I recently purchased an HP1920-24g switch for my home network. I setup 1 vlan and only assigned 2 ports to it, when i plug into the ports with vlan my speedtest caps at 150mbps (my internet speed is 300/30). However, when I plug into any of the other ports which is technically assigned to default Vlan001 I get my max speed of around 350mbps. Is it normal to lose half your bandwidth routing through vlans? I only have 1 PC plugged in at the moment.
My network:
Arris Modem > Ubiquiti Edge Router Lite > HP 1920-24g Switch > PC
