network adapter?

doesn't Wanna work, I'm on a windows 10 Lenovo, trying to connect. it simply just won't pick up my wifi, then when it does it says "cannot connect to network" the few times it does connect. It's very weak, note that all my other devices are perfectly fine, when I troubleshoot. It says I need to connect a Ethernet cable, when going to problems found it says "network capable is not properly plugged in or may be broken."
