Updating your wireless network card drivers
But, as soon as I shut the laptop down, and powered it back up the next time, it just would not connect to the same wifi. Everytime it's the same message - "Can't connect to this network".
The only way I got around this until now, was to manually reboot the wifi router, and as soon as the router would come back up, Windows 10 would instantly get connected.
Update and repair your drivers safely and automatically with the latest version of Driver Detective.
The award winning software will download and update problematic drivers for your computer and external devices such as scanners, printers, cameras, hard drives, DVD, monitor, wireless and other hardware.
Your wireless card should be listed, and most likely a LAN adapter as well.
Alternately, you can open the Network and Sharing Center in the Control Panel, and then click on "Manage Network Connections." Find your wireless connection in the list and right-click it, then select "Status." Under the Status menu, click "Details." This will produce a list of information about your Internet connection, including your wireless card.
I looked at this No internet connection after upgrade to Windows 10 question, and tried to check my "advanced adapter options", but it all seemed correct (attaching pictures below).
If you have a static IP, there'll be a selection of numbers in the format of "##.##.##.##" in the text boxes.In addition to updating your Windows 7, XP and Vista drivers, the software will also download and update your drivers for external devices such as scanners, printers, cameras, hard drives, DVD, video, graphics, USB, wireless and other hardware devices.Once a free driver scan has identified software which is out of date, it will search a comprehensive database of official drivers and download the latest updates for each component.Wireless connected back up immediately after doing so. Unfortunatly removing this driver didn't resolve my problem.I have the same problem with the same network adapter. EDIT: For me it helped to reset router (just unplug and plug it again) I think it might be an issue with router.
I have no idea how/why this worked, but while it did work fine up until sometime back, I can't keep doing this anymore.
