No internet access after reboot on laptop - disable/enable restores it

[michaeljc70]

I changed my network going from using a Comcast modem/router to using a separate router. Everything works fine on 4 computers, 2 phones and 2 tablets.

On one Win10 laptop, it connects to the network after rebooting, but I don't have internet. If I go to the adapter and disable it and enable it, it is fine. It is annoying to do that though. Any ideas what could be causing this?

I haven't let it sit a long time (more than 3 minutes), so I don't know if it would ever get internet on its own. When I disable and enable the adapter, it is almost instant.

Check for a firmware update on the router and a BIOS and wifi driver upgrade for the laptop. I has seen these issues and they tend to be caused by the network card and router not talking to each other and getting a DHCP address. I am thinking if you do an ipconfig /all command on the computer when it has the issues, you will see the IP on the device is 169.x.x.x instead of what it should be.

Thanks. I will check the BIOS and wifi driver. I upgraded the router firmware last week. I do see the IP is 169.x.x.x which was odd since the router is 10.0.0.1.

It's not odd, it just means that the computer is not getting a DHCP address from the router. I did a lot of searching when I ran into this issue one not just two computers but also a tablet, the fix was a combination of using a higher end network card and replacing the router firmware with a open source one (I have an ASUS router), after a few days, the issue went away.
