Range
I bought this router to replace a 2011 Netgear N600 that went out. The wireless range of the Netgear reached my detached office and upstairs bedroom. This router does not.. The Best Buy Salesman said this router should have significantly better range. I am seeing far less range. Is there something I can try to fix the range issue before I return it? If I do return this one, any suggestions on what I should get to improve the range compared to the old Netgear?
