If you watch this video 3, or the picture below, you will see the WiFi card.

It will also cost a lot less time than trying to figure out all the software stuff you can try. It's not expensive, and it's not very hard to replace. Every time it breaks for a few seconds, it's broken for the rest of the session. Therefore, a WiFi card that works 99% of the time, actually seems quite broken. When you reboot, the adapter has another chance to work. However, if it fails at a certain point in time, the OS will think it's failed for the remainder of that session. It doesn't necessarily fail in a binary way. Intermittent functioning of a device such as a WiFi adapter is not unheard of when its hardware is failing.
Also, I have had seemingly the exact same issue (sometimes it would work days on end, but intervals kept getting shorter), and replacing the WiFi adapter fixed everything permanently. Therefore, the source of the problem must be hardware. Also, removing the power cord does not change anything to the software, but has some influence on the hardware. If it wasn't a hardware problem, the WiFi card would've probably immediately worked in Ubuntu. If it works under Ubuntu it must be a software issue, and if it doesn't, it must be a hardware issue. It takes little time to make one, and will be much easier than trying to troubleshoot everything that can go wrong in Windows. That way, you can very easily rule out any software issues. I always check this type of problem with a bootable Linux usb stick. I suspect a hardware problem with the card. I would still like to know possible reasons on this. Unfortunately, 10 seconds didn't work for, but a few hours did!

I have read a similar fix working for some user, i.e., switching off the PC and removing the power cord for 10 seconds did the job for them. Losing all hope, and I was quite convinced that this is a hardware issue, I switched off the PC for a few hours, even removed the power cord and after that, I booted into Ubuntu again, and there it was working again. And the wifi did NOT connect, in fact it showed wifi adapter not found in settings! So I tried the method of running it in a different OS, and I tried it both on my dual boot system (On Ubuntu) and a bootable usb drive. But now it seems to me that a software issue is more likely. I assumed the issue was closely related to power.

Checking if the hardware is detected or not using 3rd party applications (neither WiFi adapter nor Bluetooth adapter were detected.Reset WINSOCK entries to installation defaults: netsh winsock reset catalog.Reset TCP/IP stack to installation defaults: netsh int ip reset reset.log.I also tried other suggested solutions such as: I would like a more fundamental solution that I can understand.

I have also seen some other users having a similar problem and some recommended bizarre solutions such as 'Turning off the PC and removing the power cord for 10 seconds' or leave it as it is and Windows will fix it, to updating certain drivers (Since this one was for Intel Adapter, I didn't apply it). Qualcomm Atheros QCA61x4A Wireless Network Adapter "Miniport Qualcomm Atheros QCA61x4A Wireless Network Adapter,, had event Fatal error: The miniport has failed a power transition to operational power I found a power log (see below) that corresponds to my issue, and occurred right after the computer came out of sleep mode. I also installed a related Windows update: Qualcomm Incorporated - Ports - 12:00:00 AM - 2.1.2.2.įor further diagnosis, I check Windows Event Viewer and searched for logs around the time of the incident. I tried various ways to fix it, including installing official drivers from the manufacturer's website and updating the BIOS. However, the Bluetooth adapter wont show in Device Manager either, instead it shows "Bluetooth Device(Personal Area Network)".
The adapter has both WiFi and Bluetooth modules in it. This time I was unable to find the WiFi adapter in the device manager's network adapter section. This has happened earlier and I used to do this: I went to the device manager and in the network adapter section, would choose Qualcomm Atheros Wireless and I would disable and enable it. I cannot find it in the list of available networks. Right around when the battery was around 10-20%, I decided to put it on sleep for a few hours until I got the power supply.Īfter a few hours, I opened the system and the WiFi was gone. My WiFi was working fine recently, I had no power supply so it was running low on battery. The wireless adapter is a Qualcomm Atheros QCA61x4A Wireless Network Adapter.
