Weak wifi signal after battery change

Hello. I changed the battery on my S7 & since then I have experienced a very weak wifi connection. I can no longer connect to the wifi in different rooms of my home. I have looked at the wifi antenna & everything looks fine. I did accidently pierce the old battery when I was taking it out & it got  very hot before I was able to remove it.  Any idea?

You’ve detatched the wifi antenna lead from the motherboard. The antenna is built into the top (black/brown) plastic shroud on the S7. You’ll have to open the phone again, and make sure it has no signs of damage, and is properly attached to the logic board.
