Windows 10


When I run diagnostics I get these messages:
The connection between your access point, router, or cable modem and the internet is broken-Detected.
and
The default gateway is not available-fixed.

If I start the computer again the wifi is connected for another 3-5 minutes and quits

The device says: 300m wireless USB adaptor with a blue square and a lower case "n" on it

Is the device bad?

Thanks
