As the laptop boots, the ethernet lights are on identifyingĪ connection, but as Windows 10 loads, the ethernet lights on both the router and laptop turn off. I have tried various cable combinations between the 4 router ports and testing various cables. One of the two Dell laptops will not connect the gateway once Windows 10 loads. I have a rented Comcast gateway than is less than 2 weeks old. The configuration is identical in both machines. I have a two 2009 vintage Dell laptops, both running Windows 10.
