Raspberry PI 4+ defective 2.4G wi-fi

ORDER #2485313-3881220049
I bought a Raspberry Pi 4 from you and it appears the 2.4Ghz Wi-Fi is defective. I have tried the latest Pi OS and Ubuntu 64x Desktop and both OS's the 2.4Ghz wi-fi doesn't connect (or stay connected) The 5Ghz works fine though. Not interested in returning the Pi for replacement but would consider a small credit to buy a Pi Wi-Fi dongle from you.

Lots of things can cause wifi issues. Is this your only Pi? Does this Pi behave like this with another 2.4ghz network?

Do these successfully connect to the same 2.4ghz network you are trying to connect the Pi 4 to?

yes I have no trouble connecting any Pi to my 2.4Ghz network. Except for this Pi4 I bought from Adafruit and it either won't connect or connects and drops the connection. I have tried Ubuntu desktop 64x and Raspi OS 32x and the results are different but it still doesn't connect.

It could be power related. What are you using to power the Pi 4?
