We recently bought our CEO a Latitude 7490. He works from home once a week. When he uses it at home on his wireless, his download speeds are atrocious. He's lucky to get 0.03Mbps down/10Mbps up. All other computers/devices at his home download at regular speeds 100Mbps down/10Mbps up.

Windows was not updating anything at the time. 

When I test his wireless here at work, he gets 47Mbps down/47Mbps up. We've got 50 meg fiber here.

I asked him if the laptop was in sleep mode when he brought it home. Not every time. He's even tried restarting his computer. Still lousy download speeds. 

I checked the site and found there were no updates for his Intel 8265 wireless adapter.
