Windows 10: Windows 10: Long WiFi Connection Initialization Times at Boot

To start, I've read many posts referring to this issue but as of yet, I've found no hard answers. So, I'm asking my own to see if maybe anyone has stumbled across anything new.Somewhat recently, we started having issues with laptops not immediately connecting to WiFi on start up. This occurs across multiple Dell models as well as some HP. Machine will boot, arrive at the lock screen, and nothing. Generally, it takes several minutes to finally connect on its own. To note, you can manually connect pretty soon after startup and is usually works fine. Sometimes it doesn't, but not a good enough r

Very long boot-times with DVD-drive?

Hi guys,

got a lil problem here. My machine takes very long to boot. It sits @ that windows-knight-rider screen and the blue line is crossing about 10-12 times before anything happens. Yesterday i had to disconnect my DVD to connect my reserve hdd and see... it boots after
3 or 4 times of that line passing. Is that coz i got a bad driver or bad firmware there....Don´t know if driver makes difference coz i think windows got 1 generic and it don´t affect my secondary DVD drive... any suggestions?

 

Can't connect to wifi after Windows Update

I tried all the steps you suggested, but those steps did not fix it.

Then I tried the clean boot for, by disabling everything in startup and disabling all services in system configuration. Upon restarting, my wifi features actually worked. I could connect to wifi, like I was supposed to.

But then when I followed the steps listed to isolate the service that may be causing the problem, by systematically starting the services and restarting each time, to find out which one results in disabling my wifi connection, my wifi connection hasn't returned,
even after disabling every service again. I have tried repeatedly to recreate the conditions that resulted in my wifi connection working that first time that I tried the clean boot, but I have been unable to do so. Now, even with all services disabled, it
still can't connect to wifi. I don't know why it worked that one time, but hasn't worked since, even though I've tried disabling all services again, just like I did that first time.
