Windows 10: Wifi on Sony VAIO - adapter randomly stopped working

Hi all,

Hoping someone can help me as I'm a bit lost with this one.

A friend whos laptop I've done some maintenance on has given me another of his friends to do much the same - including upgrade to an SSD and add more RAM. It's a Sony Vaio (VPCEB4J0E). The laptop was described as "painfully slow" and it's not far from the truth.

It was also woefully out of date - still running Windows 10 1511 (2015) and Malwarebytes found 159 detections. So I got to work on updating Windows to the latest 20H2 and doing things such as disk cleanup, defragging etc as well as reducing the ridiculous amount of startup apps (it's currently got 3GB RAM as the RAM isn't arriving until tomorrow) I wanted to get everything cleaned up and updated before cloning to the SSD.

So after installing Windows 20H2, at this point WIFI still working fine.

After this I ran Windows Update again to get the latest cumulative updates etc since the release of 20H2, and these installed, laptop restarted - again, at this point, WIFI still working fine.

I decided to run another scan in MalwareBytes, just to make sure everything was clean. I also removed AVG with the intention of reverting to Windows Defender. At this point still the WIFI was working fine. Malwarebytes found something in a downloads folder - I think it was a copy of Utorrent, which it flagged, but it wouldn't have been running or anything as it was an installer, so I removed this, and it asked me to restart the PC.

I restarted and now WIFI is not working at all. The adapter shows fine in Device Manager, with no issues. And when I click on the globe icon in the system tray (globe with an X on it) it doesn't show me active WIFI connections to connect to, it just says something about turning WIFI back on either "Manually", "In 1 day" etc. I ran the network troubleshooter and it says the WIFI radio is OFF and to use function buttons on the laptop to turn it back on. This is determined by a switch on the front side of the laptop - however, I haven't touched this switch at all, and it's already in the on position.

Also before all this there was a green active LED next to that WIFI switch on the front. Now it's off completely - although it does come on during the Windows boot process, and then goes off again once the login screen appears.

I'm totally baffled. I can't see anything untoward in Event Viewer. The adapter is fully enabled and apparently working fine. It's using the same driver as before. I'm lost.

Any ideas with this one?

Thanks

:)

 

Wifi adapter randomly stops.

Hello!,

As the title suggests, my wifi card (Qualcomm Atheros QCA 9377) randomly stops working. It is showing a message on device manager saying something like "Windows has stopped this device because it has reported problems." This only started happening after
updating to Windows 10 1809 update. I can fix the problem by disabling and re-enabling the adapter but seriously, who wants doing that everytime it happens? Can someone give me suggestions on how to fix it permanently?

 

Windows 10 Driver Updates for Sony VAIO Still Nowhere to Be Found


For my case (Sony VAIO Tap 11)... it is there in the list of models.

... but it turns out i don't need that upgrade 'driver' anyway. The special 'upgrade' mode did nothing to my machine prior to the actual upgrade, and after completing the upgrade it merely installed one single update (to Sony Control Center I believe) that can be downloaded anyway from Sony's website. Working like a charm now running on Win10 (except for a few Intel display driver problems which are not specific to VAIO the way I understand it)

 

I have a sony vaio and it says my vaio is off most stuff works but my list are all messed up it is sony vaio svl 24125 cxb

Sony Vaio is the Brand Name of the laptop, not the operating system.

"it says my vaio is off most stuff works but my list are all messed" doesn't make sense.

How is your Vaio off?
