I just bought the 6th generation AirPort Extreme to replace my 5th generation and AirPort Express. I have my router in my basement at one end of the house (where my home run is for all my cabling) and previously had the AirPort Express on the main (only) floor of my house extending my wifi via cat5e as we couldn't get signal in our bedroom which is at the other end of the house. I read that the 6th generation redesigned ac model was better for signal. I can confirm that it is as we can now get Internet in our bedroom without needing the Express anymore but only if we both turn off wifi and turn it back on again on our iPhone 5's when in the bedroom. Anyone know why we have to turn wifi off and back on to get Internet when in the bedroom? Our home is about 43' long and is ranch style with a poured finished basement built in the mid 70's. I have it set to auto channel but have the same problem when manually selecting a channel that is not used by any other wifi network around me according to iStumbler.
