Connected a MacBook or iPhone to the AirPort Express at 5 GHz, when the device is moving away the Wi-Fi connection continues to be very good (with the maximum signal it means 5 lines), . . . but the access to Internet is completely lost.
By contrast in 2,4 GHz it works perfectly, without any problem.
Incredible . . . but true !
AirPort Express 802.11n (2nd generation)
Not incredible at all. You may not be aware that 5 GHz signals are much weaker than 2.4 GHz signals.
So, 5 GHz will work well when the wireless router and wireless device are in the same room....or close proximity to each other.
But, if the wireless device moves a few rooms away from the wireless router......the 2.4 GHz signal is probably 8-10 times stronger than the 5 GHz signal at that location.

Thank you for your quick and interesting response. I did not remember this feature of RF waves.
But how is possible that the signal strenght indicator in the MacBook shows the maximum (that is 5 black lines), meaning the Wi-Fi connection between the computer and the AirPort Expres is excellent ?

Signal strength is not the same as signal quality ... and it is the latter that determines the overall data transfer rate your computer will have over that connection.
This is somewhat analogous to being at a music concert with a very noisy crowd. The band may be playing very loudly (signal level), but because of the crowd noise what you can actually hear clearly (signal quality) is not what you expected.
Thank you for your answer. I understand now why there is no connection to Internet with the high signal strength.

The "bars" at the top of screen are there pretty much for "show". They might indicate signal strength......but they tell you nothing about the noise content in the signal. Best to ignore the "bars".
Thank you once more !
