I subscribe to the vm 200mbps package but can only get 70-80 mbps. I have the hub 3.0. My laptop is hardwired to the hub using cat6 ethernet cable through a usb 3.0 gigabit ethernet adaptor. Network adaptor is realtk 802ae wireless LAN 802.11ac pci-e nic. All of which means nothing to me. So why can i get higher download speed?
