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.

Hey Mirek, guys,

My built in WiFi is not working anymore so I bought a Wifi dongle (RTL8188EU).

In Win10 it works automatically as expected, but I don’t know how to make it work in Android. I have Mirek’s v2 ROM installed.

Mirek, could you please tell me what chipsets’ drivers are included if your rom? Would it be possible to include it in the next version?

I’ve found some RTL8188EU drivers for linux/android but I’m rather a windows guy, don’t know where/how to include the drivers and how to force android to use the new Wifi instead of the built in.

Thanks,

Levente

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

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
