wifi configuration on beaglebone black.

[Madhu K]

Hi All,

I was trying to configure wifi on beaglebone black board. But i am facing below problems.

I am using TP-LINK TL-WN823N adaptor.

Beaglebone black wifi setup steps :

1) Downloaded the stable kernel 4.4.2 from git.

2) Compiled the kernel and loaded new kernel to beaglebone black.

3) Downloaded the rlt8192eu ( TL-WN823N ) driver code from git.

4) Compiled the driver code for beaglebone black and inserted the module to new kernel.

5) Inserted TL-WN823N adapter to beaglebone black.

Problems :

1) I am getting below messages, i don't know what exactly that message indicates.

Hello,

You might have to update the firmware on your WiFi dongle.

Hi,

Thank you so much for your response.

How do you say, the issue is because of firmware only.

Thanks
Madhu
