Question Laptop only able to detect wifi further away when connected to a nearby wifi

[ys98]

My Lenovo Y520 isn't able to detect my home wifi (further away) when I am in my room unless I am connected to my mobile hotspot. After connecting to my mobile hotspot, all wifi networks further away will show up and is able connect to them for about 10-20 minutes before it loses them out again.

My external wifi adapter does not have this issue.

What I have tried:

• Updating driver
• Reinstalling driver

I have the exact same thing with my ultra low end notebook. I basically have to use the usb wifi adapter, and it works GREAT, the built in one is really bad and not fast either.
