I have a Pi3 and PiZero. When I open up a Terminal window in Windows and SSH into the Pi4, the text is not color coded like on my Pi3 and PiZ. It appears that the .bashrc files are the same per a different post. What can be different?
It appears that there is not a real way to diagnose this issue. After changing the color prompts per above in both the pi directory and another, nothing seemed to work.
Slow wifi and not able to connect continued to plague me so I thought there was a hw issue starting to develop. Long story short, I dnloaded the latest release and reloaded it. Color works and Wifi is stable and fast.
