slow network connection suddenly
Im a relativly new technician and have a job at a primary school as there main technician.
Basically everything was working fine yesterday then overnight its not. I got a phone call earlier saying the internet isnt working. When i got there i found out a few computers are working fine and all the rest are not. They have a really slow network connection and internet connection or sometimes no connection. Ive attached a basic plan of everything below.
For some reason there is a computer in the main building that seems to be patched at cab 1 (no idea why - its quite an old building though) Everything connected to cab 1 works fine. Cab 2 onwards is when it gets slow. So im asuming its something to do with the main link? The two main buildings are connected via an ethernet connection BUT the cable goes into what looks like a fibre box which then goes into another smaller box (Via fibre) which then goes into the switch via ethernet (Ive never seen this set up before)
I havnt gone in today really to try anything - but it obviously needs to get working tomorrow so thought id come on here to get some more ideas as to what it would be.
Thanks for any responses.
