Hi,
I had Wifi issues, too at my X98 plus A6C9. They revealed e.g. by frequent connection drops or poor connection bandwith to my router (e.g. 1 MBit/s).
Accidentally today I opened in Windows 10 the device manager, right-clicked in the device tree on Firmware and then on System Firmware. After that in the context menu I clicked on Update Driver. Unexpectedly the message showed that the driver (System Firmware) has been updated and I should restart Windows.
During reboot it showed, that the System Firmware (Bios?) was being updated…
Now the name of the entry in the Device Manager below Firmware has changed from System Firmware to Teclast System Firmware.
By the way I noticed that the Wifi connection got much better (e.g. 72 MBit/s) with no connection interrupts.
Anyway I’m wondering why I had to trigger the update manually as I have configured Windows to update all drivers automatically..
