Strange Issue with WiFi on Raspberry Pi 3B/3B+ on Aruba Access Point


#1

I am having a strange issue when connecting my Raspberry Pi 3Bx devices to my Aruba Access Point.

  • Access point works with other devices (zerow, macbook, iphone)
  • RPI3 works with other Access Points

It ONLY fails when using the Aruba AP with the RPI3.

I am unsure even how to debug this, any help would be much appreciated.

UDPATE: I just unplugged the wired connection and then the ping through the wlan0 interface began to work after around 5 mins which leads me to assume that this is something on how the networking on resinos is setup.

Any leads on how to debug this would be much appreciated!
