I have a connection of 100 Mbps in download, with all the pc go to 98mbps.... with BT3 I go to maximum 20mbps .... 3 meters away from the Router Netgear D7000 .... bad wi-fi or are they all so ?
thank you
Don't expect too much from the tiny integrated wifi card.
Use the LAN port or connect an usb wifi adapter. These are available with AC wifi and need the usb3-port.
I start to think it's broken because the iMac with the online test always give 100 \ 20, or almost ... but not 20 \ 20Mbps .......... ok bad wi-fi but it's too slow. .. Lan maximum speed reaches 7MBs :(
Thank you
