intermittent WIFI disconnections

Hi,

I have recently bought the CRS125-24G-1S-2HnD-IN and have been so far very happy with it except for its wireless connectivity. I am having frequent. irregular WIFI disconnections and makes the situation frustrating especially when users are connecting via VPN over the same mentioned WIFI connection.Am sending attached the log file.

What are all the items that should I check please? I need to resolve this case in some way or another for sure since we cannot afford having these type of disconnections

thanks in advance for your assistance,

Geoffrey
