DeathAdder V2 Pro USB Receiver vs Weak WIFI connection

I have a ZTE F660 wireless router. Although I have a weak WIFI signal on our 2nd floor but it does not disconnects me. Funny thing is, when I use my USB receiver for my DeathAdder V2 Pro it somehow disturbs my connection and now I am getting disconnection.

By Elimination tshooting, I removed the receiver from my laptop and WIFI gets working properly again. I have been using the mouse via receiver for 2 days after buying the mouse and I get the constant disconnection. It's now 2 days that I am using the mouse via bluewooth/usb cable and haven't encounter the WIFI issue on the same spot where encounter the disconnection using the receiver.

Will try to set up a place on which I have a strong WIFI and use the receiver again and see if I encounter the disconnection.

Are there anyone also experiencing this issue? Hit me put maybe we can do more testing although I am not an expert with networking.
