If so, then possible the internal wifi (assumed) is failing. Tried it with a USB wifi device?
I have two laptops, a fairly new Toshiba AMD A10, 1TB HDD, 12GB RAM running Insider Program Windows 10 pro and an older ASUS laptop with lower specs running Windows 10 Home edition both running wireless on my home network. The ASUS download speed is about 29 MBPS. The Satellite broadband speed is about 2.8 MBPS - 10% of the other laptop broadband speed. Can't figure out where the problem is. Any suggestions will be greatly appreciated.
