Hey there folks.

So the above combo, Noble Numbat, Lenovo Ideapad 1, with RTL8822CE 802.11ac PCIe Wireless Network Card is giving horrendous WiFi speeds.

Now, the router is about 4 metres away, 12 - 14 feet, the other side of a door, so.... Would switching to 2.4 GHZ help and then if so...... HOW?

How have you measured "horrendous WiFi speeds"? What test have you run to determine it's "terrible"?
