There is a 12dbi difference between chains. It could be an alignent problem. A wireless status picture would be more interesting…

Thank you for reply, I have added 2x wireless status pics..thx

At this stage mostly a client has a defectiv wireless card.
Check each client separatly with hughe traffic to identify the bad client.
For a intermediate solution until you can change the client board, increase tdma period size.

Also check if the chains H/V matches on all devices
