unable to connect macbook pro (A2141) to wifi to complete the macOS installation

MacBookPro (A2141) is an office machine that was previously working. We cannot recall what macOS version it had before. It was reformatted for reuse by another individual. However, it is unable to connect to the wifi. Upon selecting the access point and putting in the wifi password, the process indicator right next to the password field is just continuously rotating. We let it run for >20 minutes but it didn't progress from there. We eventually cancelled the connection process and tried another wifi and got the same result.

Both wifis are known to be working for other Macs and Windows-based machines.

To get OS X installed on the Mac, you can create a bootable installer on another Mac (with working Wi-Fi).

Model A2141 is a 16" 2019 model, it can run the latest version of macOS (Sonoma)

It can also run any older version up to (and including) macOS Catalina (10.15)

If you have problems with using Internet Recovery Mode, then you may need to perform a DFU firmware Revive or even a Restore. I don't know if it will help if the process is failing at connecting to WiFi, but it cannot hurt if you cannot boot the laptop normally.

To download operating systems it is always best to do so via a wired connection as Wi-Fi is too slow and corruption of the file being downloaded often occurs. Since that may not be possible, as suggested, try using a disk with an installer on it.
