Windows 10 devices unable to access internet for a long time after start up
We are having problems with our router and our Windows 10 computers. When the computer starts or wakes up it can take up to several minutes to be able to reach the internet. During this time I can ping the router and access other devices on the network using SSH, but not reach the internet.
I have tried all the guides I have found related to WiFi connectivity issues and Windows 10 such as: updating drivers, turning off the feature which lets Windows 10 shut off the WiFi-device, disabling the firewall, changing DNS, changing power settings, disabling autostarted applications, but nothing seems to improve the situation. If connected directly to the router with a cable the laptops connect right away, so the issue seems only to happen using WiFi.
Our android and Ubuntu devices do not have this issue, they connect immediately after starting up.
We have tested our laptops running Windows 10 at my parent-in-laws who has an Asus router, there we don't have this issue.
Any ideas what can cause this?
