Connected to the router but there is no Internet connection. Can I get some help please?

My internet has been really dodgy for the last couple months. We have around 20 devices connected (not a small buisness just really large family) and most of the computers on the network are connected to the router but they have no internet. A small yellow triangle appears on the wifi icon and the connection reads: no internet, secured. Is this a problem with my modem, router, or the ISP? Or is there not enough information?

Thanks for your time!

the yellow triangle means you need to install driver for the wireless also did you check in your router if this device is on the wireless permit list thye other thing with so many device on the same router do you use a switch to connect all of them to the router .

I don't use a switch and all the computers have connected and had internet for a time before they started losing internet. And I can usually fix the problem by having windows perform a network reset on the computer.

post a picture of the setup connection from isp to all pc could be that your router have issue to handle all of those in the same time .
