Hi all,

I have a custom built gaming PC with a ASUS z270e motherboard with a Qualcomm Atheros QCA61x4A network adapter on board. It has run swimmingly for 2 years. Then 2 weeks ago I suddenly began having large lag spikes in games (ping in the thousands) and disconnects from the internet generally. Nobody else on my network was receiving these and it was happening with such frequency at random times of offpeak usage that I concluded it must be the network adapter.

Low and behold I check the device and the "Events" log under Properties. On 2/26/19 there were several events logged:

Information 2/26/2019 12:13:01 AM Kernel-PnP 410 None
Information 2/26/2019 12:12:59 AM UserPnp 20001 (7005)
Information 2/26/2019 12:12:59 AM Kernel-PnP 400 None
Information 2/26/2019 12:12:59 AM Kernel-PnP 440 None
Information 2/26/2019 12:12:29 AM Kernel-PnP 430 None
Information 2/26/2019 12:12:25 AM Kernel-PnP 430 None

This almost exactly coincides with my internet troubles. Down to the day. I think these are driver events right?

There are details within each event but I am not sure if those logs are safe to post (i.e. whether they contain personal information) and if you guys think that its safe I can follow up with those.

I looked around for similar posts discussing the 2/26 update and found nothing. I looked on my system for a previous set of drivers and I could not locate some to roll back to. I did not initiate the 2/26 driver update so I do not know if a Windows rollback would fix this permanently.

This issue is so bad that it renders the internet unusable on my computer for any meaningful period of time for hours.

Any thoughts on how to fix this? Or if you think this is what is causing it? I am going to go buy an external network adapter shortly and test whether I have the same issues on a different network card.

I am also running Windows 10 Pro for added information.

Thanks in advance!!

Jim
