I've just had BT Infinity installed and now my wireless printer,which worked perfectly before and still does when attached to my computer, now doesn't. I've tried un-installing it and re-installing it, spent HOURS on the phone to the help desk (please don't ask me to phone them again). I've made sure the printer is switched on and attached to an ethernet port on the back of the hub but all it says it that it can't find the printer. I'M TEARING MY HAIR OUT!!!!!!!! HELP!!!!!!!!
