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,

    Hello Klaatu1947,

    I found a good resource to help troubleshoot the wifi issue you are experiencing with the iPhone 5 named

    iOS: Troubleshooting Wi-Fi networks and connections found here: http://support.apple.com/kb/ts1398


    I would recommend the Basic troubleshooting section first, and then the section farther below labeled After joining a Wi-Fi network, you notice the signal strength is weak or fluctuates.


    Within that section is another link to an article to check for potential sources of interference on that 5GHz spectrum named AirPort and Bluetooth: Potential sources of interference found here: http://support.apple.com/kb/HT1365



    Take care,
