Didn't expect to have WiFi issues with a new laptop...

This ThinkPad replaces a 2013 Toshiba laptop as my home office computer. I have WiFi in the one story house and my office is at one end of the house. I never had reception issues with the WiFi until cranking up the new computer. The signal goes in and out. Uploads and downloads are interrupted. Got an range extender and that still doesn't solve the problem. Reset my network adapter settings, got a new WiFi modem and still have the problem. I would think WiFi technology would improve over time. I guess I am wrong. Anyone else have this issue?
