replaced it, 6-8 weeks ago. After that my Wifi works fine but has a bit of a performance issue - It takes some time to identify Wifi Networks. If I switch on my bluetooth, the wifi performance degrades more, i.e. more time to identify network and the speeds of download/upload deteriorates a lot (A video in Youtube 720p quality is brought down to 144p).In addition it seems to take a lot of time for my bluetooth to identify a device. Does the Wifi and Bluetooth share the antennas? If so does this mean the antenna have a problem now?Is there a way to troubleshoot this? maybe by checking speed on Wifi and bluetooth.

Hi
 
I odn't have that model, but just in case what you can always try is to get the latest wireless driver, sometimes I have some issues with some older wifi drivers.
 
Check the support site and see if there is a newer driver for the wifi. Check your "WIndows Device Manager" and see the version of the driver you have installed for the wireless adapter.
 
I also like to test the wifi with different routers on some other networks just be sure that is not a local problem of my router too.
 
It is also good the check the maintenance manual of your model to see the cables and the antennas. I'm not sure if that is exactly your model, but it seems it was two antennas for the WAN network and 2 for the LAN. It does not specify anything about the bluetooth.

Hi Guys, I have a Lenovo Yoga 2 laptop. This is the second time I have had issues with the WiFi dropping out frequently.  The first time was when I first downloaded windows 10 - I downloaded a new driver from the Lenovo website and everything worked perfectly.  The last couple of months it has been playing up again. My phone and any other devices will be connected to the internet however my laptop will repeatedly disconnect from the internet, this happens a ridiculous amount of times everyday - and it's not just my home wifi! Im currently at my university library and it does the same thing. It just drops out randomly and says "not connected - no connects are available" I have to keep restarting my laptop for it to reconnect to the internet (I know that's probably not the best thing to do but it's the only thing that sometimes works). I've tried uninstalling and reinstalling the driver software, I've scanned for hardware changes and nothing comes up?? Has anyone got any ideas on anything else I could try?  Thank you all!

Hi, I bought a brand new Lenovo Yoga 910 series laptop, costing a fortune. Its not even 20 days since I bought this laptop, I am seeing the wifi adaptor losing the connection within 5 mins of usage. Whats worse, it causing my wifi router to jam as well, and all of my other devices loses connection. I have few other devices, including a lenovo thinkpad, where i never faced any issues till date.  After some research I found out that the wifi adaptor in the lenovo yoga is Qualcomm Atheros QCA61x4a  and it has lots of issues on Windows 10 and people are complaining on multiple forums about it since couple of years. Suprising that Lenovo nor Microsoft nor Qualcomm has not fixed it yet or I couldnt find a proper solution till now.  It is such a bad customer experience, that such a basic thing like wifi connectivity is not working properly on such a high end laptop. I feel I just made a bad decision of buying this waste device instead of a Mac book Pro. Hope someone from Lenovo fixes this for me or else I shall return this device.

Then I had restarted WiFi router and network showed Up, but as soon Yoga connected, same again no network. I googled for solution and I did uninstall EMC and Lenovo Utility but that did not resolved the problem. Then I had tried to uninstall all drivers and than download and install them again but still the problem is there. Wherever Yoga connects WiFi dies. I found that some routers recognize something like DDos attack and so I dissabled that option on routers but again problem is there.

It keeps dropping regularly even though tablet is within a feet distance from the WIFI router.In the WIFI menu the router name comes but if i select nothing happens and you can see that the tablet is not connected to any WIFI. The only way to temporarly solve the issue is to restart the tablet but that too lasts maybe 1 hr before the WIFI connection goes away. I saw in another thread of this community where it was suggested to do factory reset. I have done that too but the issue still exists. I have another PC and 2 mobiles which connects to the same router. So there is no problem with the router  Any suggestions how to fix?  Thanks.

Hi all. Nice to meet you. I have a Lenovo Yoga 720 and am noticing two issues.  First, whenever I am on Wifi, my connection will occasionally drop and restart. It is becoming a challenge especially during Skype calls and even simple tasks like browsing. My wifi appears to be OK because I have another PC and Mac that does not have any connectivity issues. Is there something I can do investigate and solve this issues?Moreover, I have connected my Microsoft Sculpt Mouse which had worked great on another PC's. While I can connect it with my Yoga, the connection frequently drops and takes a couple of seconds to re-establish itself. If anything, these issues have become a pain.

Hi, welcome to the forums.
 
Can you please post the full model number of your Thinkpad Yoga 14?
Are you using Windows 10?
 
I may suggest you first to try to update the Wifi drivers and maybe some other of the system driver of you Yoga.
Here are my general tips:
 
1) Try first Windows Update and update all the drivers and Patches
2) Try Lenovo System Update to get any new/missing drivers.
3) Try to install Lenovo Settings and Lenovo Companion from the Windows App Store, Lenovo Companion also has a "update driver search"
4) Sometimes all that software does not recognize some updated / missing driver. Check Lenovo's Support Site and search for your specific model drivers (use the full model number of your Thinkpad).
 
After that we can try a little bit more. For example I also like to test it on some other Wifi networks just to be sure it is not a compatibility issue with the Wifi Router.
 
Regards

Hello, I have a X1 Yoga 1st gen bought around 1 year back. It had a fan problem which finally solved only after a replacement of the fan. I received my laptop yesterday and since then the WiFi doesnt work anymore. It worked prefectly before I gave it for repair. It doesn't connect at all OR if I put it right next to the router, it picks up an extremely weak signal that is of no use. I have tried updating the drivers to the latest one (from Lenovo support website, ver 20.3). But this hasnt resolved the issue. Could you please tell me how to fix this? It is annoying to buy something worth $3000 that has all kinds of problems from the get go! First the fan and now the WiFi. Thanks!

Last year I had the laptop sent to Lenovo to replace my screen because my brightness would not change. Since then, the wifi adapter would "disappear*" randomly, though not often, sand I would have to reinstall the intel WLAN drivers to fix it. I though it wasn't going to be a problem. However, in the past two days, the wifi driver would disappear every time I turn on the laptop. Reinstallation did not bring it back and repairs did not work. I had to resort to using an external wireless adapter.The volume down button seems to be stuck down, not physically but more like it was "stickied".*disappear- the drivers would be missing, not disabled.

I have a Yoga 13 running Windows 8.1 that has recently stopped connecting to my home wireless network. All the latest Windows Updates are installed at this time.I have uninstalled the Realtek Network device and the related drivers, rebooted and tested without luck.This unit sees the networks and if I enter a wrong password, it asks for a re-entry of the correct password.  When the correct password is entered it says "Checking Network Requirements" then fails with "Can't connect to this network"None of the troubleshooting services have been successful.All my other devices connect without any issues. I am runniing a Netgear R8000 Nighthawk wireless router. What is odd is that this laptop will connect to my iPhone 6 hotspot without any issues. I suspected a windows update may be the cause so I downloaded drivers from Lenovo for the wireless adapter.  Uninstalled the current ones, rebooted, and then installed the Lenove supplied drivers.  Still no joy. Any other suggestions short of a reinstall of the OS? Cheers! Hawkeye007

This issue started recently, after months of it working fine. The internet just would randomly stop working. I would use the troubleshooting function, it would go through the process and connect to our network, but then when I tried to go to a website, it would say there was no internet. Eventually I was able to get an old Netgear USB Adapter to work. I have tried changing the power settings, removing the drivers in the device manager, and I have the latest wifi driver. I have read many of the help posts on other Yoga wifi issues. Is this a software issue or a hardware issue? Thanks for the help!

I've had my Lenovo Yoga 910 for a year and a half now and about a week or two after I got the laptop the standard usb 3.0 port (the type-A next to the headphone jack) stopped working properly. It still gives power to devices but cant transfer files, wether its my phone or any usb stick. It didnt really bother me because I had an adapter for the usb type-c. However, in about december last year the type-c port stopped working. I got it sent of, but for some reason it came back unfixed because they thought I had a problem with my trackpad instead of the ports and didnt have the time to get it sent back off. As I said, I dont really have the time to get it sent off for two weeks to be repaired and have gone thorugh every forum on the internet and none of the solutions work relating to the device manager, regedit and trying to find drivers online. I also can't find anythng spesific to this model so that also adds to my problem. Also, just a note that I have tried many diffrent devices through both ports and, I'm also sure that its a software issue not a hardware issue as the ports are clean and atleast the type-A charges my phone.  If anyone has any solutions please share because it has been driving me insane!

I recently downgraded from Windows 10 to a Windows 7 operating system. When I downgraded I needed to disable secure boot and disable OS Optimized settings in the BIOS in order to boot from the USB drive to install Windows 7. When I reinstalled Windows 7 I did a clean install, put in my Windows 7 Key and installed all the necessary drivers. However, it seems that my USB 3.0 ports are not working. On the flip side, when I plug in my phone or a thumb drive into the USB ports, these devices are recognized in the BIOS. Also, I looked in the device drivers and it seems that my USB drivers are installed. There is, however, an unknown device, which in the details tab reads:IUSB3\ROOT_HUB30&VID_8086&PID_9D2F&REV_0021&SID_504C17AAIUSB3\ROOT_HUB30&VID_8086&PID_9D2F&REV_0021IUSB3\ROOT_HUB30&VID_8086&PID_9D2F Attempted solutions: I tried to reset all BIOS settings back to factory settings but when I did that my OS would not start until I turned secure boot and OS Optimized Settings back off. Also I tried looking for drivers on the website but  could not find any to do with the USB 3.0 ports. Looking forward to any advice anyone can provide in me fixing this issues.

A:Lenovo Yoga S1 Fan not working

Does the fun work when you are inside of BIOS? If it doesnt work, I think you have hardware problem.And can you say, after which manipulations you find this problem? How old is your laptop? Maybe it will be neccecary to clean  the fun?

I recently downgraded from Windows 10 to a Windows 7 operating system. When I downgraded I needed to disable secure boot and disable OS Optimized settings in the BIOS in order to boot from the USB drive to install Windows 7. When I reinstalled Windows 7 I did a clean install, put in my Windows 7 Key and installed all the necessary drivers. However, it seems that my USB 3.0 ports are not working. On the flip side, when I plug in my phone or a thumb drive into the USB ports, these devices are recognized in the BIOS. Also, I looked in the device drivers and it seems that my USB drivers are installed. There is, however, an unknown device, which in the details tab reads:IUSB3\ROOT_HUB30&VID_8086&PID_9D2F&REV_0021&SID_504C17AAIUSB3\ROOT_HUB30&VID_8086&PID_9D2F&REV_0021IUSB3\ROOT_HUB30&VID_8086&PID_9D2F Attempted solutions: I tried to reset all BIOS settings back to factory settings but when I did that my OS would not start until I turned secure boot and OS Optimized Settings back off. Also I tried looking for drivers on the website but  could not find any to do with the USB 3.0 ports. Looking forward to any advice anyone can provide in me fixing this issues.

USB 3.0 wasn't supported back then. Doesn't work with Win 7. You have to stick to the 2.0 ports. Return to the original installed OS or Windows 10 for it to work.

 We use Yoga Pro 3 computers for work, so I have several and this problem is the same on 3 of them (which leads me to rule out a hardware issue): the wifi adapter just went missing one night, seemingly after the latest routine windows 10 update.  Bluetooth is still there, but no wifi.  If I go into the device managers, I see a bunch of 'wan miniport' artifacts, but no actual wifi adapater.  I've rolled back the update (multiple udpates, for tha matter), played around in BIOS, I've tried intsalling the network adapter drivers manually, and on one computer, I even did a factory reset.  Nothing works.  Certainly a windows update can't damage the wifi card itself.  Anyone have any ideas?  No network connection makes these computers expensive paperweights.  And since they're employee computers, time is critical.  I'm giong to have to guy buy new computers this week if I can't resolve this.
