MASSIVE drop in speed between being plugged into the main switch and a network port
I've come across a problem in that when im plugged into the main switch and do speedtest i get 46meg download speeds. From the switch cabling goes to a patch panel and then to network ports over the building. if i plug into the network ports in rooms and run speedtest i get around 10meg download speeds. So i'm clearly losing a massive amount of speed through poor wiring?
If so what does that mean, is there anything i can check or is it a case of i'd have to get someone in to rewire the whole place? What is it that could have been done so bad to account for this kind of loss do you think so that i can look out for it in the future?
Any help would be appreciated.
