Basebox5 Flapping between LAN and WLAN

Hi,

we have a basebox5 with 90° sector of 21 dBi. In the basebox we have 35 clients, that are 33 SXT 5HnD and 2 Sextant, the nearest is 500 meters, the farthest is a sextant at 10Km.

All works ok, until yesterday, at certain times of the day, always different, we lose a lot of ping from the clients to the basebox. No ping lost if a client try to ping an other client. No ping lost if from the backbone i am trying to ping the basebox from LAN.

What do you think about this?

Thanks!

Hello campa4bt

Please post your full config, so we can see if there is no problem there. Thanks

This is the basebox:
