Onda Xiaoma 21

Recommended Posts

Hi guys I got my Onda Xiaoma 21 in March of this year, unfortunately, the built in wifi (Intel 3165) has quit working about 1.5 months back. I’m wondering if any one else is facing this problem? The retailer I bought it from (China-based) provided a few suggestions to see if the device was disabled but I did everything he said and it still does not work. After that he just stopped responding to my request for return for servicing.

The wifi chip is built in and cannot be replaced. Under “Network Properties” in Win 10 the WiFi shows up as “Intel (R) Dual Band Wireless – AC 3165” and the status is “Not Present”. I suspect the root cause is that one time I shut the lid and put it in my laptop bag, but on taking it out a couple of hours later found that it had not hibernated as it should and was quite warm to the touch.

The  I’ve tried the following to no avail;

  1.  Services.msc > Wired Config + WLAN Autoconfig — Both running
  2. Installing the Intel drivers direct from the Intel website
  3. Restoring to an earlier restore point
  4. Resetting Win 10 (OS only) but this did not succeed there was an issue preventing it from completing (issue unknown)
  5. Looking for the Wifi setting on UEFI but I can’t seem to find it.

I’m at my wit’s end and currently am using a USB Wifi adaptor but it’s not ideal because of the slower speed and lack of dual band (5GHz not available). I’m pretty sure it is draining my battery faster than the on-board wifi too.

Recently I noticed that I had an unrecognised device in my Control Panel BCM2EA8 which I found to be a Broadcom device. After downloading some drivers, the device updated to "Broadcom Serial Bus Driver over UART Bus Enumerator", however the device shows an issue "This device cannot start. (Code 10)". Is this related to the WiFi issue?

Any suggestions on what I should do? Any help will be much appreciated!
