What is going on with my networking setup? Setup is old: cat 3 wiring (double pair so at least 100 speed) going to the places in the house. I just don't know what the items are they are connected to. One looks like a bridge (the black one). What is the one on the bottom (thumbnail gives closeup)? Why do you need both?Bought new synology rt2600ac router, getting ds718+ with WD red 4TB. Getting TL-SG1008P PoE switch to run 3-4 ip cameras. Going to pull some new cat wiring, but don't understand the setup. Thanks.
