Macbook pro wifi signal receiving very weak
I picked up my Macbook Pro from the Apple store yesterday for a display replacement and as I was trying to use my laptop for homework I realized that there were almost no nearby wifi networks. Only my home wifi was available and it was one bar. I tried connecting to it but it keeps having a connection issue. The only way I can use the wifi is if my Macbook is literally 1 foot away from the router and it connects (still extremely slow). I know that the router is not the problem, the wifi works fine on my phone and my Macbook Air. My laptop is covered under warranty since it just got repaired, but it’s disappointing that this would be the third time in 1 year i had to get service. Are there any correlations between the display case replacement and the wifi? How can i fix this? (fyi i already tried safe booting, and factory resseting the entire laptop)
