I'm connecting my MacBook to the internet via a current generation Apple Airport Extreme (late 2013). When I'm standing next to the Airport, my Mac's wifi indicator shows full signal strength (duh!) and I get excellent download speeds (30-50mbps). When I'm on the other side of the house, my MacBook still shows full signal strength but I can barely load anything (.25mbps... if I'm lucky)!
What gives? Why would the signal be strong but I can't download anything?
