Wifi device problem

[Krzysztof Kołodziej]

Try reinstall drivers in win10. I had this problem with stock android.

Thanks Krzysztof,

I did download the x98 Pro driver pack from TT and ran install.bat. Some of the steps resulted in “Failed to install the driver on any of the devices on the system: No more data is available” but for instance the Wifi driver was (re)installed.

But this did not change the non presence of the device in device manager (even after restart).

Do you think that all of the drivers should be (and must be) installed in order to “repair” my wifi adapter?

Does anyone know an SW with that I could confirm if this issue with the Wifi device is HW related? If yes, do you think I can send it to the new Spanish Teclast base and claim guarantee?

Thanks,

Levente

Check in installed programs “realtek wireless lan driver”. If you have it, uninstall. After restart, install only wifi drivers and make restart. Are you make clean instalation Mirek’s Android?

Hi,

I confirm that I have the same problem with the WiFi in Windows and Android. I have a Teclast X98Pro chineese edition. I was very happy with my tablet, but suddenly yesterday the WiFi worked very bad. Any advice to solve it is appreciated.

Thank you,

Javier.

Hi all,

I faced the same problem, after enter the bios, this is how I solved, (it happens more than one time)

after enter the bios i have not wifi on windows then restart to android and same problem, solution was, on android, turn flight mode on, shutdown (important shutdown, not restart) and start on windows, then i get my wifi device back. then go to android and turn flight mode off, and there is, wifi is back.

Just sharing, my experience,

it worked for me, good luck 🙂

Hi,

Thank you Abraham, I try it. I think it is a hardware problem with the Wifi antenna. I made this test, I’ve put my tablet very close to my router, and the WiFi works well again. Some users reported this problem in other thread. I test this at my home and my parents home, so I think the problem could be related to the WiFi antenna.

By the way, I contacted to Teclast.es and they said they cannot support me because the tablet is chinnese version. I’m very dissapointed with that.

I answer again when I test what Abraham did.

Thank.

Unfortunately the Abraham’s solución doesn’t work to me. The WiFi of my Teclast doesn’t work propperly. Any other ideas?

I have the same issue with the wifi since I purchased it a month ago. This worked for me today.   I enabled the bluetooth and paired it with my phone.   I went under settings, networks, tethering and enabled bluetooth tethering.  Immediately the wifi worked.  I can turn the bluetooth off and it still has a signal.

Hello guys,

@Krzysztof: I uninstalled the wifi driver and reinstalled it using the inf file, but it is still not showing in any ways in device manager (no unknown device or anything). I think it doesn’t matter what I install until the hardware itself doesn’t show up in device manager

@Abraham: I never opened BIOS (do I need to connect a keyboard via OTG to do that?). Tried your steps without success.

@Joey Piedmont: Once I was able to connect my phone with the tablet via Bluetooth and used it as a BT modem. So I got some internet on my tablet but it was very slow. The wireless device didn’t show up. Now, that I reinstalled  a couple of times the full driver package (http://techtablets.com/wpfb-file/x98-pro_driver-win10-teclast-drivers-pack-rar/) and BT driver as well, the BT connection is dropped as soon as they are connected. So I’m stuck with that as well.

So what I think: The wifi card is not available as like hardware. The tablet got sometimes really hot while I was playing on it (don’t thin on any GPU stress game) and that heat somehow loosened the wifi card’s connection on the motherboard. Now I’m planning to take it apart and try to ‘reconnect’ the wifi card. Without wifi it’s a brick.

Thank you all for the advises.

If anyone has any other idea, let me know.

Cheers,

Levente

Hello Joy and folks,

Thank you for your help. With Bluetooth activated the WiFi works, but it drains the battery. You should try to put in airplane mode your cell, I bet the WiFi of your tablet don’t work.

This afternoon I’ve installed a new battery in my nexus 5 in a tech store and I asked about the problem of my tablet. They think it is a problem with the antenna. Probably it is the best solution. Next week I update you, since I think it is a hardware problem.

Cheers,

  Javier.

Hi all

I came here because I too have the same WIFI problem. It can work for days or weeks and then all the sudden: gone. No WIFI adapter available (gone from devicemanager) or it is there but has a red cross so its not working. Sometimes disable/enable in devicemanager worked.

I tried driverbooster, was a tip from somebody on the forum. It says the WIFI driver is very old (may 2015…) and when it tries to update it then it goes wrong and gone is my driver / wifi adapter again…

I now am trying the tip I got in this post of switch to Airplane mode in Android. I keep you posted.

A little tip from myself. I cloned the entire tablet, all partitions using Macrium Reflect free version. You can try all you want with the WIFI driver it does NOT work but restore the tablet with Macrium is a 20minute job. In Macrium you make a BOOT disk. So you connect to the OTG connector a HUB and connect a keyboard, mouse, USBdisk with your backup image and USB disk with the Macrium boot partition. Reboot the tablet, press F8…F10 I dont now which one exactly. Until it shows the boot menu and here I choose to boot from USB. Then it opens Macrium, in there I choose the backup image and I choose restore. Done and working.

I know its only a workaround but its the best/fastest I have for any problem with these damn chinese tablets. Just go back to a working state with Macrium

Thanks Dennis, I’ll give it a try.

Had the same problem, But could solve it.

1. Go to Device Manager and then Disable “realtek rtl8723bs 802.11n sdio wireless LAN driver” (right click on the driver  and then “Disable” in contect menu). After that enable it.
2. After the device have no warning icons against the driver, goto Network Adapters settings (Windows Settings->Network and Internet->Network Connections) you should see there WLAN (with red cross – means it doesn’t work). Again Disable it and Enable it again. That should fix entire problem.
