Internet is not stable

Hello i have connected my ISP to peplink and distributed to my switches and access point but internet is not stable if connect via peplink how to identify the issue .

I am using peplink balance 730.

Can you draw a diagram of your network showing what internet connections you have connected please. and Share your outbound policies / config.

Then advise what happens when it goes wrong? What isn’t stable exactly?

Hi Martin thanks for your command will drop network diagram and approch mean while i am having 1 gig spped and connected to 8 Access point will be an issue for overload.

Note we have 300 device connected.
