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)

Correlation:

The only correlation could be the replacement in hardware. When this occurs, sometimes you need to reset the SMC and NVRAM (See below).


Troubleshooting Show Mac Wi-Fi:

A few thoughts to try...

I. Clear the Temporary Internet Files:


II. Restart your Router:

  1. Power: off the router
  2. Wait: 30 seconds
  3. Power: It back on


III. Boot in Safe Mode:

[Hold Down: shift key, upon boot], In Safe ModeLogin Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally, attempting another update install.


IV. Try a New Admin User:

What happens when you create a new administrator user, and log into it? Do you still get this error? If not, then it is likely an error with the current user. If so, then it is likely an error with your Mac.


V. Reset your SMC and your NVRAM:

Sometimes changes (i.e. Installations) are made to the system and then settings (i.e. Networking) become corrupted, technically. So, reset both on your Mac. So, reset the SMC and reset the NVRAM or PRAM. It might take three tries. to fix this. So, be certain you have the time to do so.
