I'm trying to use the built-in wifi on my pi. I upgraded the OS on my Raspberry pi 3 B from Jessie to Buster. Since the upgrade, I haven't been able to ping my pi. I noticed that
ip link showed
DORMANT so I turned off power management using
iwconfig. However, while
iwconfig is showing that power management is off right now,
ip link is still showing that
dmesg also confirms on
reboot that power management is disabled.
On the Pi, I have internet access and can ping sites. What I'm attempting to do is SSH into my pi from my desktop.
Update with info from comment:
To upgrade I turned off my Pi, formatted the SD card on my desktop, and imaged the Buster image to the SD card.
I bought a USB wireless adapter (Panda wireless N plug & play, rt2800usb). The Raspberry PI recognized it and was able to bring up the interface, but this interface was also stuck in
DORMANT with the same conditions as the onboard wireless (Can ping external sites but it can't be pinged from devices on my home network). I also turned off power management for the new device (wlan1) but the link remains in
