I'm attaching pictures of the network room that's set up in an apartment building. There are about 30 units, wired with ethernet ports in all rooms. Routers are set up in bridge mode, and average speed is 5mbps download and 1mbps upload. Sometimes it will crawl to 1-2 down and .5 up. I'm trying to help management sort it out, because when we connect a modem via ethernet directly into a switch port and test the speed, it is 15 down 2 up. They are clueless about what all these devices are, and so am I. I'm assuming there's a VPN gateway, firewall, in addition to the switch and modems. Can any help help identify each piece of equipment?
