Cannot access wireless printer through bt homehub 5
I have recently bought a Brother DCP-J4120DW all in one wireless printer/scanner. Although it has connected to the home hub 5 without a problem, when I try to connect to the device from my iMac or MacBook wirelessly, nothing happens. Reading various posts on this, and other sites, the problem seems to be with the home hub. As a complete novice regarding these thing I would be obliged to anyone who can shed light on this, and explain it in layman's terms.
Thank's, in advance.
