I have a notebook computer I frequently refer to for various things. It is on wi-fi and I have it set to sleep when the lid is closed. Until recently this has always worked perfectly. If I want to check something on-line, I just open the lid, tap the touchpad and I’m good to go.

The other day a Win 10 update was forced on me. Since then, I have trouble connecting to the wi-fi when waking the notebook. Sometimes it works normally like it used to, but most of the time it says I don’t have an Internet connection and I have to reconnect manually by clicking on the wi-fi icon. Sometimes I have to turn it off and on to get it to reconnect, and it can take quite a long time searching before it finds the network.

Has anyone else encountered this issue? Is there any way to get Windows to save the connection information so it doesn’t have to search for it again each time. I never had this problem until the last update. Previously the wi-fi connection would come on almost immediately after the computer awakened. Now I have to fiddle with it all the time. Why do updates always seem to break something? It gets very tiresome.

Check what updates have installed by date, pick anything that looks related to wifi or network and uninstall it, reboot and see if the problem persists.

Otherwise, see if there is an update for your Wifi Driver from the manufacturer's website or chipset manufacturer.

Have you checked Device Manager wireless adapter power management? If it is set to allow comp to sleep it, try unticking that setting.

I have gone through all the steps I could find for dealing with this issue, including unticking power management, but nothing has made a difference. However, there may be something else at play here (isn't there always?). I notice I am getting the same problem on another laptop running Win 7, which kind of implies that the Win 10 update isn't at fault for once. Coincidentally, I changed the wi-fi at the same time the update happened, so it may have to do with that. I swapped it back with the original unit, but still had the same problem, which was why I concluded it must be the update. Now I don't know what the hell is going on. Nothing unusual there but I am going to put back the original AP and try it on both computers for a longer period to see if I can make some sense out of this.

To eliminate the Update casing the issue you could uninstall the update you believe is causing the issue.

Here is a crazy notion, lets give peace a chance.

Yeah, I could if bloody Windows wasn't such an inconsistent mess. If I look at the updates I get a list of names including some KB updates. If I then switch to uninstall, I get a different list that doesn't coincide at all with the first one. The first one does mention a wi-fi update. There is no trace of that to be found in the second, and no reference to anything that seems remotely connected to wi-fi. Most of it is just buried in a couple of 'cumulative' updates that don't bother to specify the contents.

I have a laptop (HP Spectre 360) which does this fairly frequently, and has done so for the last year or more, It's intermittent, and weirdly a reboot seems to put it right for some time. I've not had the time to look too carefully into this, but have also checked the obvious like wifi adapter sleep settings. Clearly this is no use to you apart from it lets you know you're not alone!

Windows 10, power save causes this type of problem.
Microsofts 'fixes' only seem to make it worse/more widespread. (A bit like the Win98 shutdown issue, they could never ever fix properly.)

You will need to go down to detailed level & disable all power save features related to the PCI Express & USB power settings.

If you get them all - this should fix it

(Until Microsoft push out another power management related update......)

It looks like you may be spot on. I changed every power setting I could find to maximum performance and it now appears to be working correctly. I feel it is still too soon to say for certain, because with Windows things that seem fixed often turn out not to be, but so far this is holding. If it continues to after a couple more days, I will conclude that it really is fixed.

The new wi-fi may also be a factor, because it now takes longer to come on than it did before, but the difference is only a matter of a second or two before it starts responding.
