I can't get my one computer to have excellent signal strength in the other room. How can this be accomplished or is this even necessary? Much of the time it is low and sometimes it is good. Once in a blue moon I have seen it very good. I have the Dlink DI 524 with a usb antenna on my desktop. It is about 30 or so feet away from the router. What do you suggest to boost the signal? Should I switch to a different antenna on my receiving computer? Suggestions?
