Hello,
Thanks for the information.
It is hard to say for sure why this specific device fails to connect. However, from the logs, it seems that one of the devices 'did not acknowledge authentication response' from the RUT. So something with the compatibility of that device can be off.
First, could you try to disable 'Allow legacy 802.11b rates' in WiFi settings? You can edit the configuration file by connecting to the device via CLI/SSH and executing:
This will open the file in the text editor. Press 'i' so start editing. Find your 'config wifi-iface' and make sure you have/add:
- option disassoc_low_ack '0'
Press 'esc', type ':wq', and press 'enter' to save settings.
You can also try changing other settings, such as wifi mode (protocol, for example from 802.11g+n to 802.11g, etc), channel bandwidth (20/40Mhz), changing encryption/cipher, etc.
It would be great if you could download a backup file (so that you can revert later on), and try updating to the latest firmware version with 'keep settings' turned off. Let me know if it works on the latest version. There were plenty of changes made to how WiFi works. You can then revert to legacy and upload a backup file to restore your configurations.
Kind Regards,
Andzej
