I have a Problem with one of my link using c5c ptp , its says Wireless disassociated and Wireless associated. please help I experienced disconnection when i see the logs

Could you post some more details about the link?

Distance between AP and Client, RSSI, Chains, antenna sizes, TX power, etc. Would all be helpful. The log you are showing is also complaining about Ethernet issues, you might want to check that out as well.
