iPhone WIFI reception problems
There is something amiss in the design of the iPhone 5 WIFI design. I can walk to all of the remote areas of my house with my iPhone 4 (on the 2.4 Ghz band) and recieve maximum signal level, as soon as a go up the steps in my house the iPhone5 drops to one bar. The good news is that the iPhone 5 supports the 5 Ghz band. The bad news is that the only way I can connect to the 5Ghz band is to be in the same room as the router. I am using an Apple Airport Extreme, current firmware level (7.6.3).
All other WIFI devices in my house function without a problem, including a Nest thermostat, two WIFI TVs, iPad, and iMac.
The iPhone is at the current IOS level,
