pages not loading when many users are trying to access internet at same time
I've been having an issue with the internet at our school for quite some time now and I have not been able to find the cause of the problem.
When a full class (20 users) tries to access the internet, the pages crash and do not load, and the internet becomes extremely slow. This issue has been regular for a couple of months, but was not present before that. When a full class is not using the internet, the internet works brilliantly.
We have 40 Mbps fibre broadband which should be capable of allowing all our users to access the internet at once, as many of the sites are not usually that large.
We have a Cisco RV180W router, which is connected to a 24 port Gigabit switch, which connects to all the classroom computers. The computers run Windows 10 and use Google chrome as the browser. The computers do not access the internet through a proxy server.
I am trying to find out the source of the problem, and I'm not sure what it can be. At first, I thought it was the switch, as we had a 100Mbps switch, so I swapped that for a Giga switch. I also tried replacing the router for a similar Netgear one and had the same problem. The service provider has said the connection is fine from their side. I also tried using different DNS servers. How can I get to the bottom of this? Are there any tools I can use to diagnose this?
Any help would be much appreciated. Thanks
